  • How to dismiss the MFMailComposeViewController in cocos2d ?

    - by srikanth rongali
    I have changed my code to this way. Now mail controller is opening in landscape mode. But the problem is If I touch on cancel button or send button the mail controller is not dismissing its view. How can I do it ? -(void)goToFirstScreen:(id)sender { NSLog(@"goToFirstScreen: "); CCScene *Scene = [CCScene node]; CCLayer *Layer = [EmailScene node]; [Scene addChild:Layer]; [[CCDirector sharedDirector] setAnimationInterval:1.0/60]; [[CCDirector sharedDirector] pushScene: Scene]; } Th EmailScene class is #import "EmailScene.h" #import "testOfEnd.h" @implementation EmailScene - (id) init { self = [super init]; if (self != nil) { [self displayComposerSheet]; } return self; } -(void)displayComposerSheet { [[CCDirector sharedDirector] pause]; picker = [[MFMailComposeViewController alloc] init]; picker.mailComposeDelegate = self; [[[CCDirector sharedDirector] openGLView] addSubview:picker.view]; [[CCDirector sharedDirector] stopAnimation]; [picker presentModalViewController:picker animated:YES]; [picker release]; } - (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error { [[CCDirector sharedDirector] resume]; //dismiss view after otherwise the code is not executed [picker.view removeFromSuperview]; [[CCDirector sharedDirector] startAnimation]; [picker dismissModalViewControllerAnimated:YES]; //return to previous scene CCScene *Scene = [CCScene node]; CCLayer *Layer = [testOfEnd node]; [Scene addChild:Layer]; [[CCDirector sharedDirector] replaceScene:Scene]; } @end Thank You.

  • mouseover detection in NSTableView's NSCell?

    - by Wigwam
    I am wanting to change the text background color on a tableview's cell when it is hovered upon, similar to how AddressBook "highlights" the label of a contact's element when you mouseover the label names. However I cannot figure out how to accomplish... detecting a mouseover on a particular NSCell and... After detecting the cell his hovered upon, highlighting the text in that cell (not highlighting the entire row as if the user selected that row) As NSCell is not a subclass of NSView this seems to be a very difficult task. Any example of this or explanation on how this might be done would be greatly appreciated. Thanks!

  • Custom UILabel does not show text.

    - by Oscar
    Hi! I've made an custom UILabel class in which i draw a red line at the bottom of the frame. The red line is showing but i cant get the text to show. #import <UIKit/UIKit.h> @interface LetterLabel : UILabel { } @end #import "LetterLabel.h" @implementation LetterLabel - (id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame:frame]) { // Initialization code } return self; } - (void)drawRect:(CGRect)rect { CGContextSetLineWidth(UIGraphicsGetCurrentContext(), 2.0); CGContextSetRGBStrokeColor(UIGraphicsGetCurrentContext(), 1.0, 0.0, 0.0, 1.0); CGContextBeginPath(UIGraphicsGetCurrentContext()); CGContextMoveToPoint(UIGraphicsGetCurrentContext(), 0.0, self.frame.size.height); CGContextAddLineToPoint(UIGraphicsGetCurrentContext(), self.frame.size.width, self.frame.size.height); CGContextStrokePath(UIGraphicsGetCurrentContext()); } - (void)dealloc { [super dealloc]; } @end #import <UIKit/UIKit.h> #import "Word.h" @interface WordView : UIView { Word *gameWord; } @property (nonatomic, retain) Word *gameWord; @end @implementation WordView @synthesize gameWord; - (id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame:frame]) { self.backgroundColor = [UIColor whiteColor]; LetterLabel *label = [[LetterLabel alloc] initWithFrame:CGRectMake(0, 0, 20, 30)]; label.backgroundColor = [UIColor cyanColor]; label.textAlignment = UITextAlignmentCenter; label.textColor = [UIColor blackColor]; [label setText:@"t"]; [self addSubview:label]; } return self; } - (void)drawRect:(CGRect)rect { // Drawing code } - (void)dealloc { [gameWord release]; [super dealloc]; } @end

  • How do I enable spell checking within an NSTextField on Mac OS X?

    - by Luke
    I have an NSTextField that I would like to enable "as-you-type" spell checking. When I load my application I can do this from the Menu Bar Edit Spelling and Grammar Check Spelling While Typing. I would like this option to be enabled by default. Within IB I can enable this for a NSTextView but I would like to use NSTextField for this part of the UI. Thank you.

