I have a UITableView in a UIViewController...
I'm using a UISearchController to give me a search bar and setting this to the table's header view. I'm also using sections in the UITableView. My problem is, on first presentation, the table header collides with the first cell...
After search bar has been activated once and then dismissed, the table renders as I expect it to...
The code code looks like...
override func viewDidLoad() {
super.viewDidLoad()
self.table.dataSource = self
self.table.delegate = self
self.table.tableHeaderView = self.searchController.searchBar
self.definesPresentationContext = true
self.searchController.searchBar.sizeToFit()
self.searchController.dimsBackgroundDuringPresentation = false
self.searchController.searchResultsUpdater = self
self.searchController.delegate = self
}
... and this style works fine in other tables which do not have sections.
For future users, setting the table rows to have automatic height fixed this problem...
self.table.estimatedRowHeight = 44
self.table.rowHeight = UITableViewAutomaticDimension

As shown in the [figure]
when I scroll down to the end appears a large block with nothing, How to remove this and scroll the scroll only until the end of UiTableView content?
the following images describe the configuration of my uitableview in the storyboard:storyboar_one, storyboard_two, storyboard_three
this my viewDidLoad Method:
override func viewDidLoad() {
super.viewDidLoad();
tableView.dataSource = self
tableView.delegate = self
let nib: UINib = UINib(nibName: "ObrigacaoTableViewCell", bundle: nil)
tableView.register(nib, forCellReuseIdentifier: "reuseIdentifier")
tableView.rowHeight = UITableViewAutomaticDimension
tableView.estimatedRowHeight = 150
}
Try self.tableView.tableFooterView = [[UIView alloc] initWithFrame:CGRectZero];
Because the table thinks there is a footer to show, it doesn't display any cells beyond those you explicitly asked for therefore it shows up as a blank space.
Also make sure the bottom edge inset of UITableView is 0
To remove blank cells in the table keep the below code in viewDidLoad() method after estimatedHeight,
tableView.tableFooterView = UIView(frame: .zero)
Remove empty cells in UITableView
self.tableView.tableFooterView = UIView()
Here is an image of the issue:
As you can see the text is highlighted (select all) was pressed, however, as you can see the text isn't actually highlighted.
I don't think it matters but this search bar isn't searching local data it's using Algolia.
My class in implementing UISearchBarDelegate the search bar is created in code not interface builder and the only method implemented is searchBarSearchButtonClicked which I can include code for, but I don't think it's needed. Additionally, this VC is inside a navigation controller
Code:
override func viewDidLoad() {
super.viewDidLoad()
self.tableView.rowHeight = UITableViewAutomaticDimension
self.tableView.estimatedRowHeight = 135;
searchBar.placeholder = "Search"
searchBar.delegate = self
navigationItem.titleView = searchBar
tableView.delegate = self
tableView.dataSource = self
self.edgesForExtendedLayout = UIRectEdge()
self.extendedLayoutIncludesOpaqueBars = false
self.automaticallyAdjustsScrollViewInsets = false
}
The effect comes from a white selection color. You can change the selection color by assigning a color to the property tintColor of UISearchBar, or over the appearance for all search bars:
UISearchBar.appearance().tintColor = .black
SubViewController (a child of ViewController and IndicatorInfoProvider) is added using MainViewController (a child of ButtonBarPagerTabStripViewController) with NavigationBar added.
Padding does not occur even if you tap tabbutton, padding occurs on top when swipe.
animated gif 👇
override func viewDidLoad() {
super.viewDidLoad()
print("viewDidLoad")
// Do any additional setup after loading the view.
self.view.backgroundColor = UIColor.clear
//tableview
self.tableView.delegate = self
self.tableView.dataSource = self
self.tableView.backgroundView = nil
self.tableView.backgroundColor = UIColor.clear
//動的に高さを変更
self.tableView.estimatedRowHeight = 155
self.tableView.rowHeight = UITableViewAutomaticDimension
//indicator
self.tableView.showIndicator()
//loaddata
loadData(page:0)
}
I've encountered the same problem.
Open your storyboard and select the MainViewController. In the Attribute Inspector deselect the checkbox 'Adjust scroll view insets'
Are you using a UITableViewController as a childViewController? This issue seems to happen in this case.
To fix this, you should be setting automaticallyAdjustsScrollViewInsets = false and also having as childViewControllers only UIViewControllers with a UITableView inside, instead of UITableViewController.

