【问题描述】：

如何将 UIView 从左向右移出屏幕，然后从左侧再次将其移入屏幕？！！

提前致谢，

【问题讨论】：

你能单独做这两件事吗？

【参考方案1】：

您所要做的就是为视图的 x 原点位置设置动画，并使用设备屏幕来确定多少。所以对于右边的屏幕外：

CGRect screenRect = [[UIScreen mainScreen] bounds];
CGFloat screenWidth = screenRect.size.width;

[UIView animateWithDuration:0.5 delay:0 options:UIViewAnimationOptionCurveEaseInOut animations:^
    _yourView.frame = CGRectMake(screenRect.size.width, _yourView.frame.origin.y, _yourView.frame.size.width, _yourView.frame.size.height);

                 completion:^(BOOL finished) 
                     //position screen left after animation
                     _yourView.frame = CGRectMake(-screenRect.size.width, _yourView.frame.origin.y, _yourView.frame.size.width, _yourView.frame.size.height);
                 ];

对于屏幕返回 0.0 x 位置或任何您的起点：

[UIView animateWithDuration:0.5 delay:0 options:UIViewAnimationOptionCurveEaseInOut animations:^
    _yourView.frame = CGRectMake(0.0, _yourView.frame.origin.y, _yourView.frame.size.width, _yourView.frame.size.height);

                 completion:^(BOOL finished) 
                     //do something after animation
                 ];

【参考方案2】：

离开屏幕：

CGRect frame = viewToMove.frame;
frame.origin.x = self.view.frame.size.width;
viewToMove.frame = frame;

要将视图移回屏幕：

CGRect frame = viewToMove.frame;
frame.origin.x = 0;
viewToMove.frame = frame;

【讨论】：

这会将它从屏幕上移到右侧。根据他们希望它从屏幕上移出的位置，他们会相应地调整 x 或 y。

【参考方案3】：

//Store your view's original rect
UIRect originRect = yourView.frame;

[UIView animateWithDuration:0.25 animations:^

//create new rect and set its X coord to phone's width
CGrect rect = originRect;
rect.origin.x = self.view.frame.size.width;
yourView.frame = rect;

 completion:^(BOOL finished)

   // when animation finished animating start new animation 
   //to bring your view to its original position

   [UIView animateWithDuration:0.25 animation:^

   yourView.frame = originRect;

   ];

];

【讨论】：

稍微清理一下，这对我来说是最简单的。

【参考方案4】：

此代码将在 0.3 秒内将其向右移动，然后在接下来的 0.3 秒内再次从左侧返回到当前位置。

CGRect backToOriginal = Yourview.frame;
CGRect frameOnRight = CGRectMake ( screenWidth,backToOriginal.origin.y,backToOriginal.frame.size.width,backToOriginal.frame.size.height);

[UIView animateWithDuration:0.3 delay:0.0 options:UIViewAnimationOptionCurveEaseIn animations:^ Yourview.frame = frameOnRight;  completion:^(BOOL finished)[UIView setFrame: screenLeft;] [UIView animateWithDuration:0.3 delay:0.0 options:UIViewAnimationOptionCurveEaseIn animations:^ Yourview.frame = backToOriginal;  ];

这段代码在语法上一定有错误，因为我现在没有坐在 MAC 上。

【参考方案5】：

//向左移动视图

[UIView animateWithDuration:0.5
                      delay:1.0
                    options: UIViewAnimationCurveEaseOut
                 animations:^
                     self.yourView.frame = CGRectMake(distanceToLeft, distanceFromTop, yourView.width, yourView.height);
                     
                 completion:^(BOOL finished)
                     NSLog(@"Moved to left!");
                 ];

// 回到原来的位置

[UIView animateWithDuration:0.5
                      delay:1.0
                    options: UIViewAnimationCurveEaseOut
                 animations:^
                     self.yourView.frame = CGRectMake(originalX, OriginalY, yourView.Width, yourView.height);
                 
                 completion:^(BOOL finished)
                     NSLog(@"Back to normal!");
                 ];