  • iPhone/iPad : Check for invalid characters in a textbox made for Integers only

    - by JustinXXVII
    I noticed that the iPhone OS is pretty good about picking out Integer values when asked to. Specifically, if you use NSString *stringName = @"6("; int number = [stringName intValue]; the iPhone OS will pick out the 6 and turn the variable number into 6. However, in more complex mistypes, this also makes the int variable 6: NSString *stringName = @"6(5"; int number = [stringName intValue]; The iPhone OS misses the other digit, when what could have possibly been the user trying to enter the number 65, the OS only gets the number 6 out of it. I need a solution to check a string for invalid characters and return NO if there is anything other than an unsigned integer in a textbox. This is for iPad, and currently there is no numeric keyboard like the iPhone has, and I'm instead limited to the standard 123 keyboard. I was thinking that I need to use NSRange and somehow loop through the entire string in the textbox, and checking to see if the current character in the iteration is a number. I'm lost as far as that goes. I can think of testing it against zero, but zero is a valid integer. Can anyone help?

  • How to get the current eventNumber for creating an event with NSEvent

    - by Chris
    Hello I'm creating an os x application for which I try to add a remote interface. For this I need to be able to send mouse down and mouse up commands to the window of my application. I found code with which I can successfully do this, it looks as follows: int mask = 0x100; NSEvent* eventMouseDown = [NSEvent mouseEventWithType:NSLeftMouseDown location:p modifierFlags:mask timestamp:[NSDate timeIntervalSinceSystemStartup] windowNumber:[w windowNumber] context:[NSGraphicsContext graphicsContextWithWindow:w] eventNumber:++eventCounter +42599 clickCount:1 pressure:0]; NSLog(@"Mouse down event: %@", eventMouseDown); [[NSApplication sharedApplication] sendEvent:eventMouseDown]; I have only one problem with this code thought and this is the eventNumer parameter. As far as I found out it is a number which get increased with each event. But I cannot find a way to find the current number from where on I need to increase. The number I use there currently is just try and error and also does not seam to work always.

Now I want tu filter the array using NSPredicate predicate = [NSPredicate predicateWithFormat:[NSString stringWithFormat:@"(engine like %@)", searchText]]; newArray = [ArrayWithCars filteredArrayUsingPredicate:predicate]; This throws an valueForUndefinedKey error. Is the predicateWithFormat correct? thanks for your responses

  • How to add a TabBar to NavigationController based iPhone app

    - by Alex
    I have a simple NavigationController based app. The main window shows a TableView and selecting an item loads a sub-view. I used Interface Builder for UI views. Now I want to add a TabBar to the app. Where do I put it? Do I need a TabBarController? Should it go in the MainWindow.xib, or RootViewController.xib? How do I tie it together with my NavigationController?

  • Prevent status bar from receiving touch events

    - by Typeoneerror
    Edit After further testing, it appears that the part of my button that are not clickable are where the status bar used to be. I'm hiding the status bar with : // -- Override point for customization after app launch [[UIApplication sharedApplication] setStatusBarHidden:YES]; But it's still receiving touches. Any idea on how to disable this? Is there's a bounding box on an application that receives touch events? I created a few sample round rect buttons and placed them in different places in my view. The ones in the center of the view receive touch events (and show the highlighted blue color) but if I place a button near the edges of the view, only parts of them are clickable in the simulator. Is this because of Apples style guidelines? I placed a button exactly where a UITabNavigationItem would appear and only the bottom half of it is clickable.

  • Bug in XCode debugger?

    - by John Smith
    I am working on an iPhone app which is using an external library for which I have the source. During debugging some of the objects are listed as 0x0 in the debugger but the app runs fine. Also, some of the objects addresses point to the wrong thing. These symbols are in the external library. The addresses are fine if I am tracing through a file actually in the external library. Does anyone have suggestions how to stop this behavior?

  • How can I fix this clang warning: "Object with +0 retain counts returned to caller where +1 (owning)

    - by mipadi
    I have a piece of Objective-C code that looks like the following: - (NSString *)copyData:(NSData *)data { NSString *path = [[[self outputDirectory] stringByAppendingPathComponent:@"archive"] stringByAppendingPathExtension:@"zip"]; NSLog(@"Copying data to %@", path); [data writeToFile:path atomically:NO]; return path; } The code is called from an initializer that looks like this: - (id)initWithData:(NSData *)data { if ((self = [super init]) != nil) { NSString *path = [self copyData:data]; // Line 41 (referenced in warning, shown below) return [self initWithContentsOfFile:path]; } return self; } When running the clang static analyzer, I get the following warnings for the path variable: Potential leak of an object allocated on line 41 and stored into 'path' Object with +0 retain counts returned to caller where +1 (owning) retain count is expected I'm confused. My understanding is that stringByAppendingPathComponent should not return an autoreleased string, so it should have a net retain count of 0. (Obviously I don't want to retain it.) I've tried altering copyData: to return the following, but it didn't get rid of the warning: return [[path retain] autorelease]; So what's the deal with this warning?

