CGContextSaveGState錯誤

Question

我正在iphone應用程序，一旦它開始顯示我錯誤，沒有例外，我真的很害怕這個錯誤，任何人都可以告訴我爲什麼會發生這種情況？

<Error>: CGContextSaveGState: invalid context 0x0. This is a serious error. This application, or a library it uses, is using an invalid context and is thereby contributing to an overall degradation of system stability and reliability. This notice is a courtesy: please fix this problem. It will become a fatal error in an upcoming update.

iOS 7中存在問題。這是Apple正在處理的已知問題。應該在下一個beta版本中修復。
