I want to develop iOS app in which i am using transparent Tababar,
and having UITableView on View when i run my app, because of Transperant Tababar my UITableView gets behind Tababar and i am unable to select last row of UITableView.
See: :
Thanks in advance.
simple adjust
table.contentInset = UIEdgeInsetsMake(0, 0, 200, 0); // try setting this value
hope this helps u :)
There are 2 possiblities:-
1). Firstly, You might have forgot to set datasource and delegate of the tableview to self.
2). The frame might be assigned incorrectly, i.e when we use both navigationbar and tab bar the height of tableView in iPhone4 is 367 and in iPhone5 it is 455.
It's not the tab bar alpha that's the issue. It't the frame of the UITableView. Either set the frame of the table to take the tab bar into account, or:
self.tableView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
Edit, potentially iOS7 having edge to edge layout. Try in viewDidLoad (self refers to the controller):
if ([self respondsToSelector:#selector(automaticallyAdjustsScrollViewInsets)]) {
self.automaticallyAdjustsScrollViewInsets = NO;
}

I have UIViewController that has a Navigation Bar. At run time, I am adding (on viewDidLoad) a UITable. The problem I have is an inconsistent behaviour of the UITableView y-position.
In viewDidLoad I set the UITableView frame to:
tableView = UITableView(frame: self.view.frame)
then:
self.view.addSubview(tableView)
The problem: on the odd occasion, and only on iphone 4s, the table is added underneath the NavigationBar resulting in the first row not being visible to the user (put another way: y-pos = 0).
If I try to set the y-pos to status bar height + nav bar height the table is always positioned too low (i.e. at the wrong y-pos)
Am I doing something wrong or have I stumbled upon random quirk of ios 9.2 & swift 2?
Hope this will help
Try following in controller's viewDidLoad Method :
self.automaticallyAdjustsScrollViewInsets = NO;
or You can disable it from Attribute Inspector as given in below image.
I have a tableview with frame size of(0, 65, 320, 503).When i navigate to another page then i come back it move down.
add the below line in your - (void)viewDidLoad method.
self.automaticallyAdjustsScrollViewInsets = NO;
hope it will fix your issue.
I hope you found a solution that worked for you. This was happening to me when using AutoLayout and UITableViews combined with the wonderful SWRevealViewController class. Long story short I wasted a bunch of time and eventually found this answer that worked for me:

I moved my UITableView to a lower position in the view hierarchy (by putting a dummy 1pt-thick spacer UIView between it and the Top Layout Guide), and now it behaves as expected.
Place this code in view will appear,
if ([self respondsToSelector:#selector(edgesForExtendedLayout)])
{
self.edgesForExtendedLayout = UIRectEdgeNone;
}
[self.navigationController.navigationBar setTranslucent:NO];
and also try removing auto layouts.
Hope this helps...
I think you need to set frame of tableview in viewWillAppear method again because some way in your code you r changing the frame so just set it in viewwillappear .
Try this in your viewWillAppear
[your_tableview removeFromSuperview];
[your_tableview setTranslatesAutoresizingMaskIntoConstraints:YES];
your_tableview.frame = CGRectMake(0, 65, 320, 503);
[self.view addSubview:your_tableview];
You could also try this if you don't want to use the header section
your_tableview.tableHeaderView = nil;
if you are using storyboard.
1>set Navigation bar's translucent property to NO. Adjust your subviews frame again because after setting its NO ,the subview will be adjusting with some new frames.
2> In viewDidLoad set the following
self.automaticallyAdjustsScrollViewInsets = NO;
3> its done.
I'm trying to position a TableView inside my ViewController view but leaving a 44 height gap between the bottom of the navigation bar and the top of the table. I then wanted to place a UITextField inside that gap to act as a stationary header. For some reason, the TableView has an empty white space above the start of the "Prototype Cells". Its just white space. Here is what it looks like in the storyboard.
When viewing the app display, this is what it looks like:
When scrolling the table, it goes all the way up to the correct place:
Try to look in the 'attribute inspector' (in the right menu) of the Participants ViewController.
Check for the option 'Extend Edges' and uncheck the 'Under Top Bars', and then relocate your tableview.
Another possible solution is to just uncheck the option 'Adjust Scroll View Insets'.
The reason is that when the viewController extends its edges, let's say under the top bar, the tableView's scrollView automatically adjusts its inset top, so that the content of the tableView will start exactly under the top bar. But in your case this is not needed, since your tableView itself starts under the bar.
