UIColor 转UIImage
- (UIImage*) createImageWithColor: (UIColor*) color
{
CGRect rect=CGRectMake(0.0f, 0.0f, 1.0f, 1.0f);
UIGraphicsBeginImageContext(rect.size);
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSetFillColorWithColor(context, [color CGColor]);
CGContextFillRect(context, rect);
UIImage *theImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return theImage;
}
UIImage转UIColor
[UIColor colorWithPatternImage:[UIImageimageNamed:@"EmailBackground.png"]]
- (UIImage*) createImageWithColor: (UIColor*) color
