  • UITableViewCell imageView.contentMode doesn't work in 3.0

    - by JustinXXVII
    In UITableViewCellStyleDefault, setting the contentMode on the imageView has no result. If I change my build SDK to version 3.1, everything again works. I don't get any warnings or errors when compiling on 3.0 but this code: cell.imageView.contentMode = UIViewContentModeScaleAspectFit; cell.imageView.image = [UIImage imageNamed:[[NSString stringWithFormat:@"%@head.jpg",[gametype objectAtIndex:indexPath.row]]lowercaseString]]; seems to default to the UIViewContentModeCenter, so all of my pictures exceed the cell boundaries and encroach on neighboring cells. Let me reiterate that if I change my target to 3.1 everything works correctly and all pictures are scaled accordingly to fit in the default imageView Is this a known bug?

  • Showing login view controller before main tab bar controller

    - by Padawan
    I'm creating an iPad app with a tab bar controller that requires login. So on launch, I want to show a LoginViewController and if login is successful, then show the tab bar controller. This is how I implemented an initial test version (left out some typical header stuff, etc)... AppDelegate.h: @interface AppDelegate_Pad : NSObject <UIApplicationDelegate, LoginViewControllerDelegate> { UIWindow *window; UITabBarController *tabBarController; } @property (nonatomic, retain) IBOutlet UIWindow *window; @property (nonatomic, retain) IBOutlet UITabBarController *tabBarController; @end AppDelegate.m: @implementation AppDelegate_Pad @synthesize window; @synthesize tabBarController; - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { LoginViewController_Pad *lvc = [[LoginViewController_Pad alloc] initWithNibName:@"LoginViewController_Pad" bundle:nil]; lvc.delegate = self; [window addSubview:lvc.view]; //[lvc release]; [window makeKeyAndVisible]; return YES; } - (void)loginViewControllerDidFinish:(LoginViewController_Pad *)loginViewController { [window addSubview:tabBarController.view]; } - (void)dealloc {...} @end LoginViewController_Pad.h: @protocol LoginViewControllerDelegate; @interface LoginViewController_Pad : UIViewController { id<LoginViewControllerDelegate> delegate; } @property (nonatomic, assign) id <LoginViewControllerDelegate> delegate; - (IBAction)buttonPressed; @end @protocol LoginViewControllerDelegate -(void)loginViewControllerDidFinish:(LoginViewController_Pad *)loginViewController; @end LoginViewController_Pad.m: @implementation LoginViewController_Pad @synthesize delegate; ... - (IBAction)buttonPressed { [self.view removeFromSuperview]; [self.delegate loginViewControllerDidFinish:self]; } ... @end So the app delegate adds the login view controller's view on launch and waits for login to call "did finish" using a delegate. The login view controller calls removeFromSuperView before it calls didFinish. The app delegate then calls addSubView on the tab bar controller's view. If you made it up to this point, thanks, and I have three questions: MAIN QUESTION: Is this the right way to show a view controller before the app's main tab bar controller is displayed? Even though it seems to work, is it a proper way to do it? If I comment out the "lvc release" in the app delegate then the app crashes with EXC_BAD_ACCESS when the button on the login view controller is pressed. Why? With the "lvc release" commented out everything seems to work but on the debugger console it writes this message when the app delegate calls addSubView for the tab bar controller: Using two-stage rotation animation. To use the smoother single-stage animation, this application must remove two-stage method implementations. What does that mean and do I need to worry about it?

  • cells order changes in UITableView after reloadSections: method

    - by user304895
    I'm having a problem using a grouped UITableView, and after 3 days of searching, I didn't found the solution... Actually, I have a Grouped table, composed of two sections : The first section contains a UISegmentedControl with three buttons : button0, button1 and button2. When clicking on the button0, I want to show two cells in the second section, with embedded UITextField in each cell. When clicking on the button1, I want to show one cell in the second section with an embedded UITextField. When clicking on the button2, I have to show the camera in ModalView (I think it will be ok). I've also put placeholders in each UITextField. Each time a button is clicked, I call a pickOne: method in order to update my view. In this method, I construct a NSIndexSet with NSRange of (1, 1), and then I call the reloadSections: method from the UITableViewController with NSIndexSet as a parameter. When the view appears for the first time, everything is ok, but when I click many times on the buttons, the order of the cells changes (cells containing the two textFields for the button0), and the new placeHolders are written over the old ones. Even more, sometimes when I click on the button0, it shows me only the second cell... Do you have any idea ? or need some code ? Thank you :)

