简介：通过不同理论场景的形容，供大家参考实现 Native 页面的定制化开发。
很多 mPaaS Coder 在接入 H5 容器后都会对容器的导航栏进行深度定制，本文旨在通过不同理论场景的形容，供大家参考实现 Native 页面的定制化开发。
欢送关注 mPaaS 公众号，下期推文，咱们将为大家介绍 jsapi 下如何动静批改导航栏，敬请期待
Native 批改导航栏左侧返回按钮
（一）自定义 NBPluginBase 插件中批改
1.自定义原生 BarButtonItem
监听 kNBEvent\_Scene\_NavigationItem\_Left\_Back\_Create\_Before，在此监听事件中设置自定义 BarButtonItem
//监听kNBEvent_Scene_NavigationItem_Left_Back_Create_Before，在此监听事件中：UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];button.frame = CGRectMake(0, 0, 44, 44);button.backgroundColor = [UIColor whiteColor];[button setTitle:@"勾销" forState:UIControlStateNormal];button.titleLabel.font = [UIFont systemFontOfSize:14.0];[button setTitleColor:[UIColor blueColor] forState:UIControlStateNormal]; event.context.currentViewController.navigationItem.leftBarButtonItem.customView = button;注：此计划自定义button，须要自行实现敞开页面逻辑。
2.批改返回按钮
监听 kNBEvent\_Scene\_NavigationItem\_Left\_Back\_Create\_After，在此监听事件中批改默认返回按钮款式，包含文案色彩、返回箭头等，文案内容默认不可批改。
//监听kNBEvent_Scene_NavigationItem_Left_Back_Create_After，在此监听事件中：// 批改返回按钮款式NSArray *leftBarButtonItems = event.context.currentViewController.navigationItem.leftBarButtonItems;if ([leftBarButtonItems count] == 1) { if (leftBarButtonItems[0] && [leftBarButtonItems[0] isKindOfClass:[AUBarButtonItem class]]) { //在默认返回按钮根底上，批改返回箭头和文案色彩 AUBarButtonItem *backItem = leftBarButtonItems[0]; backItem.backButtonColor = [UIColor greenColor]; backItem.titleColor = [UIColor orangeColor];// [UIColor colorFromHexString:@"#00ff00"]; //暗藏、显示返回箭头 backItem.hideBackButtonImage = NO; //backItem.backButtonTitle; 题目内容更改有效。 // 暗藏返回文案：文案设置为通明，保留返回按钮 s 点击区域 //backItem.titleColor = [UIColor clearColor]; }}（二）H5容器中自定义批改
1.形式一，在 viewWillAppear 获取自定义启动参数，依据参数自定义返回按钮。
- (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; // 以后页面的启动参数 NSDictionary *expandParams = self.psdScene.createParam.expandParams; NSLog(@"[mpaas] expandParams: %@", expandParams);}获取启动参数后，根据自定义参数实现自定义按钮。
// 批改默认返回按钮文案色彩 NSString *backButtonColorString = expandParams[@"backButtonColor"]; if ([backButtonColorString isKindOfClass:[NSString class]] && [backButtonColorString length] > 0) { UIColor *backButtonColor = [UIColor colorFromHexString:backButtonColorString]; NSArray *leftBarButtonItems = self.navigationItem.leftBarButtonItems; if ([leftBarButtonItems count] == 1) { if (leftBarButtonItems[0] && [leftBarButtonItems[0] isKindOfClass:[AUBarButtonItem class]]) { backItem.backButtonTitle = @"测试";// 返回按钮title backItem.titleColor = backButtonColor;// 返回按钮文本色彩 backItem.backButtonColor = [UIColor blueColor];// 设置箭头色彩 backItem.hideBackButtonImage = NO;//暗藏返回按钮图片，提供给框架应用 // 返回按钮图片 backItem.backButtonImage; 设置有效，只可暗藏or显示 } } }2.形式二，能够在 viewWillAppear 自定义整个返回区域 AUBarButtonItem 按钮、个数：
