iOS APP版本升级

1.获取appStore的APP数据//获取appStore版本号

#pragma mark -- 获取appStore的APP数据 // 获取appStore版本号- (void)PostpathAPPStoreVersion{// 这是获取appStore上的app的版本的urlNSString*appStoreUrl = [[NSStringalloc] initWithFormat:@"http://itunes.apple.com/lookup?id=%@",@"这里填app在appStore的id号"];NSURL*url = [NSURLURLWithString:appStoreUrl];NSMutableURLRequest*request = [NSMutableURLRequestrequestWithURL:url                                                          cachePolicy:NSURLRequestReloadIgnoringCacheDatatimeoutInterval:10];    [request setHTTPMethod:@"POST"];NSOperationQueue*queue = [NSOperationQueuenew];    [NSURLConnectionsendAsynchronousRequest:request queue:queue completionHandler:^(NSURLResponse*response,NSData*data,NSError*error){NSMutableDictionary*receiveStatusDic=[[NSMutableDictionaryalloc]init];if(data) {NSDictionary*receiveDic = [NSJSONSerializationJSONObjectWithData:data options:NSJSONReadingMutableLeaveserror:nil];if([[receiveDic valueForKey:@"resultCount"] intValue]>0) {                [receiveStatusDic setValue:@"1"forKey:@"status"];                [receiveStatusDic setValue:[[[receiveDic valueForKey:@"results"] objectAtIndex:0] valueForKey:@"version"]  forKey:@"version"];            }else{                [receiveStatusDic setValue:@"-1"forKey:@"status"];            }        }else{            [receiveStatusDic setValue:@"-1"forKey:@"status"];        }        [selfperformSelectorOnMainThread:@selector(receiveData:) withObject:receiveStatusDic waitUntilDone:NO];    }];}

下面的 sender[@"version"] 就是获取的版本号 注意是String类型的

2  . 比较appStore的app版本号和本地的app的版本号

-(void)receiveData:(id)sender{NSDictionary*infoDictionary = [[NSBundlemainBundle] infoDictionary];// 手机当前APP软件版本  比如：1.0.2NSString*nativeVersion = [infoDictionary objectForKey:@"CFBundleShortVersionString"];NSString*storeVersion  = sender[@"version"];    DEBUGLog(@"本地版本号curV=%@", nativeVersion);    DEBUGLog(@"商店版本号appV=%@", sender[@"version"]);NSComparisonResultcomparisonResult = [nativeVersion compare:storeVersion options:NSNumericSearch];//NSOrderedSame相同 NSOrderedAscending = -1L表示升序;  NSOrderedDescending = +1 表示降序UIAlertView*alertv = [[UIAlertViewalloc]initWithTitle:@"有新版本是否更新"message:nildelegate:selfcancelButtonTitle:@"取消"otherButtonTitles:@"确定",nil];switch(comparisonResult) {caseNSOrderedSame:            DEBUGLog(@"本地版本与商店版本号相同，不需要更新");break;caseNSOrderedAscending:            DEBUGLog(@"本地版本号 < 商店版本号相同，需要更新");            [alertv show];break;caseNSOrderedDescending:            DEBUGLog(@"本地版本号 > 商店版本号相同，不需要更新");break;default:break;    }}

顺便把检测可能用到的其他信息也贴一下吧

pragma mark --检测版本等信息

- (void)PhoneAppVersionInfomations{NSString* identifierNumber = [[UIDevicecurrentDevice].identifierForVendor UUIDString] ;    DEBUGLog(@"手机序列号: %@",identifierNumber);//手机别名： 用户定义的名称NSString* userPhoneName = [[UIDevicecurrentDevice] name];    DEBUGLog(@"手机别名: %@", userPhoneName);//设备名称NSString* deviceName = [[UIDevicecurrentDevice] systemName];    DEBUGLog(@"设备名称: %@",deviceName );//手机系统版本NSString* phoneVersion = [[UIDevicecurrentDevice] systemVersion];    DEBUGLog(@"手机系统版本: %@", phoneVersion);//手机型号NSString* phoneModel = [[UIDevicecurrentDevice] model];    DEBUGLog(@"手机型号: %@",phoneModel );//地方型号  （国际化区域名称）NSString* localPhoneModel = [[UIDevicecurrentDevice] localizedModel];    DEBUGLog(@"国际化区域名称: %@",localPhoneModel );NSDictionary*infoDictionary = [[NSBundlemainBundle] infoDictionary];// 当前应用名称NSString*appCurName = [infoDictionary objectForKey:@"CFBundleDisplayName"];    DEBUGLog(@"当前应用名称：%@",appCurName);// 当前应用软件版本  比如：1.0.1NSString*appCurVersion = [infoDictionary objectForKey:@"CFBundleShortVersionString"];    DEBUGLog(@"当前应用软件版本:%@",appCurVersion);// 当前应用版本号码  int类型NSString*appCurVersionNum = [infoDictionary objectForKey:@"CFBundleVersion"];    DEBUGLog(@"当前应用版本号码：%@",appCurVersionNum);}
