// 1 滚动的范围(scrollView能滚多远)没有设置这个属性,就不能滚动 scrollView.contentSize = CGSizeMake(imageView.image.size.width, imageView.image.size.height);
// 2 代码设置这个属性默认看不到效果,拖动松手之后才能看到效果 // scrollView.contentInset = UIEdgeInsetsMake(20, 20, 40, 80);
// 3 隐藏滚动条 scrollView.showsHorizontalScrollIndicator = NO; scrollView.showsVerticalScrollIndicator = NO;
// 4 弹簧效果 scrollView.bounces = NO;
