文件操作之plist文件读取

有时开发需要把一些信息用plist保存在本地

存写：

    //获取应用沙盒的根目录

    NSString *homePath =NSHomeDirectory();

    

    //拼接路径

    NSString *docPath = [homePathstringByAppendingPathComponent:@"Documents"];

    

    //第二种方法

    docPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES)[0];

    

     NSString *filePath = [docPathstringByAppendingPathComponent:@"toutiao.plist"];

    

     NSArray *array =@[@"经纪人伟哥",@"经纪人洪",@"经纪人卓子",@"经纪人赵",@"经纪人白",@"孙宝强",@123,];

    

    //将数组存储到文件中

    [array writeToFile:filePathatomically:YES];

/Users/mfb/Library/Developer/CoreSimulator/Devices/2429D7D1-56FD-4BF4-BFBD-E61EE01B6D70/data/Containers/Data/Application/C53B4387-C51E-4636-8682-C21516DB1D5A/Documents/toutiao.plist

读取：

以存的类型为数组类型为例  

  //获取Documents目录

    NSString *docPath =NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES)[0];

    //还要指定存储文件的文件名称,仍然使用字符串拼接

    NSString *filePath = [docPathstringByAppendingPathComponent:@"toutiao.plist"];

    

    //使用一个数组来接受数据

    NSArray *array = [NSArrayarrayWithContentsOfFile:filePath];

Printing description of filePath:

/Users/mfb/Library/Developer/CoreSimulator/Devices/2429D7D1-56FD-4BF4-BFBD-E61EE01B6D70/data/Containers/Data/Application/C53B4387-C51E-4636-8682-C21516DB1D5A/Documents/toutiao.plist

Printing description of array:

<__NSCFArray 0x7fbeb1620d10>(

经纪人伟哥,

经纪人洪,

经纪人卓子,

经纪人赵,

经纪人白,

孙宝强,
