Bad_ACCESS错误，我不太了解

Question

i get a bad_access error when i try to run my program, normally i can figure this stuff out but when i get the error it jumps me to this line of code.

int retVal = UIApplicationMain(argc, argv, nil, nil);

I did not write whats above, but when i remove the following program runs fine...

NSLog(@"Store Data Count : %i", [storedData count]);
if ([storedData count] < 4) {

It was working before, and storedData is an NSMutableDictionary. I dunno if thats enough info, but if anyone could let me know what going on that would be really awesome. Thanks!

Answer 1

This means you've messed up your memory management and either over-released an object or sent a message to an object that's been released. Turn on NSZombieEnabled and you'll probably find out where very quickly.

Answer 2

如果要在使用storeData的方法之外创建storeData ，请确保在使用它之前保留了storedData ，并且不会在任何地方释放它。