Focus on the ViewController and got to the Attribute Inspector tab:
Try this one:
self.tableView.contentInset = UIEdgeInsetsMake(-65, 0, 0, 0)
Just add this in you ViewDidLoad method
self.automaticallyAdjustsScrollViewInsets = NO;
change your table view style from grouped to plain
You should not need to change the default setting for Extend Edges.
Looks like the real problem is a blank table header view in your storyboard. It's showing in the screenshot you provided of your storyboard, right below the Enter Name view and right above the Prototype Cells view. Delete it.
My issues is, I set tableHeaderView as new UIView like this
self.tableHeaderView = UIView(frame: .zero)
Remove this line, the issue is gone. Try this:
//self.tableHeaderView = UIView(frame: .zero)
This is the 2022, iOS 15 solution if anyone stumbles upon this.
if #available(iOS 15.0, *) {
UITableView.appearance().sectionHeaderTopPadding = CGFloat(0)
}
I just found a solution for this.
In my case, i was using TabBarViewController, A just uncheck the option 'Adjust Scroll View Insets'. Issues goes away.

For Objective-C folks, add this in your ViewDidLoad method.
[self.tableView setContentInset:UIEdgeInsetsMake(-20, 0, 0, 0)];
Im trying port my app to iOS7, but my custom TableViewController is showing the last row (cell) under the TabBar :(
Im searching a lot for it, but i dont find any solution. Can anyone help me?
My Custom Table View class
The error is shown in the blow screenshot (only is showing a part of last product because im draging to up to show the hidden product under the tabbar):
Thanks.
I've got the same problem and solved it using storyboard.
At Tab Bar Controller, go to attribute inspector, Simulated Metrics, and set the Bottom Bar to Opaque Tab Bar. That's it!
See image bellow for description.
Saudações! (Greetings!)
I found the answer to your question on another post, answered by dariaa, here:
Tab Bar covers TableView cells in iOS7
It worked great for me.
Please no credit for me, because I'm not the original guy who solved it.
In your custom TableViewController, add these two lines under [super viewDidLoad]:
- (void)viewDidLoad
{
[super viewDidLoad];
self.edgesForExtendedLayout = UIRectEdgeAll;
self.tableView.contentInset = UIEdgeInsetsMake(0., 0., CGRectGetHeight(self.tabBarController.tabBar.frame), 0);
}
My friends, I cannot tell you how badly I struggled from this. Not a single re-configuration of Story Board never helped me. The issue was exactly like in Original Post, I've managed to fix it using:
for swift 3
self.edgesForExtendedLayout = []
for objective-c
self.edgesForExtendedLayout = NO;
2 lines in viewDidLoad and that's it !
self.edgesForExtendedLayout = UIRectEdgeAll;
self.tableview.contentInset = UIEdgeInsetsMake(0.0f, 0.0f, CGRectGetHeight(self.tabBarController.tabBar.frame), 0.0f);
In iOS 7 viewController uses full height. There is a property introduced as
self.automaticallyAdjustsScrollViewInsets = NO;
set it to no. then check, or set UIEdgeInset if is not set right after it.
UIEdgeInsetsMake(top, left, bottom, right)
See here
https://developer.apple.com/library/ios/documentation/userexperience/conceptual/TransitionGuide/AppearanceCustomization.html
Edit: try also this
self.edgesForExtendedLayout = UIRectEdgeNone;
The root cause of this problem is that automaticallyAdjustsScrollViewInsets is effective only on the First scroll view in your VC's view Hierarchy. It is not documented by Apple, but it is the only way the VC will detect the scroll view needing to be modified unless you're using a UITableViewController.
So in order to fix your issue without manually adjusting the insets, do this:
Make sure "Adjust Scroll View Insets" is checked.
Make sure that the tableView is the first subview in the view Hierarchy.
(Move it upwards above all other elements)
UIViewController has two new properties to assist you : topLayoutGuide and bottomLayoutGuide. They return the height of the parent view controller's controls you need to avoid. In this case, bottomLayoutGuide will return the offset of the tab bar.
Your custom view controller is probably overriding a method and not invoking super's implementation where this would be done for you. I am guessing you are installing AutoLayout constraints or setting a view's frame manually to fill the view. You just need to include the value from [bottomLayoutGuide length] to your layout calculation. If you support rotation, you should update that value in willAnimateRotationToInterfaceOrientation:duration:.
UINavigationController and UITabBarController both have a transparency flag that can be set programmatically or in the storyboard.
The UINavigationController also has two flags that control if the content extends under the top or bottom bar. Again you can set them programmatically or in the storyboard. This will apply to all subviews.
Each UIViewController can set its own preference in code. The property is called edgesForExtendedLayout and you can set up all combinations.
