  • initWithCoder breaking my touch events (touchBegan, touchMoved, etc)

    - by Adam
    So I have a UIView that has been setup, and in each touch event handler I have an NSLog fire off a message to the console. - (void) touchesBegan:(NSSSet*)touches withEvent:(UIEvent*)event { NSLog(@"touchesBegan"); } And that pretty much works as expected. But once I implement initWithCoder (even blank) - (id)initWithCoder:(NSCoder*)coder { return self; } I no longer receive the message to my console (or can hit breakpoints obviously). This is my first app so I'm probably missing something dumb, but I've looked through various example apps and I don't appear to be missing any code that would re-enable touch events.

  • UITableView scrollable background , UITableViewCell transparency

    - by f0rz
    Hi! In my UITableView I have custom cells. My UITableView have a repeatable background myTableView.backgroundColor = [UIColor colorWithPatternImage: [UIImage imageNamed: @"backg.png"]]; I set my cells to have their background (clear); UIView *backView = [[[UIView alloc] initWithFrame:CGRectZero] autorelease]; backView.backgroundColor = [UIColor clearColor]; cell.backgroundView = backView; This makes the cell have the same background as the TableView.. Problem is; That seems that every cell loads myTableView.backgroundColor once again. And the background are not being repeatble as it should. I want to have the cells totally with no background at all, instead they loads up myTableView.backgroundColor once again. Here is one example. Can anyone help me?

  • Dynamic name of NSMutableDictionary?

    - by Bruno
    Hi everyone I load from a txt file many info, and I would like, if possible, to dynamically create NSmutable dictionary with the elements of the txt. For example, each is like that: id of element | date | text What I'm asking is the equivalent of the NSString stringWithFormat:. Can we do the same for an Mutable Dictionary? To be more practical, let's say the NSString *date is equal to "23/12/2009" (for europe). I want to create a dictionary called 23/12/2009 without declaring *23/12/2009 but just something like dictionaryWithFormat: @"%@", date]; I'm stuck on this, and I don't even know if it is possible. If not, what's the best way to approach that? Thanks everyone Regards

  • Regular Expression doesn't match

    - by dododedodonl
    Hi All, I've got a regular expression in my cocoa-touch app (using RegexKitLite). NSString *week = [[NSString alloc] initWithFormat:@"%@", [pageContent stringByReplacingOccurrencesOfRegex:@"<select name=\"week\" class=\"selectbox\" style='width:134' onChange=\"doDisplayTimetable(NavBar, topDir);\">(.+?)<option value=\"(.+?)\">(.+?)</option>" withString:@"$2"]]; I expect it to match with the section of this (what is in NSString pageContent): <span class="selection"> <nobr> Periode<br> <span class="absatz"> &nbsp;<br> </span> <select name="week" class="selectbox" style='width:134' onChange="doDisplayTimetable(NavBar, topDir);"> <option value="14">17-5 - 16-7</option> </select> </nobr> </span> But it doesn't... I need the value of the option, it is possible that there is more than one (in that case I need them both separated by a ,. Can someone help me out? Regards, Dodo

  • Why are controls (null) in awakeFromNib?

    - by fuzzygoat
    This is a follow on from another question regarding why I could not set UIControls in awakeFromNib. The answer to that is that as you can see below the controls are nil in the awakeFromNib, although they are initialised to the correct objects by the time we get to viewDidLoad. I setup the view the same as I always do, should I be doing something different to access them here, the xib(nib) was designed and saved with the current version of Image Builder. CODE: @interface iPhone_TEST_AwakeFromNibViewController : UIViewController { UILabel *myLabel; UIImageView *myView; } @property(nonatomic, retain)IBOutlet UILabel *myLabel; @property(nonatomic, retain)IBOutlet UIImageView *myView; @end . @synthesize myLabel; @synthesize myView; -(void)awakeFromNib { NSLog(@"awakeFromNib ..."); NSLog(@"myLabel: %@", [myLabel class]); NSLog(@"myView : %@", [myView class]); //[myLabel setText:@"AWAKE"]; [super awakeFromNib]; } -(void)viewDidLoad { NSLog(@"viewDidLoad ..."); NSLog(@"myLabel: %@", [myLabel class]); NSLog(@"myView : %@", [myView class]); //[myLabel setText:@"VIEW"]; [super viewDidLoad]; } OUTPUT: awakeFromNib ... myLabel: (null) myView : (null) viewDidLoad ... myLabel: UILabel myLabel: UIImageView Much appreciated ... gary

  • How to make a table view which is not the full width of the screen?