AUBarButtonItem *backItem = [AUBarButtonItem barButtonItemWithIconFontName:kICONFONT_BACK iconColor:[UIColor lightGrayColor] target:self action:@selector(custBack:)]; AUBarButtonItem *backItem = [AUBarButtonItem backBarButtonItemWithTitle:@"测试" backArrowColor:[UIColor redColor] target:self action:@selector(custBack:)];backItem.customView.frame = CGRectMake(0, 0, 44, 44); AUBarButtonItem *closeItem = [AUBarButtonItem barButtonItemWithIconFontName:kICONFONT_SYSTEM_CANCEL_BOLD iconColor:[UIColor lightGrayColor] target:self action:@selector(custClose:)];closeItem.customView.frame = CGRectMake(0, 0, 30, 44); self.navigationItem.leftBarButtonItems = @[backItem,closeItem];如果要批改 BarButtonItem 的文字大小、色彩等深度定制能够参考以下代码：
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];button.frame = CGRectMake(0, 0, 40, 40);[button setTitle:@"我的" forState:UIControlStateNormal];[button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];[button setBackgroundColor: [UIColor whiteColor]];button.titleLabel.font = [UIFont systemFontOfSize:14.0f];AUBarButtonItem *backItem = [[AUBarButtonItem alloc] initWithCustomView:button];//返回按钮事件- (void)custBack:(id)sender{ NSLog(@"back -----"); [self back];}//敞开所有session- (void)custClose:(id)sender{ NSLog(@"close ------"); NSArray<NBSession *> *sessions = [[NBContext sharedContext] sessions]; for (NBSession* session in sessions) { [[NBContext sharedContext] exitSession:session animated:YES]; }}Native 批改导航栏左侧敞开按钮
（一）在自定义 NBPluginBase 插件中敞开按钮需自行创立
监听 kNBEvent\_Scene\_NavigationItem\_Left\_Close\_Create\_Before，在此监听事件中创立敞开按钮。
//监听kNBEvent_Scene_NavigationItem_Left_Close_Create_Before，在此监听事件中：// 创立敞开按钮[event preventDefault];NBNavigationItemLeftCloseEvent *itemEvent = (NBNavigationItemLeftCloseEvent *)event;UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];button.frame = CGRectMake(0, 0, 44, 44);button.backgroundColor = [UIColor whiteColor];[button setTitle:@"敞开" forState:UIControlStateNormal];[button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];itemEvent.customView = button;监听kNBEvent\_Scene\_NavigationItem\_Left\_Close\_Create\_After，在此监听事件中批改敞开按钮款式。
//监听kNBEvent_Scene_NavigationItem_Left_Close_Create_After，在此监听事件中：// 批改敞开按钮款式[event preventDefault];NBNavigationItemLeftCloseEvent *itemEvent = (NBNavigationItemLeftCloseEvent *)event;UIButton *closeButton = (UIButton *)itemEvent.customView;[closeButton setTitle:@"敞开" forState:UIControlStateNormal];[closeButton setTitleColor:[UIColor greenColor] forState:UIControlStateNormal];Native 批改导航栏题目
（一）在viewWillAppear 获取自定义启动参数，依据参数自定义题目
//关上H5离线包NSString *appId = @"20190927"; [[MPNebulaAdapterInterface shareInstance]startH5ViewControllerWithNebulaApp:@{@"appId":appId,@"defaultTitle":@"测试",@"readTitle":@"NO",@"titleColor":@"ff0000",@"titleFont":@"18.0"}];//启动参数设置题目文案、色彩、大小;这里的参数key值appId、defaultTitle、readTitle为框架默认不可批改，其余参数 key 值自定义。
- (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; // 以后页面的启动参数 NSDictionary *expandParams = self.psdScene.createParam.expandParams; NSLog(@"[mpaas] expandParams: %@", expandParams); // 设置导航栏题目 NSString *titleColorString = expandParams[@"titleColor"]; NSString *titleFont = expandParams[@"titleFont"]; if ([titleColorString isKindOfClass:[NSString class]] && [titleColorString length] > 0 && [titleFont length] > 0) { UIColor *titleColor = [UIColor colorFromHexString:titleColorString]; id<NBNavigationTitleViewProtocol> titleView = self.navigationItem.titleView; [[titleView mainTitleLabel] setTextColor:titleColor]; float font = [titleFont floatValue]; [[titleView mainTitleLabel] setFont:[UIFont systemFontOfSize:font]]; }}Native 批改导航栏右侧按钮
