按住iOS中的按钮应显示按钮的标题

Question

正如问题的标题所述，当我按住iOS中的按钮时，我希望按钮的标题出现。我该怎么做？需要一些建议..

Answer 1

试试这个，可能会帮助你......

[btnName setTitle:@"Your Title" forState:UIControlStateHighlighted];

Answer 2

使用此：

-(IBAction)BtnTouchdown:(id)sender
{
    mytimer = [NSTimer scheduledTimerWithTimeInterval:3.0 target:self selector:@selector(showBtnTitle) userInfo:nil repeats:NO];                
}

-(void)showBtnTitle
{
   //use label to show title
}

Answer 3

只为UIControlStateHighlighted设置标题......对于其他状态，应该没有标题......

[btnName setTitle:@"Title" forState:UIControlStateHighlighted];

[btnName setTitle:@"" forState:UIControlStateNormal];

[btnName setTitle:@"" forState:UIControlStateSelected];
