方法一：
iOS 侧滑返回功能，自定义手势触发系统的pop动画。handleNavigationTransition:为系统私有API,系统自带的侧滑手势触发的回调，并且可以从页面任意地方滑动。
#import "ViewController.h"
@interface ViewController ()<UIGestureRecognizerDelegate>
@end
@implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
id target = self.navigationController.interactivePopGestureRecognizer.delegate;
UIPanGestureRecognizer *panGesture = [[UIPanGestureRecognizer alloc] initWithTarget:target action:@selector(handleNavigationTransition:)];
panGesture.delegate = self; // 设置手势代理，拦截手势触发
[self.view addGestureRecognizer:panGesture];
// 禁止系统自带的滑动手势
self.navigationController.interactivePopGestureRecognizer.enabled = NO;
}
- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer
{
// 当前控制器是根控制器时不触发手势
if(self.navigationController.childViewControllers.count == 1)
{
return NO;
}
return YES;
}
@end
方法二：
使用系统自带的侧滑：从边缘滑动。
self.navigationController.interactivePopGestureRecognizer.enabled = YES;
self.navigationController.interactivePopGestureRecognizer.delegate = (id)self;
就酱...
