문제의 공간은 다음과 같이이다 :이상한 문제는, 내 UISearchController
이 searchbar
와 navbar
사이의 공간이 있습니다
:
을 그리고 Debug in Hierarchy
에서 테이블보기
navigationBar
자신에 의해 draged된다 6,
래퍼보기, 우리는
그리고 storyboard
에, 나는 tableView

나는 때가 먼저 vc
에 와서, 문제는 존재하지 않는다,하지만 난 searchBar
이 문제가 다시 올 것이다 클릭하면 어딘가 실수 인 경우, 내 코드를 의심 :
ATTEMPT - 2
나는 다음이 코드를 시도 할 경우 :
을func searchBarCancelButtonClicked(_ searchBar: UISearchBar) {
for item:NSLayoutConstraint in self.navbar.constraints {
if item.firstAttribute == NSLayoutAttribute.height {
item.constant = 44 // before is 64.
}
}
}
