我的应用程序目前有一个搜索栏,并生成一个从搜索栏下拉结果的持有人视图。然而,ResultContainerView在我的其他视图后面。我想知道如何把那个搜索栏容器视图到UIView层次结构的顶部。我尝试使用[super bringSubviewToFront:_searchResultsHolderView];
,但没有工作。这是我的方法,当搜索栏被点击。
- (void)_expandSearchResults
{
CCLogVerbose (@"");
_searchResultsHolderView.alpha = 0.0;
_searchResultsHolderView.hidden = NO;
[_searchResultsHolderView setFrameHeight:10];
[UIView beginAnimations:@"expandSearchResults" context:nil];
[UIView setAnimationDuration:kAnimationDuration_SearchResults];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:@selector (searchAnimationDidStop:finished:context:)];
_searchResultsHolderView.alpha = 1.0;
[_searchResultsHolderView setFrameHeight:_searchResultsHt];
[super bringSubviewToFront:_searchResultsHolderView];
[UIView commitAnimations]; // start animation
}
这是我的reloadData方法
- (void)_reloadSearchResults:(NSString *)searchS
{
CCLogVerbose (@"");
if ([searchS length] == 0) {
_searchResults = nil;
[_searchResultsTableView reloadData];
return;
}
NSAssert (self.patientService != nil, @"The Patient Service is invalid");
[self.patientService searchPatients:searchS
expandType:AllPatientExpansions
success:^(NSArray *list) {
_searchResults = list;
[_searchResultsTableView reloadData];
}
failure:^(NSError *error) {
CCLogDebug (@"Failed: %@", error);
}];
}
[self.superview bringSubviewToFront:self];
[self bringSubviewToFront:_searchResultsHolderView];
首先,您需要将self
带到堆栈的顶部。之后,你可以呼叫bringSubViewToFront
,并把你的_searchResultsHolderView
带到前面。
