iOS sdwebimage 特殊圖片錯誤的問題

標籤：

 

原先sdwebimage是使用

CGImageGetColorSpace(imageRef),

但這個的有些圖片會報錯

Aug  8 15:52:13 game--Pro.local[88338] <Error>: CGBitmapContextCreate: unsupported color space.Aug  8 15:52:13 game--Pro.local[88338] <Error>: CGContextDrawImage: 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.Aug  8 15:52:13 game--Pro.local[88338] <Error>: CGBitmapContextCreateImage: invalid context 0x0.

然後修改為下面代碼可以解決上面這個錯誤

CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();    CGContextRef context = CGBitmapContextCreate(NULL, width,                                                 height,                                                 CGImageGetBitsPerComponent(imageRef),                                                 0,//                                                 CGImageGetColorSpace(imageRef),                                                 colorSpace,                                                 kCGBitmapByteOrderDefault | kCGImageAlphaPremultipliedFirst);
