Action based on time of day?

My application has two sets of icons, one for day and one for night. What kind of if-then statement can I use to tell my app that if the time is later than 8PM-7AM.. do this action and if it is between 7AM-8PM.. do a different action?

Thanks

make a day and night enum or bool ivar

When your app is launching , you can get the current time .And then you can calc whether it is day or night , and then set the enum.

Then if it is day now, you should calc the timeInterval from now to 8PM named timeInterval1, then make a NSTimer to invocation your method to change the enum to night. The delay time is timeInterval1.

- (void)yourmethod
{
    if(enum == day)
    {

    }
    else
    {
    }
}
