There's no way to show it

My emulator runs normally. I change the code, but I cannot change it after saving. The log I get is as follows

💉 *** Compiling /Users/lishihang/Desktop/asd/asd/ViewController.m ***
💉 Loading .dylib - Ignore any duplicate class warning...
objc[4037]: Class ViewController is implemented in both /Users/lishihang/Library/Developer/CoreSimulator/Devices/E60C148D-0324-4667-A03B-9C8C13C9B0EE/data/Containers/Bundle/Application/36260E11-54A9-4BD1-ACE8-8018F23DE36B/asd.app/asd (0x1093e7ce8) and /Users/lishihang/Library/Containers/com.johnholdsworth.InjectionIII/Data/eval105.dylib (0x1271bd120). One of the two will be used. Which one is undefined.

hey @CreatSuns, If you look closer at the message you'll see that this should be ignored :)

Messages that have the prefix 💉 belong to InjectionIII whereas Class ViewController is implemented… belong to the system and is nothing that we can opt-out from showing.

I can implement it but I have to declare the injected method. Is there any way I can inject it into real time without having to declare it?

[zenangst]

@CreatSuns you mean you need to add @objc func injected() {} into your classes for it to work?
This is actually by design so that InjectionIII knows which classes should be "sweeped" when injection happens.

What you could do is to add the method using an extension and then decide what the injected method should do for the class. Take a view controller for example, then you could do something like this:

extension UIViewController {
  @objc func injected() {
    viewDidLoad()
    viewWillAppear(true)
    viewDidAppear(true)
  }
}

This should trigger the view lifecycle every time a view controller is saved.
Hope I understood this correctly and that it was helped :)

Thanks for your advice

add an @objc
injected() method or subscribe to the "INJECTION_BUNDLE_NOTIFICATION".
