UiScrollView滚动UiView

Question

在我的viewcontroller中输入了scrollview中的所有对象。 scrollView中的一个按钮可以创建一个动画。

scrollView离开页面-80.0 orgine.y 到目前为止一切都那么好..现在我想要当你点击按钮滚动视图然后回到-80.0到+80.0自动返回到原来的位置所以...你能告诉我你最好的方法吗？此？

这是按下时按下按钮的动作......

- (IBAction)AcceptFriendRequest:(id)sender {

    PFObject *SelectedUser = [self.UtentiInAttesa objectAtIndex:[sender tag]];
    [SelectedUser setObject:@"Confermato" forKey:@"STATO"];

    [SelectedUser saveInBackground];



     [UIView beginAnimations:nil context:NULL];
     [UIView setAnimationDelegate:self];
     [UIView setAnimationDuration:0.2];
     [UIView setAnimationBeginsFromCurrentState:YES];
     FFScrollView.frame = CGRectMake(FFScrollView.frame.origin.x, (FFScrollView.frame.origin.y - 80.0), FFScrollView.frame.size.width, FFScrollView.frame.size.height);
        [UIView setAnimationRepeatAutoreverses:YES];

     [UIView commitAnimations];



}

在您的按钮事件处理程序

中

- (IBAction)myBtnClicked:(id)sender {
    // Create new CGRect indicate place where you would scroll to.
    // Assume it is called `originalRect`
    // Use the following method, it should work
    [FFScrollView.scroll scrollRectToVisible:originalRect animated:YES];
}
