启动页放12张图每次启动随机显示其中的一张的代码

12张图片命名合理一点，NSInteger minute = [[[NSCalendar currentCalendar] components:NSMinuteCalendarUnit fromDate:[NSDate date]] minute];

   

    splashView = [[UIImageView alloc] initWithFrame:self.window.frame];

    splashView.autoresizingMask = (UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight);

    splashView.image = [UIImage imageNamed:[NSString stringWithFormat:@"splash%d.png", minute % SPLASH_IMG_COUNT]];

图片命名有规律：12张图片比如说，image1.png,image2.png,^
