• UIControlEventTouchDragExit only fires ~100 pixels out

  - by Jonathan

  Im trying to "get" when a finger/touch leaves a UIButton in objective C for iphone. I was told in another answer to use UIControlEventTouchDragExit however this event only fires when the touch gets about 100 pixels away from the button, whereas I would like it to be immediate. The apple docs say that goes according to the bounds however my understand is the bounds and the frame are the same unless you rotate the UIbutton (or whatever)

• What is happening to NCurses and OS X 10.6?

  - by John Velman

  Apparently libncurses...dylib is broken OS X 10.6.3 relative to Mutt, and perhaps other applications, that use ncurses, although it works in 10.6 (as I can attest) and reportedly it works in 10.6.2. Does anyone know if this is a bug or a feature in the view of Apple? If a feature, is there a workaround for people who want to upgrade 10.6..., but also want to use, for example, Mutt? Thanks

• Older iPhone/ iPod frame rate?

  - by Adam

  Do older iPods and iPhones have a frame rate of 60fps? I'm finding that all the methods for calculating time intervals on iPhone (cftimeinterval, nstimer, timesince1970, etc) are all giving me bad data, so I've decided assume a frame rate of 60, just not sure if older apple devices can run at this.

• Object allocate and init in Objective C

  - by Ronnie Liew

  What is the difference between the following 2 ways to allocate and init an object? AController *tempAController = [[AController alloc] init]; self.aController = tempAController; [tempAController release]; and self.aController= [[AController alloc] init]; Most of the apple example use the first method. Why would you allocate, init and object and then release immediately?

• UITableView hide sectionindex but retain sections

  - by Dan Bennett

  We'd like to implement our own section index UI for UITableView. It's clearly possible, since the contacts app does it on iPad. Is there a way of legally hiding the current section index? (I can get to the undocumented _index UIView but that's not going to cut it with Apple I suspect)

• AVCam memory low warning

  - by Red Nightingale

  This is less a question and more a record of what I've found around the AVCam sample code provided by Apple for iOS4 and 5 camera manipulation. The symptoms of the problem for me were that my app would crash on launching the AVCamViewController after taking around 5-10 photos. I ran the app through the memory leak profiler and there were no apparent leaks but on inspection with the Activity Monitor I discovered that something called mediaserverd was increasing by 17Mb every time the camera was launched and when it reached ~100Mb the app crashed with multiple low memory warnings.

• Custom UINavigationBar Background

  I've been trying to set up a custom background for the whole of my NavigationBar (not just the titleView) but have been struggling. I found this thread http://discussions.apple.com/thread.jspa?threadID=1649012&tstart=0 But am not sure how to implement the code snippet that is given. Is the code implemented as a new class? Also where do I instatiate the NavigationController as I have an application built with the NavigationView template so it is not done in my root controller as per the example
