问题 My app gives the shuttle schedule for my school's shuttle bus, and I am updating the app to check what day of the year it is, and if it is summer to display the summer schedule, which is different from the normal schedule. That part's easy. What I'm wondering is if I can choose to use a different launch image based on a programmatic condition, such as: if ( today isBetweenDate: juneFirst andDate: augustThirtyFirst ) { launchImage == summerLaunchImage.png } 回答1: The initial launch screen
