iOS导入其他APP下载的文件（用其他应用打开）

今天给自己的APP新增了一个小功能可以打开iOS其他APPTXT 文件，一个很小的功能，做阅读APP的小伙伴不要错过。

附上APP地址：一阅阅读

有想看小说的小伙伴可以试下支持换源支持自定义书源

效果如下

1.编辑info.plst

<key>CFBundleDocumentTypes</key>

<array>

    <dict>

        <key>CFBundleTypeIconFiles</key>

        <array>

            <string>icon.png</string>

            <string>icon@2x.png</string>

        </array>

        <key>CFBundleTypeName</key>

        <string>com.myapp.common-data</string>

        <key>LSItemContentTypes</key>

        <array>

        //我只导入txt 所以只加了text

            <string>public.text</string>

//以下区域是我查到的但是我没有加

            <string>public.data</string>

        <string>com.microsoft.powerpoint.ppt</string>

            <string>public.item</string>

            <string>com.microsoft.word.doc</string>

            <string>com.adobe.pdf</string>

            <string>com.microsoft.excel.xls</string>

            <string>public.image</string>

            <string>public.content</string>

            <string>public.composite-content</string>

            <string>public.archive</string>

            <string>public.audio</string>

            <string>public.movie</string>

        </array>

    </dict>

</array>

2.在APPdelegate接收文件地址

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {

    if (self.window) {

        if (url) {

            NSString *fileName = url.lastPathComponent; // 从路径中获得完整的文件名（带后缀）

            // path 类似这种格式：file:///private/var/mobile/Containers/Data/Application/83643509-E90E-40A6-92EA-47A44B40CBBF/Documents/Inbox/jfkdfj123a.pdf

            NSString *path = url.absoluteString; // 完整的url字符串

            path = [self URLDecodedString:path]; // 解决url编码问题

            NSMutableString *string = [[NSMutableString alloc] initWithString:path];

            if ([path hasPrefix:@"file://"]) { // 通过前缀来判断是文件

                // 去除前缀：/private/var/mobile/Containers/Data/Application/83643509-E90E-40A6-92EA-47A44B40CBBF/Documents/Inbox/jfkdfj123a.pdf

                [string replaceOccurrencesOfString:@"file://" withString:@"" options:NSCaseInsensitiveSearch range:NSMakeRange(0, path.length)];

                // 此时获取到文件存储在本地的路径，就可以在自己需要使用的页面使用了

                NSDictionary *dict = @{@"fileName":fileName,

                                       @"filePath":string};

            [[NSNotificationCenter defaultCenter] postNotificationName:TJBookStackWillImportTXTNotification object:nil userInfo:dict];

                return YES;

            }

        }

    }

    return YES;

}

// 当文件名为中文时，解决url编码问题

- (NSString *)URLDecodedString:(NSString *)str {

    NSString *decodedString=(__bridge_transfer NSString *)CFURLCreateStringByReplacingPercentEscapesUsingEncoding(NULL, (__bridge CFStringRef)str, CFSTR(""), CFStringConvertNSStringEncodingToEncoding(NSUTF8StringEncoding));

    return decodedString;

}

3.在主页面对接收到的数据进行处理

不建议在APPdelegate进行处理会拖慢进入APP速度

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(addLoacalBookWithFilePath:) name:TJBookStackWillImportTXTNotification object:nil];

-(void)addLoacalBookWithFilePath:(NSNotification *)notification{

    [SVProgressHUD showInfoWithStatus:@"正在后台解析书籍"];

//启动线程进行处理

    dispatch_queue_t conCurrentQueue = dispatch_queue_create("importBook", DISPATCH_QUEUE_CONCURRENT);

        dispatch_async(conCurrentQueue, ^{

            NSDictionary *dic = notification.userInfo;

            NSString *filePath = dic[@"filePath"];

            NSString *bookId = [NSString stringWithFormat:@"%@", @([[NSDate date] timeIntervalSince1970] * 1000)];

            [TJReadParser parseLocalBookWithFilePath:filePath bookId :bookId success:^(NSArray<TJChapterModel *> * _Nonnull chapters) {

                    // 创建书籍模型

                    TJBookModel *bookModel = [[TJBookModel alloc] init];

                    bookModel.bookType = TJBookTypeLocal;

                    bookModel.bookName = filePath.lastPathComponent;

                    // 本地书随机生成ID

                    bookModel.bookId = bookId;

                    bookModel.chapterCount = chapters.count;

                    for (TJChapterModel *chapter in chapters) {

                        chapter.bookId = bookModel.bookId;

                    }

                    [TJReadHelper addToBookStackWithBook:bookModel complete:^{

                        [TJChapterDataManager insertChaptersWithModels:chapters];

                        [SVProgressHUD showSuccessWithStatus:@"书籍已经成功加入书架"];

                        [[NSNotificationCenter defaultCenter] postNotificationName:TJBookStackDidChangeNotification object:nil userInfo:nil];

                    }];

                } failure:^(NSError *error) {

                    [SVProgressHUD showErrorWithStatus:error.userInfo[NSUnderlyingErrorKey]];

                }];

        });

}

4.更新页面UI

记得回归线程

 dispatch_async(dispatch_get_main_queue(), ^{

        self.dataSource = [[TJReadRecordManager allBooksInStack] copy];

        [self.booksTableView reloadData];

    });
