推荐答案

搜索栏实际上并没有在俯卧撑动画中移动。而是在导航栏上升时保持原位，从而用它拉动视图的其余部分。您应该可以通过注册为其委托（UISearchBarDelegate）并响应这些调用来手动移动搜索栏。

The searchbar doesn't actually move in the 'push-up' animation. Rather it stays in place while the navbar goes up, thus pulling the rest of the view with it. You should be able to move the search bar manually in code by registering as its delegate (UISearchBarDelegate) and responding to these calls.

#pragma mark - UISearchBarDelegate Methods
- (BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar {
    //move the search bar up to the correct location eg
    [UIView animateWithDuration:.4
                 animations:^{ 
                     searchBar.frame = CGRectMake(searchBar.frame.origin.x,
                                                  0,
                                                  searchBar.frame.size.width,
                                                  searchBar.frame.size.height);
                 } 
                 completion:^(BOOL finished){
                     //whatever else you may need to do
                 }];
}

- (BOOL)searchBarShouldEndEditing:(UISearchBar *)searchBar {
    //move the search bar down to the correct location eg
    [UIView animateWithDuration:.4
                 animations:^{ 
                     searchBar.frame = CGRectMake(searchBar.frame.origin.x,
                                                  /*SearchBar original Y*/,
                                                  searchBar.frame.size.width,
                                                  searchBar.frame.size.height);
                 } 
                 completion:^(BOOL finished){
                     //whatever else you may need to do
                 }];
}
