关于iPhone：从Xib将UIViewController加载到UIStoryboard中的另一个UIViewController上

Load UIViewController on another UIViewController in UIStoryboard from xib

我有一个UIViewController(说A)。一个单独的nib文件被加载为该视图控制器上的弹出窗口。当通过单击UIButton关闭弹出窗口时，我想在UIStoryBoard中加载另一个视图控制器(说B)。所有的UIViewControllers都在情节提要中。

我尝试了代表模式。委托方法将self.storyboard返回为nil。

请建议如何处理(从A到B进行表演或从nib文件在导航控制器上推送B的新实例)

这是我用于委托的代码：

**In CustomViewNewPrescription.h file:**

@class CustomViewNewPrescription;
@protocol CustomViewNewPrescriptionDelegate <NSObject>
-(void)SaveCustomViewNewPrescription;
@end
@interface CustomViewNewPrescription : UIView{
id<CustomViewNewPrescriptionDelegate>delegate;

}

@property(nonatomic,strong) id<CustomViewNewPrescriptionDelegate>delegate;

**in .m:**
- (IBAction)btnCancel:(UIButton *)sender{
[self.delegate SaveCustomViewNewPrescription];
}

delegate was synthesized and initialised.

**In AddNewRx.h:**
@interface AddNewRx : UIViewController<CustomViewNewPrescriptionDelegate>{
}

**in AddNewRx.m:**

-(void)SaveCustomViewNewPrescription{
//either self performseguewithidentifier .... (or)
RxViewController *obj1 = [[self.navigationController storyboard] instantiateViewControllerWithIdentifier:@"RxViewController"];
[self.navigationController pushViewController:obj1 animated:YES];
}

在SaveCustomViewNewPrescription中，self.storyboard给出nil值

请建议如何在SaveCustomViewNewPrescription中加载另一个视图控制器。

代替：

1	RxViewController *obj1 = [[self.navigationController storyboard] instantiateViewControllerWithIdentifier:@"RxViewController"];

尝试：

1 2	UIStoryboard yourStoryboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil]; RxViewController obj1 = [yourStoryboard instantiateViewControllerWithIdentifier:@"RxViewController"];
