防止点击时UISearchBar缩进

Question

In my viewDidLoad , I programmatically create a search bar. When the search field is tapped, the search bar indents to the right. Why is this happening and how do I prevent it from doing so? I am not using autolayout.

- (void)createSearchBar {
    self.searchController = [[UISearchController alloc] initWithSearchResultsController:nil];
    self.searchController.searchResultsUpdater = self;
    self.searchController.searchBar.delegate = self;
    [self.searchController.searchBar sizeToFit];
    self.searchController.dimsBackgroundDuringPresentation = NO;
    self.searchController.hidesNavigationBarDuringPresentation = NO;
    self.definesPresentationContext = YES;
    self.edgesForExtendedLayout = UIRectEdgeNone;
}

您可以尝试使用positionAdjustmentForSearchBarIcon:或setPositionAdjustment:forSearchBarIcon:委托调用中对搜索setPositionAdjustment:forSearchBarIcon:消息调用： searchBarTextDidBeginEditing:
