iOS内购(iap)

通过苹果应用程序商店有三种主要赚钱的方式:

1.直接收费(我想天朝的大多数人是不会购买的)
2.广告 iAd Framework
3.内购:应用程序本身的增值产品,(比如什么欢乐豆之类的)
一般式37开, 苹果3,开发商7

内购的产品分类:

1>非消耗品(Nonconsumable)一旦购买,终身拥有(终身会员)
2>消费品(Consumable),买了就用,用了就没有了(欢乐豆)
剩下三种不常用:(中国用不上 iBooks)
3>免费订阅
4>自动续费订阅
5>非自动续费订阅

内购流程, 苹果官方说明:

添加StoreKit框架,进行内购流程的书写:

#import "ViewController.h"
#import <StoreKit/StoreKit.h>

@interface ViewController () <SKProductsRequestDelegate, SKPaymentTransactionObserver>

/** 所有的产品 */
@property (nonatomic, strong) NSArray *products;

@end

@implementation ViewController

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    
    // 通过观察者监听交易状态
    [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
}

- (void)viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated];
    
    [[SKPaymentQueue defaultQueue] removeTransactionObserver:self];
}

- (void)viewDidLoad {
    [super viewDidLoad];
    
    // 向苹果服务器请求可卖的商品
    [self requestProducts];
    
    self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"恢复" style:UIBarButtonItemStyleDone target:self action:@selector(restore)];
}

/**

{
    // 1.请求所有的商品
    NSString *productFilePath = [[NSBundle mainBundle] pathForResource:@"iapdemo.plist" ofType:nil];
    NSArray *products = [NSArray arrayWithContentsOfFile:productFilePath];
    
    // 2.获取所有的productid
    NSArray *productIds = [products valueForKeyPath:@"productId"];
    
    // 3.获取productid的set(集合中)
    NSSet *set = [NSSet setWithArray:productIds];
    
    // 4.向苹果发送请求,请求可卖商品
    SKProductsRequest *request = [[SKProductsRequest alloc] initWithProductIdentifiers:set];
    request.delegate = self;
    [request start];
}

/**
 *  当请求到可卖商品的结果会执行该方法
 *
 *  @param response response中存储了可卖商品的结果
 */
- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response
{
    /*
    for (SKProduct *product in response.products) {

广告: 苹果自己搞的内容

1.添加iAd.framework
2.添加ADBannerView视图,并设置代理方法
3.广告条加载完成之前最好隐藏

-
(void)bannerViewDidLoadAd:(ADBannerView
*)banner {

    self.bannerBottomConstraint.constant
= 20.0;    

    [UIView
animateWithDuration:0.5
animations:^{

        [self.view
layoutIfNeeded];

    }];   

    NSLog(@"加载广告成功");

}

-
(void)bannerView:(ADBannerView
*)banner didFailToReceiveAdWithError:(NSError
*)error {

    NSLog(@"加载广告失败
%@",
error);

}
