IOS cotrols隐藏匆匆像机器人 [英] IOS cotrols hide and gone like android

问题描述

我已经使用了故事情节与自动布局我的UI设计。基本上，在机器人有三种不同的属性将在那里例如可见和隐形和走了。

I have used storyboard with autolayout for my UI design. Basically in android there are three different properties will be there like Visible and Invisible and gone.

例如：

   1) android:visibility="gone" // used to hide the control and as well as space
      (or)
      CONTROLNAME.setVisibility(View.GONE);
   2)  android:visibility="invisible" // used to hide the control but it will take space
      (or)
      CONTROLNAME.setVisibility(View.INVISIBLE);

在IOS，

  1) ?
  2) [CONTROLNAME setHidden:TRUE]; // used to hide the control but it will take space

有关充当消失在IOS我已经搜索从谷歌，但我可以没能找到解决方案。

for act as a gone in IOS i have searched from google but i can't able to find the Solution.

推荐答案

要删除一个视图（控制）所占用的空间可以降低尺寸其框架零或视图层次结构中移除。即通过调用 removeFromSuperview 上的控制。

To remove the space occupied by a view(control) can either reduce the size of its frame to zero or remove it from the view hierarchy. I.e. by calling removeFromSuperview on the control.

例如，如果你要删除一个的UITextField （比如控件名称），那么你就可以占用的空间无论是使用：

For example if you have to remove the space occupied by a UITextField (say CONTROLNAME), then you can either use:

CGRect tempFrame = CONTROLNAME.frame;
CGSize currentSize = tempFrame.size; //for later use
tempFrame.size = CGSizeZero;
CONTROLNAME.frame = tempFrame;

或

CGRect currentFrame = CONTROLNAME.frame; //for later use
[CONTROLNAME removeFromSuperview];

更新：

在第一种情况下，你将不得不存储较早大小带回控制到其初始位置。

In the first case you will have to store the earlier size to bring back the control to its initial position.

CGRect tempFrame = CONTROLNAME.frame;
tempFrame.size = currentSize; //set to initial value
CONTROLNAME.frame = tempFrame;

在第二种情况下，你将不得不存储控制的框架，使其恢复到初始位置的（以及控件本身，如果它是一个局部变量或弱实例变量）的。

In the second case you will have to store the frame of the control to bring it back to its initial position (and also the control itself if it is a local variable or weak instance variable).

CONTROLNAME.frame = currentFrame;
