使用addSubview添加视图时，会将视图大小调整为其父级 [英] Making view resize to its parent when added with addSubview

问题描述

使用addSubview时遇到问题。

I'm having a problem when using addSubview.

示例代码：

ParentView *myParentView = [[ParentView alloc] initWithNibName:@"ParentView " bundle:nil];
ChildeView *myChildeView = [[ChildeView alloc] initWithNibName:@"ChildeView" bundle:nil];

//...  parent frame resized with setFrame lets say to x:0, y:0, W:320, H:411

[[myParentView view] addSubview: [myChildeView view]];

我的孩子在添加时比父母大，并且不会将其框架调整为父边界。我无法在父级上使用剪辑子视图，并且如果不再次调整父级框架，则自动调整子视图似乎不起作用。是否存在一个属性，使子视图自动调整为其父级边界，而不对每个子节点使用setFrame？

My child when added is bigger then the parent, and does not resize its frame to parent bounds. I can't use "clip subviews" on the parent, and "Autoresize Subviews" seems not to work if the parent frame is not resized again. Is there a property that makes a subview resize automatically to its parent's bounds without using setFrame on every child?

推荐答案

如果你不是使用自动布局，您是否尝试过设置子视图的自动调整大小？试试这个：

If you aren’t using Auto Layout, have you tried setting the child view’s autoresize mask? Try this:

myChildeView.autoresizingMask = (UIViewAutoresizingFlexibleWidth |
                                 UIViewAutoresizingFlexibleHeight);

此外，您可能需要致电

myParentView.autoresizesSubviews = YES;

以使父视图在其帧更改时自动调整其子视图的大小。

to get the parent view to resize its subviews automatically when its frame changes.

如果您仍然在父视图框架之外看到子视图绘图，则父视图很可能不会剪切其内容。要解决此问题，请致电

If you’re still seeing the child view drawing outside of the parent view’s frame, there’s a good chance that the parent view is not clipping its contents. To fix that, call

myParentView.clipsToBounds = YES;
