iOS Перейдите к следующему ViewController

Question

У меня есть контроллер просмотра, который называется PlantingTreeVC. в том, что существует два типа платежных опций: i.e. PaybyCreditCard и PaybyCash. Если пользователь выбирает PaybyCreditCard и нажимает NextButton, он должен перейти к PayPalVC или, если пользователь выберет PaybyCash и нажмите NextButton, он должен перейти к CustomerDetailsVC. Как я могу это сделать?

Мой код ниже:

PlantingTreeVC.h

Answer 1

@interface PlantingTreeVC() 
{ 
    PaybyCreditCard_BOOL,PaybyCash_BOOL 
} 
@end 

    //Other code 

- (IBAction)PayByCardButton:(id)sender{ 
    if(PaybyCreditCard_BOOL){ 
     PaybyCreditCard_BOOL=NO; 
    } 
    else{ 
     PaybyCreditCard_BOOL=YES; 

    //Dont forget this check also 
     if(PaybyCash_BOOL){ 
      PaybyCash_BOOL =NO; 
      } 


     } 

    } 

- (IBAction)PayByCashButton:(id)sender{ 
    if(PaybyCash_BOOL){ 
    PaybyCash_BOOL =NO; 
    } 
    else{ 
    PaybyCash_BOOL =YES; 
//Dont forget this check also 

     if(PaybyCreditCard_BOOL){ 
      PaybyCreditCard_BOOL =NO; 
      } 
    } 
    } 

- (IBAction)NextButton:(id)sender{ 
    if(PaybyCreditCard_BOOL){ 
    //go toPayPalVC 
    } 
    else if(PaybyCash_BOOL){ 

    //go toPayPalCash 
    } 
    else{ 
     } 
    } 

Создайте два bool PaybyCreditCard_BOOL, PaybyCash_BOOL, по умолчанию они установлены на NO.Now, когда кнопка нажата, она переключается на «да» и «нет». См. Приведенный выше код.
