QExtension 1.1.7
- 由
- QianChia
- Foundation & UIKit 类的扩展方法。
GitHub：QianChia ｜ Blog：QianChia(Chinese)
安装
手动
- 将
QExtension文件夹下的所有源文件拖到您的项目中。 - 导入主头文件：
#import "QExtension.h"
示例
1、NSArray 扩展
1.1 LocaleLog 方法
-
本地化打印输出
Xcode 没有针对国际化语言做特殊处理，直接 Log 数组，只打印 UTF8 的编码，不能显示中文。 - (NSString *)descriptionWithLocale:(nullable id)locale; 重写这个方法，就能够解决输出问题，这个方法是专门为了本地话提供的一个调试方法，只要重写， 不需要导入头文件，程序中所有的 NSLog 数组的方法，都会被替代。NSArray *localeArray = @[@"hello", @"你好", @"欢迎"]; NSLog(@"%@", localeArray);
- 效果，使用前后对比
