xcode3.2

I'm trying to use the NSDate dateFromString method but I'm getting an warning and it's crashing the app. The code looks like: NSString *pickerDate = [NSString stringWithFormat:@"%@", timeSelector.date]; NSDate *defaultDate = [NSDate dateFromString:pickerDate]; The warning is: 'NSDate' may not respond to '+dateFromString'.

I have a 3rd party .a library, which is apparently compiled for only armv6 compatibility, where both new Xcodes (3.2.6 and 4), both now require a separate armv7 slice to run on the device. The link error is: file is universal but does not contain a(n) armv7 slice for architecture armv7.
