如何将NSString发送到另一个视图控制器 [英] How to send an NSString to another view controller

问题描述

我有一个IBAction，当触发时调用另一个视图控制器中的另一个方法（APICallsViewController）。我也希望将该方法发送给NSString（消息）

I have an IBAction that when triggered calls another method in a different view controller ( APICallsViewController). I'm looking to also send that method an NSString (message)

这里是我的IBAction，推送到APICallsViewController以及NSString消息。我的问题可能是如何在其他视图控制器的方法中获取该NSString的内容。

here's my IBAction with the push to the APICallsViewController and also the NSString message. My question might be how do I grab the contents of that NSString in the other view controller's method.

感谢您的帮助

-(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];

}

推荐答案

这样做APICallsViewController.h中的代码

do this code in APICallsViewController.h

@interface APICallsViewController : UIViewController{
   NSString *strMessage;

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

@end

APICallsViewController.m

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];

}