Using those properties will allow AutoLayout and Springs'n'Struts to adjust the views the way you want them regardless of the device.
There are a lot more new properties in UIViewController that you will want to have a look at.
Try the following:
if ([self respondsToSelector:#selector(edgesForExtendedLayout)])
self.edgesForExtendedLayout = UIRectEdgeBottom;
I've got the same problem. One solution to it is to make the ToolBar not Translucent. Here's how to do it:
First select the tool bar from the document viewer
like here
Then uncheck Translucent like here
Hope this helps.
Thanks.
The problem was masked using:
-(void)viewDidLayoutSubviews
{
[super viewDidLayoutSubviews];
self.tableView.contentInset = UIEdgeInsetsMake(0, 0, 112, 0);
}
But it doesn't solve, because on each iPhone and on each app tableview i have a different space on bottom.
So this is a poor solution.
I dont know a way to solve it.
I solved my problem now, changing my BaseTableViewController to inherit from UIViewController to UITableViewController.
But using a TableView inside a UIViewController is not solved :(
Thanks.
maybe is not a right answer, also for that reason I post this answer so you can tell me if this answer could be a possible solution.
In my case, I like the translucent effect, so I have added a footer in the table and I have modified the scrollIndicators.
- (void)viewDidLoad
{
// Do any additional setup after loading the view.
[super viewDidLoad];
UIView *footer = [[UIView alloc]initWithFrame:CGRectMake(0, 0, self.agendaItemsTable.frame.size.width, self.tabBarController.tabBar.frame.size.height)];
self.agendaItemsTable.tableFooterView = footer;
self.agendaItemsTable.scrollIndicatorInsets = UIEdgeInsetsMake(0, 0, self.tabBarController.tabBar.frame.size.height, 0);
}
What do you think?
I had the same problem, and the up-voted answers did not solve it. See my answer to a similar question, Tab Bar covers TableView cells in iOS7.
I solved the issue by manually setting the table view's frame in the table view controller's viewWillAppear: method to the height of the screen - (status bar height + nav bar height + tab bar height).
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
// Adjust height of tableview (does not resize correctly in iOS 7)
CGRect tableViewFrame = self.tableView.frame;
tableViewFrame.size.height = [self heightForTableView];
self.tableView.frame = tableViewFrame;
}
- (CGFloat)heightForTableView
{
return CGRectGetHeight([[UIScreen mainScreen] bounds]) -
(CGRectGetHeight([[UIApplication sharedApplication] statusBarFrame]) +
CGRectGetHeight(self.navigationController.navigationBar.frame) +
CGRectGetHeight(self.tabBarController.tabBar.frame));
}
If anyone finds a better solution to this problem, please share!
For those like xarly who want the translucent effect, and for an Autolayout solution (without setting frames), see my answer here https://stackoverflow.com/a/26419986/1158074
I had a similar problem with collection view. Changing the collection view frame and content inset below fixed it for me...
guard let cv = collectionView,
let tabBar = tabBarController?.tabBar else { return }
// Resize collection view for tab bar
let adjustedFrame = CGRect(origin: cv.frame.origin,
size: CGSize(width: cv.frame.width, height: cv.frame.height - tabBar.frame.height))
cv.frame = adjustedFrame
// Adjust content inset for tab bar
let adjustedContentInsets = UIEdgeInsetsMake(0, 0, tabBar.frame.height, 0)
cv.contentInset = adjustedContentInsets
cv.scrollIndicatorInsets = adjustedContentInsets
Good luck!
I have a problem, I created a zoomable UIImageView with a UIScrollview, everything works perfect, exept the UIImageView is not in the center anymore and every time I hide the Tool- and NavigationBar the UIImageView/UIScrollView is moving up.
I already set the autoresizingMask:
scrollView.autoresizingMask = UIViewAutoresizingFlexibleTopMargin;
scrollView.autoresizingMask = UIViewAutoresizingFlexibleBottomMargin;
but it won't work, can someone please help me?
I had the same problem with iOS 7, and read I had to set
self.automaticallyAdjustsScrollViewInsets = NO;
for the view controller, but it did not work for me. After I have released I had to put it in viewDidLoad method of the parent view controller of the view controller.
Just like #Mert answered, you can either set it in code self.automaticallyAdjustsScrollViewInsets = NO; or you can set this in storyboard, in the scroll view in one of the inspectors you can un-check the checkbox that automatically adjusts the scroll view content.
EDIT
The checkbox is in the attributes inspector of the UIScrollView, it's called Autoresize Subviews under drawing section.
Btw, this behaviour only happens in iOs7, because of the transparent UINavigationBar thing.
