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)

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.

- UITableView

    CustomAnimationTypeShaKe,       //抖动动画
    CustomAnimationTypeOverTurn,    //翻转动画
    CustomAnimationTypeToTop,       //从下往上
    CustomAnimationTypeSpringList,  //从上往下弹动动画
    CustomAnimationTypeShrinkToTop, //从下往上挤向顶部
    CustomAnimationTypeLayDown,     //从上往下展开
    CustomAnimationTypeRote,        //翻转动画
