Is it possible to make either a jailbreak app/tweak or regular app that could display two times on the status bar on iPhone?
Definitely, most likely using MobileSubstrate. What I can imagine as a solution is roughly:
- You hook into one of SpringBoard's initialization methods.
- You create an
UILabel
and add it to the status bar as a subview using theaddSubview:
method. - You spawn a timer (use
NSTimer
, Grand Central Dispatch or whatever suits you) to update the text of the label every minute or so. You can useNSDate
and perhapsNSLocale
(I don't have the docs in front of me right now) to find out the local time of another country.
