ios 版本更新提示

    苹果审核中如果发现项目中有版本更新提示,将禁止上架,那么我们可以让后台传一个字段,上架前后修改一下即可,或者通过下面的方式,判断当前版本和线上版本的大小,如果当前版本小于线上版本则弹出提示,否则不提示,这样苹果审核的时候就不发发现了,同时不需要后台传入字段,进行判断,当然这种方法是已知自己的app id的情况下才可以的,下面介绍一下直接对比版本号的方法

    @implementation UpdateVersion
    + (instancetype)shareVersionUpdateManage {
        static UpdateVersion *instance = nil;
        staticdispatch_once_t onceToken;
        dispatch_once(&onceToken, ^{
            instance = [[selfalloc] init];
       });
        return instance;
    }
    
    - (void)versionUpdate{
        //获得当前发布的版本   
    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT,0), ^{
            //耗时的操作---获取某个应用在AppStore上的信息,更改id就行
            NSString *string = [NSStringstringWithContentsOfURL:[NSURLURLWithString:@"http://itunes.apple.com/lookup?id=00000000000"]encoding:NSUTF8StringEncodingerror:nil];
            NSData *data = [string dataUsingEncoding:NSUTF8StringEncoding];
          // 判断是否取到信息
            if (![data isKindOfClass:[NSDataclass]]) {
                return ;
            }
            NSDictionary *dic = [NSJSONSerializationJSONObjectWithData:data options:NSJSONReadingMutableLeaveserror:nil];
            //获得上线版本号
            NSString *version = [[[dic objectForKey:@"results"]firstObject]objectForKey:@"version"];
            NSString *updateInfo = [[[dic objectForKey:@"results"]firstObject]objectForKey:@"releaseNotes"];
            //获得当前版本
         NSString *currentVersion = [[[NSBundlemainBundle]infoDictionary]objectForKey:@"CFBundleShortVersionString"];
    
            
    
            // 将线上版本和当前版本转化成int型
            int versionInt = [[version stringByReplacingOccurrencesOfString:@"."withString:@""] intValue];
            int currentVersionInt = [[currentVersion stringByReplacingOccurrencesOfString:@"."withString:@""] intValue];      dispatch_async(dispatch_get_main_queue(), ^{
            //更新界面
                NSLog(@"线上版本:%d 当前版本:%d",versionInt,currentVersionInt);
                if (versionInt > currentVersionInt) {
                    //有新版本
                    NSString *message = [NSStringstringWithFormat:@"有新版本发布啦!\n%@",updateInfo];
                    UIAlertView *alertView = [[UIAlertViewalloc]initWithTitle:@"温馨提示"message:message delegate:selfcancelButtonTitle:@"忽略"otherButtonTitles:@"前往更新",nil];
                    [alertView show];
                }else{
                    //已是最高版本
                    NSLog(@"已经是最高版本");
                }
            });
        });
    }
    
    然后在根控制器中,调用一下方法
    - (void)checkVersion{
        NSString *netWorkingState = [PublicMethod networkingStatesFromStatebar];
        if ([netWorkingState  isEqual: @"notReachable"]) {
            LYLog(@"当前无网络连接");
        }else{
            [[CRUpdateVersion shareVersionUpdateManage] versionUpdate];
        }
    }
    
    

    2、以上为已上线项目的更新,这样做有个风险,很可能会在审核的时候被检测到有版本更新的代码,所以安全起见,还是使用从后台获取数据比较好

    新建一个工具类
    @interface JFApplication : NSObject
    @property (nonatomic, strong)AFNetworkReachabilityManager* networkManager;
    - (void)checkAppVersionOnCompletion:(void (^)(JFVersionResponse *))completion;
    
    
    
