    //获取文件路径，路径名不可随意取，不可以光使用文件名作为路径    NSArray*paths=NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask,YES);        NSString*directory=[paths objectAtIndex:0];        NSString*path=[NSString stringWithFormat:@"%@/data.txt",directory ];                NSArray* arr=@[@"abc",@"def",@"xxx"];    [arr writeToFile:path atomically:YES];        NSArray*dats= [NSArray arrayWithContentsOfFile:path];    NSLog(@"读取Array文件内容 ---- ");    for (NSString *s in dats) {       NSLog(@"%@",s);    }            NSDictionary*map=@{@"k1":@"v1",@"k2":@"v2"};    [map writeToFile:path atomically:YES];        NSDictionary* datamap=[NSDictionary dictionaryWithContentsOfFile:path];        NSLog(@"读取Directory文件内容 ---- ");    NSLog(@"%@",datamap);            [@"abc-str-xxx" writeToFile:path atomically:YES encoding:NSUTF8StringEncoding error:nil];    NSString*s=[NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:nil];    NSLog(@"读取NSString文件内容 ---- %@",s);
