简介:通过不同实际场景的描述,供大家参考完成 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,本文旨在通过不同实际场景的描述,供大家参考完成 Native 页面的定制化开发。
欢迎关注 mPaaS 公众号,下期推文,我们将为大家介绍 jsapi 下如何动态修改导航栏,敬请期待🤞
Native 修改导航栏左侧返回按钮
(一)自定义 NBPluginBase 插件中修改
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:@"取消" forState:UIControlStateNormal];
button.titleLabel.font = [UIFont systemFontOfSize:14.0];
[button setTitleColor:[UIColor blueColor] forState:UIControlStateNormal]; event.context.currentViewController.navigationItem.leftBarButtonItem.customView = button;
注:此方案自定义button,需要自行实现关闭页面逻辑。
2.修改返回按钮
监听 kNBEvent_Scene_NavigationItem_Left_Back_Create_After,在此监听事件中修改默认返回按钮样式,包括文案颜色、返回箭头等,文案内容默认不可修改。
//监听kNBEvent_Scene_NavigationItem_Left_Back_Create_After,在此监听事件中:
// 修改返回按钮样式
NSArray *leftBarButtonItems = event.context.currentViewController.navigationItem.leftBarButtonItems;
if ([leftBarButtonItems count] == 1) {
if (leftBarButtonItems[0] && [leftBarButtonItems[0] isKindOfClass:[AUBarButtonItem class]]) {
//在默认返回按钮基础上,修改返回箭头和文案颜色
AUBarButtonItem *backItem = leftBarButtonItems[0];
backItem.backButtonColor = [UIColor greenColor];
backItem.titleColor = [UIColor orangeColor];// [UIColor colorFromHexString:@"#00ff00"];
//隐藏、显示返回箭头
backItem.hideBackButtonImage = NO;
//backItem.backButtonTitle; 标题内容更改无效。
// 隐藏返回文案:文案设置为透明,保留返回按钮 s 点击区域
//backItem.titleColor = [UIColor clearColor];
}
}
(二)H5容器中自定义修改
1.方式一,在 viewWillAppear 获取自定义启动参数,根据参数自定义返回按钮。
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
// 当前页面的启动参数
NSDictionary *expandParams = self.psdScene.createParam.expandParams;
NSLog(@"[mpaas] expandParams: %@", expandParams);
}
获取启动参数后,依据自定义参数实现自定义按钮。
// 修改默认返回按钮文案颜色
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;// 返回按钮文本颜色
backItem.backButtonColor = [UIColor blueColor];// 设置箭头颜色
backItem.hideBackButtonImage = NO;//隐藏返回按钮图片,提供给框架使用
// 返回按钮图片 backItem.backButtonImage; 设置无效,只可隐藏or显示
}
}
}
2.方式二,可以在 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];
如果要修改 BarButtonItem 的文字大小、颜色等深度定制可以参考以下代码:
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];
}
//关闭所有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 修改导航栏左侧关闭按钮
(一)在自定义 NBPluginBase 插件中关闭按钮需自行创建
监听 kNBEvent_Scene_NavigationItem_Left_Close_Create_Before,在此监听事件中创建关闭按钮。
//监听kNBEvent_Scene_NavigationItem_Left_Close_Create_Before,在此监听事件中:
// 创建关闭按钮
[event preventDefault];
NBNavigationItemLeftCloseEvent *itemEvent = (NBNavigationItemLeftCloseEvent *)event;
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(0, 0, 44, 44);
button.backgroundColor = [UIColor whiteColor];
[button setTitle:@"关闭" forState:UIControlStateNormal];
[button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
itemEvent.customView = button;
监听kNBEvent_Scene_NavigationItem_Left_Close_Create_After,在此监听事件中修改关闭按钮样式。
//监听kNBEvent_Scene_NavigationItem_Left_Close_Create_After,在此监听事件中:
// 修改关闭按钮样式
[event preventDefault];
NBNavigationItemLeftCloseEvent *itemEvent = (NBNavigationItemLeftCloseEvent *)event;
UIButton *closeButton = (UIButton *)itemEvent.customView;
[closeButton setTitle:@"关闭" forState:UIControlStateNormal];
