iOS13 present控制器不全屏处理

升级iOS13，发现present模式modalPresentationStyle发生了改变，原来是全屏.fullScreen

现在新加了.automatic,但手机实测发现模式为.pageSheet

找到了比较方便的全局修改方法看到了,直接上代码：

//MARK: - swizzlePresent
extension UIViewController{
    //主要作用是适配ios13，将present变为全屏
      static func swizzlePresent() {

        let orginalSelector = #selector(present(_: animated: completion:))
        let swizzledSelector = #selector(swizzledPresent)

        guard let orginalMethod = class_getInstanceMethod(self, orginalSelector), let swizzledMethod = class_getInstanceMethod(self, swizzledSelector) else{return}

        let didAddMethod = class_addMethod(self,
                                           orginalSelector,
                                           method_getImplementation(swizzledMethod),
                                           method_getTypeEncoding(swizzledMethod))

        if didAddMethod {
          class_replaceMethod(self,
                              swizzledSelector,
                              method_getImplementation(orginalMethod),
                              method_getTypeEncoding(orginalMethod))
        } else {
          method_exchangeImplementations(orginalMethod, swizzledMethod)
        }

      }

      @objc
      private func swizzledPresent(_ viewControllerToPresent: UIViewController,
                                   animated flag: Bool,
                                   completion: (() -> Void)? = nil) {
        if #available(iOS 13.0, *) {
          if viewControllerToPresent.modalPresentationStyle == .automatic || viewControllerToPresent.modalPresentationStyle == .pageSheet{
            viewControllerToPresent.modalPresentationStyle = .fullScreen
          }
        }
        swizzledPresent(viewControllerToPresent, animated: flag, completion: completion)
    }
}

在AppDelegate里面调用一下就好了

UIViewController.swizzlePresent()
