我是游戏的新手，所以我真的只与UIScrollView合作，并且最近获得了胃灼热试图弄清楚苹果在他们现在被弃用的插入行为中的想法{ {1}}。 Apple的iOS 11插入调整行为的文档几乎完全针对func setView() {
view = UIView()
view.frame = UIScreen.main.bounds
view.backgroundColor = UIColor.white
}
func addScrollView() {
if #available(iOS 11.0, *) {
scrollView.contentInsetAdjustmentBehavior = .always
}
scrollView.translatesAutoresizingMaskIntoConstraints = false
view.addSubview(scrollView)
scrollView.leadingAnchor.constraint(equalTo: view.leadingAnchor).isActive = true
scrollView.topAnchor.constraint(equalTo: view.topAnchor).isActive = true
scrollView.widthAnchor.constraint(equalTo: view.widthAnchor).isActive = true
scrollView.heightAnchor.constraint(equalTo: view.heightAnchor).isActive = true
}
func addFirstView() {
firstView.translatesAutoresizingMaskIntoConstraints = false
scrollView.addSubview(firstView)
firstView.leadingAnchor.constraint(equalTo: scrollView.leadingAnchor).isActive = true
firstView.topAnchor.constraint(equalTo: scrollView.topAnchor).isActive = true
firstView.widthAnchor.constraint(equalTo: view.widthAnchor).isActive = true
firstView.heightAnchor.constraint(equalToConstant: 50).isActive = true
}
...
func addLastView() {
lastView.translatesAutoresizingMaskIntoConstraints = false
scrollView.addSubview(lastView)
lastView.leadingAnchor.constraint(equalTo: scrollView.leadingAnchor).isActive = true
lastView.topAnchor.constraint(equalTo: someOtherView.bottomAnchor).isActive = true
lastView.widthAnchor.constraint(equalTo: view.widthAnchor).isActive = true
lastView.heightAnchor.constraint(equalToConstant: 100).isActive = true
lastView.bottomAnchor.constraint(equalTo: scrollView.bottomAnchor).isActive = true
}
。
程序化设置：
iOS 11此设置在iOS 10中完美运行（内容插入会自动调整），但在automaticallyAdjustsScrollViewInsets中内容插入未调整 - 第一个视图与视图的顶部锚点齐平（不应该是状态栏的底部）。默认情况下，true为iOS 10。如何在<button data-url='api1.com' class='btn'>1</button>
<button data-url='api2.com' class='btn'>2</button>
$(".btn").click(function (e) {
e.preventDefault();
$.ajax({
url: $(this).data('url'),
async: false,
success: function(result) {
variable = result;
}
});
});
