Does not scroll when clicking on textfield that will be behind keyboard

[CyberMew]

This is how it looks like at the start:

If I click on the 1st textfield and press tab/arrow next then it works:

If I click on the 3rd textfield, it doesn't care for some reason:

Any idea why? The only thing I did was I made the UIView a UIScrollView instead, so that the whole UINavigationController doesn't scroll up. So this is the format:
Topmost UIView -> UIView -> UIScrollView -> UITextFields

I have not tested it on Simulator iOS 10 or on an actual device yet, though I expect them to behave the same.

I am having similar problem.
My text field inside the uicollectionview and class is presented modally with form sheet presentation.

Whenever I am pressing last text field of view, this text field shows behind the key board and not able to scroll to see that text field.

If I press next or previous button scroll till last text field is working fine.

I am using pod 'IQKeyboardManagerSwift', ‘4.0.0’

@CyberMew Make sure your scrollView does have correct autolayout constraint to calculate it's contentSize

[CyberMew]

The whole layout has autolayout applied and there wasn't any errors in the storyboard. I will double check again when I have time! Maybe @viral105 can verify in the meantime too

[hackiftekhar]

Please check in viewDidAppear that what contentOffset property of your ScrollView does have.

[viral105]

@hackiftekhar I have double checked my view and its constraints. Its ok. No issue with that.
Also I didn't written viewDidAppear in my VC and in all class i didn't set contentOffSet property.

[hackiftekhar]

ohh, very sorry @viral105 I mean contentSize, my bad.

[viral105]

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { if segue.identifier == "MyVC" { let obj: MyVC = segue.destinationViewController as! MyVC obj.preferredContentSize = CGSizeMake(900, 650) } }

This is what i have written in view controller from where I am presenting MyVC.
Is there anything wrong in above code ?

[viral105]

Also one more thing I have notice that, problem occurs only if presenting vc. When you push vc in that case it is working properly for me.

[hackiftekhar]

@viral105 I'm asking to set contentSize of UIScrollView, not preferredContentSize.

[viral105]

@hackiftekhar My All textfields inside the uicollectionview. Not in uiscrollview.

[hackiftekhar]

@viral105 Do you have any special configuration? Have you checked collection view demo on the demo project?

[viral105]

@hackiftekhar As a special configuration i can say that my presentation style is "Form Sheet" if it is "Default" then no issues. Yes, I checked collection view demo.

[hackiftekhar]

@viral105 Can you provide the demo project since I'm unable to reproduce the issue?

[viral105]

@hackiftekhar I fond the problem.
override func viewDidLayoutSubviews(){ self.mycollectionviewobj.collectionViewLayout.invalidateLayout() }
This lines of code are causing the problem.
Commenting this line "IQKeyboardManagerSwift" working fine for me in form sheet presentation style.
Thanks for your help.
