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:

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

Suppose you are from the iOS Design and development community. In that case, you may already be familiar with using Apple’s list, i.e. Property List file functionality, whereby you store your data in an XML file type (Apple’s list file format).

Adding 1,000 lines of code in the list file is painful, so what you do is copy and paste through the source tab.

But if you have done something wrong with the structure of the .plist file, you will get an error something like this

ERROR: ‘The data couldn’t be read because it isn’t in the correct format.’
