一,Usefulcategory说明
部分category收集于blog,实际项目等等中. 本人对其重新”筛选,整理,优化,封装”.每个分类都有详细的解释和使用说明.很有用! Github地址: https://github.com/LuochuanAD/UsefulCategory * **二,Usefulcategory使用
- NSObject(Safe) 导入到项目中, 此分类需在MRC环境下使用,需添加-fno-objc-arc. 防止崩溃,提高代码的健壮性.强烈推荐(因为我自己写的没有它好,这个分类是用的别人). 该分类包含NSString,NSMutableString,NSArray,NSMutableArray,NSDictionary,NSMutableDictionary, NSAttributedString,NSMutableAttributedString,NSSet,NSMutableSet,NSOrderedSet, NSMutableOrderedSet,NSUserDefaults,NSCache.
