最近因项目需求,需要用到强制更新功能,网上搜了一下,挺多的,但是把网上的代码拷贝以后,发现一个bug,就是进app,弹出框显示,点击现在升级,跳转到appstore下载里面,但是我不下载,又切回到app里面,发现弹出框就不跳了,其实也简单,就是appdelegate里面有个代理方法,就是当app从后台切到前台走的方法,将强制更新方法在这里面在调用一下就行了~~~话不多说,上代码!!!用的话直接粘贴复制~

效果图:

ios实现app强制更新功能

在appdelegate里面写下面代码

  //提示版本更新
 [self versonupdate];
#pragma mark ------提示用户版本更新------

-(void)versonupdate{

  //定义app地址
  nsstring *urld = [nsstring  stringwithformat:@"http://itunes.apple.com/lookup?id=%d",1178114725];

  nsurl *url = [nsurl urlwithstring:urld];

  nsmutableurlrequest *request = [nsmutableurlrequest requestwithurl:url cachepolicy:nsurlrequestreloadignoringcachedata timeoutinterval:10];

  [request sethttpmethod:@"post"];

  nsurlsession *session = [nsurlsession sharedsession];

  nsurlsessiondatatask *task = [session datataskwithurl:url completionhandler:^(nsdata * _nullable data, nsurlresponse * _nullable response, nserror * _nullable error) {

    nslog(@"%@",response);

    nsmutabledictionary *receivestatusdic = [[nsmutabledictionary alloc]init];

    if (data) {

      nsdictionary *receivedic = [nsjsonserialization jsonobjectwithdata:data options:nsjsonreadingmutableleaves error:nil];
      if ([[receivedic valueforkey:@"resultcount"] intvalue] > 0) {

        [receivestatusdic setobject:@"1" forkey:@"status"];

        [receivestatusdic setobject:[[[receivedic valueforkey:@"results"] objectatindex:0] valueforkey:@"version"]  forkey:@"version"];

        [self performselectoronmainthread:@selector(receivedata:) withobject:receivestatusdic waituntildone:no];


      }else{

        [receivestatusdic setvalue:@"1" forkey:@"status"];


      }
    }else{


      [receivestatusdic setvalue:@"-1" forkey:@"status"];
    }


  }];

  [task resume];

}
-(void)receivedata:(id)sender
{
  //获取app自身版本号
  nsstring *localversion = [[[nsbundle mainbundle]infodictionary]objectforkey:@"cfbundleshortversionstring"];

  nsarray *localarray = [localversion componentsseparatedbystring:@"."];//1.0
  nsarray *versionarray = [sender[@"version"] componentsseparatedbystring:@"."];//3 2.1.1


//  if ((versionarray.count == 2) && (localarray.count == versionarray.count)) {

    if ([localarray[0] intvalue] < [versionarray[0] intvalue]) {

      [self updateversion];

    }else if ([localarray[0] intvalue] == [versionarray[0] intvalue]){
      if ([localarray[1] intvalue] < [versionarray[1] intvalue]) {
        [self updateversion];

      }else if ([localarray[1] intvalue] == [versionarray[1] intvalue]){
        if ([localarray[2] intvalue] < [versionarray[2] intvalue]) {

          [self updateversion];

        }
      }
    }
//  }

}

-(void)updateversion{

  nsstring *msg = [nsstring stringwithformat:@"版本过低,需要升级到最新版本"];
  uialertcontroller *alertcontroller = [uialertcontroller alertcontrollerwithtitle:@"升级提示" message:msg preferredstyle:uialertcontrollerstylealert];
  uialertaction *otheraction = [uialertaction actionwithtitle:@"现在升级" style:uialertactionstyledestructive handler:^(uialertaction*action) {

    nsurl *url = [nsurl urlwithstring:[nsstring stringwithformat:@"https://itunes.apple.com/cn/app/m-help/id1178114725?mt=8"]];
    [[uiapplication sharedapplication]openurl:url];
  }];
  [alertcontroller addaction:otheraction];
  [self.window.rootviewcontroller presentviewcontroller:alertcontroller animated:yes completion:nil];

}
//当app从后台切到前台时调用的方法
- (void)applicationdidbecomeactive:(uiapplication * )application
{
  [self versonupdate];
}
