数据未出现在UIView上

Question

我有一个标题UIView，我试图将JSON数据加载到，但是根本没有显示任何信息，如下所示：

以下是我加载标题视图的方法：

- (ForeignInstagramViewHeader *)header {
    if (!_header) {
        _header = [[ForeignInstagramViewHeader alloc] initWithFrame:CGRectMake(0, 0, 320, 150) withUserData:self.instaUser];
        NSString *userID = self.instagramData[@"user"][@"id"];
        [self getInstaDataWithUserID:userID];
        _header.instaUser = self.instaUser;
    }
    return _header;
}

以下是获取Instagram数据的方法：

- (void)getInstaDataWithUserID:(NSString *)user {
    NSString *path = [NSString stringWithFormat:@"users/%@", user];

     [[InstagramClient sharedClient] getPath:path parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
     NSLog(@"%@",responseObject);
         self.instaUser = [[InstagramUser alloc] init];
         [self.instaUser setBio:responseObject[@"data"][@"bio"]];
         self.instaUser.followed_by = responseObject[@"data"][@"counts"][@"followed_by"];
         self.instaUser.follows = responseObject[@"data"][@"counts"][@"follows"];
         self.instaUser.media = responseObject[@"data"][@"counts"][@"media"];
         self.instaUser.full_name = responseObject[@"data"][@"full_name"];
         self.instaUser.idvalue = responseObject[@"data"][@"id"];
         self.instaUser.profile_picture = responseObject[@"data"][@"profile_picture"];
         self.instaUser.username = responseObject[@"data"][@"username"];
         self.instaUser.website = responseObject[@"data"][@"website"];

    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
      NSLog(@"Error: %@", error);
     }];
}

这是我的标题View Class.h：

@interface ForeignInstagramViewHeader : UIView

@property (nonatomic, strong) UIImageView *profilePic;
@property (nonatomic, strong) UILabel * nameString;
@property (nonatomic, strong) UILabel * postCount;
@property (nonatomic, strong) UILabel * postString;
@property (nonatomic, strong) UILabel * followerCount;
@property (nonatomic, strong) UILabel * followerString;
@property (nonatomic, strong) UILabel * followingCount;
@property (nonatomic, strong) UILabel * followingString;
@property (nonatomic, strong) UILabel * bioString;
@property (nonatomic, strong) UILabel * websiteString;

@property InstagramUser *instaUser;

- (id)initWithFrame:(CGRect)frame withUserData:(InstagramUser *)instagram;
@end

Answer 1

在ForeignInstagramViewHeader类中添加一个方法来更新用户详细信息，例如

- (void)updateWithUserDetails:(InstagramUser *)user {

    self.instaUser = user;
    // set values from user to lable's and other UI elements.
}

和标题方法将是

- (ForeignInstagramViewHeader *)header {
    if (!_header) {
        _header = [[ForeignInstagramViewHeader alloc] initWithFrame:CGRectMake(0, 0, 320, 150) withUserData:self.instaUser];
    }
    return _header;
}

并在getInstaDataWithUserID:方法中，

- (void)getInstaDataWithUserID:(NSString *)user {
    NSString *path = [NSString stringWithFormat:@"users/%@", user];

     [[InstagramClient sharedClient] getPath:path parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
     NSLog(@"%@",responseObject);
         self.instaUser = [[InstagramUser alloc] init];
         [self.instaUser setBio:responseObject[@"data"][@"bio"]];
         self.instaUser.followed_by = responseObject[@"data"][@"counts"][@"followed_by"];
         self.instaUser.follows = responseObject[@"data"][@"counts"][@"follows"];
         self.instaUser.media = responseObject[@"data"][@"counts"][@"media"];
         self.instaUser.full_name = responseObject[@"data"][@"full_name"];
         self.instaUser.idvalue = responseObject[@"data"][@"id"];
         self.instaUser.profile_picture = responseObject[@"data"][@"profile_picture"];
         self.instaUser.username = responseObject[@"data"][@"username"];
         self.instaUser.website = responseObject[@"data"][@"website"];

         //UPDATE
         dispatch_async(dispatch_get_main_queue(), ^{
             [[self header] updateWithUserDetails:self.instaUser];
         });
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
      NSLog(@"Error: %@", error);
     }];
}
