iOS App文件共享

1.info.plist注册文件类型

在info.plist文件中，添加一个新的属性CFBundleDocumentTypes，这是一个数组类型的属性,这里可以注册等多个类型。

或者在info.plist文件中以Source code的方式添加以下代码：

    CFBundleDocumentTypes
    
        
            CFBundleTypeName
            BIN

或者可以根据自己的需求更改，在这里有文件后缀和 UTI 的对应表,可以查看是否支持文件共享。添加好键值对之后就代表已经成功的注册好了App支持的文件类型，运行Xcode，然后再到第三方App如QQ打开一个QQ不支持打开的文件，会显示用其他应用打开，点击的话会出现系统的弹框：

2.获取共享文件

#define HSFolderName @"Inbox"
- (NSArray *)getAllFile
{
    NSFileManager *fileManager = [NSFileManager defaultManager];
    NSString *path = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) firstObject] stringByAppendingPathComponent:HSFolderName];
    NSArray *files = [fileManager contentsOfDirectoryAtPath:path error:nil];
    NSMutableArray *dataSource = [NSMutableArray array];

    if (files.count < 1) {
        return dataSource;
    }

    for (NSString *fileString in files) {
        FileShareModel *model = [[FileShareModel alloc] init];
        if ([fileString rangeOfString:@".bin"].location !=NSNotFound) {
            model.fileUrl =  [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject] stringByAppendingPathComponent:[NSString stringWithFormat:@"%@/%@",HSFolderName,fileString]];
            model.fileName = fileString;
            [dataSource addObject:model];
        }
    }
    return dataSource;
}
