NIB Loads On Simulator But Not On Device?

If something is working on the simulator but not on the device a good starting point for debugging is the filename. The default filesystem on Mac OS is not case-sensitive, but the filesystem on the device is case-sensitive.

Simply, my application's view loads in the simulator, all views intact. When pushed onto the iPhone, the views fail to load. If it makes a difference, my iPhone 4 is jailbroken, but other applications I've created load with no problem on the phone.

If something is working on the simulator but not on the device a good starting point for debugging is the filename. The default filesystem on Mac OS is not case-sensitive, but the filesystem on the device is case-sensitive. So please check if the filename used in your code matches exactly the actual filename.

I've heard this solution before, so I'll leave it here for someone else... But, I ended up reseting my phone using the home and lock buttons, restarted XCode, deleted the application, and then hit "Build and Go". Works now :/ – Matt Egan Nov 5 '10 at 6:49 I guess deleting the application did the trick - maybe you've implemented something that made the data in Documents not compatible anymore and your code started crashing. That's what's happening to me from time to time.

I doubt it was crashing because of loading a NIB. – Michal Nov 5 '10 at 8:58 Scratch that. It's still not working.

- What's super strange is that "viewDidLoad" is still being called... but the views from the view controller aren't loading. I really haven't any idea what could be causing this... *sigh. – Matt Egan Nov 5 '10 at 12:21 Okay.

Simply created a new XIB file, and recreated the same interface. Named it the same as the old file and deleted the old file. - Works now... Who knows... – Matt Egan Nov 5 '10 at 19:20.

What worked for me was what you recommended; delete the app from device (in my case, iPad2), and reboot. Restart Xcode, and now I'm working. I had a very similar issue to you; except, a version of my XIB was loading which was quite old.

Device is properly provisioned, localization is set to what I expected, and yet still an old copy of the XIB was loading. I thought it was my XIB file too... and hated to have to recreate the XIB. I don't know, I guess it was just holding onto something.

My iPhone4 and iPhone3G had no issues.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
