Question:
I want to add string to message of my UIAlertView
-(void) errorState:(NSException *) exp { NSLog(@"Error State Blood Level3 %@",exp); NSString * myString = (NSString*)exp; UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" message:myString delegate:self cancelButtonTitle:@"Go to the main menu" otherButtonTitles:nil]; [alert show]; [alert release]; }
2010-07-15 12:48:34.721 kndFrameV02[7955:207] -[NSException isEqualToString:]: unrecognized selector sent to instance 0x707b2e0 2010-07-15 12:48:34.724 kndFrameV02[7955:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSException isEqualToString:]: unrecognized selector sent to instance 0x707b2e0' so how can i add string variable to the message of UIAlertView?
Solution:1
An NSException won't suddenly turn into an NSString when you cast it as one. NSException has a property called reason, that's the one you need. Use it like this: NSString *reason = exp.reason;
