#runLoop保活UIScrollowView

####You can change color by the way "scrollowview.foregroundColor = [UIColor whiteColor];"

####Or you can change color by the way "scrollowview.backgroundColor = [UIColor lightGrayColor] ;“

####And if you want to change "Timer's" time ,you can "scrollowview.timeInterval".

####In the end you can add target by " [scrollowview addTarget:self action:@selector(onclick)];"

#Thank you !
