ios-UIAlertView按鈕到其他視圖控制器

UIAlertView按鈕到其他視圖控制器

在應用中有一個uialertview，有兩個按鈕，第一個是取消按鈕，另一個是OK按鈕，在按下OK按鈕時，應該跳到一個帶有storyboard標志符的視圖控制器RootView。應該怎麼實現？

- (void)showAlarm:(NSString *)text {
        UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"show alarm"
                                                            message:text delegate:self                                                  cancelButtonTitle:@"cancel"
                                                  otherButtonTitles:@"ok", nil];
        [alertView show];
    }
    - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
        if (buttonIndex == 0){
             NSLog(@"cancel"); 
        }else if (buttonIndex == 1){
             NSLog(@"ok");
           UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone" bundle:[NSBundle mainBundle]];
           UINavigationController *navigationController = [storyboard instantiateViewControllerWithIdentifier:@"navigationController"];
            [navigationController presentViewController:[storyboard instantiateViewControllerWithIdentifier:@"RootView"] animated:YES completion:nil];
   }
    }

最佳回答：

可嘗試在當前控制器中，彈出identifier為navigationController的控制器，在navigationController控制器中再push到rootView.改成這樣試試

 UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone" bundle:[NSBundle mainBundle]];
    UINavigationController *navigationController = [storyboard instantiateViewControllerWithIdentifier:@"navigationController"];
if (navigationController) {
   [self presentViewController:navigationController animated:YES completion:nil];
}

接著在identifier 為navigationcontroller的控制器的viewwillappear中push到rootview

-(void)viewWillAppear {
     RootViewController *rootController=[storyboard instantiateViewControllerWithIdentifier:@"RootView"];

     if (rootController) {
            [self.navigationController pushViewController:rootController animation:NO];
     }
}
