Question

I would like to do this:
I have a dictionary like this:

[myMutableDictionary setValue:myNSNumber forKey:@"myKey"];

myNSNumber is an NSNumber.

myCell.label.text = [self.myMutableDictionary objectForkey@"myKey"];

I have an error when I assign the number stored in my dictionary to my label in myCell.
The error is:

je suis la 2011-05-02 15:01:01.264 []
-[NSCFNumber isEqualToString:]: unrecognized selector sent to instance
0x225d00 2011-05-02 15:01:01.319 []
*** Terminating app due to uncaught exception
‘NSInvalidArgumentException’, reason:
‘-[NSCFNumber isEqualToString:]:

0x225d00’

Answer 1

NSNumber is not an NSString and the text of the label needs to set to an NSString.

NSNumber *num = (NSNumber*)[self.myMutableDictionnary objectForkey@"myKey"];
myCell.label.text = [num stringValue];