  • Using Mapping Models to migrate between Core Data Object Models

    - by westsider
    I have a fairly simply scheme. Essentially, Run <-- Data (where a Run holds a data, e.g., Temperature, sampled from some sort of sensor). Now, it seems that sensors can have more than one measurement (e.g., Temperature and Humidity). So, a single Run could have multiple data samples. Hence, Run <-- Sample and Sample <-- Data. (And for simplicity I am leaving Run <-- Data in place, for now.) If I create a new mapping model, then things generally work - except that no new Samples are created, no relationships are established between Runs and Samples nor between Samples and Datas. I am trying to get mapping model to migrate my model but even the slightest change to the generated mapping model results in Cocoa error 134110. For example, if I take the "Sample" mapping (which has no Source) and set its Source to 'Run' (so that I can set Sample's inverse relationship 'run' appropriately) then the mapping changes its name to "RunToSample". There are two relationships handled in this mapping: data and run. The data property gets set automatically to FUNCTION($manager, "destinationInstancesForEntityMappingNamed:sourceInstances:" , "DataToData", $source.dataSet) Following this example, I set the run property to FUNCTION($manager, "destinationInstancesForEntityMappingNamed:sourceInstances:" , "RunToRun", $source) Similarly, I set the 'sample' property mapping in RunToRun to FUNCTION($manager, "destinationInstancesForEntityMappingNamed:sourceInstances:" , "RunToSample", $source) and the 'sample' property in DataToData to FUNCTION($manager, "destinationInstancesForEntityMappingNamed:sourceInstances:" , "RunToSample", $source.run) So, what, I wonder, is going wrong? I have tried various permutations, such as leaving the 'inverse' relationships unspecified. But I continue to get the same error (134110) regardless. I imagine that this is a lot easier than it seems and that I am missing some fundamental but minor piece. I have also tried subclassing NSEntityMigrationPolicy and overriding -createDestinationInstancesForSourceInstance: but these efforts have met with much the same results. Thanks in advance for any pointers or (relevant :-) advice.

    Hi there!

  • Core Location Best Placement and User Interruption

    - by b.dot
    Hi All, My application uses Core Location in three different views. It's working perfectly. In my first view, I subclass the CLLocationManager and use protocol methods for location updates to my calling class. Before I install the framework and code in my other classes, I was wondering: Is the protocol method the best way? What happens to the Core Location execution if the user exits the view or quits the app while it's trying to get a location fix? Is the location task terminated with the GPS system turned off immediately? If the user simply switches to another view, is it OK to assume that I can start Core Location in the next view without regard to the last? Where should the first update location call be placed. Should the application delegate instantiate the CLLocation Manager class using protocol so that it can update any of the views chosen or should each class instantiate the manager. Any feedback would be appreciated. Thanks.

