Question

我正在尝试在我的UILabel中显示字段'field_friendbio'。我应该怎么写这一行？ self.mapFriendData是一个NSMutableArray（数据从前一个控制器传递给self.mapFriendData）。

现在，我有：

·H

@property (nonatomic, strong) NSMutableArray *mapFriendData;

的.m

self.userBio.text = self.mapFriendData[@"field_friendbio"][@"und"][0][@"safe_value"];

但这只适用于NSDictionary。

数据输出：

  "field_friendbio" =         {
            und =             (
                                {
                    format = "<null>";
                    "safe_value" = "Hi my name is Blair. ";
                    value = "Hi my name is Blair. ";
                }
            );
        };

在我将其调用到UILabel之前，mapFriendData是：

THIS IS MAP FRIEND DATA (
        {
        body =         (
        );
        changed = 1462155513;
        cid = 0;
        comment = 2;
        "comment_count" = 0;
        created = 1462155513;
        data = "a:1:{s:7:\"overlay\";i:1;}";
        "field_address1" =         {
            und =             (
                                {
                    format = "<null>";
                    "safe_value" = "1275 This Street, LA, California";
                    value = "1275 This Street, LA, California";
                }
            );
        };
        "field_friendbio" =         {
            und =             (
                                {
                    format = "<null>";
                    "safe_value" = "Hi my name is Blair.";
                    value = "Hi my name is Blair.";
                }
            );
        };

正如你所说，它是一个数组，所以你需要提供你想要获得的字典的索引：

self.userBio.text = self.mapFriendData[0][@"field_friendbio"][@"und"][0][@"safe_value"];
                                       ^
                                    "index of your field_friendbio dict"

在UILabel中显示来自NSMutableArray的对象
