通過蘋果應用程式商店有三種主要賺錢的方式:

1.直接收費(我想天朝的大多數人是不會購買的)
2.廣告 iAd Framework
3.內購:應用程式本身的增值產品,(比如什麼歡樂豆之類的)
一般式37開, 蘋果3,開發商7

內購的產品分類:

1>非消耗品(Nonconsumable)一旦購買,終身擁有(終身會員)
2>消費品(Consumable),買了就用,用了就沒有了(歡樂豆)
剩下三種不常用:(中國用不上 iBooks)
3>免費訂閱
4>自動續費訂閱
5>非自動續費訂閱

內購流程, 蘋果官方說明:

新增StoreKit框架,進行內購流程的書寫:

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

@interface ViewController () <SKProductsRequestDelegate, SKPaymentTransactionObserver>

/** 所有的產品 */
@property (nonatomic, strong) NSArray *products;

@end

@implementation ViewController

- (void)viewWillAppear:(BOOL)animated
{
    [super
 
 viewWillAppear:animated];

    // 通過觀察者監聽交易狀態
    [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
}

- (void)viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated];

    [[SKPaymentQueue defaultQueue] removeTransactionObserver:self];
}

- (void)viewDidLoad {
    [super
 
 viewDidLoad];

    // 向蘋果伺服器請求可賣的商品
    [self requestProducts];

    self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"恢復" style:UIBarButtonItemStyleDone target:self action:@selector(restore)];
}

/**
 *  請求可賣商品
 */
- (void)requestProducts
{
    // 1.請求所有的商品
    NSString *productFilePath = [[NSBundle mainBundle] pathForResource:@"iapdemo.plist" ofType:nil];
    NSArray *products = [NSArray arrayWithContentsOfFile:productFilePath];

    // 2.獲取所有的productid
    NSArray *productIds = [products valueForKeyPath:@"productId"];

    // 3.獲取productid的set(集合中)
    NSSet *set = [NSSet setWithArray:productIds];

    // 4.向蘋果傳送請求,請求可賣商品
    SKProductsRequest *request = [[SKProductsRequest alloc] initWithProductIdentifiers:set];
    request.delegate = self;
    [request start];
}

/**
 *  當請求到可賣商品的結果會執行該方法
 *
 *  @param response response中儲存了可賣商品的結果
 */
- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response

    }

    // 1.取出模型
    SKProduct *product = self.products[indexPath.row];

    // 2.給cell設定資料
    cell.textLabel.text = product.localizedTitle;
    cell.detailTextLabel.text = [NSString stringWithFormat:@"價格:%@", product.price];

    return cell;

    [[SKPaymentQueue defaultQueue] restoreCompletedTransactions];

廣告: 蘋果自己搞的內容

1.新增iAd.framework
2.新增ADBannerView檢視,並設定代理方法
3.廣告條載入完成之前最好隱藏

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

    self.bannerBottomConstraint.constant
= 20.0;    

    [UIView
animateWithDuration:0.5
animations:^{

        [self.view
layoutIfNeeded];

    }];   

    NSLog(@"載入廣告成功");

}

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

    NSLog(@"載入廣告失敗
%@",
error);

}
