In - App Purchase
1) Import Storekit Framework :
-StoreKit.framework
Note :- Turn This ON
2) Create This Four File In Project :

* RageIAPHelper ( IAPHelper File )

3) Write Code in AppDelegate :
#import "RageIAPHelper.h"
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{

return YES;
}
4) Write Code in ViewController :
* ViewController ( Implement In-App Purchase )
ViewController.h :
#import "RageIAPHelper.h"
#import <StoreKit/StoreKit.h>
- (void)viewDidLoad
{
[super viewDidLoad];
[self reload];

}];
//--------------- call method Which You Want After Payment
// [self sendRequest] ;
}
- (void)reload {
_products = nil;
[[RageIAPHelper sharedInstance] requestProductsWithCompletionHandler:^(BOOL success, NSArray *products) {
if (success) {
_products = products;
}
}];
}
//--------------- 3 Methods Of Payment Here
1 )
- (IBAction)paymentOK:(id)sender
{
SKProduct *product;
for (SKProduct *thisProduct in _products) {
if ([thisProduct.productIdentifier isEqualToString:didselectCatInAppID]) {

}
}
NSLog(@"Buying %@...", product.productIdentifier);
[[RageIAPHelper sharedInstance] buyProduct:product];
}
2 )
- (IBAction)paymentOK:(id)sender
{
[[RageIAPHelper sharedInstance] buyProductIdentifier:didselectCatInAppID];
}
3 )
- (IBAction)paymentOK:(id)sender
{

NSLog(@"Buying %@...", product.productIdentifier);

}
