CoreAnimation未提交的CATransaction警告 [英] CoreAnimation uncommitted CATransaction warning

问题描述

在Mac OS 10.8上，我的应用程序收到以下警告:

On Mac OS 10.8 I'm getting the following warning in my app:

CoreAnimation: warning, deleted thread with uncommitted CATransaction;

CoreAnimation: warning, deleted thread with uncommitted CATransaction;

这建议我在环境中打开CA_DEBUG_TRANSACTIONS = 1来记录回溯.

It suggests turning on CA_DEBUG_TRANSACTIONS=1 in environment to log backtraces, which I did.

这是我的追踪记录的顶部

This is the top of my backtrace:

0   QuartzCore          0x00007fff88a84b95 _ZN2CA11Transaction4pushEv + 219
1   QuartzCore          0x00007fff88a8476d _ZN2CA11Transaction15ensure_implicitEv + 273

4   QuartzCore          0x00007fff88a8c908 -[CALayer setBounds:] + 189

有人知道这个警告是什么，以及如何避免它?

Does anyone know what this warning is, and how to avoid it?

推荐答案

我发现将有问题的代码包装为显式的CATransaction并禁用了操作，该警告就消失了.

I found that wrapping the offending code an explicit CATransaction with actions disabled made the warning go away.

即

[CATransaction begin];
[CATransaction setDisableActions:YES];
layer.bounds = CGRectMake(0, 0, 1000, 1000);
[CATransaction commit];
