Random text to fade -

how random text fade, text1 text2?

my code follows:

 -(ibaction)generatenumbers; {     int randomnumber = arc4random() % 1;     switch (randomnumber) {         case 0:             label.text = @"text1";             break;         case 1:             label.text = @"text2";             break;         default:             break;      } } 

-(ibaction)generatenumbers; { int randomnumber = arc4random() % 2; switch (randomnumber) { case 0:     label.text = @"text1";     break; case 1:     label.text = @"text2";     break; default:     break;  } } 

for fadein/out use methods

- (void) settextwithfade {    [label setalpha:1];    [uiview beginanimations:nil context:nil];    [uiview setanimationduration:1];    [uiview setanimationdelegate:self];    [uiview setanimationdidstopselector:@selector(fadedidstop)];    [lbl setalpha:0];    [uiview commitanimations]; }  - (void)fadedidstop {    label.text = @"new text";    [uiview beginanimations:nil context:null];    [uiview setanimationduration:1];    [lbl setalpha:1];    [uiview commitanimations]; } 

call first method when click button this:

 [self settextwithfade];
