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：
<key>CFBundleDocumentTypes</key>
<array>
<dict>

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：
第二步：通过- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary*)options {}函数.可以获取到文件路径,然后继续相关操作
第三步：读取文件
- (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;
}
