对比版本号一般是为了实现版本更新的功能,弹窗提示用户更新或者直接跳转的App Store。

获取应用在App Store中的版本信息

这里我们使用的是iTunes 的lookup 接口,前提是你已经发布到App Store。

获取应用在App Store中的id

下面是可以获取到App Store中的id 的两种方法

  1. App Store搜索<软件名称>,例如:微信,进入详情页后,点击分享按钮,点击拷贝链接

App Store拷贝链接

  1. 长按已经下载的软件,点击分享App,点击拷贝链接 长按App

找到在App Store这个链接中的idhttps://apps.apple.com/cn/app/%E5%BE%AE%E4%BF%A1/id414478124

获取应用在App Store的版本号

使用AFNetworking的GET请求,请求如下

+ (void)getAppStoreVersionInfoWithResponseBlock:(void (^)(NSDictionary *, NSError *))responseBlock {
    AFHTTPSessionManager *sessionManager = [AFHTTPSessionManager manager];
    [sessionManager.responseSerializer setAcceptableContentTypes: [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript",@"text/html", nil]];
    
    [sessionManager GET:@"https://itunes.apple.com/cn/lookup?id=414478124" parameters:nil progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        NSArray *dataArray = responseObject[@"results"];
        if (dataArray.count != 0) {// 先判断返回的数据是否为空
            NSDictionary *dict = dataArray.firstObject;
            responseBlock(dict, nil);
        } else {
            NSError *emptyError = [[NSError alloc] initWithDomain:NSStringFromClass(self) code:NetWorkResponseCodeAppearError userInfo:@{NSLocalizedDescriptionKey:@"内容为空"}];
            responseBlock(nil, emptyError);
        }
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        responseBlock(nil, error);
    }];
    
}

可以先用Postman先调用下,然后在根据自己的需要来写数据模型。获取到结果后,可以直接取出App Store中的版本号"version": "7.0.8"

本地版本号与App Store版本号的对比

拿微信举例,任何版本(低于、高于、等于App Store版本)点击版本更新按钮都会跳到App Store,我的做法则是做个版本信息的弹窗。

获取本地的版本号

  1. 获取App信息,需要取出Info.plist中包含的信息。
//A dictionary, constructed from the bundle’s Info.plist file, that contains information about the receiver.
- (NSDictionary<NSString *, id> *)appInfoDictionary {
    return [[NSBundle mainBundle] infoDictionary];
}

  1. 取出版本号
- (NSString *)appVersion {
    return [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"];
}

对比

版本号大都是1.0.0这样的,所以需要把每一位都取出来进行对比。

我原来使用的是for-in循环,参考了QMUIKit+ compareSystemVersion: toVersion:方法后,觉得while循环更适合,代码如下

+ (NSComparisonResult)compareSystemVersion:(NSString *)currentVersion toVersion:(NSString *)targetVersion {
    NSArray *currentVersionArr = [currentVersion componentsSeparatedByString:@"."];
    NSArray *targetVersionArr = [targetVersion componentsSeparatedByString:@"."];
    
    NSInteger pos = 0;
    
    while ([currentVersionArr count] > pos || [targetVersionArr count] > pos) {
        NSInteger v1 = [currentVersionArr count] > pos ? [[currentVersionArr objectAtIndex:pos] integerValue] : 0;
        NSInteger v2 = [targetVersionArr count] > pos ? [[targetVersionArr objectAtIndex:pos] integerValue] : 0;
        if (v1 < v2) {
            return NSOrderedAscending;
        }
        else if (v1 > v2) {
            return NSOrderedDescending;
        }
        pos++;
    }
    
    return NSOrderedSame;
}

版本更新完整代码

- (void)p_versionUpdateButtonAction  {
	//获取本地的App版本号
    NSString *appVersion = [VPUtilityTool sharedInstance].appVersion;
	
    [VPMineRequestHandler getAppStoreVersionInfoWithResponseBlock:^(NSDictionary * _Nonnull response, NSError * _Nonnull error) {
        VPLog(@"%@",response);
        if (error) {
		//跳转到App Store详情页中
            [UIApplicationInstance vp_openUrlString:@"https://apps.apple.com/cn/app/%E5%BE%AE%E4%BF%A1/id414478124"];
        } else {
            NSString *appStoreVersion = response[@"version"];
            NSComparisonResult comparisonResult = [QMUIHelper compareSystemVersion:appVersion toVersion:appStoreVersion];
			只要在高于本地版本的结果下才弹窗
            if (comparisonResult == NSOrderedAscending) {
		//更新弹窗
                [AppAlertViewController showWithTitle:@"版本更新" content:[NSString stringWithFormat:@"发现最新版本:V%@\n请到App Store下载更新!", appStoreVersion] cancelButtonTitle:@"取消" confirmButtonTitle:@"更新" actionsHandlerBlock:^(BOOL isCancel) {
                    if (!isCancel) {
                        [UIApplicationInstance vp_openUrlString:@"https://apps.apple.com/cn/app/%E5%BE%AE%E4%BF%A1/id414478124"];
                    }
                }];
            } else {
                [UIApplicationInstance vp_openUrlString:@"https://apps.apple.com/cn/app/%E5%BE%AE%E4%BF%A1/id414478124"];
            }
        }
    }];
	
}


版本更新的功能大概就是以上这么多。
