How to move UIButton programmatically. Objective-C Xcode
提问by SamBo
I've seen some solutions, none of which have worked for my issue.
我已经看到了一些解决方案，但没有一个对我的问题有效。
I have a UIButtoncreated by simply drag/dropping into the UIViewControllerin Storyboard editor.
我UIButton通过简单地拖放到UIViewController故事板编辑器中创建了一个。
The UIButtonhas an outlet linked to the .h file for the UIViewControllerassociated to that view. It is also Synthesized in the .mfile.
在UIButton具有连接到.h文件的一个出口UIViewController相关联的那个视图。它也在.m文件中合成。
@property (strong, nonatomic) IBOutlet UIButton *answerButton;
I want to change the location of the button during run time like this;
我想在运行时像这样更改按钮的位置；
CGRect btFrame = answerButton.frame;
btFrame.origin.x = xOne;
btFrame.origin.y = yOne;
answerButton.frame = btFrame;
However whenever I try this, the button refuses to move.
但是，每当我尝试此操作时，按钮都拒绝移动。
All other editing functions (like setTitleetc) are functional, but for some reason the frame won't move how I want it to.
所有其他编辑功能（如setTitle等）都可以使用，但由于某种原因，框架不会按照我想要的方式移动。

Simply uncheck "Use Autolayout" in the file inspector..
只需在文件检查器中取消选中“使用自动布局”即可。

-(IBAction)moveTheButton:(id)sender;
@end
.m file
.m 文件
-(IBAction)moveTheButton:(id)sender{
CGRect btFrame = theButton.frame;
btFrame.origin.x = 90;
btFrame.origin.y = 150;
theButton.frame = btFrame;
}
}
This code moves the button from one point to another.
此代码将按钮从一个点移动到另一个点。

Replace your code by the below, which includes code to remove auto resizing mask.
用下面的代码替换您的代码，其中包括删除自动调整大小掩码的代码。
CGRect btFrame = answerButton.frame;
btFrame.origin.x = xOne;
btFrame.origin.y = yOne;
answerButton.autoresizingMask = UIViewAutoresizingNone;
answerButton.frame = btFrame;
