iOS導航下一個ViewController

Question

我有一個名為PlantingTreeVC的視圖控制器。 因為有兩種付款方式，即。 PaybyCreditCard和PaybyCash 。如果用戶選擇PaybyCreditCard並單擊NextButton ，則應導航到PayPalVC或者如果用戶選擇PaybyCash並單擊NextButton ，則應導航到CustomerDetailsVC。 我該怎么做？

我的代碼如下：

PlantingTreeVC.h

#import "ViewController.h"

@interface PlantingTreeVC : ViewController {
    BOOL checked;
}
@property (weak, nonatomic) IBOutlet UIImageView *topStrip;
@property (weak, nonatomic) IBOutlet UIImageView *bgView;

@property (weak, nonatomic) IBOutlet UILabel *commaTextLbl;
@property (weak, nonatomic) IBOutlet UILabel *getPlaqueLbl;

@property (weak, nonatomic) IBOutlet UIScrollView *plantScrollView;
@property (weak, nonatomic) IBOutlet UISwitch *Switch;

@property (weak, nonatomic) IBOutlet UIImageView *giveTreeView;
@property (weak, nonatomic) IBOutlet UISwitch *giveTreeIB;

@property (weak, nonatomic) IBOutlet UILabel *nameLabel;
@property (weak, nonatomic) IBOutlet UILabel *emailLabel;
@property (weak, nonatomic) IBOutlet UILabel *phonenoLabel;

@property (weak, nonatomic) IBOutlet UIImageView *paymentView;
@property (weak, nonatomic) IBOutlet UILabel *payByCardLbl;
@property (weak, nonatomic) IBOutlet UILabel *payByCashLbl;

@property (weak, nonatomic) IBOutlet UIButton *paybyCardIB;
@property (weak, nonatomic) IBOutlet UIButton *payByCashIB;
@property (weak, nonatomic) IBOutlet UIButton *backBtIB;
@property (weak, nonatomic) IBOutlet UIButton *nextBtIB;

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{
      }
  }

創建兩個布爾PaybyCreditCard_BOOL，PaybyCash_BOOL，默認將它們設置為NO。現在，當點擊按鈕時，它將切換為是和否。請參見上面的代碼
