请教 iOS 开发关于 AirDrop 下方显示的“在 XX 中打开”的问题

Answer 1

This thing is called UTI, Uniform Type Identifiers

You can read Apple’s documentation here

https://developer.apple.com/library/ios/documentation/FileManagement/Conceptual/understanding_utis/understand_utis_declare/understand_utis_declare.html

1. First, register the file types you can open in info.plist

1. Then if someone chooses to use your App to open this file, this function will be called. You can implement it:

• (BOOL)application:(UIApplication )application openURL:(NSURL )url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation

You can also open a controller here

That’s almost it, you should be able to pull it out once you find the direction. . If you want a demo. . I can masturbate too. . (Allow me to fill in the gaps later)