  • UIScrollView ImageView with pins on top

    - by Koppo
    To all, I have a UIScrollView which has a UIImageView. I want to show pins on this imageView. When I add pins as subviews of the ImageView everything is great except for when you zoom the scale transform happens on the pins also. I don't want this behavior and want my pins to stay the same. So I choose to add the Pins to another view which sits on top of the ImageView and is also a subview of the UIScrollView. The idea here if you will imagine is to have a layer which hovers over the map and won't scale yet show pins over where I plot them. The pin when added to the layer view don't cale if the ImageView scales. However the issue then bceomes the position of the pins doesn't match the original origin x/y as the ImageView has had a scale transform. Basically this is a custom map of a place with Pins. I am trying to have the Pins float over and not zoom in and out over my ImageView yet remember where I placed them when the zoom happens. Some code scrollView = [[UIScrollView alloc] initWithFrame:viewRect]; scrollView.delegate = self; scrollView.pagingEnabled = NO; scrollView.scrollsToTop = NO; [scrollView setBackgroundColor:[UIColor clearColor]]; scrollView.clipsToBounds = YES; // default is NO, we want to restrict drawing within our scrollview scrollView.bounces = YES; scrollView.autoresizingMask = UIViewAutoresizingFlexibleHeight; scrollView.indicatorStyle = UIScrollViewIndicatorStyleWhite; imageViewMap = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"image.png"]]; imageViewMap.userInteractionEnabled = YES; viewRect = CGRectMake(0,0,imageViewMap.image.size.width,imageViewMap.image.size.height); //viewRect = CGRectMake(0,0,2976,3928); [scrollView addSubview:imageViewMap]; [scrollView setContentSize:CGSizeMake(viewRect.size.width, viewRect.size.height)]; iconsView = [[UIView alloc] initWithFrame:imageViewMap.frame]; [scrollView addSubview:iconsView]; Code to add Pin later on some event. [iconsView addSubview:pinIcon]; I am stuck in trying tp figure out how to to get my pins to hover on the map without moving when the scale happens. Thanks

  • timeIntervalSinceDate Accuracy

    - by mmccomb
    I've been working on a game with an engine that updates 20 times per seconds. I've got to point now where I want to start getting some performance figures and tweak the rendering and logic updates. In order to do so I started to add some timing code to my game loop, implemented as follows... NSDate* startTime = [NSDate date]; // Game update logic here.... // Also timing of smaller internal events NSDate* endTime = [NSDate date]; [endTime timeIntervalSinceDate:startTime]; I noticed however that when I timed blocks within the outer timing logic that the time they took to execute did not sum up to match the overall time taken. So I wrote a small unit test to demonstrate the problem in which I time the overall time taken to complete the test and then 10 smaller events, here it is... - (void)testThatSumOfTimingsMatchesOverallTiming { NSDate* startOfOverallTime = [NSDate date]; // Variable to hold summation of smaller timing events in the upcoming loop... float sumOfIndividualTimes = 0.0; NSTimeInterval times[10] = {0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0}; for (int i = 0; i < 10; i++) { NSDate* startOfIndividualTime = [NSDate date]; // Kill some time... sleep(1); NSDate* endOfIndividualTime = [NSDate date]; times[i] = [endOfIndividualTime timeIntervalSinceDate:startOfIndividualTime]; sumOfIndividualTimes += times[i]; } NSDate* endOfOverallTime = [NSDate date]; NSTimeInterval overallTimeTaken = [endOfOverallTime timeIntervalSinceDate:startOfOverallTime]; NSLog(@"Sum of individual times: %fms", sumOfIndividualTimes); NSLog(@"Overall time: %fms", overallTimeTaken); STAssertFalse(TRUE, @""); } And here's the output... Sum of individual times: 10.001377ms Overall time: 10.016834ms Which illustrates my problem quite clearly. The overall time was 0.000012ms but the smaller events took only 0.000001ms. So what happened to the other 0.000011ms? Is there anything that looks particularly wrong with my code? Or is there an alternative timing mechanism I should use?

  • Odd background image resizing on animating UIView

    - by Woody
    I have a UIView in the middle of a view that I am using as a game playing area (in a 2d cocoa view). This image has a background image of the same size as the view. Resizing the view I use animation to make it look smooth (and that works fine). However, when the animation starts, the background image immediately changes size, tiling or being clipped to a size that when the animation finishes, the background image is physically the same size. I don't want this, I want the image to always fit the view, regardless of the view size. UIImage *bgImage = [UIImage imageNamed:@"head.png"]; ... // resize the image returning another image self.view.backgroundColor = [[UIColor alloc] initWithPatternImage:resizedImage]; [UIView beginAnimations:@"resizeView" context:nil]; [UIView setAnimationDuration:.5]; int localViewSize = ... // work out view sizes self.view.frame = CGRectMake(... ,localViewSize,localViewSize); [UIView commitAnimations]; It looks very odd as it jumps to a different size, then animates to the original size. I am guessing that maybe I would have to make a separate view underneath my main view but is that the only way?

