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;
