Hi there! I would like to localize my app but I can't figure how to change text in copy and paste and other other buttons. I tried to google but that is way too much irrelevant info about iphone copy/paste :/ any help is greatly appreciated ...
For my app I need to see if an url is Matched by a regex string. so I created an array with all the regex strings (about 1000+ strings) and check them using RegexKit lite: for (NSString * aString in mainDelegate.whiteListArray) { if (![urlString isMatchedByRegex:aString]) { it works but sadly this operation takes very very long. at l...
Hi, What is the difference between peakPowerForChannel and averagePowerForChannel methods of AVAudioRecorder? And why is the value returned is negative? Isn't it supposed to be 0 for no sound and go up when the amplitude of sound rises? How can I convert to a more "readable" format? Thanks. ...
This has got me stumped. I build an NSArray and initWithObjects. The last element never really allocs. In fact, the next alloc in my code takes the same memory address as the one pointed from the last element. Code is: coordArr = [[NSArray alloc]initWithObjects: [NSValue valueWithCGPoint:CGPointMake(200.0,40.0)], [NSValue va...
Apolgies in advance for any errors.. new to this and am not a developer/programmer.. just have some basic unix experience. I have searched the web and struggled to find a solution to my problem when I stumbled onto this website which maybe suggested that there is a solution to my question. For work i use a windows mobile device because...
I have three buttons set up in Interface Builder, each tied via touchUpInside to btnSelection: - (IBAction)btnSelection:(id)sender { NSLog(@"tag: %i", [sender tag]); } In my console, the first click registers correctly (after a second or so delay, which seems a bit weird) but any subsequent touch of any of the 3 buttons results in...
Is it possible to do pixel perfect collision in a view based application ? I've been looking for example codes but with no luck... Also can you use colored bitmaps to represent collision for a certain color ? ...
Hello, Does anybody know a sample application which helps and show how to add a gradient color to an iPhone application. ...
I have a database model class that is a NSObject. I have a set of these objects in a NSMutableArray. I use indexOfObject: to find a match. Problem is the model object's memory address changes. So I am overriding the hash method to return the model's row ID. This however does not fix it. I also have to override the isEqual: method to comp...
I have a UISegmentedControl which I'd like to use to perform a certain action if you click the already selected item. My thinking is basically something like this: - (void)viewDidLoad { UISegmentedControl * testButton = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:@"one", @"two", nil]]; [self.view addSubv...
Total nooob here. I'm trying to figure out how to implement a transition from one UIWebview to another with a swipe and still be able to scroll/zoom w/in each webview. Each webview should respond normally to all touches/gestures unless a swipe is detected and the boundry of the view/content is at the corresponding edge of the screen...
When the user touches into an UIScrollView and wants to scroll, there is a little delay. UIKit tries to find out if the user wanted to touch the content in the scroll view or if the user wanted to scroll. So it waits a moment if the finger moves far enough, and then starts scrolling. Could I tell it that it must start scrolling with no d...
I am using navigation with a custom UIView subclass that becomes my titleView. I want to ensure this is the full available width. Logically from my UIViewController's viewWillAppear:, this should be: CGFloat width = self.width - self.navigationItem.leftBarButtonItem.width - someConstant; (I don't have a right item here.) This would ...
Maybe this can solve out the ugly delay with touchesBegan: to touchesMoved:. It is caused artifically by iPhone OS to check if the user really wants to move. In some situations the finger must be tracked without delay, otherwise it just looks ugly. You see that everywhere through iPhone OS. Sliders, Scroll Views. Maybe accelerating the ...
It works fine on every subsequent launches. I'm using an OpenGL animation at the start, if it matters. ...
imgBiteSpot.clipsToBounds=YES; NSData *imageData = [[[NSData alloc]init]autorelease]; imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:ObjBitSpot.StrImagePath]]; if(imageData==0) { imgBiteSpot.image=[UIImage imageNamed:@"img-not-found.gif"]; } else { UIImage *imgs = [[UIImage alloc] initWi...
I found this little text on the net: UIScrollView overrides hitTest method and always returns itself, so that all touch events (touchesBegan, touchesMoved, touchesEnded, touchesCancelled) go into it. Then inside touchesBegan, touchesMoved etc it checks if it's interested in the event, and either handles or passes it o...

Hi, I have extended both NSString and NSMutableString with some convenience methods using categories. These added methods have the same name, but have different implementations. For e.g., I have implemented the ruby "strip" function that removes space characters at the endpoints for both but for NSString it returns a new string, and fo...
