ios - Tableview 不使用 Objective-c 显示 NewsFeed

Question

新闻源未显示在 TableView Controller 中。与新闻源 View Controller 链接的BuyerSocialPage 具有 BuyerSocialPage.h 文件

@interface BuyerSocialPage : UIViewController <UITableViewDataSource,UITableViewDelegate>

@end

@implementation BuyerSocialPage

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    self.tableView.delegate=self;
    UINib * firstNib = [UINib nibWithNibName:@"BSPFirstCell" bundle:nil];
    [self.tableView registerNib:firstNib forCellReuseIdentifier:@"BSPFirstCell"];
    UINib * secondNib = [UINib nibWithNibName:@"BSPSecondCell" bundle:nil];
    [self.tableView registerNib:secondNib forCellReuseIdentifier:@"BSPSecondCell"];
    UINib * thirdNib = [UINib nibWithNibName:@"BSPThirdCell" bundle:nil];
    [self.tableView registerNib:thirdNib forCellReuseIdentifier:@"BSPThirdCell"];
    UINib * fourthNib = [UINib nibWithNibName:@"BSPFourthCell" bundle:nil];
    [self.tableView registerNib:fourthNib forCellReuseIdentifier:@"BSPFourthCell"];
    self.view.backgroundColor = [UIColor whiteColor];
    [self getBuyerSocialPage];

    if (self.revealViewController) {
        [_sidebarButton addTarget:self.revealViewController action:@selector(revealToggle:) forControlEvents:UIControlEventTouchUpInside];
        [self.view addGestureRecognizer:self.revealViewController.panGestureRecognizer];
    }


}
-(void)getBuyerSocialPage {

    }

}

-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{
    int row = (int)indexPath.row;
    if (row == 0) {

        return 324;
    }
    else if (row == 1)
    {
        return 152;
    }
    else if (row == 2)
    {
        return 152;
    }
    else
    {
        return 152;
    }
}

登录后您将看到主屏幕。从顶部的侧面菜单栏中选择“新闻源”，它应该显示新闻源。但它没有显示新闻源。Api 在 postman 上正确运行

如何在表格 View 中获取新闻源？

Answer 1

您的网址&pageno=1中缺少页码。

您的网址如下所示: http://api.shoclef.com/api/NewsFeed?user_id=1164

应该是这样的: http://api.shoclef.com/api/NewsFeed?user_id=1164&pageno=1

在 API Manager 类中尝试此操作。对我来说工作得很好。

 NSString * url = [NSString stringWithFormat:@"%@NewsFeed?user_id=%I&pageno=1",API_BASE_URL,userID];

图像更新

在 NewsFeedNew 类 的 cellForRowAtIndexPath 函数中更新此代码

NSString *strUrl = [self.images objectAtIndex:indexPath.row].image;
    strUrl = [strUrl stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLFragmentAllowedCharacterSet]];
    [cell.image sd_setImageWithURL:[NSURL URLWithString:strUrl]];