    - by mystify
    For some strange reason, UITableView resizes my cells to 320 width no matter how I set the frame for the UITableView object. Even if I go in later and resize the cell back to 250, UITableView seems to resize it again to 320 some time. Is there some property or method that must be set / called additionally to get that right? However, I can add my contents in a way that it looks like 250 width, but my whole layouting code is a big mess since I can't rely on the cell frame width which is "wrong". Also it seems like a big waste of memory since the bitmaps in the layer trees are nonsenseless 320 width instead of 250, even though the frame of the UITableView is not 320 width.

  • UITableViewController setting delegates and datasource

    - by the_great_monkey
    Hi iOS gurus, I'm a little bit confused about UITableViewController... As far as I concern they are typically the delegate and datasource of the UITableView (although it can be made such that they are different). However in some cases, like when embedding a UITableViewController in a UITabBarViewController in Interface Builder, we initiate our table view controller in IB. Therefore in my understanding, the default initialiser is being called. But in this case, I have this piece of code: @interface Settings : UITableViewController { } And in the IB I see that the delegate and datasource of the UITableView is hooked up to this class. My question is, why is it that we don't need to explicitly say that it is following: @interface Settings : UITableViewController <UITableViewDelegate, UITableViewDataSource> { } And in the .m file: - (void)viewDidLoad { [super viewDidLoad]; [tableView setDelegate:self]; [tableView setDataSource:self]; } I have indeed stumbled upon some cases where I have to explicitly code the above a few times to make something work. Although it is still a mystery for me as of why it is needed...

  • UISearchbar issue

    - by hmthur
    I am trying to add a UISearchbar to table header view. I have the icon in nib and have connected the outlets. Now in viewDidLoad, I am writing self.tableView.tableHeaderView = searchbar If i create a local var inside viewDidLoad, it shows up. But not the outlet or ivar one. But for some reason, the UISearchbar does not get displayed in the table. I am not sure what the issue is. Can a UISearchbar not be set in viewDidLoad OR is it something else? Please help.

  • Tracing memory leaks

    - by iFloh
    My favorite candidate again. I am in the process of identifying memory leaks in my app (a puzzling challenge for a newbe like me). I am using the xCode leak analyzer, but what puzzles me is how to trace back a memory leak to its variable or value. Is there a pointer to the instances that have reserved a memory address where a leak is identifyed? How do I best go about it?

  • Tableview not drilling down

    - by JoshD
    I have a Tableview which is loaded with a dummy list of exercises. I need to drill to a different page. My didSelectRow is being called, but not implementing the method. The app is a tab bar navigation app that loads a UITableView. #import <UIKit/UIKit.h> @interface Schedule : UIViewController <UITableViewDelegate, UITableViewDataSource> { NSArray *mySchedule; } @end #import "Schedule.h" #import "AnotherViewController.h" @implementation Schedule - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{ return mySchedule.count; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{ //create a cell UITableViewCell *cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"cell"]; //fill it with contents cell.textLabel.text = [mySchedule objectAtIndex:indexPath.row]; //return it return cell; } - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{ AnotherViewController *anotherViewController = [[AnotherViewController alloc] initWithNibName:@"AnotherViewController" bundle:nil]; [self.navigationController pushViewController:anotherViewController animated:YES]; [anotherViewController release]; } /* // The designated initializer. Override if you create the controller programmatically and want to perform customization that is not appropriate for viewDidLoad. - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) { // Custom initialization } return self; } */ // Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { NSString *myFile = [[NSBundle mainBundle] pathForResource:@"exercise" ofType:@"plist"]; mySchedule = [[NSArray alloc] initWithContentsOfFile:myFile]; [super viewDidLoad]; }

  • Total Size of NSMutableArray object

    - by sj wengi
    Hi Folks, I've got an NSMutableArray that holds a bunch of objects, what I'm trying to figure out is how much memory is the array using. After looking at a couple of places I know about the sizeof call, and when I make it I get 32 bits (which is the size of the NSMutableArray object it self). Example code: NSMutableArray *temp = [[NSMutableArray alloc]init]; [temp addObject:objectxyz]; [temp addObject:objectabc]; [temp addObject:object123]; now I want to know the size :) Thanks, Sj

  • Is it possible to customize @synthesized properties?

