Simple string concatenation in Objective C
This code here is working for me
NSString *s = @"avant";s = [s stringByAppendingString:@" - après"];NSLog(@"%@", s);2012-01-13 11:48:59.442 tabbar[604:207] avant - après
So my guess is that your you is a bad pointer that is not nil and not the NSString you think it have.
Have you try an NSLog on that value before the call?
You can try this also:
you = [NSString stringWithFormat:@"%@%@", you, @"123"];
Code :
NSString *you;you = @"This is you String!";NSLog(@"you : %@ ",you);you = [you stringByAppendingString:@"123"]; NSLog(@"you : %@ ",you);[you stringByAppendingFormat:@"%@%@",you,@"123"];NSLog(@"you : %@ ",you);Result in Console :
[233:907] you : This is you String!
[233:907] you : This is you String!123
[233:907] you : This is you String!123
