CGDataProviderRef dataProvider = CGImageGetDataProvider(screenShot); CFDataRef data = CGDataProviderCopyData(dataProvider); CGDataProviderRelease(dataProvider); NSString *imagePathLocation = [destinationPath stringByAppendingString:[@"/" stringByAppendingString:DesktopImage]]; [[NSFileManager defaultManager]createFileAtPath: imagePathLocation contents:nil attributes:nil]; fileHandleForImage = [NSFileHandle fileHandleForWritingAtPath:imagePathLocation]; NSData * data1 = (NSData *)data; [fileHandleForImage writeData:data1];

It's toll-free bridged, so you just have to cast it.

NSData *myData = (NSData *)myCFDataRef;
