uisearchbar

问题 I have hidden my navigation bar in my table view controller, but after selecting the search bar and then dismissing it with Cancel it shows the navigation bar again. I tried -(void)searchBarTextDidEndEditing:(UISearchBar *)searchBar { self.navigationController.navigationBar.hidden = YES; } But it did not work, it did hide the navigation bar from the detail view though, but that was not desired. In storyboard I have a tabBarController --> navigationController --> tableView --> detailview.

问题 I am new to Swift and wondering if there any possibilities to place UIsearchcontroller in navgationtitle and to hide and unhide uisearchcontroller by button that is located as navigationRightItem.

问题 I (just like everyone else here) am running into the same Status Bar overlap issue that everyone else is, with a little twist, and that is why I opening a new question about this. There seems to be some mechanism that lets the UISearchBar know where to position it self, which is totally out of whack. jaredsinclair answer here (iOS 7 status bar back to iOS 6 default style in iPhone app?) , explains in great detail how the Apple Engineers allow us to introduce logic to our application in order

问题 I have a tableView with a searchBar inside the table header. Everything is working well except when I scroll down the rows, the search bar disappear. How can I make it fixed? 回答1: There is no a way to maintain the header of a tableView fixed, but an useful approach when you need a unique header, could be to use UIViewController instead of UITableViewController, and set the header (UIView that contains searchBar) above the tableView. 来源： https://stackoverflow.com/questions/45147582/swift-fixed
