问题描述
我有两个 viewcontrollers.->AViewController，BViewController
AViewController 需要创建一个 BViewController 对象.然后 presentmodalcontroller :转到 BViewController .
AViewController need to create an object of BViewController.And presentmodalcontroller: to go to the BViewController.
并且 BViewController 也需要创建一个 AViewController 的对象，以便可以在 BViewController的方法内更新标签文本.
And BViewController
need to create an object of the AViewController
as well, so that is can update the label text inside BViewController
's method.
已尝试导入 BViewController 中的 AViewController 中.错误出来.未知类型名称" ViewController "，您是说" UIViewController "吗?
Has try import in AViewController
in BViewController
. error come out. unknown type name'ViewController', did you mean 'UIViewController'?
如果我也想访问AViewController，该如何解决.
If i want access the AViewController too, how do i solve this.
外面的任何人都可以帮助我，在此先谢谢您.
Anyone out there can help me, thank you in advance.
推荐答案
在您的BViewController.h
In your BViewController.h
#import AViewcontroller.h
@property(nonatomic,retain) AViewcontroller* aViewcontroller;
在您的BViewController.m
In your BViewController.m
@synthesis aViewcontroller;
然后在AViewcontroller.m中创建BViewcontroller对象的地方，说bViewcontroller
Then in your AViewcontroller.m where you create your BViewcontroller object lets say bViewcontroller
bViewcontroller.aViewcontroller=self;
//then navigate to bViewcontroller
然后，您可以在BViewController的方法中更新以前的AViewController的标签文本.
Then you can update the previous AViewController's label text inside BViewController 's method.
self.aViewcontroller.label_you_want_to_update.text=@"your_text_here";
