我是iOS開發新手。我使用Storyboard創建了一個App來導航到不同的頁面。如何使用push Storyboard Segue for NavigationController
當我點擊添加BarButton客戶頁面 - >轉到添加客戶頁面(使用Modal
故事板Segue公司)
在那裏,當我輸入用戶名和密碼,並點擊保存按鈕 - >返回客戶頁面。
一切工作正常。
問題是我想在添加客戶頁面中有back button
。我已經知道我可以使用Push
故事板Segue公司,但是當我使用它,我面對一個錯誤:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Pushing a navigation controller is not supported'
*** First throw call stack:

terminate called throwing an exception(lldb)
CustomerViewController.h:
#import "AddCustomerViewController.h"
@interface CustomerViewController : UITableViewController<AddCustomerViewControllerDelegate>
{
IBOutlet UITableView *tableview;
NSMutableArray *customers;
}
@property(nonatomic,retain)IBOutlet UITableView *tableview;
@property(nonatomic,retain)NSMutableArray *customers;
@end
這是我在CustomerViewController.m使用的代碼:
self.customers = [[NSMutableArray alloc]init];
-(void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if([segue.identifier isEqualToString:@"AddCustomer"])
{
UINavigationController *navigationController = segue.destinationViewController;
AddCustomerViewController *addCustomerViewController = [[navigationController viewControllers] objectAtIndex:0];
addCustomerViewController.delegate = self;
}
}
-(void) addCustomerViewControllerDidSave: (AddCustomerViewController *) Controller newCustomer: (Customer *) customer
{
[self dismissViewControllerAnimated: YES completion:NULL];
[self.customers addObject:customer];
[self.tableview reloadData];
}
AddCustomerViewController.h:
#import "Customer.h"
@class AddCustomerViewController;
@protocol AddCustomerViewControllerDelegate <NSObject>
-(void) addCustomerViewControllerDidSave: (AddCustomerViewController *) Controller newCustomer: (Customer *) customer;
@end
@interface AddCustomerViewController : UITableViewController
{
}
@property (nonatomic, weak) id <AddCustomerViewControllerDelegate> delegate;
@property (nonatomic, strong) IBOutlet UITextField *firstnameTxt;
@property (nonatomic, strong) IBOutlet UITextField *lastnameTxt;
- (IBAction)save:(id)sender;
@end
而且AddCustomerViewController.m:
- (void)save:(id)sender
{
NSLog(@"Save");
Customer *newCustomer = [[Customer alloc]init];
newCustomer.firstname = self.firstnameTxt.text;
newCustomer.lastname = self.lastnameTxt.text;
[self.delegate addCustomerViewControllerDidSave:self newCustomer:newCustomer];
}
你能不能幫我,我怎麼可以使用Push
故事板Segue公司(有後退按鈕)?
是,擺脫第二導航控制器。你如何繼續添加客戶視圖控制器?什麼樣的賽格?這是一種模式嗎? – 2012-08-05 01:12:46
是的,它是莫代爾,它工作正常。 – Ali 2012-08-05 08:51:15
