How to rename the IBOutlet property without lose the connection

Question

I work with old project and in some part of the project, the naming convention is not good so I want to change it.
For example:

@property (weak, nonatomic) IBOutlet UIButton *btnRequestCode;
rename it to -> @property (weak, nonatomic) IBOutlet UIButton *requestCodeButton;

I know that I can delete the IBOutlet then reconnect but it may take many time and easy make error if careless

Any safe and fast way to do it?

I have tried Refactor -> Rename but it doesn't work and give me an warning

Any help or suggestion would be great appreciated.

Answer 2

Xcode 9, Refactor > Rename

New in Xcode 9 you can rename an outlet (or action) in the code and storyboard at the same time.

*DISCLAIMER: This feature only works in Xcode 9 (released September 2017) and above. Make sure to backup your project before using it. After making outlet name changes, test the affected screen(s) to make sure there are not issues. I tested this in a sample Objective C project successfully but it could cause problems in existing, more complex projects.

To rename an outlet...  

1. Navigate to outlet in the header file

@property (weak, nonatomic) IBOutlet UIButton *btnRequestCode;

 

2. Right click on outlet, select "Refactor > Rename...".

 

3. Change the outlet name

4. Select the "Rename" button or the Enter key

 

The outlet is renamed in the code and storyboard

@property (weak, nonatomic) IBOutlet UIButton *requestCodeButton;
