Question

好的，所以我基本上都遵循了这个链接中的教程 http://www.techotopia.com/index.php/An_iOS_7_In-App_Purchase_Tutorial 我也试过这个教程：How do you add an in-app purchase to an iOS application?但它对我不起作用。如果有人帮助我，我会非常感激。我将使用第一个链接，因为这是我使用的教程。它适用于应用程序购买中的一个，但是，我如何在应用程序购买中进行更多操作？更多关卡？本教程只教一个，所以我尝试按照相同的教程，但通过更改名称，它仍然无法正常工作。我得到的最接近的是它确实购买它，但即使我连接奥特莱斯也没有启用按钮。需要帮助，编码如下：

ViewController.h

enter code here#import <UIKit/UIKit.h>
#import <StoreKit/StoreKit.h>
#import "PurchaseViewController.h"
#import "SecondPurchaseViewController.h"

@interface MAGViewController : UIViewController

- (IBAction)purchaseItem:(id)sender;
@property (strong, nonatomic) IBOutlet UIButton *level2Button;
@property (strong, nonatomic) PurchaseViewController *purchaseController;

- (IBAction)SecondpurchaseItem:(id)sender;
@property (strong, nonatomic) IBOutlet UIButton *level3Button;
@property (strong, nonatomic) SecondPurchaseViewController *SecondpurchaseController;


-(void)enableLevel2;
-(void)enableLevel3;
@end

.m文件是:(我确实把#import“PurchaseViewController.h”放了，所以不是那样，我也放第二个。

- (IBAction)purchaseItem:(id)sender {

_purchaseController.productID =
@"com.example.IAP.courseone";

[self.navigationController
 pushViewController:_purchaseController animated:YES];

[_purchaseController getProductInfo: self];
}

- (IBAction)SecondpurchaseItem:(id)sender {

    _SecondpurchaseController.SecondproductID =
    @"com.example.IAP.coursetwo";

    [self.navigationController
     pushViewController:_SecondpurchaseController animated:YES];

    [_SecondpurchaseController getSecondProductInfo: self];
}

-(void)enableLevel2
{
    _level2Button.enabled = YES;
}

-(void)enableLevel3
{
    _level3Button.enabled = YES;
}


- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.

    _purchaseController = [[PurchaseViewController alloc]init];

    [[SKPaymentQueue defaultQueue]
     addTransactionObserver:_purchaseController];

    //

    _SecondpurchaseController = [[SecondPurchaseViewController alloc]init];

    [[SKPaymentQueue defaultQueue]
     addTransactionObserver:_SecondpurchaseController];
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

PurchaseViewController.h是

#import <UIKit/UIKit.h>
#import <StoreKit/StoreKit.h>

@interface PurchaseViewController : UIViewController <SKPaymentTransactionObserver, SKProductsRequestDelegate>

@property (strong, nonatomic) IBOutlet UILabel *productTitle;
@property (strong, nonatomic) IBOutlet UITextView *productDescription;
@property (strong, nonatomic) IBOutlet UIButton *buyButton;
- (IBAction)buyProduct:(id)sender;


@property (strong, nonatomic) SKProduct *product;
@property (strong, nonatomic) NSString *productID;

- (void)getProductInfo:(UIViewController *)viewController;

@end

PurchaseViewController.m是：

@interface PurchaseViewController ()
@property (strong, nonatomic) MAGViewController *homeViewController;
@end


@implementation PurchaseViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];

如何让它适用于多个IAP购买？ ray wenderlick教程在表视图中显示，但我不想要表视图，我想要自定义背景的自定义按钮，所以这个教程很棒，但我不知道如何使它工作不止一个iap。如果你知道答案，请提前感谢你，请评论。我已经挣扎了两天多了。

Answer 1

在.h文件中添加此方法。

 + (RageIAPHelper *)sharedInstance;

在实施文件.m

中

+ (RageIAPHelper *)sharedInstance {
  static dispatch_once_t once;
  static RageIAPHelper * sharedInstance;
  dispatch_once(&once, ^{
      NSSet * productIdentifiers = [NSSet setWithObjects:
                                  @"com.razeware.inapprage.drummerrage",
                                  @"com.razeware.inapprage.itunesconnectrage",
                                  @"com.razeware.inapprage.nightlyrage",
                                  @"com.razeware.inapprage.studylikeaboss",
                                  @"com.razeware.inapprage.updogsadness",
                                  nil];
      sharedInstance = [[self alloc] initWithProductIdentifiers:productIdentifiers];
   });
  return sharedInstance;
}

通过这个我们可以获得更多的productIdentifiers。