  • Trying to force redraw of UITableViewCell

    - by Suresh
    I found this post on Beveled UITableViewCells from http://news.selectstartstudios.com/beveled-uitableviewcells/. I'm using the technique to reduce the width of the cells, and for the most part it works great. However, I have a small problem. Sometimes the cells are not redrawn properly. For example, even though a cell is supposed to be a "middle" cell, it is drawn as a "top" cell: yfrog.com/f1screenshot20100424at100 How can I fix this? I have tried forcing the cell to redraw via [cell setNeedsDisplay], [cell setNeedsLayout], [tableView reloadRowAtIndexPath:withAnimation:], [cell drawrect:], and [tableView drawRect:atIndexPath]. I am out of ideas. Thanks again!

  • How to have two UIPickerViews together in one ViewController?

    - by 0SX
    I'm trying to put 2 UIPickerViews together in one ViewController. Each UIPickerView has different data arrays. I'm using interface builder to link the pickers up. I know I'll have to use separate delegates and dataSources but I can't seem to hook everything up with interface builder correctly. Here's all my code: pickerTesting.h #import <UIKit/UIKit.h> #import "picker2DataSource.h" @interface pickerTestingViewController : UIViewController <UIPickerViewDelegate, UIPickerViewDataSource>{ IBOutlet UIPickerView *picker; IBOutlet UIPickerView *picker2; NSMutableArray *pickerViewArray; } @property (nonatomic, retain) IBOutlet UIPickerView *picker; @property (nonatomic, retain) IBOutlet UIPickerView *picker2; @property (nonatomic, retain) NSMutableArray *pickerViewArray; @end pickerTesting.m #import "pickerTestingViewController.h" @implementation pickerTestingViewController @synthesize picker, picker2, pickerViewArray; - (void)viewDidLoad { [super viewDidLoad]; pickerViewArray = [[NSMutableArray alloc] init]; [pickerViewArray addObject:@" 100 "]; [pickerViewArray addObject:@" 200 "]; [pickerViewArray addObject:@" 400 "]; [pickerViewArray addObject:@" 600 "]; [pickerViewArray addObject:@" 1000 "]; [picker selectRow:1 inComponent:0 animated:NO]; picker2.delegate = self; picker2.dataSource = self; } - (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)picker; { return 1; } - (void)pickerView:(UIPickerView *)picker didSelectRow:(NSInteger)row inComponent:(NSInteger)component { } - (NSInteger)pickerView:(UIPickerView *)picker numberOfRowsInComponent:(NSInteger)component; { return [pickerViewArray count]; } - (NSString *)pickerView:(UIPickerView *)picker titleForRow:(NSInteger)row forComponent:(NSInteger)component; { return [pickerViewArray objectAtIndex:row]; } - (void)didReceiveMemoryWarning { // Releases the view if it doesn't have a superview. [super didReceiveMemoryWarning]; // Release any cached data, images, etc that aren't in use. } - (void)viewDidUnload { // Release any retained subviews of the main view. // e.g. self.myOutlet = nil; } - (void)dealloc { [super dealloc]; } @end And I have a separate class for the other datasource. picker2DataSource.h @interface picker2DataSource : NSObject <UIPickerViewDataSource, UIPickerViewDelegate> { NSMutableArray *customPickerArray; } @property (nonatomic, retain) NSMutableArray *customPickerArray; @end picker2DataSource.m #import "picker2DataSource.h" @implementation picker2DataSource @synthesize customPickerArray; - (id)init { // use predetermined frame size self = [super init]; if (self) { customPickerArray = [[NSMutableArray alloc] init]; [customPickerArray addObject:@" a "]; [customPickerArray addObject:@" b "]; [customPickerArray addObject:@" c "]; [customPickerArray addObject:@" d "]; [customPickerArray addObject:@" e "]; } return self; } - (void)dealloc { [customPickerArray release]; [super dealloc]; } - (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)picker2; { return 1; } - (void)pickerView:(UIPickerView *)picker2 didSelectRow:(NSInteger)row inComponent:(NSInteger)component { } - (NSInteger)pickerView:(UIPickerView *)picker2 numberOfRowsInComponent:(NSInteger)component; { return [customPickerArray count]; } - (NSString *)pickerView:(UIPickerView *)picker2 titleForRow:(NSInteger)row forComponent:(NSInteger)component; { return [customPickerArray objectAtIndex:row]; } @end Any help or code examples would be great. Thanks.

