如何在5秒内显示图形时禁用按钮？

Question

如何禁用从被压一个UIButton ... 而我显示5秒的图形？

self.view.userInteractionEnabled = NO; // if you need the whole view disabled 
    //self.btn.enabled = NO; //if you need button only disabled 

    [UIView animateWithDuration:3.0f animations:^ 
     { 
      // your graphical changes 
      [(UILabel*)addLbl[1] setBackgroundColor:[UIColor redColor]]; 
     } 
    completion:^ (BOOL finished) 
     { 

      self.view.userInteractionEnabled = YES; 
      //self.button.enabled = YES; 
      [(UILabel*)addLbl[1] setBackgroundColor:[UIColor whiteColor]]; 
     } 
    ]; 

Answer 1

可以使用延时方法：

//make your animations and graphical changes.. 
//.... 

self.myButton.enabled = NO; 
[self performSelector:@selector(changeButton) withObject:nil afterDelay:5.0]; //this will happen after 5 seconds 

-(void)changeButton { 
self.myButton.enabled = YES; 
} 

Answer 2

// EDITED。试试这个

self.view.userInteractionEnabled = NO; // if you need the whole view disabled 

[UIView animateWithDuration:3.0f animations:^ { 
    [(UILabel*)addLbl[1] setBackgroundColor:[UIColor redColor]]; 
} completion:^ (BOOL finished) { 
[UIView animateWithDuration:2.0f animations:^ { 
    [(UILabel*)addLbl[1] setBackgroundColor:[UIColor whiteColor]]; 
} completion:^ (BOOL hasFinished) { 
    self.view.userInteractionEnabled = YES; 
}]; 
}];
