iPhone - Crash using addObject on a NSMutableArray

Question

I have a problem here. Or Maybe I\'m really tired...

I have a class :

@interface THECLASS : UIViewController  {
    NSMuta         


        

Answer 1

Your property is defined as retain, and you say that param is "a filled array from the caller view". This could be your problem.

For example, if you do the following:

NSArray * filledArray = [NSArray arrayWithObjects:..., nil];
theClassInstance.param = filledArray;

You will have retained a non-mutable array.

Edit: To debug the setting of param, you could do the following in your .m:

@dynamic param;
- (NSMutableArray*)param { return param; }
- (void)setParam:(NSMutableArray*)newArray {
    NSLog(@"setting new param from class: %@",
          NSStringFromClass([newArray class]));
    [newArray retain];
    [param release];
    param = newArray;
}
