iphone - 如何将 NSString 发送到另一个 View Controller

Question

我有一个 IBAction，它在触发时调用不同 View Controller (APICallsViewController) 中的另一个方法。我还希望向该方法发送 NSString(消息)

这是我的 IBAction 推送到 APICallsViewController 和 NSString 消息。我的问题可能是如何在另一个 View Controller 的方法中获取该 NSString 的内容。

谢谢你的帮助

-(IBAction) someMethod{
        APICallsViewController *apiViewController = [[APICallsViewController alloc] init];
        [self.navigationController pushViewController:apiViewController animated:YES]; 

        NSString *message = [NSString stringWithFormat:@"Check out %@", nameLb.text];

        [apiViewController apiGraphUserCheckins];

        [apiViewController release];

}

在 APICallsViewController.h 中执行此代码

@interface APICallsViewController : UIViewController{
   NSString *strMessage;

}
@property(nonatomic,retain) NSString *strMessage;

@end

APICallsViewController.m

 @synthesize strMessage;

- (void)viewDidLoad {
Nslog(@"%@",strMessage);

---

-(IBAction) someMethod{

    APICallsViewController *apiViewController = [[APICallsViewController alloc] init];
    [self.navigationController pushViewController:apiViewController animated:YES]; 

    NSString *message = [NSString stringWithFormat:@"Check out %@", nameLb.text];
    apiViewController.strMessage=message;
    [apiViewController apiGraphUserCheckins];

    [apiViewController release];

}