（一）NBPluginBase 插件中自定义批改
1.在 NBPluginBase 中，
监听 kNBEvent\_Scene\_NavigationItem\_Right\_Setting\_Create\_Before，在此监听事件中创立导航栏右侧按钮。
//监听kNBEvent_Scene_NavigationItem_Right_Setting_Create_Before，在此监听事件中：NBNavigationItemRightSettingEvent *settingEvent = (id)event;settingEvent.adjustsWidthToFitText = YES;settingEvent.maxWidth = [UIScreen mainScreen].bounds.size.width / 4.0f;UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];button.frame = CGRectMake(0, 0, 33, 40);[button setTitle:@"设置" forState:UIControlStateNormal];[button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];[button setBackgroundColor: [UIColor whiteColor]];settingEvent.customView = button;[event preventDefault];2.在 NBPluginBase 中
监听kNBEvent\_Scene\_NavigationItem\_Right\_Setting\_Create\_After，在此监听事件中批改导航栏右侧按钮。
//监听kNBEvent_Scene_NavigationItem_Right_Setting_Create_After，在此监听事件中：NBNavigationItemRightSettingEvent *settingEvent = (id)event;settingEvent.adjustsWidthToFitText = YES;settingEvent.maxWidth = [UIScreen mainScreen].bounds.size.width / 4.0f;UIButton *button = settingEvent.customView;button.titleLabel.font = [UIFont systemFontOfSize:14.0f];button.frame = CGRectMake(0, 0, 40, 40);[button setTitleColor:[UIColor redColor] forState:UIControlStateNormal];[button setTitleColor:[UIColor blackColor] forState:UIControlStateHighlighted];[button setBackgroundColor: [UIColor whiteColor]];[event stopPropagation];//去掉默认按钮图片注：
1. 在插件中自定义导航栏右侧按钮，必须要在关上H5容器的启动参数中设置@{@"showOptionMenu": @"YES"} 否则设置右侧按钮有效。
2. 必须要在kNBEvent\_Scene\_NavigationItem\_Right\_Setting\_Create\_After监听事件中实现[event stopPropagation];否则showOptionMenu按钮的默认图片没有方法去掉。
（二）H5 容器中自定义批改
1.在 viewWillAppear 获取自定义启动参数，依据参数自定义设置 AUBarButtonItem按钮。
（1）图片款式：
AUBarButtonItem *rightItem1 = [[AUBarButtonItem alloc] initWithImage:image1 style:UIBarButtonItemStylePlain target:self action:@selector(rightBarItemPressed1)];AUBarButtonItem *rightItem2 = [[AUBarButtonItem alloc] initWithImage:image2 style:UIBarButtonItemStylePlain target:self action:@selector(rightBarItemPressed2)];//单个按钮self.navigationItem.rightBarButtonItem = rightItem1;//多个按钮self.navigationItem.rightBarButtonItems = @[rightItem1, rightItem2];（2）文字款式：
AUBarButtonItem *titleItem1 = [[AUBarButtonItem alloc]initWithTitle:@"按钮" style:UIBarButtonItemStylePlain target:self action:@selector(rightBarItemPressed1)];AUBarButtonItem *titleItem2 = [[AUBarButtonItem alloc]initWithTitle:@"右侧" style:UIBarButtonItemStylePlain target:self action:@selector(rightBarItemPressed2)];//单个按钮self.navigationItem.rightBarButtonItem = rightItem1;//多个按钮self.navigationItem.rightBarButtonItems = @[titleItem1, titleItem2];2.如果要批改 BarButtonItem 的文字大小、色彩等深度定制参考以下代码：
