封装读取Document temp一句代码搞定

因为项目中经常需要用到数据的存储.自己写着麻烦.就简单的封装了下.大神不喜勿喷.废话不多说直接上代码

.H文件的声明

#import@interface NSString (sandBox)

//chche目录

- (instancetype)appendCache;

//Document目录

- (instancetype)appendDocument;

//Temp目录

- (instancetype)appendTemp;

.M文件实现

#import "NSString+sandBox.h"

@implementation NSString (sandBox)

- (instancetype)appendCache

{

return [[NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) lastObject] stringByAppendingPathComponent:[self lastPathComponent]];

}

//Document目录

- (instancetype)appendDocument

{

return [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject] stringByAppendingPathComponent:[self lastPathComponent]];

}

//Temp目录

- (instancetype)appendTemp

{

return [NSTemporaryDirectory() stringByAppendingPathComponent:[self lastPathComponent]];

}

把他们封装成NSString分类 这样调用起来就可以一句话搞定.希望能对大家有所帮助.
