Question

在xcode中,当我打开文本字段的.xib中的十进制键盘键盘选项,并运行应用程序时,收到此错误:

Jun 13 01:22:38 Nicholas-Gibsons-iPhone Quick Utilities[1009] <Error>: 
CGContextSetFillColorWithColor: 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.
