iOS－plist的保存和读取

两个按钮

// 当点点击保存的时候调用
- (IBAction)save:(id)sender {
    // 获取沙盒的根路径
//    NSString *home = NSHomeDirectory();

    // 拼接Documents路径
//    NSString *docPath = [home stringByAppendingString:@"/Documents"];
//    NSString *docPath = [home stringByAppendingPathComponent:@"Documents"];

    /**
     *  NSDocumentDirectory : 查找Documents文件夹
        NSUserDomainMask ： 在用户的应用程序下查找
     YES 把路径展开 NO 当前应用的根路径 == ~
     NO  ~/Documents

     */
    NSString *docPath =  NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)[0];
    NSLog(@"%@",docPath);

    // 拼接文件路径
    NSString *filePath = [docPath stringByAppendingPathComponent:@"data.plist"];

    // 只有具备writeToFile:的对象才能使用plist存储，NSArray
    NSArray *array = @[@1,@2,@"123"];

    [array writeToFile:filePath atomically:YES];

//    NSLog(@"%@",docPath);

}

//当点击读取的时候调用
- (IBAction)read:(id)sender {
    NSString *docPath =  NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)[0];
    NSLog(@"%@",docPath);

    // 拼接文件路径
    NSString *filePath = [docPath stringByAppendingPathComponent:@"data.plist"];

   NSArray *data = [NSArray arrayWithContentsOfFile:filePath];
    NSLog(@"%@",data);
