从NSMutableDictionary获取值？

Question

I am getting response from Twitter Response using FHSTwitterEngine.

Code Output

How can I get username and name key values. as I try this

                    self.screenName = [dicUser objectForKey:@"screen_name"];

It gives error.

[__NSArrayM objectForKey:]: unrecognized selector sent to instance 0xcca78b0

Answer 1

You're assuming that the return value is an NSDictionary when in fact it is an NSArray . Protect yourself from crashing by wrapping your call with:

if ([dicUser isKindOfClass:[NSDictionary class]])
{

}
