Question

我到处搜索试图找到答案，但我发现的任何答案都不适合我...... 我想在按下时更随机地制作一个按钮。我知道这很简单，xcode没有解决任何问题。当我运行我的代码时，模拟器运行正常，除了按钮不移动的事实。这是我使用的代码;

-(IBAction)Counter {
[self moveButton];

}

-(void)moveButton {
int xCo = arc4random() %200;
int yCo = arc4random() %200;
CGRect frame = Butoon2.frame;
frame.origin.x = xCo;
frame.origin.y = yCo;

[UIView beginAnimations:nil context:nil];

[UIView setAnimationDuration:0.001];
Butoon2.frame = frame;
[UIView commitAnimations];

}

非常感谢您的投入！

Answer 1

试试这个：

-(void)moveButton {
int xCo = arc4random() %200;
int yCo = arc4random() %200;
CGRect frame = Butoon2.frame;
frame.origin.x = xCo;
frame.origin.y = yCo;

[UIView animateWithDuration:0.001
                      delay:0
                    options:UIViewAnimationOptionCurveEaseInOut
                 animations:^(void) {
                     Button2.frame = frame;
                 }
                 completion:nil];
}

Answer 2

试试这个：

-(IBAction)Counter:(id)sender {
   [self moveButton];
}

-(void)moveButton {
   int xCo = arc4random() %(int)(self.view.frame.size.width-Butoon2.frame.size.width);
   int yCo = arc4random() %(int)(self.view.frame.size.height-Butoon2.frame.size.height);
   CGRect frame = Butoon2.frame;
   frame.origin.x = xCo;
   frame.origin.y = yCo;

   [UIView beginAnimations:nil context:nil];

   [UIView setAnimationDuration:0.001];
   self.Button2.frame = frame;
   [UIView commitAnimations];
}

按下时如何使按钮随机移动
