plist读写

NSString *plistPath = [[NSBundle mainBundle] pathForResource:@"plistdemo" ofType:@"plist"];
    NSMutableDictionary *data = [[NSMutableDictionary alloc] initWithContentsOfFile:plistPath];
    NSLog(@"date = %@", data);//直接打印数据。
    
    
    
    //添加一项内容
    [data setObject:@"some content" forKey:@"d_key"];
    [data setObject:@"AAA" forKey:@"c_key"];
    
    //获取应用程序沙盒的Documents目录
    NSArray *paths=NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES);
    for(int i=0;i<[paths count];i++)
    {
        NSString *plistPath1 = [paths objectAtIndex:i];
        //得到完整的文件名
        NSString *filename=[plistPath1 stringByAppendingPathComponent:@"test.plist"];
        NSLog(@"%@",plistPath);
        //输入写入
        [data writeToFile:filename atomically:YES];
    
        //那怎么证明我的数据写入了呢？读出来看看
        NSMutableDictionary *data1 = [[NSMutableDictionary alloc] initWithContentsOfFile:filename];
        NSLog(@"date = %@", data1);
    }
