UIActivity和AVAsset数据类型使用 [英] UIActivity and AVAsset data type usage

问题描述

根据 UIActivity Class documentation 可以将 AVAsset 对象作为数据源添加到 UIActivityTypePostToFacebook 活动。这是否意味着我们可以使用标准的 UIActivityTypePostToFacebook 活动类型发布视频？如果不是，那么可以使用 AVAsset 活动项目发送什么样的项目？

According to the UIActivity Class documentation it is possible to add AVAsset objects as a datasource to UIActivityTypePostToFacebook activity. Does it mean that we can post videos using the standard UIActivityTypePostToFacebook activity type? If not then what kind of items can I post using AVAsset activity item?

推荐答案

嗯..根据UIActivity.h

Well.. According to UIActivity.h

UIKIT_EXTERN NSString *const UIActivityTypePostToFacebook   NS_AVAILABLE_IOS(6_0); // text, images, URLs
UIKIT_EXTERN NSString *const UIActivityTypePostToTwitter    NS_AVAILABLE_IOS(6_0); // text, images, URLs
UIKIT_EXTERN NSString *const UIActivityTypePostToWeibo      NS_AVAILABLE_IOS(6_0); // text, images, URLs
UIKIT_EXTERN NSString *const UIActivityTypeMessage          NS_AVAILABLE_IOS(6_0); // text
UIKIT_EXTERN NSString *const UIActivityTypeMail             NS_AVAILABLE_IOS(6_0); // text, image, file:// URLs
UIKIT_EXTERN NSString *const UIActivityTypePrint            NS_AVAILABLE_IOS(6_0); // image, NSData, file:// URL, UIPrintPageRenderer, UIPrintFormatter, UIPrintInfo
UIKIT_EXTERN NSString *const UIActivityTypeCopyToPasteboard NS_AVAILABLE_IOS(6_0); // text, image, NSURL, UIColor, NSDictionary
UIKIT_EXTERN NSString *const UIActivityTypeAssignToContact  NS_AVAILABLE_IOS(6_0); // image
UIKIT_EXTERN NSString *const UIActivityTypeSaveToCameraRoll NS_AVAILABLE_IOS(6_0); // image, video

仅在。这意味着唯一的图像可以使用这些标准活动类型添加为AVAsset实例。

videos are mentioned only in comments for UIActivityTypeSaveToCameraRoll. This means that the only images can be added as AVAsset instances using these standard activity types.
