樓主主要接觸了倆種更新方式，一種是服務器端配置，app直接獲取到服務器返回的version值，同本地的version比較，如果本地的小于返回值，則更新（優點：服務器可自行控制是否為強制更新或者普通更新，缺點：由于App Store審核的不確定性，服務器端不能及時配置version，【樓主用這種方式上傳了好幾次，都被拒】）第二種是根據app的id來更新，使用蘋果的lookup接口來實現，這種可以繞開蘋果的審核，同時由于和我們自己的服務器沒有多大關系，導致無法配置更新方式（即：強制更新或非強制更新）
首先我們來看第一種更新方式
NSString *softversion = [[[NSBundle mainBundle] infoDictionary] objectForKey:(NSString *)kCFBundleVersionKey];
softversion = [softversion stringByReplacingOccurrencesOfString:@"." withString:@""];
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT,0), ^{
NSString *urlstring = [NSString stringWithFormat:APPVERURL,MAINJIYUNURL,REQUESTTYPE,VERSION,APPVERSION];
//對可能出現的英文處理
urlstring = [urlstring stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSURL *url = [NSURL URLWithString:urlstring];
NSString *string = [[NSString alloc] initWithData:[NSData dataWithContentsOfURL:url] encoding:NSUTF8StringEncoding];
id data = [string JSONValue];
dispatch_async(dispatch_get_main_queue(), ^{
if (data && [data isKindOfClass:[NSDictionary class]])
{
if(data && [data isKindOfClass:[NSDictionary class]])
{
NSDictionary * dict = (NSDictionary *)data;
NSNumber *numflg = [dict objectForKey:@"flag"];
if (numflg && [numflg intValue] == 1)
{
NSData*data=[dict[@"version_content"] dataUsingEncoding:NSUTF8StringEncoding ];
NSDictionary*dic=[NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:nil];
NSString * curVer = [dic objectForKey:@"IOSnewVersion"];
NSString * minVer = [dic objectForKey:@"ios_forceUpdate"];
NSString * updateurl = [dic objectForKey:@"ios_update_url"];
NSString * updatedesc = [dic objectForKey:@"update_desc"];
NSString * bkcruver;
bkcruver = curVer;
self.update_url = updateurl;//直接到App Store更新
curVer = [curVer stringByReplacingOccurrencesOfString:@"." withString:@""];
minVer = [minVer stringByReplacingOccurrencesOfString:@"." withString:@""];
int softver = [softversion intValue];
int ncurver = [curVer intValue];
newVersion=ncurver;
int nminver = [minVer intValue];
// 先判斷是否是有效的版本號
if ( (softver >= 100 && softver <= 999) &&
(ncurver >= 100 && ncurver <= 999))
{
NSString * title = [NSString stringWithFormat:@"發現新版本 v%@",bkcruver];
NSString * message = updatedesc;
// 需要更新
if(ncurver > softver)
{
// 提示該版本已經不能使用，要使用，強制更新
if(nminver == 1)
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title message:message delegate:self cancelButtonTitle:@"立即更新" otherButtonTitles:nil] ;
alert.tag = 247;
[alert show];
}
// 只是提醒更新
else
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title message:message delegate:self cancelButtonTitle:@"稍后再說" otherButtonTitles:@"立即更新",nil] ;
alert.tag = 246;
[alert show];
}
}
}
}
else {
}
}
}
});
});
第二種更新方式
//1先獲取當前工程項目版本號
NSDictionary *infoDic = [[NSBundle mainBundle] infoDictionary];
NSLog(@"infoDic -- %@",infoDic);
NSString *currentVersion = infoDic[@"CFBundleShortVersionString"];
//2從網絡獲取appStore版本號
//STOREAPPID為AppStore的應用id
NSData *response = [NSURLConnection sendSynchronousRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://itunes.apple.com/cn/lookup?id=%@",STOREAPPID]]] returningResponse:nil error:nil];
if (response == nil) {
NSLog(@"網絡連接失敗");
return;
}
NSDictionary *appInfoDic = [NSJSONSerialization JSONObjectWithData:response options:NSJSONReadingMutableLeaves error:&error];
NSLog(@"appInfoDic -- %@",appInfoDic);
NSArray *array = appInfoDic[@"results"];
if (array.count < 1) {
NSLog(@"app未找到");
return;
}
NSDictionary *dic = array[0];
NSString *appStoreVersion = dic[@"version"];
//打印版本號
NSLog(@"當前版本號:%@\n商店版本號:%@",currentVersion,appStoreVersion);
//設置版本號
currentVersion = [currentVersion stringByReplacingOccurrencesOfString:@"." withString:@""];
if (currentVersion.length==2) {
currentVersion = [currentVersion stringByAppendingString:@"0"];
}else if (currentVersion.length==1){
currentVersion = [currentVersion stringByAppendingString:@"00"];
}
appStoreVersion = [appStoreVersion stringByReplacingOccurrencesOfString:@"." withString:@""];
if (appStoreVersion.length==2) {
appStoreVersion = [appStoreVersion stringByAppendingString:@"0"];
}else if (appStoreVersion.length==1){
appStoreVersion = [appStoreVersion stringByAppendingString:@"00"];
}
//3當前版本號小于商店版本號,就更新
if([currentVersion floatValue] < [appStoreVersion floatValue])
{
UIAlertController *alercConteoller = [UIAlertController alertControllerWithTitle:@"版本有更新" message:[NSString stringWithFormat:@"檢測到新版本(%@),是否更新?",dic[@"version"]] preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *actionYes = [UIAlertAction actionWithTitle:@"更新" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
//此處加入應用在app store的地址，方便用戶去更新，一種實現方式如下
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"https://itunes.apple.com/us/app/id%@?ls=1&mt=8", STOREAPPID]];
[[UIApplication sharedApplication] openURL:url];
}];
UIAlertAction *actionNo = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:^(UIAlertAction * _Nonnull action) {
}];
[alercConteoller addAction:actionYes];
[alercConteoller addAction:actionNo]; //如果強制更新去掉取消按鈕，不是強制更新的時候需要加上取消按鈕
[self.window.rootViewController presentViewController:alercConteoller animated:YES completion:nil];
}else{
NSLog(@"版本號大于商店版本號不需要更新");
}
親測第一種更新方式會被拒，第二種更新方式可以通過審核??????