[closeButton setTitleColor:[UIColor greenColor] forState:UIControlStateNormal];
Native 修改导航栏标题
(一)在viewWillAppear 获取自定义启动参数,根据参数自定义标题
//打开H5离线包
NSString *appId = @"20190927";
[[MPNebulaAdapterInterface shareInstance]startH5ViewControllerWithNebulaApp:@{@"appId":appId,@"defaultTitle":@"测试",@"readTitle":@"NO",@"titleColor":@"ff0000",@"titleFont":@"18.0"}];//启动参数设置标题文案、颜色、大小;
这里的参数key值appId、defaultTitle、readTitle为框架默认不可修改,其余参数 key 值自定义。
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
// 当前页面的启动参数
NSDictionary *expandParams = self.psdScene.createParam.expandParams;
NSLog(@"[mpaas] expandParams: %@", expandParams);
// 设置导航栏标题
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 修改导航栏右侧按钮
(一)NBPluginBase 插件中自定义修改
1.在 NBPluginBase 中,
监听 kNBEvent_Scene_NavigationItem_Right_Setting_Create_Before,在此监听事件中创建导航栏右侧按钮。
//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,在此监听事件中修改导航栏右侧按钮。
//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,必须要在打开H5容器的启动参数中设置@{@”showOptionMenu”: @”YES”} 否则设置右侧按钮无效。
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办法去掉。
(二)H5 容器中自定义修改
1.在 viewWillAppear 获取自定义启动参数,根据参数自定义设置 AUBarButtonItem按钮。
(1)图片样式:
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)文字样式:
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.如果要修改 BarButtonItem 的文字大小、颜色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)隐藏原生导航栏
自定义导航栏,要先隐藏原生导航栏。
//隐藏容器类navBar
self.options.showTitleBar = NO;
//隐藏系统层navBar
[self.navigationController setNavigationBarHidden:YES];
(二)创建 navBarView
- 创建 AUCustomNavigationBar 初始化方法必须要 navigationBarForCurrentVC: 否则按钮设置无效。
- 赋值给 self.customNavigationBar 容器会自动适配H5页面高度,否则需自行适配页面。
//创建navBarView,必须要用此方法
AUCustomNavigationBar *navBar = [AUCustomNavigationBar navigationBarForCurrentVC:self];
[self.view addSubview:navBar];
//设置给容器VC
self.customNavigationBar = navBar;
(三)自定义背景样式
设置背景色、渐变色等,setNavigationBarBlurEffective 设置毛玻璃效果,支持更多样式自选。
//设置背景颜色,渐变色可自行设置
navBar.backgroundColor = [UIColor lightGrayColor];
[navBar setNavigationBarBlurEffectiveWithStyle:UIBlurEffectStyleDark]; // 毛玻璃效果,更多样式自选
(四)设置左侧导航按钮
1.设置左侧导航按钮方式一:
//导航左侧按钮
navBar.backButtonTitle = @"取消";
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,自行关联事件方式二,与方式一冲突,两者选其一。
//自行关联事件方式,与上述属性设置冲突。
//image和title两者选其一
[navBar setNavigationBarLeftItemWithImage:[UIImage imageNamed:@"back_button@2x"]target:self action:@selector(leftItemImageClick)];
[navBar setNavigationBarLeftItemWithTitle:@"取消" target:self action:@selector(leftItemTitleClick)];
(五)设置导航栏标题
1.设置导航栏标题方式一:
//设置导航栏标题
navBar.title = @"标题";
navBar.titleColor = [UIColor redColor];
navBar.titleLabel.font = [UIFont systemFontOfSize:14.0];
2.设置导航栏标题,AUDoubleTitleView双标题titleView方式二:
//设置双标题titleView
AUDoubleTitleView *titleView = [[AUDoubleTitleView alloc]initWithTitle:@"主标题" detailTitle:@"副标题"];
navBar.titleView = titleView;
//这里使用了mPaaS下双标题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)设置单个按钮方式一:
//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)设置单个按钮方式二:
//自行关联事件方式
//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];
