如何将应用内购买添加到 iOS 应用?所有细节是什么,是否有任何示例代码?
这是关于如何向 iOS 应用程序添加应用程序内购买的各种知识
最佳答案
Swift 用户
Swift 用户可以查看 My Swift Answer for this question .或者,查看 Yedidya Reiss's Answer ,将这段 Objective-C 代码转换为 Swift。
Objective-C 用户
这个答案的其余部分是用 Objective-C 编写的
应用商店连接
My Apps
然后单击您想要添加购买的应用程序到 Features
标题,然后选择 In-App Purchases
左边+
中间的图标 non-consumable
.如果您要向用户发送实物,或者给他们一些他们可以多次购买的东西,您可以选择 consumable
. tld.websitename.appname.referencename
这将最有效,例如,您可以使用 com.jojodmo.blix.removeads
cleared for sale
然后选择价格等级为 1 (99¢)。第 2 层为 1.99 美元,第 3 层为 2.99 美元。如果您单击 view pricing matrix
,可以查看完整列表。我建议您使用第 1 层,因为这通常是任何人为删除广告而支付的最高费用。 add language
按钮,然后输入信息。这将全部显示给客户,所以不要放任何你不想让他们看到的东西 hosting content with Apple

linked frameworks and libraries
单击小加号并添加框架
StoreKit.framework
如果您不这样做,应用内购买将不起作用!
.h
(头)文件通过转到 File
> New
> File...
(命令 ⌘ + N)。在本教程的其余部分,此文件将被称为“您的 .h
文件”.h
文件名为 Bridge.h
在主项目文件夹中,然后转到应用程序管理器(蓝色页面状图标),然后在 Targets
中选择您的应用程序部分,然后单击 Build Settings
.找到显示 的选项Swift 编译器 - 代码生成 ,然后设置 Objective-C 桥接头 选项 Bridge.h
#import "MyObjectiveCHeaderFile.h"
,其中 MyObjectiveCHeaderFile
是您在第一步中创建的头文件的名称。因此,例如,如果您将头文件命名为 InAppPurchase.h ,您将添加行 #import "InAppPurchase.h"
到您的网桥头文件。.m
创建一个新的 Objective-C 方法 ( File
) 文件> New
> File...
(命令 ⌘ + N)。将其命名为您在第 1 步中创建的头文件。例如,如果您在第 1 步中调用该文件 InAppPurchase.h,您将调用此新文件 InAppPurchase.m。在本教程的其余部分,此文件将被称为“您的 .m
文件”。.h
中文件:
BOOL areAdsRemoved;
- (IBAction)restore;
- (IBAction)tapsRemoveAds;
接下来,您需要导入
StoreKit
框架加入您的
.m
文件,以及添加
SKProductsRequestDelegate
和
SKPaymentTransactionObserver
在您的
@interface
之后宣言:
#import <StoreKit/StoreKit.h>
//put the name of your view controller in place of MyViewController
@interface MyViewController() <SKProductsRequestDelegate, SKPaymentTransactionObserver>
@end
@implementation MyViewController //the name of your view controller (same as above)
//the code below will be added here
@end
现在将以下内容添加到您的
.m
中文件,这部分比较复杂,建议大家阅读代码中的注释:
//If you have more than one in-app purchase, you can define both of
//of them here. So, for example, you could define both kRemoveAdsProductIdentifier
//and kBuyCurrencyProductIdentifier with their respective product ids
//
//for this example, we will only use one product
#define kRemoveAdsProductIdentifier @"put your product id (the one that we just made in App Store Connect) in here"
- (IBAction)tapsRemoveAds{
NSLog(@"User requests to remove ads");
if([SKPaymentQueue canMakePayments]){
NSLog(@"User can make payments");
//If you have more than one in-app purchase, and would like
//to have the user purchase a different product, simply define
//another function and replace kRemoveAdsProductIdentifier with
//the identifier for the other product
SKProductsRequest *productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:[NSSet setWithObject:kRemoveAdsProductIdentifier]];
productsRequest.delegate = self;
[productsRequest start];
}
else{
NSLog(@"User cannot make payments due to parental controls");
//this is called the user cannot make payments, most likely due to parental controls
}
}
- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response{
SKProduct *validProduct = nil;
int count = [response.products count];
if(count > 0){
validProduct = [response.products objectAtIndex:0];
NSLog(@"Products Available!");
[self purchase:validProduct];
}
else if(!validProduct){
NSLog(@"No products available");
//this is called if your product id is not valid, this shouldn't be called unless that happens.
