You're more amazing! thank YOU

[@arijitganguly83]

thanks... this one helped a lot

[@tahevol]

Thank you. This helped me a lot with NC. The concept is simple, but I was hung up for a long time getting text out of a function on one VC and into a labels on other VCs. You made the components of the NC Post and Observer system clear.

Thanks!

Please upload one more video for this pass data.. Multiple labels and multiple textfields.. Data transfer and save it

[@iOSAcademy]

Sure!

[@GG-hk5iz]

How do you manage to explain any concept with such a simplicity?

[@rafatwasef8518]

Thanks A lot that is great I have a question how to switch to other story board from NSObject class I used what you wrote but it said no present in NSObject please help me

[@heliumstein1]

helpful but the zoom in feature you have when presenting is disorientating

[@asherazeem3282]

That a lot bro, it is a good way for moving data from A-> B or B->A Controller.

[@hiwottesfaye8710]

Thank you

Great Video!!! saved me, but how do you manage to do all zooms while recording? its so epic since i have bad sight, which software do you use?

[@Christian031780]

Your videos are great, but zooming so often might be little bit distracting and hard to follow. You might want to stick with one view and make the font size bigger and it will be fine. Thank you for your videos.

[@iOSAcademy]

Thanks for the feedback :) And thanks for watching!

[@maryannadelman4438]

Good tutorial! Question: using the completionHandler version, would it be possible to have the save button on vc2 make an image on vc1 switch to another image?

[@shoilett1]

What about using segues? Are segues considered outdated?

[@GG-hk5iz]

@iOS Academy , Really looking forward to see Swift UI stuff from your side

[@vspianist]

i tested this on my iPhone and the keyboard doesn't dismiss, how do i dismiss the keyboard

[@iOSAcademy]

ResignFirstResponder

[@PFSGMBH]

Thanks for the excellent tutorial. I have used the notification solution to send an object from the second to the first viewController. But what about sending an object from the first to the second. I was setting the observer and a different notification name and pushed the second viewController on the stack by navigationController?.pushViewController() . But the notification does not get noted . Any idea how to get the object to the second ViewController ?

[@lokeshchinatatareddy1069]

Can you say how to do in MVVM

[@leninvladimirpacas6211]

Thank you so much for the tutorial, it was excellent. I love it

[@supertonyxd]

Thank you for the tutorial. I got one question as I am not using storyboard but XIB to do. So for the line "let vc = storyboard?.instantiateViewController(identifier: "other") as! OtherViewController" should not work for me... What should I do with this? Thanks

[@dugrut1325]

when you messed up with the button, on the OtherViewController, at first I thought I'm really lost, how is then actually possible....?

[@AviationMaster]

Hello! Is it possible to copy and paste code from one cocoa touch class view controller.swift to another view controller.swift?

[@hulkxp3020]

how can I do this with a switch?

[@bearishlilly4703]

how does one capture a global variable data from one view controller to another without using segue or moving to a new viewcontroller?

[@ananyousef889]

really thank you so much for the valuable information , I am an iOS Development student , I am on my final project and I am trying to send data from a viewController (textfield and label) to a uiTabelView , can you please let me know what is the best way to do so ?

[@iOSAcademy]

You are most welcome - closure sounds like the approach you want

[@RyeGuyWpg74]

This doesn't seem to be working when I try to do it the other way. Push data from the first vc to the second. I am posting the notification but I have to do it before pushing the second view controller and the second vc never receives the notification.

[@PutraTrie]

how to show data from login user by json ?

[@balakrishnasalla]

notification center not working

[@iOSAcademy]

Check your observer

[@sharkcraft384]

Where is the github repo? Btw I love ur vids

[@iOSAcademy]

Thanks, I dont think I mmade one for this one

[@vspianist]

how do you store the text value in a double and pass that between view controlers

[@iOSAcademy]

You can just pass a string

[@SSQMinky]

Is there a way to do this on a macOS app, where a vc1 button can change text on vc1 and vc2? Basically like a text display for extended view, where vc1 controls what the text is, and it displays on vc1 and vc2. Once a button on vc1 is pressed, it changes the text on vc1 and vc2. How to make this work?

[@Tenkai165]

For me, I am still unable to see the completionHandler in my initial viewcontroller. The error says "Value type of 'ViewController' has no member 'completionHandler' " I have added public in front of the variable

[@theevanator9252]

One question I have is how to save information in your app so that when you renter the app it’s still there

[@iOSAcademy]

Hi there, to do this you can use User Defaults or a Database. I recently published two videos explaining each of these topics - cheers!

[@cem890]

Hi. I have 3 view controllers.First home, second login and third about news. They are connected with segues. And I use unwind segue for third viewController. Because when I hit back button it returns to login screen. When I use unwind segue it was working good but one problem is my login screen is still seen about 1 second. How can I solve that. Thank you.

[@Beebreloaded]

Am I the only one getting UIRESPONDER in my assistant editor even after I create a new class for my View Controller ??

[@TomGalland]

Followed and finished this tutorial today! Thank you! I'm struggling with the next step to Passing data. If I wanted to collect data from Two View Controllers, say "Other" & "More", and then bring it back into noteViewController. How would I do that? Example, 1. User clicks "OtherScreen" from note. 2. Types in to the "OtherViewController" and clicks a "Next Page" Button 3. Types in to the "MoreViewController" and clicks "Save"

[@iOSAcademy]

Thanks for watching. To do what you described you have several options. You can retain the data somewhere and use closures to pass the data back like completion Handlers. You can use the delegate / datasource pattern. Or you can use the notification center pattern.

how do I do a conditional statement? i have a code that does something like this: input(text field) < 5 { (sends me to view controller2) } if-else input(text field) > 5{ (sends me view controller1)

[@stefvanzwienen608]

Man, I really don't get it. I followed about 10 tutorials but I never get the option 'present'. I just don't know how to change the current viewcontroller programmatically.. I just don't know what i'm doing wrong. Could you help me?

[@iOSAcademy]

Hey, sometimes Xcode autocomplete just sucks. Try typing it in your self: self.present(, animated: true)

[@stefvanzwienen608]

iOS Academy That actually worked 😅 thank you!!!

please stop zooming in and out it is highly visible when you keep it in a normal angel

I had to stop watching because your constant zooming in and out was very jarring. Other than that it seemed like you were doing well explaining it.

Stop Zooming please.. It hurts our eyes