  • UIWebView Page Control

    - by Jack
    Hi, I would like to use a UIWebView to display some files (PDF, PPT, DOC) and would like to have the ability to scroll using external controls (ie a couple of buttons that, when pressed skip back and forward a page) and display the current page in a UITextView. Is this possible? I have no experience with javascript, but a friend of mine has suggested that this might be a useful approach. Is his suggestion valid? JP

  • How to set up a user Quartz2D coordinate system with scaling that avoids fuzzy drawing?

    - by jdmuys
    This topic has been scratched once or twice, but I am still puzzled. And Google was not friendly either. Since Quartz allows for arbitrary coordinate systems using affine transform, I want to be able to draw things such as floorplans using real-life coordinate, e.g. feet. So basically, for the sake of an example, I want to scale the view so that when I draw a 10x10 rectangle (think a 1-inch box for example), I get a 60x60 pixels rectangle. It works, except the rectangle I get is quite fuzzy. Another question here got an answer that explains why. However, I'm not sure I understood that reason why, and moreover, I don't know how to fix it. Here is my code: I set my coordinate system in my awakeFromNib custom view method: - (void) awakeFromNib { CGAffineTransform scale = CGAffineTransformMakeScale(6.0, 6.0); self.transform = scale; } And here is my draw routine: - (void)drawRect:(CGRect)rect { CGContextRef context = UIGraphicsGetCurrentContext(); CGRect r = CGRectMake(10., 10., 11., 11.); CGFloat lineWidth = 1.0; CGContextStrokeRectWithWidth(context, r, lineWidth); } The square I get is scaled just fine, but totally fuzzy. Playing with lineWidth doesn't help: when lineWidth is set smaller, it gets lighter, but not crisper. So is there a way to set up a view to have a scaled coordinate system, so that I can use my domain coordinates? Or should I go back and implementing scaling in my drawing routines? Note that this issue doesn't occur for translation or rotation. Thanks

  • viewDidAppear called when popping navigationController

    - by Tiago
    I'm having a bit of a problem with the viewDidAppear: method. I have a tabBarController with navigationControllers on each tab, and I have an action that requires that all the navigation controllers pop to their rootViewControllers (programmatically). The problem is that when they pop each navigation controller, the rootViewController's viewDidAppear get's called without it actually being shown. This causes them to do some stuff they were not supposed to (like showing alerts) unless they are actually shown. Besides having to check the currently selected tabBar item, is there any other way to solve this? Thanks.

  • UISwitch within UIScrollview nearly impossible to use....

    - by samsam
    Hi there. I'm using a UISwitch-Component at the bottom of a view that sits within a UIScrollView. Now the problem that appeared, is that the switch is nearly impossible to swipe because the UIScrollView seems to dominate the userinput. Switching works very well by tapping the switch, but from my point of view, most users "switch" the UISwitch instead of tapping. Did anyone of you face the same / or similar problems and managed to come up with a solution? thx in advance sam

  • How can I tell when a UIWebView has finished drawing to a context?

    - by phopkins
    In my code I'm trying to show a UIWebView as a page is loading, and then, when it's done, capture an image from the web view to cache and display later (so I don't have to reload and render the web page). I have something along the lines of: CGContextRef context = CGBitmapContextCreate(…); [[webView layer] renderInContext:context]; CGImageRef imageRef = CGBitmapContextCreateImage(context); UIImage *image = [UIImage imageWithCGImage:imageRef]; The problem I'm running into is that, due to UIWebView's tiling, sometimes only half of the page is rendered to the context by the time I capture the image. Is there a way to detect or block on UIWebView's background rendering thread so that I can get the image only after all of the rendering has finished?