}
}
- (void)purchase:(SKProduct *)product{
SKPayment *payment = [SKPayment paymentWithProduct:product];
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
[[SKPaymentQueue defaultQueue] addPayment:payment];
}
- (IBAction) restore{
//this is called when the user restores purchases, you should hook this up to a button
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
}
- (void) paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue
{
NSLog(@"received restored transactions: %i", queue.transactions.count);
for(SKPaymentTransaction *transaction in queue.transactions){
if(transaction.transactionState == SKPaymentTransactionStateRestored){
//called when the user successfully restores a purchase
NSLog(@"Transaction state -> Restored");
//if you have more than one in-app purchase product,
//you restore the correct product for the identifier.
//For example, you could use
//if(productID == kRemoveAdsProductIdentifier)
//to get the product identifier for the
//restored purchases, you can use
//
//NSString *productID = transaction.payment.productIdentifier;
[self doRemoveAds];
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
break;
}
}
}
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions{
for(SKPaymentTransaction *transaction in transactions){
//if you have multiple in app purchases in your app,
//you can get the product identifier of this transaction
//by using transaction.payment.productIdentifier
//
//then, check the identifier against the product IDs
//that you have defined to check which product the user
//just purchased
switch(transaction.transactionState){
case SKPaymentTransactionStatePurchasing: NSLog(@"Transaction state -> Purchasing");
//called when the user is in the process of purchasing, do not add any of your own code here.
break;
case SKPaymentTransactionStatePurchased:
//this is called when the user has successfully purchased the package (Cha-Ching!)
[self doRemoveAds]; //you can add your code for what you want to happen when the user buys the purchase here, for this tutorial we use removing ads
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
NSLog(@"Transaction state -> Purchased");
break;
case SKPaymentTransactionStateRestored:
NSLog(@"Transaction state -> Restored");
//add the same code as you did from SKPaymentTransactionStatePurchased here
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
break;
case SKPaymentTransactionStateFailed:
//called when the transaction does not finish
if(transaction.error.code == SKErrorPaymentCancelled){
NSLog(@"Transaction state -> Cancelled");
//the user cancelled the payment ;(
}
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
break;
}
}
}
现在你想添加你的代码来处理当用户完成交易时会发生什么,在本教程中,我们使用删除添加,你必须为横幅 View 加载时发生的情况添加自己的代码。
- (void)doRemoveAds{
ADBannerView *banner;
[banner setAlpha:0];
areAdsRemoved = YES;
removeAdsButton.hidden = YES;
removeAdsButton.enabled = NO;
[[NSUserDefaults standardUserDefaults] setBool:areAdsRemoved forKey:@"areAdsRemoved"];
//use NSUserDefaults so that you can load whether or not they bought it
//it would be better to use KeyChain access, or something more secure
//to store the user data, because NSUserDefaults can be changed.
//You're average downloader won't be able to change it very easily, but
//it's still best to use something more secure than NSUserDefaults.
//For the purpose of this tutorial, though, we're going to use NSUserDefaults
[[NSUserDefaults standardUserDefaults] synchronize];
}
如果您的应用程序中没有广告,您可以使用任何其他您想要的东西。例如,我们可以将背景的颜色设为蓝色。为此,我们需要使用:
- (void)doRemoveAds{
[self.view setBackgroundColor:[UIColor blueColor]];
areAdsRemoved = YES
//set the bool for whether or not they purchased it to YES, you could use your own boolean here, but you would have to declare it in your .h file
[[NSUserDefaults standardUserDefaults] setBool:areAdsRemoved forKey:@"areAdsRemoved"];
//use NSUserDefaults so that you can load wether or not they bought it
[[NSUserDefaults standardUserDefaults] synchronize];
}
现在,在您的
viewDidLoad
中的某个地方方法,您将要添加以下代码:
areAdsRemoved = [[NSUserDefaults standardUserDefaults] boolForKey:@"areAdsRemoved"];
[[NSUserDefaults standardUserDefaults] synchronize];
//this will load wether or not they bought the in-app purchase
if(areAdsRemoved){
[self.view setBackgroundColor:[UIColor blueColor]];
//if they did buy it, set the background to blue, if your using the code above to set the background to blue, if your removing ads, your going to have to make your own code here
}
现在你已经添加了所有的代码,进入你的
.xib
或
storyboard
文件,并添加两个按钮,一个是购买,另一个是恢复。挂机
tapsRemoveAds
IBAction
到您刚刚制作的购买按钮,以及
restore
IBAction
到恢复按钮。
restore
action 将检查用户之前是否购买了应用内购买,如果他们还没有购买,则免费为他们提供应用内购买。
