1、UIScrollView
增加了属性allowsKeyboardScrolling表示是否根据连接的物理键盘的方向键而滚动。
import UIKitclass ViewController: UIViewController { lazy var scrollView: UIScrollView = { let scrollView = UIScrollView(frame: CGRect(x: 0, y: 0, width: UIScreen.main.bounds.width, height: UIScreen.main.bounds.width)) let imageView = UIImageView(image: UIImage(named: "img")) scrollView.addSubview(imageView) scrollView.contentSize = imageView.bounds.size // iOS17新增，默认为true scrollView.isScrollEnabled = false return scrollView }() override func viewDidLoad() { super.viewDidLoad() view.addSubview(scrollView) }}
2、applicationIconBadgeNumber
UIApplication 的applicationIconBadgeNumber属性被废弃，建议使用UNUserNotificationCenter.current().setBadgeCount()方法。
import UIKitimport UserNotificationsclass ViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() } override func touchesBegan(_ touches: Set, with event: UIEvent?) { // iOS17之后设置角标，需要先授权 // UNUserNotificationCenter.current().setBadgeCount(10) UNUserNotificationCenter.current().setBadgeCount(10) { error in if let error { print(error) } } }}
3、UIDocumentViewController
新增视图控制器，用于显示与管理本地或者云端文档。
import UIKitclass ViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() } override func touchesBegan(_ touches: Set, with event: UIEvent?) { let documentViewController = UIDocumentViewController() documentViewController.openDocument { _ in print("打开文档") } present(documentViewController, animated: true) }}
4、UIHoverStyle
UIView 增加了一个hoverStyle属性，可以设置鼠标移动到 UIView 之上的效果。
import UIKitclass ViewController: UIViewController { lazy var redView: UIView = { let view = UIView(frame: CGRect(x: 200, y: 200, width: 200, height: 200)) view.backgroundColor = .red // iOS17新增UIHoverStyle，可以设置Hover的效果与形状（UIShape） let hoverStyle = UIHoverStyle(effect: .lift, shape: .capsule) // iOS17新增，鼠标移动到UIView之上的效果 view.hoverStyle = hoverStyle return view }() override func viewDidLoad() { super.viewDidLoad() view.addSubview(redView) }}
5、编译报错cfstring constant not pointer aligned
解决办法：Build Settings -> Other Linker Flags 加入-ld64
6、编译报错Sandbox：rsync.sanba deny(1) file-write-create xxx
使用 Xcode15 新建项目后，pod 引入部分第三方会报上面的错误解决办法：Build Settings 搜索 sandbox，把 Build Options 中的 User Script Sandboxing改为 NO7、编译报错UIGraphicsBeginImageContextWithOptions崩溃
参考链接：UIGraphicsBeginImageContext Deprecated
YYText使用时会崩溃在UIGraphicsBeginImageContextWithOptions