I want to remove the line between 2 views. The line that separates 2 UITableViewCells:
I declared table view as following:
self.tableView = [[UITableView alloc] initWithFrame:CGRectZero style:UITableViewStylePlain];
self.tableView.delegate = self;
self.tableView.dataSource = self;
self.tableView.keyboardDismissMode = UIScrollViewKeyboardDismissModeOnDrag;
self.tableView.scrollEnabled = NO;
self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
self.tableView.estimatedRowHeight = 85.0;
self.tableView.rowHeight = UITableViewAutomaticDimension;
So i actually wrote - self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
Why does it still exist?
Objective-C :
[self.tableView setSeparatorStyle:UITableViewCellSeparatorStyleNone];
Swift:
self.tableView.separatorStyle = UITableViewCellSeparatorStyle.None
Swift 5.0 renamed it in :
self.tableView.separatorStyle = UITableViewCell.SeparatorStyle.none
Apply the line in viewDidLoad() method.
If you want to do it from nib file, set the tableView's Separator property to None
For Swift 4:
tableView.separatorStyle = .none
For Swift 5 :
viewDidLoad(){
tableView.separatorStyle = UITableViewCell.SeparatorStyle.none
}
For Objective-C :
[self.tableView setSeparatorStyle:UITableViewCellSeparatorStyleNone];
or you can use interface builder instead
For more information
SeparatorStyle
Hide tableView separators using UI
Here you select TableView 'Separator' property as 'None'.

You can use the following code because it will not remove the line separators of the sections.:
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
// Your code here //
cell.separatorInset = UIEdgeInsetsMake(0.f, [UIScreen mainScreen].bounds.size.width, 0.f, 0.f);
}
My problem was when I add tableView trough code and I have separate func to show tableview and add it on mainView (slide from bottom) I needed to add this
tableView.separatorStyle = .none
in that func where tableView is added on mainView and constraint it.
In Swift 4.2 you can conveniently use dot notation on a tableView's separatorStyle. Like so:
tableView.separatorStyle = .none
As #gonsee point out:
"Setting separatorStyle seems to have no effect unless the table view is in the window's view hierarchy. If you have a table view on some UIView subclass"
You should set the seperatorStyle in viewDidAppear if you your table in UIView.
override func viewDidAppear(_ animated: Bool) {
self.contentView.documentTableView.separatorStyle = .none
}
In viewDidLoad add tableView.separatorStyle = .none
Example:
override func viewDidLoad() {
super.viewDidLoad()
...
self.tableView.separatorStyle = .none // <---
...
}
you can archive these things in different ways
you can also use this one line of code in viewDidLoad()
override func viewDidLoad() {
super.viewDidLoad()
tableView.tableFooterView = UIView()
}
You can do it on a storyboard
set the code in viewDidLoad()
override func viewDidLoad() {
super.viewDidLoad()
tableView.separatorStyle = .none
}
add this line
tableView.separatorStyle = .none
I'm trying to add an UISearchController on top of an UITableView (not in it's header) and I created a placeholder view for it in storyboard with a height constraint of 44.
In the normal state it all works fine but when I add some scope button, those overlap my first UITableViewCell and I'm unable to find a solution for this. I tried to re-set the height constraint of my placeholder view but I don't find the right functions to place it and couldn't find the "right" animation so it still looks nice.
My UISearchController looks like this:
override func viewDidLoad() {
super.viewDidLoad()
self.searchController.searchResultsUpdater = self
self.searchController.hidesNavigationBarDuringPresentation = true
self.searchController.dimsBackgroundDuringPresentation = false
self.searchController.searchBar.searchBarStyle = .Default
self.searchController.searchBar.tintColor = UIColor.blueColor()
self.searchController.searchBar.delegate = self
self.searchController.searchBar.scopeButtonTitles = ["Test1", "Test2"]
self.searchController.searchBar.sizeToFit()
self.searchBarViewWrapper.addSubview(self.searchController.searchBar)
}
Here is a solution I found worked well. Add searchBar to tableHeaderView instead of your wrapper view:
searchController.searchBar.scopeButtonTitles = ["Test1", "Test2"]
tableView.tableHeaderView = searchController.searchBar
