提问by MatterGoal
How can i change Size of a Frame view and keep origin position? I tried with this code (but it didn't work):
如何更改框架视图的大小并保持原点位置？我尝试使用此代码（但没有用）：
myview.frame.size = CGSizeMake(23.0,50.0);

Here's how to do it with just one line of code:
以下是仅使用一行代码的方法：
myview.frame = CGRectMake(23, 50, myview.frame.size.width, myview.frame.size.height);
or
或者
[myview setFrame:CGRectMake(23, 50, myview.frame.size.width, myview.frame.size.height)];

You need to set the whole frame at once. Try:
您需要一次设置整个框架。尝试：
CGRect newFrame = myview.frame;
newFrame.size = CGSizeMake(23.0, 50.0);
myview.frame = newFrame;

Not that I am aware of. Rather than change your view's frame property, you can change the bounds property so regardless of what you set for x and y, it wont affect your view position. Make sure that you use 0 for x and y.
不是我所知道的。您可以更改 bounds 属性，而不是更改视图的 frame 属性，因此无论您为 x 和 y 设置什么，它都不会影响您的视图位置。确保对 x 和 y 使用 0。
self.myView.bounds = CGRectMake(0,0, newWidth, newHeight);
