iOS滑动全屏实现返回功能

本文实例为大家分享了iOS滑动全屏实现返回功能的具体代码，供大家参考，具体内容如下

系统自带的滑动返回功能，只能滑动边缘返回，而我们希望通过滑动全屏实现返回功能。

定义BaseNavigationController来取代UINavigationController

//BaseNavigationController.h
#import

@interfaceBaseNavigationController:UINavigationController

@end

//BaseNavigationController.m
#import"BaseNavigationController.h"

@interfaceBaseNavigationController()

@end

@implementationBaseNavigationController

#pragmamark-系统方法
+(void)load
{
UINavigationBar*navBar=[UINavigationBarappearanceWhenContainedIn:self,nil];

//只要是通过模型设置，都是通过富文本设置
//设置导航条标题=>UINavigationBar
NSMutableDictionary*attrs=[NSMutableDictionarydictionary];
attrs[NSFontAttributeName]=[UIFontboldSystemFontOfSize:20.0];
[navBarsetTitleTextAttributes:attrs];

//设置导航条背景图片
[navBarsetBackgroundImage:[UIImageimageNamed:@"navigationbarBackgroundWhite"]forBarMetrics:UIBarMetricsDefault];
}

-(void)viewDidLoad{
[superviewDidLoad];
//Doanyadditionalsetupafterloadingtheview.

//自己控制返回手势
//self.interactivePopGestureRecognizer.delegate=self;
//NSLog(@"self.interactivePopGestureRecognizer:%@",self.interactivePopGestureRecognizer);
//NSLog(@"self.interactivePopGestureRecognizer.delegate:%@",self.interactivePopGestureRecognizer.delegate);

//全屏返回手势，而不是边缘返回手势
UIPanGestureRecognizer*pan=[[UIPanGestureRecognizeralloc]initWithTarget:self.interactivePopGestureRecognizer.delegateaction:@selector(handleNavigationTransition:)];
[self.viewaddGestureRecognizer:pan];
//控制手势什么时候触发，只有非根控制器才需要出发手势
pan.delegate=self;
//禁止之前手势
self.interactivePopGestureRecognizer.enabled=NO;
}

/**
*self.interactivePopGestureRecognizer:;target=<(action=handleNavigationTransition:,target=<_UINavigationInteractiveTransition0x7fb57dc1c570>)>>
*self.interactivePopGestureRecognizer.delegate:<_UINavigationInteractiveTransition:0x7fb57dc1c570>
*/

#pragmamark-UIGestureRecognizerDelegate
-(BOOL)gestureRecognizer:(UIGestureRecognizer*)gestureRecognizershouldReceiveTouch:(UITouch*)touch
{
//当不是根控制器时才会触发返回手势
return(self.childViewControllers.count>1);
}

#pragmamark-重写
-(void)pushViewController:(UIViewController*)viewControlleranimated:(BOOL)animated
{
if(self.childViewControllers.count>0){//代表不是根控制器

//自定义返回按钮覆盖了系统的返回手势
viewController.navigationItem.leftBarButtonItem=[UIBarButtonItemsetBackButtonItemWithImage:[UIImageimageNamed:@"navigationButtonReturn"]highlightedImage:[UIImageimageNamed:@"navigationButtonReturnClick"]target:selfaction:@selector(backClick)title:@"返回"];
}

[superpushViewController:viewControlleranimated:animated];
}

-(void)backClick
{
[selfpopViewControllerAnimated:YES];
}

@end

UIBarButtonItem+item

//UIBarButtonItem+item.h
#import

@interfaceUIBarButtonItem(item)

+(UIBarButtonItem*)setBarButtonItemWithImage:(UIImage*)imagehighlightedImage:(UIImage*)highlightedImagetarget:(id)targetaction:(SEL)action;

+(UIBarButtonItem*)setBarButtonItemWithImage:(UIImage*)imageselectedImage:(UIImage*)selectedImagetarget:(id)targetaction:(SEL)action;

+(UIBarButtonItem*)setBackButtonItemWithImage:(UIImage*)imagehighlightedImage:(UIImage*)highlightedImagetarget:(id)targetaction:(SEL)actiontitle:(NSString*)title;

@end


//UIBarButtonItem+item.m
#import"UIBarButtonItem+item.h"

@implementationUIBarButtonItem(item)

+(UIBarButtonItem*)setBarButtonItemWithImage:(UIImage*)imagehighlightedImage:(UIImage*)highlightedImagetarget:(id)targetaction:(SEL)action
{
//1.leftBarButtonItem
UIButton*leftButton=[UIButtonbuttonWithType:UIButtonTypeCustom];
[leftButtonsetImage:imageforState:UIControlStateNormal];
[leftButtonsetImage:highlightedImageforState:UIControlStateHighlighted];
[leftButtonsizeToFit];

//按钮点击事件
[leftButtonaddTarget:targetaction:actionforControlEvents:UIControlEventTouchUpInside];

//由于使用button会使得点击范围增大，所以将button放进view中，然后赋值
UIView*leftView=[[UIViewalloc]initWithFrame:leftButton.bounds];
[leftViewaddSubview:leftButton];
return[[UIBarButtonItemalloc]initWithCustomView:leftView];
}

+(UIBarButtonItem*)setBackButtonItemWithImage:(UIImage*)imagehighlightedImage:(UIImage*)highlightedImagetarget:(id)targetaction:(SEL)actiontitle:(NSString*)title
{
//设置返回按钮
UIButton*backButton=[UIButtonbuttonWithType:UIButtonTypeCustom];
[backButtonsetTitle:titleforState:UIControlStateNormal];
[backButtonsetImage:imageforState:UIControlStateNormal];
[backButtonsetImage:highlightedImageforState:UIControlStateHighlighted];
[backButtonsetTitleColor:[UIColorblackColor]forState:UIControlStateNormal];
[backButtonsetTitleColor:[UIColorredColor]forState:UIControlStateHighlighted];
[backButtonaddTarget:targetaction:actionforControlEvents:UIControlEventTouchUpInside];
backButton.contentEdgeInsets=UIEdgeInsetsMake(0,-15,0,0);
[backButtonsizeToFit];

return[[UIBarButtonItemalloc]initWithCustomView:backButton];
}

+(UIBarButtonItem*)setBarButtonItemWithImage:(UIImage*)imageselectedImage:(UIImage*)selectedImagetarget:(id)targetaction:(SEL)action
{
//1.leftBarButtonItem
UIButton*leftButton=[UIButtonbuttonWithType:UIButtonTypeCustom];
[leftButtonsetImage:imageforState:UIControlStateNormal];
[leftButtonsetImage:selectedImageforState:UIControlStateSelected];
[leftButtonsizeToFit];

//按钮点击事件
[leftButtonaddTarget:targetaction:actionforControlEvents:UIControlEventTouchUpInside];

//由于使用button会使得点击范围增大，所以将button放进view中，然后赋值
UIView*leftView=[[UIViewalloc]initWithFrame:leftButton.bounds];
[leftViewaddSubview:leftButton];
return[[UIBarButtonItemalloc]initWithCustomView:leftView];
}
