Make Popups With Cocoa Touch

I'm trying to make a popup like in "Ca开发者_运维百科mera+" or "Tweetbot" (like this one : Tweetbot or this one Camera+). How can I do this ?

That component is generally called a Popover or a Callout. Apple provides you with an Implementation on the iPad (UIPopover) but not on the iPhone.

There are a few Libraries which attempts to solve this and creates similar popovers like the ones you've shown. With a bit of customisation you can get it to look like this ones you've linked. Below is a list of the ones i've found so far:

• WEPopover
• CMPopTipView
• PopupView

There's similar question here: iPhone popup menu like iPad popover?.

There is a solution. It's called WEPopover and you can download it from github.

For ipad use the popover control:
