先上代碼
//1. 在application中調用
-(void)checkVersionUpdata{
NSString *urlStr = @"http://itunes.apple.com/lookup?id=1329918420";//id替換即可
NSURL *url = [NSURL URLWithString:urlStr];
NSURLRequest *req = [NSURLRequest requestWithURL:url];
[NSURLConnection connectionWithRequest:req delegate:self];
}
//2. 網絡連接
-(void)connection:(NSURLConnection *)connection didReceiveData:(nonnull NSData *)data
{
NSError *error;
id jsonObject = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:&error];
[XKCEHint disMissLoading];
NSDictionary *appInfo = (NSDictionary*)jsonObject;
NSArray *infoContent = [appInfo objectForKey:@"results"];
NSString * version = [[infoContent objectAtIndex:0]objectForKey:@"version"];//線上最新版本
// 獲取當前版本
NSString *currentVersion = [self version];//當前用戶版本
BOOL result = [currentVersion compare:version] == NSOrderedAscending;
if (result) {//需要更新
[XKCEGlobleData sharedData].version = @"1";
NSLog(@"不是最新版本需要更新");
NSString *updateStr = [NSString stringWithFormat:@"發現新版本V%@\n為保證軟件的正常運行\n請及時更新到最新版本",version];
[self creatAlterView:updateStr];
} else {//已經是最新版；
NSLog(@"最新版本不需要更新");
}
}
//3. 彈框提示
-(void)creatAlterView:(NSString *)msg{
UIAlertController *alertText = [UIAlertController alertControllerWithTitle:@"更新提醒" message:msg preferredStyle:UIAlertControllerStyleAlert];
//增加按鈕
[alertText addAction:[UIAlertAction actionWithTitle:@"我再想想" style:UIAlertActionStyleCancel handler:^(UIAlertAction *action) {
}]];
[alertText addAction:[UIAlertAction actionWithTitle:@"立即更新" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
NSString *str = @"itms-apps://itunes.apple.com/cn/app/id1329918420?mt=8"; //更換id即可
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:str]];
}]];
[self.window.rootViewController presentViewController:alertText animated:YES completion:nil];
}
//版本
-(NSString *)version
{
NSDictionary *infoDictionary = [[NSBundle mainBundle] infoDictionary];
NSString *app_Version = [infoDictionary objectForKey:@"CFBundleShortVersionString"];
return app_Version;
}
1. url只要替換成自己的id即可
2. jsonobject中可以獲取到當前軟件在APPstore的信息,返回的內容大致如下
{
resultCount = 1;
results = (
{
artistId = 開發者 ID;
artistName = 開發者名稱;
price = 0;
isGameCenterEnabled = 0;
kind = software;
languageCodesISO2A = (
EN
);
trackCensoredName = 審查名稱;
trackContentRating = 評級;
trackId = 應用程序 ID;
trackName = 應用程序名稱";
trackViewUrl = 應用程序介紹網址;
userRatingCount = 用戶評級;
userRatingCountForCurrentVersion = 1;
version = 版本號;
wrapperType = software;
}
);
}
我們需要的就是版本信息，將當前版本與AppStore獲取的版本相對比，查看是否是最新版本
3. 彈框提示
跳轉到APPstore的url可以直接將id替換。
