Custom UIButton in UIscrollview

Question

I am using xcode 4.6 to develop an app. Here i want to add UIButton programmatically to UIscrollview. This is the code i follow.

UIButton *bt =[[UIButton alloc]initWithFrame:frame];
bt=[UIButton buttonWithType:UIButtonTypeCustom];
[bt setTitle:@"Custom Button" forState:UIControlStateNormal];
[bt addTarget:self action:@selector(userTappedOnLink:) forControlEvents:UIControlEventTouchUpInside];
bt.backgroundColor = [UIColor grayColor];
bt.titleLabel.textColor=[UIColor blueColor];
[self.mainscrollview addSubview:bt];
[self.mainscrollview bringSubviewToFront:bt];

Now the problem is that Button gets disappeared (technically its textcolor becomes white) on click. I checked keeping UIscrollview color to red that th button was still in the view but i cant get the reason why its text color changed and how do i undo dis. Basically I wan to create a clickable link using UIbutton. I know uitextview approach (datadetectortype) but its of no use as i want to show different text in the label for the link and the actual link.

Note: The textcolor doesnt change back to blue and remains white only.

Thanks in advance.

Try the below code

UIButton *bt =[UIButton buttonWithType:UIButtonTypeCustom];
bt.frame = CGRectMake(50.0, 50.0, 100.0, 50.0);
[bt setTitle:@"Custom Button" forState:UIControlStateNormal];
[bt addTarget:self action:@selector(userTappedOnLink:) forControlEvents:UIControlEventTouchUpInside];
bt.backgroundColor = [UIColor grayColor];
bt.titleLabel.textColor=[UIColor blueColor];
[self.scrollTest addSubview:bt];

-(void)userTappedOnLink:(UIButton*)sender
{
     NSLog(@"Test  ..");

    [self performSelector:@selector(changeBtnTextColor:) withObject:sender afterDelay:1.0];
}

-(void)changeBtnTextColor:(UIButton*)btn
{
  btn.titleLabel.textColor=[UIColor blueColor];
}

hope it will work for you.
