I got nabbed by the following bug again and would like some clarification to exactly why it is a bug.
I have a simple UITableView that loads some data:
// myclass.h
@property (nonatomic, retain) NSArray *myData
// myclass.m
@synthesize myData;
- (void) viewDidLoad {
...
myData = someDataSource // note the lack of self
}
- (UITableViewCell *) cellForRowAtIndexPath ... {
...
cell.textLabel.text = [self.myData objectAtIndex:indexPath.row]; // EXC_BAD_ACCESS
}
The table first loads fine, but when scrolling up enough that one of the cells is totally out of the view I then get the EXC_BAD_ACCESS error.
Am I missing something in regards to @property retain. My understanding is that it releases anything that the pointer was previously pointing to before the reassignment. If I am correct then why would not using self. cause any problems?
Thanks for the help.
