[英]Disabling the detail view controller in a split view controller on the iPad in iOS 5
[英]How to select default item in detail view for iPad? (in Split View Controller)
我正在使用拆分視圖控制器。 對於 iPad,當應用程序啟動時,我想在主視圖控制器的第一項中選擇。 那么我如何在 Swift 中做到這一點呢? 謝謝!
我解決了這個問題。 我寫信是為了在未來幫助他人。
func viewDidLoad() {
//..
let initialIndexPath = NSIndexPath(forRow: 0, inSection: 0)
self.tableView.selectRowAtIndexPath(initialIndexPath, animated: true, scrollPosition:UITableViewScrollPosition.None)
if UIDevice.currentDevice().userInterfaceIdiom == .Pad {
self.performSegueWithIdentifier("ShowDetail", sender: initialIndexPath)
}
}
func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if segue.identifier == "ShowDetail" {
if sender!.isKindOfClass(UITableViewCell) {
if let indexPath = self.tableView.indexPathForCell(sender as! UITableViewCell) {
// Get row from selected row in tableview
}
} else if sender!.isKindOfClass(NSIndexPath) {
let tableCell = self.tableView.cellForRowAtIndexPath(sender as! NSIndexPath)
let indexPath = self.tableView.indexPathForCell(tableCell!)
// Get row from sender, which is an NSIndexPath
}
}
}
轉換為 Swift 3:
let initialIndexPath = IndexPath(row: 0, section: 0)
self.tableView.selectRow(at: initialIndexPath, animated: true, scrollPosition: UITableViewScrollPosition.none)
if UIDevice.current.userInterfaceIdiom == .pad {
self.performSegue(withIdentifier: Constants.Segues.showDetail, sender: initialIndexPath)
}
修復自動錯誤后轉換為 Swift 5
let initialIndexPath = NSIndexPath(row: 0, section: 0)
self.tableView.selectRow(at: initialIndexPath as IndexPath, animated: true, scrollPosition:UITableView.ScrollPosition.none)
if UIDevice.current.userInterfaceIdiom == .pad {
self.performSegue(withIdentifier: "ShowDetail", sender: initialIndexPath)
}
