1. 一般加一个-webkit-overflow-scrolling: touch；就行了

// 页面最外层盒子
	.getPicking {
		width: 100%;
		-webkit-overflow-scrolling: touch；
}

2.再不行就加

       -webkit-overflow-scrolling: touch;
        overflow-scrolling: touch;
        overflow-y: scroll;

// 页面最外层盒子
	.getPicking {
		width: 100%;
		-webkit-overflow-scrolling: touch;
		overflow-scrolling: touch;
		overflow-y: scroll;
}
