Hello, I'm using UITableViewCellStyleValue1 in my table and setting some text for both the textLabel and detailTextLabel. In one cell the detail text label is a long URL, which overlaps with the textLabel (normally "URL" and then shortened to "U."), which sucks.

As a follow up to this previous question, I have a Core Data-based iPhone app that gets its underlying SQLite database file pre-loaded by a small utility, written in Cocoa, which I also wrote. Basically, I'm taking data from text files and building my data off-line, so the app is as fast as possible when it runs (i.e. no data parsing on ...

So even though they aren't in the app, I want to be able to pop up an alert from the app, reminding them to do something. Is that allowed with the iPhone sdk? Maybe it isn't even a big deal at all, but for some reason I was thinki...
