问题描述
在我的UITableViewController的初始加载中,第一行被隐藏在导航后面,但是如果我推送到另一个视图并返回到这个UITableViewController,它将被正确加载并且第一行不会被遮挡。我无法弄明白这一点。
On the initial load of my UITableViewController the first row gets hidden behind the navigation, but if I push to another view and return to this UITableViewController it is loaded correctly and the first row isn't obscured. I can not figure this one out.
这是表的初始加载的屏幕截图,右边的那个是我从其中一个视图返回之后是通过点击一行推的
Here's a screen shot of the initial load of the table and the one on the right is after I return from one of the views that was pushed by clicking a row
这是我的控制器代码:
class AccountInfoTableViewController: UITableViewController{
var delegate: AccountInfoTableViewDelegate?
override func viewDidLoad() {
super.viewDidLoad()
self.navigationController?.topViewController.title = "Account Info"
self.automaticallyAdjustsScrollViewInsets = true
println("NAV BAR HEIGHT \(self.navigationController?.navigationBar.frame.size.height)") // 44.0
// prints NAV BAR HEIGHT 44.0
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
override func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
return 70
}
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
if let cell = tableView.cellForRowAtIndexPath(indexPath){
delegate?.accountInfoTableRowClicked(cell.textLabel!.text!)
}
}
}
可能重要注意:
此UITableViewController用于标签栏控制器
This UITableViewController is used in a tab bar controller

推荐答案
看着你的另外一个问题,我想知道在UINavigationController中嵌入UITabBarController是否也是同样的问题。如果是这种情况,Just再次回顾,控制器层次结构应如下所示:
looking at your other question, I'm wondering if it's the same issue with having the UITabBarController embedded within a UINavigationController. If that's the case, the Just to recap again, the controller hierarchy should be as follows:
第一个UINavigationController - >第一个UITableViewController
第二个UINavigationController - >第二个UITableViewController
最后,上面的两个UINavigationControllers都添加到了UITabBarController的viewControllers数组中。
First UINavigationController -> First UITableViewControllerSecond UINavigationController -> Second UITableViewControllerFinally, both of the above UINavigationControllers added to the UITabBarController's viewControllers array.
