UIActivityController在设备和模拟器上的行为不同 [英] UIActivityController behaviour different on device and simulator

问题描述

我在我的应用中添加了一个activityViewController，如下图所示，传入图像

I add an activityViewController to my app like below, passing in an image

UIActivityViewController *avc = [[UIActivityViewController alloc]initWithActivityItems:[NSArray arrayWithObjects:img,nil] applicationActivities:[NSArray arrayWithObjects:nil]];
        [self presentModalViewController:avc animated:YES];
        [avc release];

在模拟器上（所有未配置的推特，facebook和微博账号）：

选项邮件，推特，脸书，微博，分配给联系人，保存到相机胶卷，打印和复印默认显示。

options mail, twitter, facebook, weibo, assign to contact, save to camera roll, print, and copy appear by default.

，但在设备上：

在我的应用中：twitter，facebook和weibo仅显示帐户是否已配置。

in my app: twitter, facebook and weibo only show if the accounts are configured.

在safari中：无论帐户是否配置，都可以使用Twitter，facebook和微博选项。

in safari: twitter, facebook and weibo options are available irregardless of whether the accounts are configured.

I我希望我的应用程序中的行为与safari相同。我错过了一个特定的步骤吗？

I am expecting the same behaviour in my app as safari. am I missing a particular step?

推荐答案

好的我已经找到了问题。

Okay I have figured the problem.

UIActivityViewController中显示的选项完全取决于要共享的项目类型。例如，如果有视频，则不会显示Facebook或Twitter选项。但如果它是一个图像和标题，它肯定会显示相关的选项。

The options shown in the UIActivityViewController totally depends on the type of items that are to be shared. For example, if there is a video, it will not show Facebook or twitter option. But if it's an image and title, it definitely will show the relevant options.

以下内容将显示邮件，推特，Facebook，assignToContact，保存到相机胶卷，打印，复印等应用程序

The following will show up apps like mail, twitter, Facebook, assignToContact, save to camera roll, print, copy, etc

// Create the content
NSString *message = @"The Upcoming App Scribble Talk";
UIImage *imageToShare = [UIImage imageNamed:@"createbtn.png"];

NSArray *objectsToShare = [NSArray arrayWithObjects:message, image, nil];

但是，以下内容仅提供相机胶卷，邮件或复印件。

However, the following shall bring up only camera roll, mail or copy.

NSString *message = @"The Upcoming App Scribble Talk";
NSString *videoToShare = @"myFirsScribble.mov";
NSURL *videoPath = [NSURL fileURLWithPath:videoToShare];

NSArray *objectsToShare = [NSArray arrayWithObjects:message, videoPath, nil];
