Iphone NSMutableDictionary使用键在Plist中设置数据

我有以下代码

    for (int j= 0; j<data.count; j++){
        NSString *thedata = [data objectAtIndex:j];
        NSMutableDictionary * booksList = [NSMutableDictionary dictionary];
        if(j==0){
            [booksList setValue:[NSString stringWithFormat:@"%@",thedata]  forKey:@"name"];

        }
        if(j==1){
            [booksList setValue:[NSString stringWithFormat:@"%@",thedata]  forKey:@"author"];

        }

        [plistDict setObject:booksList forKey:@"Categories"];
     [plistDict writeToFile:pListPath atomically: YES];
    }

那么谁能帮上什么忙呢？

您正在为循环的每个迭代重新创建一个空白字典。移动

NSMutableDictionary * booksList = [NSMutableDictionary dictionary];

---

在for语句开始之前。如果我理解正确，将write和setobject移动到循环结束后

谢谢。。有时候，一个人为了这么小的事情工作了一整晚之后，需要和他一起看一眼：）再次感谢

NSMutableDictionary * booksList = [NSMutableDictionary dictionary];