    - by Dan K.
    I'm probably just being a bit lazy here, but bear with me. Here's my situation. I have a class with two nonatomic, retained properties. Let's say: @property (nonatomic, retain) UITextField *dateField; @property (nonatomic, retain) NSDate *date; I synthesize them as expected in the implementation. What I want to happen is that whenever the setter on date is invoked, it also does something to the dateField (i.e. it sets the text property on the dateField to be a nicely formatted version of the date). I realize I can just manually override the setter for date in my implementation by doing the following: - (void) setDate:(NSDate *)newDate { if (date != newDate) { [date release]; date = [newDate retain]; // my code to touch the dateField goes here } } What would be awesome is if I could let Objective C handle the retain/release cycle, but still be able to "register" (for lack of a better term) a custom handler that would be invoked after the retain/release/set happens. My guess is that isn't possible. My google-fu didn't come up with any answer to this, though, so I thought I'd ask.

  • Collision detection problems...

    - by thyrgle
    Hi, I have written the following: -(void) checkIfLineCollidesWithAll { float slope = ((160-L1Circle1.position.y)-(160-L1Circle2.position.y))/((240-L1Circle1.position.x)-(240-L1Circle2.position.x)); float b = (160-L1Circle1.position.y) - slope * (240-L1Circle1.position.x); if ((240-L1Sensor1.position.x) < (240-L1Circle1.position.x) && (240-L1Sensor1.position.x) < (240-L1Circle2.position.x) || ((240-L1Sensor1.position.x) > (240-L1Circle1.position.x) && (240-L1Sensor1.position.x) > (240-L1Circle2.position.x))) { [L1Sensor1 setTexture:[[CCTextureCache sharedTextureCache] addImage:@"SensorOk.png"]]; } else if (slope == INFINITY || slope == -INFINITY) { if (L1Circle1.position.y + 16 >= L1Sensor1.position.y || L1Circle1.position.y - 16 <= L1Sensor1.position.y) { [L1Sensor1 setTexture:[[CCTextureCache sharedTextureCache] addImage:@"SensorBad.png"]]; } else { [L1Sensor1 setTexture:[[CCTextureCache sharedTextureCache] addImage:@"SensorOk.png"]]; } } else if (160-L1Sensor1.position.y + 12 >= slope*(240-L1Sensor1.position.x) + b && 160-L1Sensor1.position.y - 12 <= slope*(240-L1Sensor1.position.x) + b) { [L1Sensor1 setTexture:[[CCTextureCache sharedTextureCache] addImage:@"SensorBad.png"]]; } else { [L1Sensor1 setTexture:[[CCTextureCache sharedTextureCache] addImage:@"SensorOk.png"]]; } } Basically what this does is finds m and b in the well known equation: y = mx + b and then substitutes coordinates of the L1Sensor1 (the circle I'm trying to detect if it it intersects with the line segment) to see if y = mx + b hold true. But, there are two problems, first, when slope approaches infinity the range of what the L1Sensor1 should "react" to (it "reacts" by changing its image) becomes smaller. Also, the code that should handle infinity is not working. Thanks for the help in advanced.

  • When does the DENY delete rule in Core Data actually deny deletion of an object?

    - by dontWatchMyProfile
    An Employee has an inverse relationship to it's Department and vice versa. The Employee entity has an Relationship called department, and it has a DENY delete rule. Employee shall be deleted. Now: Does DENY actually deny deletion of employee, because department is still referencing a Department? Or does it mean that a Department can't be deleted because an Employee is referencing it?

  • Pass a class as a parameter?

    - by JuBu1324
    I have been lead to believe that it is possible to pass a class as a method parameter, but I'm having trouble implementing the concept. Right now I have something like: - (id)navControllerFromView:(Class *)viewControllerClass title:(NSString *)title imageName:(NSString *)imageName { viewControllerClass *viewController = [[viewControllerClass alloc] init]; UINavigationController *thisNavController = [[UINavigationController alloc] initWithRootViewController: viewController]; thisNavController.tabBarItem = [[UITabBarItem alloc] initWithTitle: title image: [UIImage imageNamed: imageName] tag: 3]; return thisNavController; } and I call it like this: rootNavController = [ self navControllerFromView:RootViewController title:@"Contact" imageName:@"my_info.png" ]; What's wrong with this picture?

  • How to get multiple copies of a UIView loaded from a nib?

    - by dmaestro12
    I want to use a UIView heirarchy multiple times (the nib object is a template). Unfortunately, UIView does not conform to <NSCopying so [cell.contentView addSubview: [[templEditCellView copy] autorelease]]; does not work. I wasn't surprised, since I want a deep copy of the view heirarchy. Currently the view is a top-level object in the nib it is loaded from. Is there a way to reload a single specified top-level object from the nib? Should I split out the view to a single NIB which can be reloaded on demand? Or is there another way to make a deep copy of a view? Thanks!

JSON connectivity and table are in same class. but how to access this data in another table which is in another view controller. I hope i made my self clear.
