1.导入头文件<StoreKit/StoreKit.h>
#import <StoreKit/StoreKit.h>
2.将所有内购产品的ID放进一个数组productArr
#define Product1 @"product1" //产品ID
#define Product2 @"product2"
#define Product3 @"product3"
#define Product4 @"product4"
#define Product5 @"product5"
#define Product6 @"product6"
3.加入协议
@interface ViewController ()
<
SKPaymentTransactionObserver,
SKProductsRequestDelegate
>
@property (nonatomic, assign) NSInteger selectedProduct;//选择购买的产品在数组中的序号
@end
@implementation ViewController{
NSArray *productArr; //存放产品ID
}
4.添加一个购买按钮
- (void)viewDidLoad {
[super viewDidLoad];
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[ button setTitle: @"点击购买"forState:UIControlStateNormal];
[button addTarget:self action:@selector(startPayClick:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:button];
//添加一个交易队列观察者
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
productArr = @[Product1,Product2,Product3,Product4,Product5,Product6];
}
pragma mark - Event response 购买按钮点击事件
-(void)startPayClick:(UIButton *)button{
self.selectedProduct = 1;//购买第一个产品
//判断是否可进行支付
if ([SKPaymentQueue canMakePayments]) {
NSLog(@"----------允许程序内付费--------");
[self requestProductData:productArr[self.selectedProduct]];
} else {
NSLog(@"不允许程序内付费");
}
}
pragma mark ---内购测试

//根据商品ID查找商品信息

request.delegate = self;
[request start];
}
