In my iPhone app I have a settings page where a user can enter text into multiple TextFields. The text fields are all cells within a table. The problem I'm noticing is that when a field scrolls off the phone's screen it loses the value currently in the text field. I notice Apple's apps always have you click on a field to edit it, whic...
I'm just wondering if this is possible (I think not)... The iPhone has a 30 pin connector cable to USB. It "talks" USB already. Is it possible to talk to a MIDI device (i.e. a keyboard with USB) using the cable with the current API? Ideally, one could plug the iPhone directly into the USB port of a MIDI keyboard and then talk to the ke...
NSString *foo = @" x "; NSRange r = [foo rangeOfCharacterFromSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]; NSLog(@"foo range = %d,%d",r.location, r.length); Results in "foo range = 0,1" So will it ever return a length > 1? ...

In discussion with some colleagues we were wondering whether OpenGL work developed for Android or iPhone are effectively interchangeable given that both support the spec. Or is the reality of sharing OpenGL between the two platforms more a case of quirks, tweaks and not as easy as one might have hoped. ...

I also have an instance of this class "A" in the Interface Builder, to connect the class "A" IBOutlet to the corresponding view. So the class "A" is being instanciated t...
I'm making an app where one of the objects needs to appear not to move or rotate during AutoRotation, but everything else needs to rotate and be repositioned. The way I did this is by manually rotating the object, and moving it into the same position, relative to the device, that it had prior to rotation. The problem is that it looks f...

I discovered this: When a UIView's touchesBegan: method is fired and there is only one finger on the screen, the system will wait up to 0.25 seconds to see if the finger move far enough, before it will fire touchesMoved:. There is no programmatically way to get around this problem. But now the interesting part: If one finger is already ...
This may sound like an odd question, but has anyone noticed that their iPhone apps launch quicker when built for distribution over being built for debugging? Our app initially launches really slowly when compiling it for debugging / running it through xcode. (on device) So I then dis-connected the phone from xcode and ran some extremel...
