您需要将选定的值传递给下一个视图控制器，并将选定的值设置为导航栏标题。

在视图控制器 2 viewcontroller2.h中创建一个 NSString 实例

@property(nonatomic,retain)NSString *title;

在视图控制器 1 中导航到 viewcontroller2 之前，您需要将所选视图设置为 viewcontroller 2 标题实例（一种将值发送到下一个视图）

视图控制器 1：

ViewController1 *view1 = [[ViewController1 alloc] init];
view1.title = pickerSelectedString;
[self.navigationController pushViewController:view1];
