Enable iOS7 swipe-to-back when custom back button is set.

SwipeBack plays with iOS native gesture recognizers, so you can also use it to disable swipe-to-back feature.

Use CocoaPods.

platform :ios, '7.0'
pod 'SwipeBack', '~> 1.1'

Just install SwipeBack with CocoaPods. Your application now supports swipe-to-back feature.

You can set swipeBackEnabled for a specific UINavigationController. Default value is YES.

#import <SwipeBack/SwipeBack.h>

// ...

- (void)viewWillAppear:(BOOL)animated
{
    self.navigationController.swipeBackEnabled = NO;
}
