iOS 富文本~设置字体大小和颜色

//联系人:石虎 QQ:1224614774 昵称:嗡嘛呢叭咪哄



一、富文本效果图:

二、富文本实现代码:

//1.初始化UILabel

UILabel *introLabel = [UILabel
lableFrame:CGRectZero
title:nil
backgroundColor:[UIColor
clearColor]
font:kGlobalFontSize_28
textColor:[UIColor
purpleColor]];

//2.初始化富文本

NSMutableAttributedString *indroStr = [NSMutableAttributedString
setupAttributeString:@"张琼在新神力酒店工作"
rangeText:@"张琼"
textColor:OKColorRGB(236,
198,
128)];

introLabel.attributedText = indroStr;

introLabel.frame = CGRectMake(10,
100,500,
40);

[self addSubview:introLabel];

//注意:效果是@“张琼在新神力酒店上班”可以设置一个颜色,这字符串中的@“张琼”可以设置其它的颜色和字体大小.

三、富文本实现的分类方法

//分类

#pragma mark - 创建UILabel

+ (UILabel*)lableFrame:(CGRect)frame title:(NSString *)title backgroundColor:(UIColor*)color
font:(UIFont*)font textColor:(UIColor*)textColor

{

    UILabel *lable=[[UILabel
alloc]initWithFrame:frame];

    lable.text=title;

    lable.font=font;

    [lable setBackgroundColor:color];

    lable.textColor=textColor;

    return lable;

}

#pragma mark - 富文本设置部分字体颜色

+ (NSMutableAttributedString *)setupAttributeString:(NSString *)text rangeText:(NSString
*)rangeText textColor:(UIColor *)color  {

    NSRange hightlightTextRange = [text
rangeOfString:rangeText];

    NSMutableAttributedString *attributeStr = [[NSMutableAttributedString
alloc]
initWithString:text];

    if (hightlightTextRange.length >
0) {

        [attributeStr addAttribute:NSForegroundColorAttributeName

                             value:color

                             range:hightlightTextRange];

        [attributeStr addAttribute:NSFontAttributeName
value:[UIFont
boldSystemFontOfSize:14.0f]
range:hightlightTextRange];

        return attributeStr;

    }else {

        return [rangeText
copy];

    }

}

谢谢!!!