  • Objective C - Constants with behaviour

    - by Akshay
    Hi, I'm new to Objective C. I am trying to define Constants which have behavior associated with them. So far I have done - @interface Direction : NSObject { NSString *displayName; } -(id)initWithDisplayName:(NSString *)aName; -(id)left; // returns West when North -(id)right; // return East when North @end @implementation Direction -(id)initWithDisplayName:(NSString *)aName { if(self = [super init]) { displayName = aName; } return self; } -(id)left {}; -(id)right {}; @end Direction* North = [Direction initWithDisplayName:@"North"]; // error - initializer element is not constant. This approach results in the indicated error. Is there a better way of doing this in Objective C.

  • Checking if a touch is withing a UIButton's bounds.

    - by Joshua
    I am trying to make an if statement which will check whether the users touch is within a UIButton's bounds. I thought this would be an easy affair as UIButton is a subclass of UIView, however my code doesn't seem to work. This is the code I have been using. - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { NSArray *array = [touches allObjects]; UITouch *specificTouch = [array objectAtIndex:0]; currentTouch = [specificTouch locationInView:self.view]; if (CGRectContainsPoint(but.bounds, currentTouch)) { //Do something is in bounds. } //Else do nothing. }

  • Simple NSTableView bindings example

    - by sirjorj
    I am trying to populate a 2-column NSVTableView via bindings, but the data is not showing up in the table. In XCode: I have a NSMutableArray in my AppDelegate that will hold the data, as well as the corresponding @property and @synthesize. On an event, I call [removeAllObjects] on the NSMutableArray and repopulate it with some NSDictionary objects. Each dictionary contains 2 KVP's: a NAME and a VALUE. In IB: I added an NSArrayController and bound it's Content Array to my AppDelegate and set the ModelKeyPath to the name of the NSMutableArray in the AppDelegate. On the NSTableView, I bound the Content to the ArrayController. ControllerKey = "arrangedObjects", ModelKeyPath = empty. For each of the two columns, I bound the Value to the AppController and set the ModelKeyPaths to NAME and VALUE respectively. ControllerKey = "ArrangedObjects". I have tried several other things, such as using an NSArray in the app delegate and making a new one every time I need to update the values. There must be some tiny little thing I am forgetting. What is it? jorj

  • Why Doesn't UIWebView release all of its memory?

    - by Theory
    I have a graphic-intensive iPad app that features a UIWebView. Using the simulator (iOS 4.2.1), I can see Real Mem increase quite a lot as I browse. The more I browse, the more RAM it uses. When I close the UIWebView and release it, some of the memory it used is freed, but not all of it. This is annoying. Okay, so maybe it's because it isn't deallocated right away. Fine. But then I would expect the system to do some cleanup when there's a memory warning. However, if I browse around, then close the UIWebView (and release it), then trigger a memory warning in the simulator, Real Mem does not change! WTF? So why is this? Why isn't UIWebView better at releasing memory back to the system? And why doesn't it appear to respond to memory warnings? Am I missing something?

  • iPhone dev: Recurse all project resoureces and collect paths

    - by thomax
    I have a bunch of HTML resources in my app organized in a hierarchy like so: dirA |---> index.html |---> a1.html |---> a2.html |---> dirB |---> b1.html |---> b2.html |---> dirC |---> c5.html |---> c19.html I'm trying to collect the absolute paths of all HTML resources however deep down, but can't seem to figure out how. So far I've tried: NSArray myPaths = [[NSBundle mainBundle] pathsForResourcesOfType:@"html" inDirectory:nil]; This returns an empty array, because I have no HTML files at the root of my project. Then there is: NSArray myPaths = [[NSBundle mainBundle] pathsForResourcesOfType:@"html" inDirectory:@"dirA"]; This returns an array containing only the paths for the three HTML resources directly below dirA. If I read the doc correctly, I guess this is to be expected; pathsForResourcesOfType does not traverse subdirectories. But is there a (preferably nice) way to do it?

  • Problems with NSTask in OS X 10.6 Snow Leopard

    - by kubi
    Has anyone else seen or heard of any issues with NSTask in 10.6? This code worked fine yesterday, and is not working today. NSTask *task = [converter task]; [task waitUntilExit]; NSLog(@"Task did complete"); The task does what it's supposed to do (I checked the output and it's fine), but the program will wait indefinitely at the waitUntilExit method. I have a few unit tests that use similar code, they all had passed previously, but as of yesterday, they are no longer working.
