)

terminate called after throwing an instance of ‘NSException’

This crash is coming on :[cell.contactImageView setImageWithURL:[NSURL URLWithString:[[contactList objectAtIndex:indexPath.row] objectForKey:PICTURE_KEY]]placeholderImage:[UIImage imageNamed:@"placeholder.png"]];

I am not clear why this crash is happening while running APP on simulator. Any help would be appreciated. Thanx in advance.

Answer 1

I had this problem when running on device too. I forgot to add "-Objc" flag at "Other Linker Flags" settings.

Add Linker Flag

Open the "Build Settings" tab, in the "Linking" section, locate the "Other Linker Flags" setting and add the "-ObjC" flag:
