iOS中iconfont(图标字体)的基本使用

常用的分类方法

// UIImage分类
+ (UIImage *)imageWithIcon:(NSString *)iconCode size:(NSUInteger)size color:(UIColor *)color {
    CGSize imageSize = CGSizeMake(size, size);
    UIGraphicsBeginImageContextWithOptions(imageSize, NO, [[UIScreen mainScreen] scale]);
    UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, size, size)];
    label.font = [UIFont fontWithName:@"icomoon" size:size];
    label.text = iconCode;
    if (color) {
        label.textColor = color;
    }
    [label.layer renderInContext:UIGraphicsGetCurrentContext()];
    UIImage *retImage = UIGraphicsGetImageFromCurrentImageContext();
    return retImage;
}

+ (UIImage *)imageWithIcon:(NSString *)iconCode inFont:(NSString *)fontName size:(NSUInteger)size color:(UIColor *)color {
    CGSize imageSize = CGSizeMake(size, size);
    UIGraphicsBeginImageContextWithOptions(imageSize, NO, [[UIScreen mainScreen] scale]);
    UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, size, size)];
    label.font = [UIFont fontWithName:fontName size:size];
    label.text = iconCode;
    if (color) {
        label.textColor = color;
    }
    [label.layer renderInContext:UIGraphicsGetCurrentContext()];
    UIImage *retImage = UIGraphicsGetImageFromCurrentImageContext();
    return retImage;
}

// UILabel分类
- (void)labelIconWithSize:(CGFloat)size text:(NSString *)text color:(UIColor *)color
{
    self.font = [UIFont fontWithName:@"icomoon" size:size];
    self.text = text;
    [self setTextColor:color];
}
