IOS APP检测更新

APPStore上架应用：

第三方库：QJCheckVersionUpdate

核心代码：

+ (void)CheckVerion:(UpdateBlock)updateblock
{
    NSString *storeString = [NSString stringWithFormat:@"https://itunes.apple.com/lookup?bundleId=%@",OLDVERSION];
    NSURL *storeURL = [NSURL URLWithString:storeString];
    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:storeURL];
    [request setHTTPMethod:@"GET"];
    NSOperationQueue *queue = [[NSOperationQueue alloc] init];
    [NSURLConnection sendAsynchronousRequest:request queue:queue completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
        if ( [data length] > 0 && !error ) {
            // Success
            NSDictionary *appData = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:nil];
            dispatch_async(dispatch_get_main_queue(), ^{
                // All versions that have been uploaded to the AppStore
                NSArray *versionsInAppStore = [[appData valueForKey:@"results"] valueForKey:@"version"];
                /**
                 *  以上网络请求可以改成自己封装的类
                 */
                if(![versionsInAppStore count]) {
                    NSLog(@"No versions of app in AppStore");
                    return;
                } else {
                    NSString *currentAppStoreVersion = [versionsInAppStore objectAtIndex:0];
                    NSLog(@"%@",OLDVERSION);
                    if ([QJCheckVersionUpdate versionlessthan:[GetUserDefaut isKindOfClass:[NSString class]] && GetUserDefaut ? GetUserDefaut : OLDVERSION Newer:currentAppStoreVersion])
                    {
                        NSLog(@"暂不更新");
                    }else{
                        NSLog(@"请到appstore更新%@版本",currentAppStoreVersion);
                        /**
                         *  修复问题描述
                         */
                        NSString *describeStr = [[[appData valueForKey:@"results"] valueForKey:@"releaseNotes"] objectAtIndex:0];
                        NSLog(@"修复问题描述:%@",describeStr);
                        NSArray *dataArr = [QJCheckVersionUpdate separateToRow:describeStr];
                        if (updateblock) {
                            updateblock(currentAppStoreVersion,dataArr);
                        }
                    }
                }
                
            });
        }
        
    }];
}

版本比较

+ (BOOL)versionlessthan:(NSString *)oldOne Newer:(NSString *)newver
{
    if ([oldOne isEqualToString:newver]) {
        return YES;
    }else{
        if ([oldOne compare:newver options:NSNumericSearch] == NSOrderedDescending)
        {
            return YES;
        }else{
            return NO;
        }
    }
    return NO;
}

 

 

企业INhouse打包的App:

1.方式一：

后台写段代码，记录版本号，每次更新手动修改版本号。

2.方式二：

解析plist。因为打包的时候plist里存着版本号

代码如下：

-(void)updateApp{
    NSDictionary* dict = [NSDictionary dictionaryWithContentsOfURL:[NSURL URLWithString:@"http://你服务器上plist的地址/Picc.plist"]];
   
    if (dict) {
      
        NSArray* list = [dict objectForKey:@"items"];
        NSDictionary* dict2 = [list objectAtIndex:0];
    
        NSDictionary* dict3 = [dict2 objectForKey:@"metadata"];
        NSString* newVersion = [dict3 objectForKey:@"bundle-version"];
        
      //  NSLog(@"版本号%@",dict4);
      
        NSDictionary *infoDict = [[NSBundle mainBundle] infoDictionary];
        NSString *myVersion = [infoDict objectForKey:@"CFBundleShortVersionString"];
        
        if (![newVersion isEqualToString:myVersion]) {
            UIAlertView* alert = [[UIAlertView alloc] initWithTitle:@"提示" message:@"有新版本" delegate:self cancelButtonTitle:@"马上去更新" otherButtonTitles:@"暂不更新", nil];
            [alert showWithCompletionHandler:^(NSInteger buttonIndex) {
                if (buttonIndex ==0) {
                    NSLog(@"更新");
                    NSLog(@"%@",DOWNLOAD);
                      [[UIApplication sharedApplication] openURL:[NSURL URLWithString:DOWNLOAD]];
                }
                else if(buttonIndex ==1){
                    NSLog(@"不更新");
                }
            }];
        }
        else{
            UIAlertView * aler = [[UIAlertView alloc] initWithTitle:@"提示" message:@"您已经是最新版" delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil, nil];
            [aler show];
        }
        
        
        
    }
    else{
        UIAlertView* alert = [[UIAlertView alloc] initWithTitle:@"提示" message:@"请检查网络" delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil, nil];
        [alert show];
    }
        
}
