It is so lucky to find the michaeltyson/TPKeyboardAvoiding to solve the Keyboard blocking text field problem. The TPKeyboardAvoiding is very nice. User just needs defining custom class as TPKeyboardAvoiding to make it happen.
My Question and Problem is:
In my condition, I have two views include scroll view. In each scroll view, there are sevral text fields. One view segue to other view. After segued view's last text field been edited, the previous view can't scroll to the last text filed.
All in all, after user editing one scroll view, the other view's content insets -> bottom value changed! Anyone has similar experience with me?
Correct one
Wrong one
My unsuccessful try: I have tried copy another paire of TPKeyboardAvoidingScrollView.h & .m file into project, and renamed them.It doesn't work.
BTW, even the segued view can't raise last textfield up entirely.
I have not used TPKeyboardAvoid with two Scroll views but sometime using alternate framework might solve your problem :
You can give try to following frameworks -

Seems like a pretty basic issue, but I have a tableViewController and at the top of the screen I've got a collection, beneath this I want to include a Search Bar. But for some reason it won't let me place this above the Table View Cell. It will let me add it into the collection view bizarrely but it goes behind the cells.
Is this a limitation caused by the fact I've included a Collection at the top of the screen? Is there only space for one element above a table on a tableViewController? Is there a workaround whilst still using a tableViewController?
Likely a noob question, but I'm still v noob
Is there only space for one element above a table on a
tableViewController?
Correct.
You get one header view area, and one footer view area for the tableViewController as a whole. (plus extras for the sections)
If you want a quick solution for a simple table then the tableViewController saves you about 60 seconds. - but if you want to do something more complex now or later, then you may want to consider using a regular UIViewController, dropping a UITableView into it and applying constraints as needed.
You would also need to remember to set the tableView dataSource and delegate up and comply to their protocols - or you go the diffableDataSource route.
Thanks #agentoverflow I couldn't find any documentation that explained the limitations of a UITableViewController.
Came up with my own solution. Put a view into the header area and put my collectionView and searchBar into that. Hooked the code up for both elements and both are working as expected.
I have a view controller with 8 text fields placed vertically in the view. The problem is that the keyboard obstructs some of the text fields so that the user cannot enter any data. So, basically I need a way to scroll the view.
I did try following the approach listed in this StackOverflow question but had trouble converting some of the objective-c to Swift.
How to make the view controller scroll to text field when keyboard appears
I was wondering if anyone has solved this problem in Swift and if so could post an example?
Thanks in advance!
Hi I've resolved this problem through subclassing UIScrollView. This is a swift version of scrollView and it works with auto layout.
You can checkout here https://github.com/honghaoz/AutoKeyboardScrollView
Basically, the idea is registering keyboard notifications (e.g. UIKeyboardWillChangeFrameNotification), and scroll to let active textFields visible when keyboarding is showing.
I have created a UITableView that is of type UITableViewStyleGrouped. I have then created several different sections with a few rows in each. Within each of these rows I have created a custom UITableViewCell that contains a UITextField. I also have one UITableViewCell that contains a UITextView.
I have also implemented a UIToolbar that appears on top of the UIKeyboard that allows the user to move through the UITextField's by pressing previous or next.
The issue I'm having is two-fold:
I need the UITableView to scroll so that when the next UITextField (or UITextView) becomes the first responder it is visible (even with the keyboard being displayed).
When a UITextField (or UITextView) is selected (without using the previous and next buttons) is should adjust so that the field is visible above the keyboard.
I have looked around at lots of different tutorials however none of them have resolved my issue. Any help you could offer would be hugely appreciated.
ADDITIONAL INFO:
I'm 100% certain that my app used to do all of the above automatically, however I seems to have stopped doing it now and I don't understand why. Is there a reason why this may of happened? Is there some function or something that I may have changed that would destroy this behaviour?
Probably no use to original poster now, but those having an issue like this where it once did work and then stopped...
check you don't have a:
- (void)viewWillAppear:(BOOL)animated
in your UITableViewController subclass!!!
using viewWillAppear in a UITableViewController breaks the "automagic tableView scrolling up when keyboard appears" behaviour.
I only found this by comparing laboriously an old version of a project where it did work with my latest source where it had stopped working.
Check out TaggedLocations sample code from apple. It does the same thing without any extra manipulation.
The key is that your viewcontrollers are following the standard. i.e you are NOT having container viewcontrollers such as UINavigationController within UIViewController.
You have to update tableview Frame yourself programatically...
and i am 100% sure that if you are 100% certain that your app used to do all of the above automatically ...than it is not your app.
Check the docs..here is the link
https://developer.apple.com/library/ios/#documentation/StringsTextFonts/Conceptual/TextAndWebiPhoneOS/ManageTextFieldTextViews/ManageTextFieldTextViews.html#//apple_ref/doc/uid/TP40009542-CH10-SW1
You will have to register for keyboard notifications..and then update your tableview frame.
And for next and previous.. you have to programmatically check which textfield became active..and then set the frame accordingly.
I know I can use codes to add UITableView one by one.
[self.view addSubview:tableview1];//
[self.view addSubview:tableview2];//
I hope to do the same thing in InterfaceBuilder, when I drag one UITableView onto another one, the new one always pushes the old one to the bottom, rather than just stays over the old one of UITableView.
Welcome any comment
Thanks
If you have a parent view that will contain your tableviews then you shouldn't have any problem. If you're trying to place them directly in a window then I could see a problem. If things aren't lining up the way you want you can always change their position via the Size Inspector or by nudging them with the arrow keys (shift-arrow key moves in 10 pixel increments).
Why anyone would want a tableview on top of another tableview escapes me.
Your parent view should be a subclass of uiviewcontroller and your xib should have the root view as a uiview and not uitableview.
I used two overlapping table views to show two different contents on the same view, which could be toggles using a segment switch. Apparently my client requirements were vague enough that I couldn't just filter out data like how the phone app displays all calls/missed calls list.
I am working on fitting a UITextView inside a UITableView. My table is grouped style with only one section and one row. I've looked through various previous questions but I am unable to get this idea working. I want the result to be the same as the "notes" section in the Calendar app on iPad. And Apple has done the same thing in the contacts app as well for notes. Do I need to use view animations to make the tableView row keep growing dynamically as and when more and more text is typed into the textView? What is the correct overall approach to make this idea work? Any pointers would be greatly appreciated. I get the points on how to resize the textview depending on text size and how to modify the height of the table row. But how do I make these work together to give it a dynamic animated feel like in the Apple apps?
Also another thing I noticed is that the cursor always lands at the beginning of the text view due to which the text gets overwritten and ugly on appending. Is there any method to get the cursor to go to next to the last character in the textview when I tap on it again while some text already exists inside it?
Thanks
You can refer to this Post for dynamically growing your uitableviewcell.
This library can help you grow UITextView with auto layout
https://github.com/MatejBalantic/MBAutoGrowingTextView
You can set-up the hooks (either in the library or you set-up the UITextView delegate) to make sure size of the table view cell get's recalculated based on the new UITextView size each time content of the text view is changed.
