Question

我开发了一个应用程序购买应用程序。我有以下代码...在ViewController.m文件中我是butoon1Clicked方法我是callInAppPurchases。实际上，当我第一次点击按钮时，我想进行In App Purchases。如果事务成功，从下一次单击我想要执行某些操作（例如我给出NSLog语句）我应该在程序中编写NSLog stmt（或任何代码）以便在我单击时执行Action成功交易后的按钮。请在我必须写的地方冒险。或者在任何过程中解释我。我以为我想处理BOOL值，但我不知道我必须将BOOL值设置为YES / NO。请解释一下...... MyStoreObserver.m文件执行In App Purchase Transactions。

ViewController.m

-(IBAction)button1Clicked:(id)sender
{       
     [self callInAppPurchase];
     NSLoG(@"Perform Some Action");
}
#pragma mark-In-AppPurchase code from here
-(void)callInAppPurchase
{
    if ([SKPaymentQueue canMakePayments])
    {
        // Display a store to the user.     
    }
}

AppDelegate.h

#import <UIKit/UIKit.h>
#import "MyStoreAbserver.h"
@interface iTeach_MathsAppDelegate : NSObject <UIApplicationDelegate> 
{
    BOOL isPurchased,isFailed;
}
@property (nonatomic, readwrite) BOOL isPurchased,isFailed;
@property (nonatomic, retain) IBOutlet UIWindow *window;

AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:     (NSDictionary *)launchOptions
{

      MyStoreAbserver *observer = [[MyStoreAbserver alloc] init];
       [[SKPaymentQueue defaultQueue] addTransactionObserver:observer];
      if([[[NSUserDefaults standardUserDefaults] objectForKey:@"isPurchased"] isEqualToString:@"true"])
       self.isPurchased = YES;
     else
       isPurchased = NO;
     isFailed = NO;

// Override point for customization after application launch.
[self.window makeKeyAndVisible];
return YES;
}
