升级60-beta之后，发现10.1.32中对navBar做的修改，比如返回按钮，右边按钮做的自定义修改失效了，经过和mPaaS沟通，总结修改方式如下：
自定义Plugin
- 自定义Plugin 继承NBPluginBase
@interface H5Plugin4NavigationBar: NBPluginBase
@end
- 监听事件
[self.target addEventListener:kNBEvent_Scene_NavigationItem_Left_Back_Create_After
withListener:self
useCapture:NO];
- 在对应事件中做处理
返回按钮
if ([kNBEvent_Scene_NavigationItem_Left_Back_Create_After isEqualToString:event.eventType]) {
//MARK: 更改已创建LeftBarItem的样式
UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
[btn setFrame:CGRectMake(0, 0, 44, 44)];
[btn setImage:[UIImage imageNamed:@"header-back"] forState:UIControlStateNormal];
[btn setTitle:@" " forState:UIControlStateNormal];
[btn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[btn addTarget:event.context.currentViewController action:@selector(back) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *backItem = [[UIBarButtonItem alloc] initWithCustomView:btn];
NSArray *leftBarButtonItems = event.context.currentViewController.navigationItem.leftBarButtonItems;
NSMutableArray *arr = [NSMutableArray arrayWithArray:leftBarButtonItems];
[arr enumerateObjectsWithOptions:NSEnumerationReverse usingBlock:^(UIBarButtonItem* _Nonnull item, NSUInteger idx, BOOL * _Nonnull stop) {
if ([item isKindOfClass:[AUBarButtonItem class]]) {
[arr removeObject:item];
[arr addObject:backItem];
*stop = YES;
}
}];
[event.context.currentViewController.navigationItem setLeftBarButtonItems:arr];
[event preventDefault];
}
关闭按钮，关闭按钮修改方式应该和返回一样，这边只是屏蔽关闭按钮
if ([kNBEvent_Scene_NavigationItem_Left_Close_Create_Before isEqualToString:event.eventType]) {
//MARK: 更改已创建LeftBarItem的样式
NBNavigationItemEvent *e = (id)event;
e.customView = nil;
[e preventDefault];
}
标题栏
以前是这样的
//10.1.32 中标题栏的修改方式是这样的，60-beta中改了
if ([kNBEvent_Scene_TitleView_Create_After isEqualToString:event.eventType]) {
//MARK: 更改已创建TitleView的样式
NBNavigationTitleViewEvent *e = (id)event;
[[e.titleView mainTitleLabel] setFont:[UIFont systemFontOfSize:18]];
[[e.titleView mainTitleLabel] setTextColor:[UIColor blackColor]];
}
60-beta中是下面这个样子
id <NBNavigationTitleViewProtocol> titleView = (NBNavigationTitleView *)self.navigationItem.titleView;
[[titleView mainTitleLabel] setFont:[UIFont systemFontOfSize:9]];
[[titleView mainTitleLabel] setTextColor:[UIColor redColor]];
右按钮
BOOL isNebulaApp = [expandParams[@"isNebulaApp"] isEqualToString:@"1"];
//这边的isNebulaApp用来控制入口是小程序还是普通h5APP，mPaaS未提供容器内判断是小程序还是H5包的方法，只能通过启动时传参来判断
UIBarButtonItem * rightItem = self.navigationItem.rightBarButtonItems.firstObject;
if (isNebulaApp && rightItem) {
UIButton * rightButton = (UIButton *)rightItem.customView;
[rightButton setBackgroundImage:[UIImage imageNamed:@"shouye-hei"] forState:(UIControlStateNormal)];
}
