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"]];
