Share Extension - 自定義界面，上傳相冊文件

一、share extension的相關(guān)設(shè)置

這里我也就不多寫這些相關(guān)設(shè)置了，因為一找可以找到一大把。

二，自定義界面以及文件類型判斷

三、在相冊的效果圖

四、在Containing App中的一些操作

在AppDelegate中獲取判斷

- (BOOL)application:(UIApplication*)app openURL:(NSURL*)url options:(NSDictionary *)options

{

    NSString *path = [url absoluteString];

    path = [pathstringByRemovingPercentEncoding];

    NSLog(@"第三方進(jìn)來：%@", path);

//這里的asancloud是app的URL Schemes  ，home是自己隨便定義的，用于判斷

    if ([url.absoluteString hasPrefix:@"asancloud"]) {

//判斷是否是從相冊過來

        if ([url.absoluteString hasSuffix:@"home"]) {//判斷是否是直接跳入到添加頁面

            ASUploadingPathViewController *uploadVC = [[ASUploadingPathViewController alloc]init];

            uploadVC.filePath=@"/";

            [((UITabBarController *)self.window.rootViewController).selectedViewController pushViewController:uploadVC animated:YES];

            }

    }else if ([url.absoluteString hasPrefix:@"file:"]){

//判斷是否從其他APP分享過來的文件

        ASUploadingPathViewController *uploadVC = [[ASUploadingPathViewController alloc]init];

        uploadVC.filePath=@"/";

        uploadVC.fileContentPath= path;

        [((UITabBarController *)self.window.rootViewController).selectedViewController pushViewController:uploadVC animated:YES];

    }

    return YES;

}

 //處理其他app調(diào)起的情況

-(BOOL)application:(UIApplication*)application handleOpenURL:(NSURL*)url{

    // 交給微信處理，如果它能處理 會回調(diào)delegate的相關(guān)方法如onResp:

    return [WXApi handleOpenURL:url delegate:self];

}

五、ASUploadingPathViewController是我這里上傳的頁面，也是對相冊過來文件的處理頁面

//獲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);

這里就可以獲取到所有文件的路徑地址了：NSData*data = [fileManagercontentsAtPath:fileDataPath];

這樣就可以獲取文件內(nèi)容。

第一次寫，如果有錯誤的地方或不妥之處請大家指正，以免誤導(dǎo)更多人。謝謝O(∩_∩)O謝謝~~~~
