ios - 在iOS中按住一个按钮应该显示按钮的标题

Question

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

Answer 1

试试这个，也许它会帮助你...

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

Answer 2

用这个：

-(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

只需为 UIControlStateHighlighted 设置标题...而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];
