The Xcode error called ‘Frame for “Text View” will be different at run time.’ is frequent when you are trying to utilise Auto Layout by using reset to suggested constraints in Xcode Storyboard.

So here is how to fix it:

Step 01:
Above Debug: In your Xcode Storyboard view screen, you will have four buttons at the extreme right. Use the pin button, third from right, to add new constraints per item at the top, right, bottom, and left, and uncheck the constraint to margins.

There are instances when you want to transition or navigate from one UI screen to another by pressing a button.

Yes, you can link the button visually by control-clicking on it and then linking it to the required UI Screen on the storyboard.

But I will show you how you can do it programmatically with code defined & working differently for iPad & iPhone Storyboards.

I have used iOS Conditional coding syntax to differentiate iPhone & iPad Storyboards

Note: You can read about iOS Conditional Coding Here, How to detect user is using iPad or iPhone for iOS App at run time conditional coding purposes

You want to hide this ‘Back’ button when you transition from one screen to the next, probably the detail view screen, where Xcode automatically puts this for you without asking if you want it.

You can copy the below code to your ‘viewDidLoad’ method in your respective file:

Objective-C Code:

[self.navigationItem setHidesBackButton:YES animated: YES];

Swift Code:

self.navigationItem.setHidesBackButton(true, animated: true);

Hope it helps,

It always occurs when you are using the table view controller in your iOS Xcode project & when you navigate from the table view cell to the detail view of your app in the storyboard on the iOS Simulator or the actual device, the ‘Back,’ button Appears at the top left. What if you want to add a button beside the ‘Back’ button, And you want to know how? Here is the solution,

You have to add the following code in your ‘viewdidLoad’ function in your desired ViewController.m file:

self.navigationItem.leftItemsSupplementBackButton = YES;

You may wonder how to programmatically change the global Tint Colour of your iOS App in the Xcode project. i.e. Changing all UIBarButtonItems tint colours at once

Without selecting every single button & changing the tint for every single one & for the buttons added after that.

Here is the solution. As simple as a single line of code will remove the hassle from your mind & you can even re-change the global tint colour again by changing a few letters

Solution:
In your iOS App’s Xcode projects AppDelegate.m under function ‘didFinishLaunchingWithOptions’ add the below line

I assume you have gone through an earlier article related to this topic called:

How to add four or more navigation bar buttons in your iOS App XCode Project

Background:
Now you will be wondering how you can add a fourth button to the navigation bar of your iOS app with a custom image through code

Here is the solution:

I assume that you have added a navigation controller through Editor > Embed In > Navigation Controller in the xib (or formally nib) file in your XCode Projects’ Storyboard

Problem:
For example, you have added an Action button for Tweet Sheet on the Left, a Menu button on the right, and a Title button in the middle. But these three items don’t allow you to add a button at the second left position. This additional functionality enriches your app’s usp (unique selling point) or usability.

Reason:
It turns out this is a limitation of Interface Builder. It will only let you configure a single left and correct bar button item in a navigation bar. Don’t worry; you can still configure your remaining items in code. For example,

Solution:
Add the following code in the ‘viewDidLoad’ function in your View Controller’s Header file, i.e .h file
