IOS中UIImage和UIColor相互转化

//UIColor 转UIImage

- (UIImage*) createImageWithColor: (UIColor*) color

{

CGRect rect=CGRectMake(0, 0, 1, 1);

UIGraphicsBeginImageContext(rect.size);

CGContextRef context = UIGraphicsGetCurrentContext();

CGContextSetFillColorWithColor(context, [color CGColor]);

CGContextFillRect(context, rect);

UIImage *senderImage = UIGraphicsGetImageFromCurrentImageContext();

UIGraphicsEndImageContext();

return senderImage;

}

//UIImage转UIColor

[UIColor colorWithPatternImage:[UIImage imageNamed:@"image.png"]];
