libc++abi.dylib: terminating with uncaught exception of type NSException
And the property in question is
#property(strong,nonatomic) NSURL *imageURL;
with setter
-(void)setImageURL:(NSURL *)imageURL
{
_imageURL=imageURL;
[self startDownloadingImage];
}
The strange thing is this used to work and about an hour or so ago it stops working and starts throwing this exception.
update
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
BCDDogImageTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:[BCDDogImageTableViewCell cellPrototypeIdentifier] forIndexPath:indexPath];
NSLog(#"THE CELL IS: %# ", cell);
cell.imageURL=[NSURL URLWithString:self.imageURLs[indexPath.row]];
return cell;
}

Answer 1

The error is because your cell is actually a UITableViewCell instance and not an instance of your custom cell class.
Be sure to register your custom cell class for the cell.
