在iOS中,TabBarController中的TabBar属性是只读的。如何将自定义项与特定视图控制器关联?如何访问tabBar中的UITabBarItem?
喜欢这个
CustomView *custom = [[CustomView alloc] init];
UITabBarItem *customTab = [[UITabBarItem alloc] initWithTitle:@"Custom" image:[UIImage imageNamed:@"custom.png"] tag:0];
SecondView *second = [[SecondView alloc] init];
UITabBarItem *secondTab = [[UITabBarItem alloc] initWithTitle:@"Next" image:[UIImage imageNamed:@"next.png"] tag:1];
NSArray *views = [NSArray arrayWithObjects:custom,second,nil];
[tabBarController setViewControllers:views];
//how do I set the individual TabBarItems (customTab,secondTab) to be associated
//with the views in question? tabBarController.tabBar is read only
答案 0 :(得分:5)
在每个视图控制器中,您可以设置tabBarItem属性。如果视图控制器归UITabBarViewController所有,则标签栏上的相关项目将相应更新。
像这样的东西
-(void)viewDidLoad {
[super viewDidLoad];
UITabBarItem *tbi = [[UITabBarItem alloc] initWithTitle:yourTitle image:yourIcon tag:yourTag];
[self setTabBarItem:tbi]
[tbi release];
}
显然,您不限制在viewDidLoad方法中执行此操作。