    // .m中实现
    - (void)checkAppVersionOnCompletion:(void (^)(JFVersionResponse *))completion {
        if (_checkingVersion) {
            return;
        }
        _checkingVersion = YES;
        __weak typeof(self) weakSelf = self;
        JFVersionRequest *request = [[JFVersionRequest alloc] init];
        [[JFNetworkManager sharedManager] post:request forResponseClass:[JFVersionResponse class] success:^(WXResponse *response) {
            _checkingVersion = NO;
            [weakSelf handleVersionResponse:(JFVersionResponse *)response];
            if(completion){
                completion((JFVersionResponse *)response);
            }
        } failure:^(NSError *error) {
            _checkingVersion = NO;
            if (completion) {
                completion(nil);
            }
        }];
    }
    
    - (void)handleVersionResponse:(JFVersionResponse *)response {
        if ([response success]) {
            JFVersion * version = response.data;
            if([JFVersion isNewVersion:version.version]) {
                NSMutableString *message = [NSMutableString string];
                for (int i = 0;i < version.releaseLog.count;i++) {
                    NSString *item = version.releaseLog[i];
                    [message appendString:item];
                    if (i != version.releaseLog.count - 1) {
                        [message appendString:@"\n"];
                    }
                }
                [[WXAlert sharedAlert] showConfirmMessage:message withTitle:kStr(@"New Version") cancelButtonTitle:kStr(@"Cancel") okButtonTitle:kStr(@"Download") onCompletion:^(NSInteger buttonIndex, UIAlertView *alertView) {
                    if (buttonIndex == 1) {
                        kOpenURL(version.releaseUrl);
                    }
                }];
            }
        }
    }
    
    

    2.2 所需的模型类

    #import "JFResponse.h"
    #import "JFVersion.h"
    
    @interface JFVersionResponse : JFResponse
    @property(nonatomic,strong)JFVersion *data;
    @end
    
    #import "JFVersionResponse.h"
    
    @implementation JFVersionResponse
    
    @end
    
    
    #import "WXObject.h"
    
    @interface JFVersion : WXObject
    @property(nonatomic,copy)NSString *version;//版本号
    @property(nonatomic,copy)NSString *name;
    @property(nonatomic,copy)NSString *releaseTime;//版本发布时间
    @property(nonatomic,copy)NSString *releaseUrl;//版本获取地址
    @property(nonatomic,strong)NSArray *releaseLog;//版本简要日志
    
    + (BOOL) isNewVersion:(NSString *)version;
    @end
    
    #import "JFVersion.h"
    
    @implementation JFVersion
    
    + (BOOL) isNewVersion:(NSString *)version {
        if([NSString isNullOrEmpty:version]){
            return NO;
        }
        NSArray *versions = [version splitBy:@"."];
        if(!versions || versions.count==0){
            return NO;
        }
        NSArray *currentVerions = [kAppVersion splitBy:@"."];
        if(!currentVerions || currentVerions.count==0){
            return NO;
        }
        for(int i=0,n=(int)MIN(versions.count, currentVerions.count);i<n;i++){
            int v = [[currentVerions objectAtIndex:i] getIntValue];
            int v2 = [[versions objectAtIndex:i] getIntValue];
            if(v<v2){
                return YES;
            }
            if(v>v2) {
                return NO;
            }
        }
        if (versions.count>currentVerions.count) {
            for (NSInteger i=currentVerions.count; i<versions.count; i++) {
                int v = [[versions objectAtIndex:i] getIntValue];
                if (v>0) {
                    return YES;
                }
            }
        }
        return NO;
    }
    
    @end
    
    - (NSArray*) splitBy:(NSString *)splitString{
        return [self componentsSeparatedByString: splitString];
    }
    
    #define kAppVersion [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"]
    
    
    // 最后在根控制器中调用
    [[JFApplication sharedApplication] checkAppVersionOnCompletion:nil];
    

    以上就是版本更新的方法
    效果如图

    当然,以上都是对于没有重大bug,不需要强制用户更新的情况,如果app有重大bug,必须用户升级才能使用,这时候需要后台加上一个字段,表明是否需要强制用户更新,否则用户无法使用app,这里就不做细致介绍了,加上一个字段,加上一个判断就行
