如何在不同故事板中的视图控制器之间发送数据

Question

这是我在第一个viewcontroller.m文件中的代码：

RiskViewController *riskVC = [[RiskViewController alloc] initWithNibName:nil bundle:[NSBundle mainBundle]];
riskVC.Address1 = @"THIS IS THE DATA IM TRYING TO SEND!";
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle: [NSBundle mainBundle]];
[self.navigationController pushViewController:[storyboard instantiateViewControllerWithIdentifier:@"Risk"] animated:YES];

这是我在第二个viewcontroller.h文件中的代码：

@interface RiskViewController : UIViewController <UITextFieldDelegate>

@property (nonatomic, strong) NSString * Address1;

这是我在第二个viewcontroller.m文件中的代码。它是NSLoging，self.Address1为null：

- (void)viewDidLoad {
[super viewDidLoad];
NSLog(@"Addy1%@", self.Address1);
}

为什么我的self.Address1字符串为null，它应该包含我发送的字符串，如何解决此问题以便发送数据？

Answer 1

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle: [NSBundle mainBundle]];
RiskViewController *riskVC = [storyboard instantiateViewControllerWithIdentifier:@"Risk"]
riskVC.Address1 = @"THIS IS THE DATA IM TRYING TO SEND!";
[self.navigationController pushViewController:riskVC animated:YES];
