Swift 中交换 AppDelegate 的 application(_:supportedInterfaceOrientationsForWindow:) 方法
在 Swift 中,可以使用以下方法来交换 AppDelegate 中的 application(_:supportedInterfaceOrientationsForWindow:) 方法。
首先,创建一个新的类 MethodSwizzleHelper,其中包含一个用于交换方法的静态函数 exchangeMethods:
class MethodSwizzleHelper {
static func exchangeMethods() {
let originalSelector = #selector(AppDelegate.application(_:supportedInterfaceOrientationsFor:))
let swizzledSelector = #selector(AppDelegate.swizzled_application(_:supportedInterfaceOrientationsFor:))
let originalMethod = class_getInstanceMethod(AppDelegate.self, originalSelector)
let swizzledMethod = class_getInstanceMethod(AppDelegate.self, swizzledSelector)
method_exchangeImplementations(originalMethod!, swizzledMethod!)
}
}
接下来,在 AppDelegate 中的 application(_:didFinishLaunchingWithOptions:) 方法中调用 MethodSwizzleHelper.exchangeMethods(),以交换方法:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
MethodSwizzleHelper.exchangeMethods()
// 其他代码
return true
}
最后,实现交换后的方法 swizzled_application(_:supportedInterfaceOrientationsFor:),并在其中添加自定义的逻辑:
extension AppDelegate {
@objc func swizzled_application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
// 添加自定义逻辑
// ...
// 调用原始方法
return self.swizzled_application(application, supportedInterfaceOrientationsFor: window)
}
}
通过以上步骤,你可以成功交换 AppDelegate 中的 application(_:supportedInterfaceOrientationsForWindow:) 方法,并在其中添加自定义的逻辑。
