问题描述
它快把我逼疯了！我工作的绘图应用程序。比方说，我在的UIView 称为表工作。
It's driving me crazy! I am working on a drawing application. Let's say I am working on a UIView called sheet.
我添加了一些子层这个观点（ [sheet.layer addSublayer：...] ），然后我要画到他们。要做到这一点我创建一个 CGImageRef ，并把它变成层的内容。但它的动画，我不希望出现这种情况。
I am adding some sublayers to this view ([sheet.layer addSublayer:...]) and then I want to draw into them. To do so I am creating a CGImageRef and putting it into the layer's contents. But it's animated and I don't want that.
我什么都试过：
-
removeAnimationForKey： -
removeAllAnimations - 设置操作字典
- 使用actionlayer
代表 -
[CATransaction setDisableAnimations：YES]
removeAnimationForKey:removeAllAnimations- set the actions dictionary
- using the actionlayer
delegate [CATransaction setDisableAnimations:YES]
它似乎是正确的。我不明白为什么这层仍是动画; _;结果
难道我做错了什么？有一个秘密的方式？
It's seems correct. I don't understand why this layer is still animated ;_;
Am I doing something wrong? Is there a secret way?
推荐答案
您必须通过在CATransaction包裹你的code明确禁用动画
You have to explicitly disable animations by wrapping your code in a CATransaction
[CATransaction begin];
[CATransaction setValue:(id)kCFBooleanTrue
forKey:kCATransactionDisableActions];
layer.content = someImageRef;
[CATransaction commit];
随意张贴一些code。
Feel free to post some code.
最好的，
