// or simply
localNotif.fireDate = now + timeInterval

try that:
试试看：
NSDate *date = [NSDate date]; // current date
NSTimeInterval delta = 60 * 1; // one minute later
if ([date respondsToSelector:@selector(dateByAddingTimeInterval:)]) {
date = [date dateByAddingTimeInterval:delta];
}
else {
date = [date addTimeInterval:delta];
}
