You need NSTimer and you need to invoke a method something as :

*This is for OSX, you can easily convert it into iOS, NSTextField and UILabel has different methods.

-(void)awakeFromNib{     self.myTimer=[NSTimer new];     self.fullString=@"This is a long string to be shown.";     [self.label setAlignment:NSRightTextAlignment]; }   -(void)scrollText:(id)parameter{     static NSInteger len;     [self.label setStringValue:[self.fullString substringWithRange:NSMakeRange(0, len++)]];      if (self.label.stringValue.length==self.fullString.length) {         [self.myTimer invalidate];     } }  - (IBAction)buttonAction:(id)sender {      self.myTimer = [NSTimer scheduledTimerWithTimeInterval:0.2f                                                     target: self                                                   selector:@selector(scrollText:)                                                   userInfo: nil                                                     repeats:YES]; }
