When I programmatically allocated a UILabel in my custom initWithNibName method, and later in viewDidLoad, tried to assign a string to it, the label was not pointing to anything. I didn't release it; the label shows on the screen. If I create the label in IB, and assign text to it in viewDidLoad, it works. Is it against a rule to set up...
During my performance tests I found out the the SQLite version which Apple provides on the iPhone 3.0 is significantly faster then my self compiled amalgamation SQLite version. So my question is, is there a way to find out which compilation options Apple did use? Is there a test app which prints out all the default set pragams and sqlit...
Can I do a search of the iPhone filesystem from within an application? I need to search an iPhone OS device and return a list of all apps installed on an iPhone OS device. I am fairly aware of Apple's restrictions and rules concerning what apps can and mostly cannot do outside of the sandbox -- and know that aside from the Photo Album an...
Hi I am using multiple UIAlertViews in my code as follows -(void) myfunc { myAlertView1 = [[UIAlertView alloc] initWithTitle:@"Message" message:[list objectAtIndex:1] delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil]; [myAlertView1 show]; [myAlertView1 release], myAlertView1 = nil; { do something ...
I've tried this, but that doesn't work: CATransform3D currentTransform = self.layer.transform; CATransform3D identityTransform = CATransform3DIdentity; if (currentTransform == identityTransform) NSLog(@"the same"); I really woulnd like to compare each single field in the matrix ;) Can I instad compare that somehow as a whole big thin...
There seems to be an delegate that can be set like myView.layer.delegate = anObject The documentation just says: delegate Specifies the receiver’s delegate object. @property(assign) id delegate I wonder what kind of methods that delegate would implement, and when they would be called. Could solve some big problems ...

My delegate for ended animations looks like this: (void)animationDidEnd:(NSString *)animationID finished:(BOOL)finished context:(void *)context for some reason, the finished is always NO in my animation chain. But I need to know if an animation in my chain has finished completely. Example: Something says: "move to (20,100)". And as ...
So I have started building plist files using NSCoder, but as I"m developing i want to look at them and see what data is being saved. How do i find/access the plist files generated by my app in the simulator (and on the device when i get to that) Places Ive looked: application bundle build directory ...
As a result of the search for an answer of this question, I ran into a rather uncomfortable finding. It seems that rendering only glClearColor() at 60 fps pushes the iPhone at 27% render utilization. That means that doing hardly anything at all - only refreshing the screen - makes the iPhone use more than a quarter of its render capaci...
I have a model of a snowman that I am loading from a .obj file. Everything works well except that when I use glRotatef() to rotate the model the head of the snowman will always render in front of the body. The nose of the snowman will also always render behind the head. This creates the effect that the snowman changes direction as he is ...
There is a function like: CATransform3DGetAffineTransform Returns the affine transform represented by 't'. If 't' can not be exactly represented as an affine transform the returned value is undefined. I'm not so math-orientated, so a easy to understand description would be very nice. Wikipedia was no big help here. ...

And i would like the instance variable (which is being passed into the method) to now reference the new value assi...
Hi, I'm trying to use the audioplayer with a slider in order to seek into a track (nothing complicated). But I have a weird behavior... for some value of currentTime (between 0 and trackDuration), the player stop playing the track, and goes into "audioPlayerDidFinishPlaying:successfully:" with successfully to NO. And it did not go into ...
I've a iPhone App that relies heavily of TableViews and SQLite database. Where do you store the data? In my case I pull data from the web in App Delegate and store it in AppDelegate and save it to DB at regular intervals. The rootviewcontroller is a tableview that reads the appdelegate object and populates itself. But, according to Eva...

We use encrypted web pages in our iPhone app, and intercepts these calls (e.g. when clicking a link) in the webView:shouldStartLoadWithRequest: method to get the file path, decrypt the data to the original html string and then doing a loadHTMLString: on the webView (returning YES in webView:shouldStartLoadWithRequest:, obviously). The p...
