[iOS功能]- 对沙盒目录操作

NSFileManager *defauleManager = [NSFileManager defaultManager];
NSString *tempPath = NSTemporaryDirectory();
NSLog(@"%@",tempPath);
NSString *thePath = nil;

//创建一个目录：  在temp下创建 MyFoler目录
thePath = [NSString stringWithFormat:@"%@/MyFolder",tempPath];
[defauleManager createDirectoryAtPath:thePath withIntermediateDirectories:YES attributes:nil error:nil];

//写入一个文件  在 temp目录下
NSString *aStr = @"hello world";
thePath = [NSString stringWithFormat:@"%@hello.txt",tempPath];
[aStr writeToFile:thePath atomically:YES encoding:NSUTF8StringEncoding error:nil];

//显示目录内容
NSLog(@"temp目录内容：%@",[defauleManager contentsOfDirectoryAtPath:tempPath error:nil]);

//删除一个文件
NSString *deleteStr = @"delete Str";
thePath = [NSString stringWithFormat:@"%@delete.txt",tempPath];
[deleteStr writeToFile:thePath atomically:YES encoding:NSUTF8StringEncoding error:nil];
NSLog(@"temp目录内容：删除之前：%@",[defauleManager contentsOfDirectoryAtPath:tempPath error:nil]);
[defauleManager removeItemAtPath:thePath error:nil];
NSLog(@"temp目录内容：删除之后：%@",[defauleManager contentsOfDirectoryAtPath:tempPath error:nil]);

//删除一个目录：
thePath = [NSString stringWithFormat:@"%@/TestFoler",tempPath];
[defauleManager createDirectoryAtPath:thePath withIntermediateDirectories:YES attributes:nil error:nil];
NSLog(@"temp目录内容：%@",[defauleManager contentsOfDirectoryAtPath:tempPath error:nil]);
[defauleManager removeItemAtPath:thePath error:nil];
NSLog(@"temp目录内容：%@",[defauleManager contentsOfDirectoryAtPath:tempPath error:nil]);


//获取目录下的所有文件列表：
NSArray *fileList = [defauleManager contentsOfDirectoryAtPath:tempPath error:nil];
NSLog(@"%@",fileList);


//判断一个目录是否是文件夹
- (BOOL)fileExistsAtPath:(NSString *)path isDirectory:(BOOL *)isDirectory
