uibutton - Creating button panel in iOS -

-

we plan create wechat -like ui in our app, , we'd know how create such button panel.

please @ screenshots below:

screenshot 1

screenshot 2

screenshot 3

so behaviour is:

screen shot 1 - chat ui, , there bar @ bottom containing text field.

screen shot 2 - clicking on text field brings virtual keyboard.

screen shot 3 - note there + button in bar, , clicking button dismisses virtual keyboard, revealing button panel contains buttons below bar, , these buttons provides features uploading images, shooting photos, etc.

how implement such ui, more specifically, how implement button panel? thanks!
