當(dāng)我們push時(shí) searchbar 會(huì)閃爍出現(xiàn)（就延遲了出現(xiàn)）
override func viewDidLoad() { navigationController?.navigationBarHidden = true//去除UISeachbar 的白邊閃爍bug（在super前調(diào)用） super.viewDidLoad() } override func viewWillAppear(animated: Bool) { navigationController?.navigationBarHidden = false super.viewWillAppear(animated) searchBar.becomeFirstResponder() }
