iOS不添加任何信息检测App更新

一.前言:

  • 1.iOS开发中,有时会有这种需求,在AppStore上出现新版本时,应用内弹窗提示用户更新.
  • 2.之前在网上看到一种方法通过AppId查询更新的,但是有时候APP没上线或开发账号还没注册下来时我们并不知道AppId,此时就要把这个功能做上去,该怎么办呢?
  • 3.现介绍一种简便的方法给大家,不需要提供AppId等任何信息,即可实现查询AppStore中是否有新版本,并提示更新.
  • 4.代码地址:见篇尾.

二.效果:

三.实现逻辑:

  • 1.先查询AppStore中该App的信息(包含版本,更新日志等)
  • 2.和App当前版本进行比较,比当前版本新,弹窗并显示更新日志,提示用户跳转到AppStore更新
  • 3.为了方便在以后开发中调用,笔者实现时进行简单封装.

四.直接上代码:

-4.1获取AppStore中该App的版本信息

  • 1.为了不依赖其他数据请求库,笔者采用系统方法做数据请求,当然你们也可以使用AFN等框架请求数据.
  • 2.新建一个请求版本信息的类继承NSObject笔者取名 XHVersionRequest
  • 3.在XHVersionRequest.h文件中添加请求成功和失败回调和数据请求方法,代码如下:

#import <Foundation/Foundation.h>

typedef void(^RequestSucess) (NSDictionary * responseDict);
typedef void(^RequestFailure) (NSError *error);

@interface XHVersionRequest : NSObject

/**
 *  从AppStore中获取App信息
 *
 *  @param success 成功回调
 *  @param failure 失败回调
 */
+(void)xh_versionRequestSuccess:(RequestSucess)success failure:(RequestFailure)failure;

@end

复制代码
  • 4.在XHVersionRequest.m文件中实现

#import "XHVersionRequest.h"

@implementation XHVersionRequest
+(void)xh_versionRequestSuccess:(RequestSucess)success failure:(RequestFailure)failure{
    
    NSDictionary *infoDict = [[NSBundle mainBundle] infoDictionary];
    NSString *bundleId = infoDict[@"CFBundleIdentifier"];
    NSURL *URL = [NSURL URLWithString:[NSString stringWithFormat:@"http://itunes.apple.com/lookup?bundleId=%@",bundleId]];
    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
       
        NSURLRequest *request = [NSURLRequest requestWithURL:URL];
        NSURLSessionDataTask *dataTask = [[NSURLSession sharedSession] dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
            
            dispatch_async(dispatch_get_main_queue(), ^{
                
                if(!error)
                {
                    NSDictionary *responseDict = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableLeaves error:nil];
                    if(success) success(responseDict);
                }
                else
                {
                    if(failure) failure(error);
                }
                
            });

        }];
        
        [dataTask resume];

    });

}
@end

-4.2解析请求回来App信息数据

  • 1.新建一个App信息模型继承NSObject,笔者取名XHAppInfo,为减少依赖,笔者暂不采用JSON -> Model 框架解析数据.

  • 2.在XHAppInfo.h和XHAppInfo.m中分别添加以下代码:

  • XHAppInfo.h文件


#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>

@interface XHAppInfo : NSObject

/**
 *  版本号
 */
@property(nonatomic,copy) NSString * version;

/**
 *  更新日志
 */
@property(nonatomic,copy)NSString *releaseNotes;

/**
 *  更新时间
 */
@property(nonatomic,copy)NSString *currentVersionReleaseDate;

/**
 *  APPId
 */
@property(nonatomic,copy)NSString *trackId;

/**
 *  bundleId
 */
@property(nonatomic,copy)NSString *bundleId;

/**
 *  AppStore地址
 */
@property(nonatomic,copy)NSString *trackViewUrl;

- (instancetype)initWithResult:(NSDictionary *)result;

@end

复制代码
  • XHAppInfo.m文件
#import "XHAppInfo.h"

@implementation XHAppInfo

- (instancetype)initWithResult:(NSDictionary *)result{
    
    self = [super init];
    if (self) {
        
        self.version = result[@"version"];
        self.releaseNotes = result[@"releaseNotes"];
        self.currentVersionReleaseDate = result[@"currentVersionReleaseDate"];
        self.trackId = result[@"trackId"];
        self.bundleId = result[@"bundleId"];
        self.trackViewUrl = result[@"trackViewUrl"];
    }
    return self;
}
@end

复制代码

-4.3比较与当前版本大小关系,提示更新

  • 1.笔者新建一个类XHVersion(继承NSObject)来处理版本比较和弹窗

  • 2.为了调用更灵活,我们在XHVersion.h文件中添加如下两个方法:1.一个是使用默认弹窗,2.一个是回调新版本信息,开发者自定义弹窗

  • XHVersion.h文件

#import <Foundation/Foundation.h>
#import "XHAppInfo.h"

typedef void(^NewVersionBlock)(XHAppInfo *appInfo);

@interface XHVersion : NSObject

/**
 *  检测新版本(使用默认提示框)
 */
+(void)checkNewVersion;

/**
 *  检测新版本(自定义提示框)
 *
 *  @param newVersion 新版本信息回调
 */
+(void)checkNewVersionAndCustomAlert:(NewVersionBlock)newVersion;

