在iPhone上创建全屏应用,需要遵循以下步骤:
- 使用Xcode创建一个新的应用项目。override func viewDidLoad() {
super.viewDidLoad()
if #available(iOS 13.0, *) {
let statusBar = UIView()
statusBar.backgroundColor = .white
view.addSubview(statusBar)
statusBar.translatesAutoresizingMaskIntoConstraints = false
statusBar.heightAnchor
.constraint(equalToConstant: UIApplication.shared.statusBarFrame.height)
.isActive = true
statusBar.widthAnchor.constraint(equalTo: view.widthAnchor, multiplier: 1.0).isActive = true
statusBar.topAnchor.constraint(equalTo: view.topAnchor).isActive = true
statusBar.leadingAnchor.constraint(equalTo: view.leadingAnchor).isActive = true
}
}override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
if #available(iOS 13.0, *) {
let statusBar = UIView()
statusBar.backgroundColor = .white
view.addSubview(statusBar)
statusBar.translatesAutoresizingMaskIntoConstraints = false
statusBar.heightAnchor
.constraint(equalToConstant: UIApplication.shared.statusBarFrame.height)
.isActive = true
statusBar.widthAnchor.constraint(equalTo: view.widthAnchor, multiplier: 1.0).isActive = true
statusBar.topAnchor.constraint(equalTo: view.topAnchor).isActive = true
statusBar.leadingAnchor.constraint(equalTo: view.leadingAnchor).isActive = true
}
}override func viewWillDisappear(_ animated: Bool) {
super.viewWillDisappear(animated)
if #available(iOS 13.0, *) {
let statusBar = UIView()
statusBar.backgroundColor = .white
view.addSubview(statusBar)
statusBar.translatesAutoresizingMaskIntoConstraints = false
statusBar.heightAnchor
.constraint(equalToConstant: UIApplication.shared.statusBarFrame.height)
.isActive = true
statusBar.widthAnchor.constraint(equalTo: view.widthAnchor, multiplier: 1.0).isActive = true
statusBar.topAnchor.constraint(equalTo: view.topAnchor).isActive = true
statusBar.leadingAnchor.constraint(equalTo: view.leadingAnchor).isActive = true
}
}
- 在项目中,选择一个合适的模板,例如“Single View App”。
- 在项目的主视图控制器中,设置视图的边缘约束,使其与屏幕边缘对齐。
- 在项目的Info.plist文件中,添加一个名为“UIStatusBarStyle”的键,并将其值设置为“UIStatusBarStyleLightContent”。
- 在主视图控制器的viewDidLoad方法中,设置状态栏的样式为白色,例如:
- 在主视图控制器的viewWillAppear方法中,设置状态栏的样式为白色,例如:
- 在主视图控制器的viewWillDisappear方法中,还原状态栏的样式为默认样式,例如:
- 运行应用程序,检查是否已成功创建全屏应用。
通过以上步骤,您可以在iPhone上创建一个全屏应用。
