一、系统支持自动更新
首先iOS系统中是支持APP的自动更新的，可以开关选择
二、APP内部提示更新
若用户没有选择打开自动更新，择APP中提示更新。可以在用户进入APP首页后进行提示，具体逻辑如下
- 请求Apple Store上的版本信息
- 与本地version版本号进行对比
- 进行跳转到Apple store下载页面
1、请求Apple store上的版本信息
- (void)getAppleStoreVersionInfo:(void(^)(NSString *version, NSString *releaseNotes))successBlock {
NSInteger appid = @"Apple store上的Appid";
NSString *urlString = [NSString stringWithFormat:@"http://itunes.apple.com/cn/lookup?id=%li",appid];
[WhzxRequest requestGetWithURL:urlString success:^(NSDictionary * _Nullable resultDictionary, NSURLResponse * _Nullable response) {
NSString *newVersion = [resultDictionary[@"results"]firstObject][@"version"];
NSString *releaseNotes = [resultDictionary[@"results"]firstObject][@"releaseNotes"];
if (successBlock) {
successBlock(newVersion, releaseNotes);
}
} failure:^(NSError * _Nullable error) {
}];
}
得到了线上的版本号、版本更新等信息，具体的信息如下表

2、与本地版本号进行对比
获取本地版本号
+ (NSString *)getVersionNumber {
NSString *version = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"];
return version;
}
判断版本对比
//判断当前版本和Apple store版本
if ([appCurrentVersion compare:appStoreVersion options:NSNumericSearch] == NSOrderedAscending) {
[self showVersionUpdateViewWithInfoDic:releaseNotes];
}
3、进行跳转到Apple store下载页面
NSURL *url = [NSURL URLWithString:AppleStoreURL];
//前往苹果商店更新
[[UIApplication sharedApplication] openURL:url options:@{} completionHandler:nil];
