Question

我开始尝试从应用程序商店重新创建购买按钮，这需要两个阶段的点击才能购买。我动画按钮扩展。到目前为止我有这个

[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.75];

sender.autoresizesSubviews = NO;
sender.clipsToBounds = NO;
sender.frame = CGRectMake(63,326,200,37);

[UIView commitAnimations];

只会导致按钮变大，根本没有动画效果。我做错了什么或有没有其他人实现过这种按钮行为？

编辑：

- (IBAction) buyButtonAction: (UIButton *) sender {

[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.5];
[UIView setAnimationDelay:0.5];
[UIView setAnimationCurve:UIViewAnimationCurveEaseIn];

sender.clipsToBounds = NO;

sender.frame = CGRectMake( CGRectGetMinX( sender.frame) - 30, CGRectGetMinY(sender.frame), 200, 37);
[sender setTitle:@"Touched Touched Touched" forState:UIControlStateNormal];


[UIView commitAnimations];
}

您的目标是不支持Block的iOS吗？

我使用以下令人作呕的简单代码实现了“触摸动画按钮”。

[UIView animateWithDuration:0.5 animations:^{
    self.navigationItem.rightBarButtonItem.title = @"Quoting...";
}];

或者，如果你不能支持块（这也包括你去那条路线时注释掉的块），这段代码看起来也可以用来触摸触摸按钮：

-(IBAction) clicked:(UIButton*)sender{
    [UIView beginAnimations:nil context:nil];
    [UIView setAnimationDuration:0.5];
    [UIView setAnimationDelay:0];
    [UIView setAnimationCurve:UIViewAnimationCurveEaseIn];
    //[UIView animateWithDuration:2.5 animations:^{

    sender.autoresizesSubviews = NO;
    sender.clipsToBounds = NO;
    sender.frame = CGRectMake(63,326,200,37);

    //sender.frame = CGRectMake( CGRectGetMinX( self.theButton.frame) - 100, CGRectGetMinY(self.theButton.frame), 300, 40);
    //[sender setTitle:@"Touched Touched Touched" forState:UIControlStateNormal];
//}];

UIView动画改变了按钮的大小