@end

复制代码
  • XHVersion.m文件中进行实现,代码如下

#import "XHVersion.h"
#import "XHVersionRequest.h"

@interface XHVersion()<UIAlertViewDelegate>

@property(nonatomic,strong)XHAppInfo *appInfo;

@end

@implementation XHVersion

+(void)checkNewVersion{
    
    [[XHVersion shardManger] checkNewVersion];
}
+(void)checkNewVersionAndCustomAlert:(NewVersionBlock)newVersion{
    
    [[XHVersion shardManger] checkNewVersionAndCustomAlert:newVersion];
}

#pragma mark - private

+(XHVersion *)shardManger{
    
    static XHVersion *instance = nil;
    static dispatch_once_t oneToken;
    dispatch_once(&oneToken,^{
        
        instance = [[XHVersion alloc] init];
        
    });
    return instance;
}
-(void)checkNewVersion{
    
    [self versionRequest:^(XHAppInfo *appInfo) {
    
        NSString *updateMsg = [NSString stringWithFormat:@"%@",appInfo.releaseNotes];
#if __IPHONE_OS_VERSION_MIN_REQUIRED < __IPHONE_8_0
        UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"发现新版本" message:updateMsg delegate:self cancelButtonTitle:@"关闭" otherButtonTitles:@"更新", nil];
        [alertView show];
#endif
      
#if __IPHONE_OS_VERSION_MIN_REQUIRED >= __IPHONE_8_0
        UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"发现新版本" message:updateMsg preferredStyle:UIAlertControllerStyleAlert];
        [alert addAction:[UIAlertAction actionWithTitle:@"关闭" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {

        }]];
        [alert addAction:[UIAlertAction actionWithTitle:@"更新" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {

            [self openInAppStoreForAppURL:self.appInfo.trackViewUrl];
            
        }]];
        
        [[self window].rootViewController presentViewController:alert animated:YES completion:nil];
#endif
        
    }];

}
-(UIWindow *)window{
    
    UIWindow *window = nil;
    id<UIApplicationDelegate> delegate = [[UIApplication sharedApplication] delegate];
    if ([delegate respondsToSelector:@selector(window)]) {
        window = [delegate performSelector:@selector(window)];
    } else {
        window = [[UIApplication sharedApplication] keyWindow];
    }
    return window;
}
-(void)checkNewVersionAndCustomAlert:(NewVersionBlock)newVersion{
    
    [self versionRequest:^(XHAppInfo *appInfo) {
        
        if(newVersion) newVersion(appInfo);
        
    }];
}
-(void)versionRequest:(NewVersionBlock)newVersion{
    
    [XHVersionRequest xh_versionRequestSuccess:^(NSDictionary *responseDict) {
        
        NSInteger resultCount = [responseDict[@"resultCount"] integerValue];
        if(resultCount==1)
        {
            NSArray *resultArray = responseDict[@"results"];
            NSDictionary *result = resultArray.firstObject;
            XHAppInfo *appInfo = [[XHAppInfo alloc] initWithResult:result];
            NSString *version = appInfo.version;
            self.appInfo = appInfo;
            if([self isNewVersion:version])//新版本
            {
                if(newVersion) newVersion(self.appInfo);
            }
        }
        
    } failure:^(NSError *error) {
        
    }];

}

#if __IPHONE_OS_VERSION_MIN_REQUIRED < __IPHONE_8_0
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
    
    if(buttonIndex==1)
    {
        [self openInAppStoreForAppURL:self.appInfo.trackViewUrl];
    }
}
#endif

-(void)openInAppStoreForAppURL:(NSString *)appURL{
    
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:appURL]];
}

- (void)productViewControllerDidFinish:(SKStoreProductViewController *)viewController {
    
    [viewController dismissViewControllerAnimated:YES completion:nil];
}

//是否是新版本
-(BOOL)isNewVersion:(NSString *)newVersion{
    
    return [self newVersion:newVersion moreThanCurrentVersion:[self currentVersion]];
}
-(NSString * )currentVersion{
    
    NSString *key = @"CFBundleShortVersionString";
    NSString * currentVersion = [NSBundle mainBundle].infoDictionary[key];
    return currentVersion;
}
-(BOOL)newVersion:(NSString *)newVersion moreThanCurrentVersion:(NSString *)currentVersion{
    
    if([currentVersion compare:newVersion options:NSNumericSearch]==NSOrderedAscending)
    {
        return YES;
    }
    return NO;
}

复制代码

五.调用:

  • 导入头文件 #import "XHVersion.h" ,在需要检测新版本的地方调用下面代码
    
     //1.新版本检测(使用默认提示框)
     [XHVersion checkNewVersion];
    
     //2.如果你需要自定义提示框,请使用下面方法
     [XHVersion checkNewVersionAndCustomAlert:^(XHAppInfo *appInfo) {
        
        //appInfo为新版本在AppStore相关信息
        //请在此处自定义您的提示框
        //......
    }];

复制代码

六.小结:

  • 细看代码的同学可能会发现,笔者并没有通过AppId去拉取该App的版本信息,而是通过bundleId去查询的.
