iOS：使用数组的 AutoresizingMask？

发布于 2024-11-30 10:21:41 字数 529 浏览 2 评论 0原文

是否可以为 UIView 的 autoresizingMask 属性提供一个数组？我想要这样做的原因是我有一些条件来确定我想要将哪些 autoresizingMask 属性添加到我的视图中。

因此，不仅仅是使用：

self.view.autoresizingMask = UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleWidth;

我想做类似的事情：

if (addMargin) {
   [items addObject:UIViewAutoresizingFlexibleRightMargin];
}
if (addWidth) {
   [items addObject:UIViewAutoresizingFlexibleWidth];
}

// Add to property
self.view.autoresizingMask = items;

所以我基本上想有条件地设置此属性的项目。

原文

Is it possible to provide an array to the autoresizingMask property of UIView? The reason I want to do this is that I have some conditions which determine which autoresizingMask properties I want to add to my my view.

So, instead of just using:

self.view.autoresizingMask = UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleWidth;

I want to do something like:

if (addMargin) {
   [items addObject:UIViewAutoresizingFlexibleRightMargin];
}
if (addWidth) {
   [items addObject:UIViewAutoresizingFlexibleWidth];
}

// Add to property
self.view.autoresizingMask = items;

So I basically want to conditionally set the items of this property.

有点面具了。只需将其与您想要的进行按位或即可。

if(addMargin)
    self.view.autoresizingMask |= UIViewAutoresizingFlexibleRightMargin;
if(addWidth)
    self.view.autoresizingMask |= UIViewAutoresizingFlexibleWidth;

要重置掩码，您可以将其设置为 0，或者如果您想删除特定属性，您可以将其取反并与掩码进行按位与：

if(removeMargin)
    self.view.autoresizingMask &= ~UIViewAutoresizingFlexibleRightMargin;

It's a bit mask. Just bitwise-OR it with the one you want.

if(addMargin)
    self.view.autoresizingMask |= UIViewAutoresizingFlexibleRightMargin;
if(addWidth)
    self.view.autoresizingMask |= UIViewAutoresizingFlexibleWidth;

To reset the mask, you can set it to 0, or if you want to remove a particular attribute you can negate it and bitwise-AND the mask with it:

if(removeMargin)
    self.view.autoresizingMask &= ~UIViewAutoresizingFlexibleRightMargin;

自动调整大小只是一个位掩码。

UIViewAutoresizing resize = 0;
if (addMargin) {
    resize = resize | UIViewAutoresizingFlexibleRightMargin;
}
if (addWidth) {
    resize = resize | UIViewAutoresizingFlexibleWidth;
}

self.view.autoresizingMask = resize

Autoresizing is just a bit mask.

UIViewAutoresizing resize = 0;
if (addMargin) {
    resize = resize | UIViewAutoresizingFlexibleRightMargin;
}
if (addWidth) {
    resize = resize | UIViewAutoresizingFlexibleWidth;
}

self.view.autoresizingMask = resize
