在Mac OS 10.8上,我在我的应用程序中收到以下警告:
CoreAnimation: warning, deleted thread with uncommitted CATransaction;
它建议在环境中打开CA_DEBUG_TRANSACTIONS = 1来记录回溯,我这样做了.
这是我的回溯的顶部:
0 QuartzCore 0x00007fff88a84b95 _ZN2CA11Transaction4pushEv + 219 1 QuartzCore 0x00007fff88a8476d _ZN2CA11Transaction15ensure_implicitEv + 273 2 QuartzCore 0x00007fff88a8bb6a _ZN2CA5Layer12begin_changeEPNS_11TransactionEjRP11objc_object + 44 3 QuartzCore 0x00007fff88a8cb4e _ZN2CA5Layer10set_boundsERKNS_4RectEb + 452 4 QuartzCore 0x00007fff88a8c908 -[CALayer setBounds:] + 189
有谁知道这个警告是什么,以及如何避免它？