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];button.frame = CGRectMake(0, 0, 40, 40);[button setTitle:@"我的" forState:UIControlStateNormal];[button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];[button setBackgroundColor: [UIColor whiteColor]];button.titleLabel.font = [UIFont systemFontOfSize:14.0f];AUBarButtonItem *rightItem = [[AUBarButtonItem alloc] initWithCustomView:button];Native 自定义导航栏
（一）暗藏原生导航栏
自定义导航栏，要先暗藏原生导航栏。
//暗藏容器类navBarself.options.showTitleBar = NO;//暗藏零碎层navBar[self.navigationController setNavigationBarHidden:YES];（二）创立 navBarView
- 创立 AUCustomNavigationBar 初始化办法必须要 navigationBarForCurrentVC: 否则按钮设置有效。
- 赋值给 self.customNavigationBar 容器会主动适配H5页面高度，否则需自行适配页面。
//创立navBarView，必须要用此办法AUCustomNavigationBar *navBar = [AUCustomNavigationBar navigationBarForCurrentVC:self];[self.view addSubview:navBar];//设置给容器VCself.customNavigationBar = navBar;（三）自定义背景款式
设置背景色、渐变色等，setNavigationBarBlurEffective 设置毛玻璃成果，反对更多样式自选。
//设置背景色彩，渐变色可自行设置navBar.backgroundColor = [UIColor lightGrayColor];[navBar setNavigationBarBlurEffectiveWithStyle:UIBlurEffectStyleDark]; // 毛玻璃成果，更多样式自选（四）设置左侧导航按钮
1.设置左侧导航按钮形式一：
//导航左侧按钮navBar.backButtonTitle = @"勾销";navBar.backTitleLabel.font = [UIFont systemFontOfSize:16.0];navBar.backButtonTitleColor = [UIColor orangeColor];navBar.backButtonImage = [UIImage imageNamed:@"back_button@2x"];[navBar addSubview:navBar.leftItem];2.设置左侧导航按钮，自行关联事件形式二，与形式一抵触，两者选其一。
//自行关联事件形式，与上述属性设置抵触。//image和title两者选其一[navBar setNavigationBarLeftItemWithImage:[UIImage imageNamed:@"back_button@2x"]target:self action:@selector(leftItemImageClick)];[navBar setNavigationBarLeftItemWithTitle:@"勾销" target:self action:@selector(leftItemTitleClick)];（五）设置导航栏题目
1.设置导航栏题目形式一:
//设置导航栏题目navBar.title = @"题目";navBar.titleColor = [UIColor redColor];navBar.titleLabel.font = [UIFont systemFontOfSize:14.0];2.设置导航栏题目，AUDoubleTitleView双题目titleView形式二：
//设置双题目titleViewAUDoubleTitleView *titleView = [[AUDoubleTitleView alloc]initWithTitle:@"主题目" detailTitle:@"副标题"];navBar.titleView = titleView;//这里应用了mPaaS下双题目UI，也可自行实现titleView（六）设置导航栏右侧按钮
1.单个右侧按钮
（1）设置单个按钮形式一：
//设置导航右侧按钮navBar.rightItemTitle = @"菜单";navBar.rightItemTitleColor = [UIColor blackColor];//image和title两者选其一navBar.rightItemImage = [UIImage imageNamed:@"rightTT@2x"];（2）设置单个按钮形式二：
//自行关联事件形式//image和title两者选其一[navBar setNavigationBarRightItemWithTitle:@"菜单" target:self action:@selector(rightItemTitleClick)];[navBar setNavigationBarRightItemWithImage:[UIImage imageNamed:@"rightTT@2x"] target:self action:@selector(rightItemImageClick)];2.深度自定义单、多个右侧按钮
深度自定义右侧按钮、文字、大小、图片，自行关联事件。
//深度自定义右侧按钮、文字、大小、图片、关联事件AUButton *button = [AUButton buttonWithStyle:AUButtonStyleNone title:@"右一" target:self action:@selector(rightItemTitleClick)];button.titleLabel.font = [UIFont systemFontOfSize:16.0];[button setTitleColor:[UIColor redColor] forState:UIControlStateNormal]; AUButton *button1 = [AUButton buttonWithStyle:AUButtonStyleNone];[button1 setImage:[UIImage imageNamed:@"rightTT@2x"] forState:UIControlStateNormal];navBar.rightItemList = @[button,button1];本文作者：阿里云 mPaaS TAM 团队（石鹏飞 荣阳）
