Question

I am having an issue for the following method in my AppDelegate.

- (void)itemDiscovered:(PodcastShow *)show
{
    NSLog(@"%@", show);
    NSArray* newArray = [self.showArray arrayByAddingObject:show];
    self.showArray = (NSMutableArray*)newArray; //This line signals SIGABRT
}

I’m a fairly new with ARC and Objective-C in general. Obviously, there is a memory issue, but I don’t know what I’m doing wrong. I’ve written a ton of code just like this and I’ve never come across an issue like this. Here is the showArray property:

@property (strong, nonatomic) NSMutableArray *showArray;

Any help would be greatly appreciated.

Answer 1

Try [self.showArray addObjectsFromArray:newArray] or [self.showArray addObject:show].

Also be sure that you are creating the mutable array by calling self.showArray = [NSMutableArray array] (or something similar) somewhere in your code.
