只看楼主收藏回复

#import <UIKit/UIKit.h>
@interface UIColor (ImageWithColor)
- (UIImage *)imageWithColor;
@end
#import "UIColor+ImageWithColor.h"
@implementation UIColor (ImageWithColor)
- (UIImage *)imageWithColor{
CGRect rect = CGRectMake(0.0f, 0.0f, 1.0f, 1.0f);
UIGraphicsBeginImageContext(rect.size);
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSetFillColorWithColor(context, [self CGColor]);
CGContextFillRect(context, rect);
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return image;
}
@end
