使用WhatsApp和FB的UIActivityViewController或UIDocumentInteractionController [英] UIActivityViewController or UIDocumentInteractionController with WhatsApp and FB

问题描述

我需要将Facebook和WhatsApp作为我图像的共享选项。我已经实现了UIActivityViewController，我可以通过Facebook和 UIDocumentInteractionController 分享，我可以通过WhatsApp分享。我不知道如何合并这些东西。

I need to have Facebook and WhatsApp as sharing options for my image. I've already implemented UIActivityViewController, where i can share via Facebook and UIDocumentInteractionController where i can share via WhatsApp. I don't know how to merge these things.

UIActivityViewController：

UIActivityViewController *activityViewContoller = [[UIActivityViewController alloc] 
       initWithActivityItems:@[@"Test", image] applicationActivities:nil];
[self presentViewController:activityViewContoller animated:YES completion:nil];

UIDocumentInteractionController：

NSString *savePath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/whatsAppTmp.wai"];
    [UIImageJPEGRepresentation(image, 1.0) writeToFile:savePath atomically:YES];

    _documentInteractionController = [UIDocumentInteractionController 
                 interactionControllerWithURL:[NSURL fileURLWithPath:savePath]];
    _documentInteractionController.UTI = @"net.whatsapp.image";
    _documentInteractionController.delegate = self;
    [_documentInteractionController presentOpenInMenuFromRect:CGRectZero 
                                    inView:self.view animated:YES];

我希望将它们都放在一个popover中，但是我不知道如何实现它。请问有什么提示吗？

I want to have both of them in one popover, however I have no idea how to achieve it. Any tip please?

我已经查看了 StackOverFlow问题1 ，但它根本没有帮助我。我的文件是.wai（对于WhatsApp）所以当我尝试通过FB文件发送它无法打开。它还显示所有选项，而我只想要2（FB + WhatsApp）可见。关注 StackOverFlow问题2 只能显示FB（工作一个，因为我设置正常图像）但不能添加WhatsApp（没有.wai文件，我不知道如何处理UTI）。有没有办法解决这个问题？

I've checked out StackOverFlow question 1, but it doesn't help me at all. My file is .wai (for WhatsApp) so when i try to send it via FB file is unable to open. Also it shows all options, while i want only 2(FB+WhatsApp) to be visible. Following the StackOverFlow question 2 I can show only FB (working one, because i set normal image) but can't add WhatsApp (no .wai file, i don't know what to do with UTI). Is there any way to solve this issue?

推荐答案

要更改文件类型：

- (void)share {
    NSString *path = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/tmptmpimg.jpg"];
    [UIImageJPEGRepresentation(_img, 1.0) writeToFile:path atomically:YES];

    _documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:path]];
    _documentInteractionController.delegate = self;
    [_documentInteractionController presentOptionsMenuFromRect:CGRectZero inView:self.view animated:YES];
}

- (void)documentInteractionController:(UIDocumentInteractionController *)controller willBeginSendingToApplication:(NSString *)application {
    if ([self isWhatsApplication:application]) {
        NSString *savePath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/tmptmpimg.wai"];
        [UIImageJPEGRepresentation(_img, 1.0) writeToFile:savePath atomically:YES];
        controller.URL = [NSURL fileURLWithPath:savePath];
        controller.UTI = @"net.whatsapp.image";
    }
}

- (BOOL)isWhatsApplication:(NSString *)application {
    if ([application rangeOfString:@"whats"].location == NSNotFound) { // unfortunately, no other way...
         return NO;
    } else {
         return YES;
    }
}

这样我们就可以使用所有选项 - Facebook，Twitter和自定义WhatsApp。

This way we can use all options- Facebook, Twitter and custom WhatsApp.

仅显示所选选项的问题仍然没有解决，但它是次要问题。

The problem with showing only selected options is still not solved, but it's the minor one.
