uilabel *label; - (void)viewdidload {     [super viewdidload];      label = [[uilabel alloc]initwithframe:cgrectmake(10, 50, 300, 20)];     label.font = [uifont fontwithname:@"courier-bold" size:16.0];     label.backgroundcolor = [uicolor blackcolor];     label.textcolor = [uicolor greencolor];     label.linebreakmode = uilinebreakmodecharacterwrap; // otherwise "…"     label.text = @"this led text scrolled               "; // blanks space between     [self.view addsubview:label];      [nstimer scheduledtimerwithtimeinterval:0.12f target:self                                     selector:@selector(scrolllabel)                                     userinfo:nil repeats:yes];  }  - (void)scrolllabel {     label.text = [nsstring stringwithformat:@"%@%@", [label.text substringfromindex:1], [label.text substringtoindex:1]]; }
