Here’s a script to convert a 1024×1024 png (named “Icon1024.png”) to the required icns file. Save it to a file called “CreateICNS.src” in the folder where your png file is then in terminal “cd” to the same folder and type “source CreateICNS.src” to call it: mkdir MyIcon.iconset sips -z 16 16 Icon1024.png –out MyIcon.iconset/icon_16x16.png sips … Read more
I had the same problem. Brad Larson’s solution worked great even when the view is rotated. Here is his solution translated into code. -(void)setAnchorPoint:(CGPoint)anchorPoint forView:(UIView *)view { CGPoint newPoint = CGPointMake(view.bounds.size.width * anchorPoint.x, view.bounds.size.height * anchorPoint.y); CGPoint oldPoint = CGPointMake(view.bounds.size.width * view.layer.anchorPoint.x, view.bounds.size.height * view.layer.anchorPoint.y); newPoint = CGPointApplyAffineTransform(newPoint, view.transform); oldPoint = CGPointApplyAffineTransform(oldPoint, view.transform); CGPoint position … Read more
stringByTrimmingCharactersInSet only removes characters from the beginning and the end of the string, not the ones in the middle. 1) If you need to remove only a given character (say the space character) from your string, use: [yourString stringByReplacingOccurrencesOfString:@” ” withString:@””] 2) If you really need to remove a set of characters (namely not only … Read more
Updated answer: You can make use of the z and t modifiers to handle NSInteger and NSUInteger without warnings, on all architectures. You want to use %zd for signed, %tu for unsigned, and %tx for hex. This information comes courtesy of Greg Parker. Original answer: The official recommended approach is to use %ld as your … Read more
You can achieve this pretty easily with the help of NSPredicate, like so: NSString *bundleRoot = [[NSBundle mainBundle] bundlePath]; NSFileManager *fm = [NSFileManager defaultManager]; NSArray *dirContents = [fm contentsOfDirectoryAtPath:bundleRoot error:nil]; NSPredicate *fltr = [NSPredicate predicateWithFormat:@”self ENDSWITH ‘.jpg'”]; NSArray *onlyJPGs = [dirContents filteredArrayUsingPredicate:fltr]; If you need to do it with NSURL instead it looks like this: … Read more
According to Apple’s NSInvocation class reference: An NSInvocation is an Objective-C message rendered static, that is, it is an action turned into an object. And, in a little more detail: The concept of messages is central to the objective-c philosophy. Any time you call a method, or access a variable of some object, you are … Read more
Put a try catch around your removeObserver call @try{ [someObject removeObserver:someObserver forKeyPath:somePath]; }@catch(id anException){ //do nothing, obviously it wasn’t attached because an exception was thrown }
Replying to myself: My understanding of the documentation says that using keyword block and setting the variable to nil after using it inside the block should be ok, but it still shows the warning. __block ASIHTTPRequest *request = [[ASIHTTPRequest alloc] initWithURL:… [request setCompletionBlock:^{ NSDictionary *jsonDictionary = [[CJSONDeserializer deserializer] deserialize:request.responseData error:nil]; request = nil; // …. … Read more
Found answer here: NSString *string = @”oop:ack:bork:greeble:ponies”; NSArray *chunks = [string componentsSeparatedByString: @”:”];
setStringValue: is the way to do it. You should make sure your outlet is being set properly. (In the debugger, make sure your textfield variable is not null.)
