```


### Initialize

```objc
if(![IAPShare sharedHelper].iap) {

    NSSet* dataSet = [[NSSet alloc] initWithObjects:@"com.comquas.iap.test", nil];

    [IAPShare sharedHelper].iap = [[IAPHelper alloc] initWithProductIdentifiers:dataSet];

}
```

### Production Mode On/Off

```objc
[IAPShare sharedHelper].iap.production = NO;
```

### Request Products

```objc
[[IAPShare sharedHelper].iap requestProductsWithCompletion:^(SKProductsRequest* request,SKProductsResponse* response)
     {

     }];
```

### Get Locale Price and Title

```objc
SKProduct* product =[[IAPShare sharedHelper].iap.products objectAtIndex:0];

NSLog(@"Price: %@",[[IAPShare sharedHelper].iap getLocalePrice:product]);
NSLog(@"Title: %@",product.localizedTitle);
```

### Purchase

```objc
[[IAPShare sharedHelper].iap buyProduct:product
                                    onCompletion:^(SKPaymentTransaction* trans){
}];
```



### Check Receipt with shared secret

For checking receipt , recommend to use only for server side. I am not recommend to use from client side directly check it. However, sometime we want to use only on client side for some reason. Use with your own risk.

Please check [Apple guide ](https://developer.apple.com/library/content/releasenotes/General/ValidateAppStoreReceipt/Chapters/ValidateRemotely.html#//apple_ref/doc/uid/TP40010573-CH104-SW2).

```objc
[[IAPShare sharedHelper].iap checkReceipt:[NSData dataWithContentsOfURL:[[NSBundle mainBundle] appStoreReceiptURL]] AndSharedSecret:@"your sharesecret" onCompletion:^(NSString *response, NSError *error) {

}];
```

}];
```

### Saving Product Identifier

```objc
[[IAPShare sharedHelper].iap provideContentWithTransaction:transaction];
```

### Check for Previous Purchase

```objc
if([[IAPShare sharedHelper].iap isPurchasedProductsIdentifier:@"com.comquas.iap.test"]
	{
		// require saving product identifier first
	}
```

### Purchased Products

```objc
NSLog(@"%@",[IAPShare sharedHelper].iap.purchasedProducts);
```

### Clear Purchases

```objc
[[IAPShare sharedHelper].iap clearSavedPurchasedProducts];
[[IAPShare sharedHelper].iap clearSavedPurchasedProductByID:@"com.myproduct.id"];
```

### Restore Purchase

```objc
[[IAPShare sharedHelper].iap restoreProductsWithCompletion:^(SKPaymentQueue *payment, NSError *error) {

		//check with SKPaymentQueue

		// number of restore count
		int numberOfTransactions = payment.transactions.count;

		for (SKPaymentTransaction *transaction in payment.transactions)
		{
            NSString *purchased = transaction.payment.productIdentifier;
	        if([purchased isEqualToString:@"com.myproductType.product"])
        	{
				//enable the prodcut here
	        }
    	}

}];
```

## Example

```objc
if(![IAPShare sharedHelper].iap) {
      NSSet* dataSet = [[NSSet alloc] initWithObjects:@"com.comquas.iap.test", nil];

      [IAPShare sharedHelper].iap = [[IAPHelper alloc] initWithProductIdentifiers:dataSet];
  }

[IAPShare sharedHelper].iap.production = NO;

  [[IAPShare sharedHelper].iap requestProductsWithCompletion:^(SKProductsRequest* request,SKProductsResponse* response)
   {
       if(response > 0 ) {
       SKProduct* product =[[IAPShare sharedHelper].iap.products objectAtIndex:0];

        NSLog(@"Price: %@",[[IAPShare sharedHelper].iap getLocalePrice:product]);
        NSLog(@"Title: %@",product.localizedTitle);

        [[IAPShare sharedHelper].iap buyProduct:product
                                  onCompletion:^(SKPaymentTransaction* trans){

              if(trans.error)
              {
                  NSLog(@"Fail %@",[trans.error localizedDescription]);
              }
              else if(trans.transactionState == SKPaymentTransactionStatePurchased) {

                  [[IAPShare sharedHelper].iap checkReceipt:[NSData dataWithContentsOfURL:[[NSBundle mainBundle] appStoreReceiptURL]] AndSharedSecret:@"your sharesecret" onCompletion:^(NSString *response, NSError *error) {

                      //Convert JSON String to NSDictionary
                      NSDictionary* rec = [IAPShare toJSON:response];

                      if([rec[@"status"] integerValue]==0)
                      {
