最近做项目遇到一种情况，就是一段文字有一个或都两个关键字是比较特殊，字号或者颜色是有点区别，所以自己也尝试扩展一个NSString类，下面的代码主要是针对项目而言：
具体展示：
// NSString+Extension.h
#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>
@interface NSString (Extension)
/** 两个string同种颜色不同字号 */
+ (NSMutableAttributedString *)ym_setAttribute:(NSString *)firstStr secondString:(NSString *)secondStr formerFont:(UIFont *)firstFont latterFont:(UIFont *)secondFont color:(UIColor *)color;
/** 两个string不同颜色不同字号 */
+ (NSMutableAttributedString *)ym_setattributes:(NSString *)firstStr secondString:(NSString *)secondStr formerFont:(UIFont *)firstFont latterFont:(UIFont *)secondFont firstColor:(UIColor *)firstColor secondColor:(UIColor *)secondColor;
/** 两个关键字同颜色同字号 */
+ (NSMutableAttributedString *)ym_setAttributes:(NSString *)normalStr normalFont:(UIFont *)normalFont normalColor:(UIColor *)normalColor firstSpecialStr:(NSString *)firstSpecialStr : (NSString *)secondSpecialStr specialFont:(UIFont *)specialFont specialColor:(UIColor *)specialColor;
/** 两个关键字不同颜色不字号 */
+ (NSMutableAttributedString *)ym_setAttributes:(NSString *)normalStr normalFont:(UIFont *)normalFont normalColor:(UIColor *)normalColor firstSpecialStr:(NSString *)firstSpecialStr : (NSString *)secondSpecialStr firstSpecialFont:(UIFont *)firstSpecialFont firstSpecialColor:(UIColor *)firstSpecialColor secondSpecialFont:(UIFont *)secondSpecialFont secondSpecialColor:(UIColor *)secondSpecialColor;
@end
// NSString+Extension.m
#import "NSString+Extension.h"
@implementation NSString (Extension)
/** 两个string同种颜色不同字号 */
+ (NSMutableAttributedString *)ym_setAttribute:(NSString *)firstStr secondString:(NSString *)secondStr formerFont:(UIFont *)firstFont latterFont:(UIFont *)secondFont color:(UIColor *)color
{
NSString *string = [NSString stringWithFormat:@"%@%@",firstStr,secondStr];
NSMutableAttributedString *attrrSting = [[NSMutableAttributedString alloc] initWithString:string];
NSUInteger firstLength = [firstStr length];
NSUInteger secondLength = [secondStr length];
[attrrSting addAttribute:NSFontAttributeName value:firstFont range:NSMakeRange(0, firstLength)];
[attrrSting addAttribute:NSFontAttributeName value:secondFont range:NSMakeRange(firstLength, secondLength)];
[attrrSting addAttribute:NSForegroundColorAttributeName value:color range:NSMakeRange(0, firstLength + secondLength)];
return attrrSting;
}
/** 两个string不同颜色不同字号 */
+ (NSMutableAttributedString *)ym_setattributes:(NSString *)firstStr secondString:(NSString *)secondStr formerFont:(UIFont *)firstFont latterFont:(UIFont *)secondFont firstColor:(UIColor *)firstColor secondColor:(UIColor *)secondColor

return attrSting;
}
/** 两个关键字同颜色同字号 */
+ (NSMutableAttributedString *)ym_setAttributes:(NSString *)normalStr normalFont:(UIFont *)normalFont normalColor:(UIColor *)normalColor firstSpecialStr:(NSString *)firstSpecialStr :(NSString *)secondSpecialStr specialFont:(UIFont *)specialFont specialColor:(UIColor *)specialColor
{
NSMutableAttributedString *attrString = [[NSMutableAttributedString alloc] initWithString:normalStr];
NSRange oneRange = [normalStr rangeOfString:firstSpecialStr];
NSRange twoRange = [normalStr rangeOfString:secondSpecialStr];
//整个字符串的颜色和字体
[attrString addAttribute:NSFontAttributeName value:normalFont range:NSMakeRange(0, normalStr.length)];
[attrString addAttribute:NSForegroundColorAttributeName value:normalColor range:NSMakeRange(0, normalStr.length)];
//第一个特殊字符串的颜色和字体
