[iOSDev] modifying layer that is being finalized

Lauct — Thu, 12 Jan 2012 18:58:47 +0000

modifying layer that is being finalized

solution:
用

[view removeFromSuperview];

取代

[view release];

分析:

通常發生在從UI上移除某個View
release 或修改了已經release的view

移除view的一般操作顺序應該是
1:removeFromSuperview
2:release view

PS. autorelease 就不用再release了
