lfb-cd / UIViewController-Swizzled

Used to print the structure of your application as you use it

UIViewController+Swizzled

---

Category used to map your way inside an application. This is specially useful when you are working with a complex path and you are new to the project. Using this category will see the name of the UIViewController you are in, plus a representation of how deep you are.

This is a companion of the my other category NSURLConnection+Swizzled.h

Don't forget to disable it in production code. This is only for debugging

---

Requirements

Include the library:

• libobjc.dylib

And import the category where you want to use it:

• #import "UIViewController+Swizzled.h"

---

Adding UIViewController+Swizzled to your project

• Just add the two files inside your project (UIViewController+Swizzled.h and UIViewController+Swizzled.m).

Or

• CocoaPods: pod 'UIViewController+Swizzled', '~> 1.2'

---

Usage

In order to get the full output you should SWIZZ_IT right in the AppDelegate - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions. If for some reason you want to stop, just UN_SWIZZ_IT.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    SWIZZ_IT;
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    [self.window makeKeyAndVisible];
    
    // Your code...
    
    return YES;
}

This will output:
