iOS: Why can not I set nil to NSDictionary?
advertisements
This might be very basic question but I was wondering why can't I assign nil as NSDictionary value? I have following statement many places in my code. If [q objectForKey:@"text"] is nil then App is crashing.
NSMutableDictionary *dict = [[NSMutableDictionary alloc] initWithCapacity:2];
[dict setObject:[q objectForKey:@"text"] forKey:@"text"];
I have to check everywhere for the nil before assigning it to dictionary. Is this the only correct way of doing? Am I missing something obvious?
if([q objectForKey:@"text"] != nil)
[dict setObject:[q objectForKey:@"text"] forKey:@"text"];
else
[dict setObject:@"" forKey:@"text"];
It wants an actual object... use NSNull
