一、share extension的相关设置
这里我也就不多写这些相关设置了，因为一找可以找到一大把。
二，自定义界面以及文件类型判断

三、在相册的效果图

四、在Containing App中的一些操作
在AppDelegate中获取判断
- (BOOL)application:(UIApplication*)app openURL:(NSURL*)url options:(NSDictionary *)options
{
NSString *path = [url absoluteString];
path = [pathstringByRemovingPercentEncoding];
NSLog(@"第三方进来：%@", path);
//这里的asancloud是app的URL Schemes ，home是自己随便定义的，用于判断
if ([url.absoluteString hasPrefix:@"asancloud"]) {
//判断是否是从相册过来
if ([url.absoluteString hasSuffix:@"home"]) {//判断是否是直接跳入到添加页面
ASUploadingPathViewController *uploadVC = [[ASUploadingPathViewController alloc]init];
uploadVC.filePath=@"/";
[((UITabBarController *)self.window.rootViewController).selectedViewController pushViewController:uploadVC animated:YES];
}
}else if ([url.absoluteString hasPrefix:@"file:"]){
//判断是否从其他APP分享过来的文件
ASUploadingPathViewController *uploadVC = [[ASUploadingPathViewController alloc]init];
uploadVC.filePath=@"/";
uploadVC.fileContentPath= path;
[((UITabBarController *)self.window.rootViewController).selectedViewController pushViewController:uploadVC animated:YES];
}
return YES;
}
//处理其他app调起的情况
-(BOOL)application:(UIApplication*)application handleOpenURL:(NSURL*)url{
// 交给微信处理，如果它能处理 会回调delegate的相关方法如onResp:
return [WXApi handleOpenURL:url delegate:self];
}
五、ASUploadingPathViewController是我这里上传的页面，也是对相册过来文件的处理页面
//获取分享沙盒里的文件
NSFileManager *fileManager = [NSFileManager defaultManager];
NSURL *groupURL = [fileManager containerURLForSecurityApplicationGroupIdentifier:@"group.ASanCloud.com"];
groupURL = [groupURLURLByAppendingPathComponent:@"upload"];
NSString *dataPath = [groupURL.absoluteString substringFromIndex:15];
NSArray*array = [fileManagercontentsOfDirectoryAtPath:dataPatherror:nil];
NSLog(@"arrrrrr:%lu",(unsignedlong)array.count);
这里就可以获取到所有文件的路径地址了：NSData*data = [fileManagercontentsAtPath:fileDataPath];
这样就可以获取文件内容。
第一次写，如果有错误的地方或不妥之处请大家指正，以免误导更多人。谢谢O(∩_∩)O谢谢~~~~
