Visual Studio和CMS？(Visual Studio and CMS?)

 好的，所以您可能正在将这些数据下载到JSON字典或数组中，因此您最初可以将表和集合视图设置为没有这样的内容： 
 
class ViewController : UIViewController, UITableViewDataSource, UITableViewDelegate, UICollectionViewDataSource, UICollectionViewDelegate {
// note that I would recommend separating these into extensions on ViewController

    var htmlResponses = []()

    override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

        return htmlResponses.count
        // htmlResponses is empty at this point
    }

    override func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {

        return htmlResponses.count
        // htmlResponses is empty at this point
    }
}
 
 然后，一旦您的数据进入，只需使用所述数据填充htmlResponses数组，并分别为表视图和集合视图调用tableView.reloadData()和collectionView.reloadData() 。 
 
 即使您不使用数组来存储数据，概念也是一样的。 使用空元素填充视图，并在知道数据已从服务器到达后重新加载它们。 

Ok, so you're probably downloading this data into a JSON dictionary or into an array, so you could initially set the table and collection views to have no content like so:
 
class ViewController : UIViewController, UITableViewDataSource, UITableViewDelegate, UICollectionViewDataSource, UICollectionViewDelegate {
// note that I would recommend separating these into extensions on ViewController

    var htmlResponses = []()

    override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

        return htmlResponses.count
        // htmlResponses is empty at this point
    }

    override func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {

        return htmlResponses.count
        // htmlResponses is empty at this point
    }
}
 
Then, once your data comes in, simply populate the htmlResponses array with said data and call tableView.reloadData() and collectionView.reloadData() for your table views and collection view respectively.
 
Even if you do not use arrays to store your data, the concept is the same. Use empty elements to populate your views and reload them once you know the data has arrived from the server.
