修改icon颜色

- (UIImage*)imageWithImageName:(NSString*)nameimageColor:(UIColor*)imageColor {

    UIImage *image = [UIImage imageNamed:name];

    UIGraphicsBeginImageContextWithOptions(image.size, NO, 0.0f);

    [imageColorsetFill];

    CGRectbounds =CGRectMake(0,0, image.size.width, image.size.height);

    UIRectFill(bounds);

    [imagedrawInRect:bounds blendMode:kCGBlendModeDestinationIn alpha:1.0f];

    UIImage *tintedImage = UIGraphicsGetImageFromCurrentImageContext();

    UIGraphicsEndImageContext();

     returntintedImage;

}

对单色icon，及背景为透明起作用
