How to Init a UIImage with a UIImage resulted from a call of a custom method?

Hi, I'm trying to define a custom method for resizing the images in my app. The custom method is defined in its own class, subclass of NSObject so that to use it for any image I have to manipulate in my (e.g.) UIViewControllers around the app. The parameters of the method are intended to be 1 UIImage (image to be resized) and 2 floats (width, height of the original image). The issue I have is that I am not sure how I can call the method during the Init of the UIImage that will contain the result of the method (i.e. resized image).

What I have tried:

  • call the custom method in the initialization of the UIImage, however I receive a syntax error.
  • rename the method into initWithData and change the result type of the method into a Data type. However, in this way it seems I won't be able to pass the width and height (or any additional parameter) of the resulting pictures.

Any help is greatly appreciated!
