前言：一直APP集成更新功能我们在会被拒，但是最近发现很多APP都弹出了更新提示。并且产品也希望有此功能，所以特意去了解，并App加入更新提示功能。
1. app更新检测功能是否会被拒？
苹果是有明确的规定是：app更新检测是会被拒的。 但是个人总结：苹果的规定是：app内不许出现去更新，或检测更新的确切操作（例如Android：app设置里面检测更新功能）。结论是：可以根据去APP store 里面的更新状态，与本地版本对比，然后弹出更新提示。 为保险：审核期间根据服务端控制，隐藏检测更新功能。
2. 功能实现
1. 获取App Store 本app的信息
请求http://itunes.apple.com/cn/lookup?id=908915361，地址即可。
/cn ,cn是中国的标准，因为itunes有区分国际，所以必须在链接那加上cn。
id是appId， 从itunes -> APP信息 -> Apple ID 获得。
请求结果：

}
trackViewUrl：常规方式下跳转AppStore的链接。
version：最新的版本号。
trackId：应用内模态AppStore需要的应用id。
APPReleaseNotes：应用更新的内容。
2.AppStore的跳转方式
- 跳到appstrore
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:trackViewUrl]];
- 模态弹窗
#import <StoreKit/StoreKit.h>
//初始化和赋值操作、设置代理
SKStoreProductViewController *storeViewController = [[SKStoreProductViewController alloc] init];
storeViewController.delegate = self;
NSDictionary *parametersDic = @{SKStoreProductParameterITunesItemIdentifier:[userDefault objectForKey:TRACK_ID]};
[storeViewController loadProductWithParameters:parametersDic completionBlock:^(BOOL result, NSError * _Nullable error) {
if (result) {
[[UIApplication sharedApplication].keyWindow.rootViewController presentViewController:storeViewController animated:YES completion:^{
}];
}
}];
//代理方法
- (void)productViewControllerDidFinish:(SKStoreProductViewController *)viewController {
[[UIApplication sharedApplication].keyWindow.rootViewController dismissViewControllerAnimated:YES completion:^{
}];
}
3. 集成pods
已有一个框架AYCheckVersion https://github.com/AYJk/AYCheckVersion 已经实现相应功能。原理懂后，直接集成即可。
pod 加入 ：
pod 'AYCheckVersion'
用法 ：
AYCheckManager *checkManger = [AYCheckManager sharedCheckManager];
[checkManger checkVersion];
使用默认属性进行版本的检测。
- (void)checkVersion;
自定义警示框的标题，下次提示的标题，立即更新的标题。
- (void)checkVersionWithAlertTitle:(NSString *)alertTitle nextTimeTitle:(NSString *)nextTimeTitle confimTitle:(NSString *)confimTitle;
自定义警示框的标题，下次提示的标题，立即更新的标题，跳过该版本的标题。
- (void)checkVersionWithAlertTitle:(NSString *)alertTitle nextTimeTitle:(NSString *)nextTimeTitle confimTitle:(NSString *)confimTitle skipVersionTitle:(NSString *)skipVersionTitle;
如果你想在当前应用中以模态视图的形式打开AppStore，请设置openAPPStoreInsideAPP，默认从应用跳转出去到AppStore。
checkManger.openAPPStoreInsideAPP = YES;
