The line in my code where it starts to crash (with in stack trash #13 above) is

NSString* pStr = [[NSString alloc] initWithUTF8String: pFileName];

For some reason it crashes here. What is odd is that it runs fine in debug mode. But when I make a adhoc build and put it in the iPad through iTunes the above crash occurs.

I have cleaned and rebuilt many tim开发者_如何转开发es, made sure my profiles and identifiers are correct. I have no idea why this may be happening. Any insight or suggestions will help.

Thanks.

Sorry I'm no guru but maybe this will help a little.

This type of crash occurs when Cocoa cannot find the method you are invoking at runtime.

Normally you would receive a warning during compilation.

That said, it seems to be complaining that it cannot find an objective-C selector (method). However, sgLoadFileImage looks to me to be a C function.

For sure, something is different between your debug and release builds. Either the code is different, or the parameters supplied to the methods and functions.
