Ios 如何通过单击移动UIView？

我不确定我能否恰当地描述它。这是一种UIView，我们只看到它的一部分（可能带有箭头，可能在屏幕底部）。用户可以点击它，这个视图会全屏显示（通常开发者会在这里留下一些附加信息）。我怎样才能做到

---

我只需要设置视图Y坐标的逻辑，当用户点击按钮时。这将设置动画，并在使用Y坐标设置重新设置图幅时，如下所示：

 yourview.frame = CGRectMake(0,280,320,568);

  [UIView animateWithDuration:2
                              delay:0.1
                            options: UIViewAnimationOptionTransitionFlipFromBottom
                         animations:^{

                            yourview.frame = CGRectMake(0, 0, 320, 568);  
                    }
                     completion:^(BOOL finished){
                   }];

另请参见此示例：

在上面的github演示中，您正在寻找它的输出，如下所示：

查看UIView参考：

具体而言：

@property(nonatomic) CGPoint center

及

例如：

[UIView animateWithDuration:2.0 animations:^{
        myView.center = CGPointMake(self.view.center.x, self.view.center.y + myOffset);
    }];

持续时间以秒为单位。在这种情况下，需要2秒

如果使用的是

AutoLayout

，则可能需要更改

layout常量

，而不是

center

属性

关于布局约束：

查看

常量

属性。您还可以从Interface Builder中拖动约束出口并访问其

常量。一旦你对它有了一点了解，它就会变得非常简单。
试试这个：

-(void)show
{
    [viewObj setFrame:CGRectMake(viewObj.frame.origin.x,viewObj.frame.origin.y,viewObj.frame.size.width, viewObj.frame.size.height)];//Here "viewObj.frame.origin.y" means 568
    [UIView animateWithDuration:0.5 animations:^
     {
         [viewObj setFrame:CGRectMake(viewObj.frame.origin.x,0,viewObj.frame.size.width, viewObj.frame.size.height)];
     }
     completion:^(BOOL finished)
     {
     }];
}

-(void)hide
{
    [viewObj setFrame:CGRectMake(viewObj.frame.origin.x,viewObj.frame.origin.y,viewObj.frame.size.width, viewObj.frame.size.height)];//Here "viewObj.frame.origin.y" means 0
    [UIView animateWithDuration:0.5 animations:^
     {
         [viewObj setFrame:CGRectMake(viewObj.frame.origin.x,568,viewObj.frame.size.width, viewObj.frame.size.height)];
     }
     completion:^(BOOL finished)
     {
     }];
}

-(void)show
{
    [viewObj setFrame:CGRectMake(viewObj.frame.origin.x,viewObj.frame.origin.y,viewObj.frame.size.width, viewObj.frame.size.height)];//Here "viewObj.frame.origin.y" means 568
    [UIView animateWithDuration:0.5 animations:^
     {
         [viewObj setFrame:CGRectMake(viewObj.frame.origin.x,0,viewObj.frame.size.width, viewObj.frame.size.height)];
     }
     completion:^(BOOL finished)
     {
     }];
}

-(void)hide
{
    [viewObj setFrame:CGRectMake(viewObj.frame.origin.x,viewObj.frame.origin.y,viewObj.frame.size.width, viewObj.frame.size.height)];//Here "viewObj.frame.origin.y" means 0
    [UIView animateWithDuration:0.5 animations:^
     {
         [viewObj setFrame:CGRectMake(viewObj.frame.origin.x,568,viewObj.frame.size.width, viewObj.frame.size.height)];
     }
     completion:^(BOOL finished)
     {
     }];
}
