Question

我正在开发instragramm类型的应用程序，当用户点击像按钮我想在like arry中添加用户名所以我在带有数组的字典中有一本字典。我正在尝试添加到like数组中的数组。

    {
    caption = "Shakira Shakira...";
    comments =         (
    );
    "display_name" = Shakira;
    ext = "<null>";
    "image_id" = 53;
    likes =         (
    );
    "post_type" = i;
    "total_comments" = 0;
    "total_likes" = 0;
    "upload_dt" = 3wk;
    "user_id" = 7;
    "user_liked" = 0;
},
    {
    caption = "Addicted to Shakira???";
    comments =         (
                    {
            comment = "love your profile :)";
            "display_name" = Rihanna;
            "user_id" = 5;
        },
                    {
            comment = "You are my favorite celebrity on Follow Me.";
            "display_name" = Pitbull;
            "user_id" = 4;
        },
                    {
            comment = "Looking Good!";
            "display_name" = "Justin Bieber";
            "user_id" = 2;
        }
    );
    "display_name" = Shakira;
    ext = "<null>";
    "image_id" = 52;
    likes =         (
                    {
            "display_name" = "Justin Bieber";
            "user_id" = 2;
        },
                    {
            "display_name" = Rihanna;
            "user_id" = 5;
        },
                    {
            "display_name" = Pitbull;
            "user_id" = 4;
        }
    );
    "post_type" = i;
    "total_comments" = 3;
    "total_likes" = 3;
    "upload_dt" = 2mth;
    "user_id" = 7;
    "user_liked" = 0;
},

我想添加display_name和user_id

Answer 1

NSMutableArray *mutearr = [NSMutableArray arrayWithArray:array];

这里的数组是NSArray，mutarr是NSMutablearray

Answer 2

您可以使用addObjectsFromArray：来自NSMutableArray类

NSArray *animal = [[NSArray alloc]initWithObjects:@"Lion",@"Tiger",@"Dog",@"Cat",@"Sheep",@"Wolf", nil];
NSArray *color = [[NSArray alloc]initWithObjects:@"Blue",@"Red",@"Yellow",@"Green",@"Black", nil];

NSMutableArray *all = [[NSMutableArray alloc] init];
[all addObjectsFromArray:animal];
[all addObjectsFromArray:color];

在nsmutablearray中添加数组
