Swift4.2 适配记录

大部分都可以在Xcode中find然后replace

AVAudioSession.sharedInstance().setCategory(AVAudioSession.Category.record)

替换为

if #available(iOS 10.0, *) {
                try AVAudioSession.sharedInstance().setCategory(AVAudioSession.Category.playback, mode: AVAudioSession.Mode.default, options: [.allowAirPlay, .allowBluetooth])
            } else {
                // Fallback on earlier versions
            }

 
public override var hashValue: Int {
        return 1
    }

替换为

public override var hash: Int {
        return 1
    }

UICollectionViewScrollDirection

替换为

UICollectionViewScroll.Direction

UIEdgeInsetsMake(10,10,10,10)

替换为

UIEdgeInsets(top:10, left:10, bottom:10, right:10)

考虑到这样子替换会难受死：可以使用extension去做

extension UIEdgeInsets {
    convenience init(_ top: CGFloat, _ left: CGFloat, _ bottom: CGFloat, _ right: CGFloat) {
        self.init(top: top, left: left, bottom: bottom, right: right)
    }
}

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool

替换为：

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool

override func didMove(toParentViewController parent: UIViewController?) {
   super.didMove(toParentViewController: parent) 
   ...
}

替换为

override func didMove(toParent parent: UIViewController?) {
   super.didMove(toParent: parent) 
   ...
}

Runloop.Mode.common

UIImagePickerControllerOriginalImage
UIImagePickerControllerReferenceURL

替换为

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {...}
UIImagePickerController.InfoKey.originalImage
UIImagePickerController.InfoKey.referenceURL

UITableViewAutomaticDimension

替换为

UITableView.automaticDimension

MJRefresh 适配

arrowImage = [[UIImage imageWithContentsOfFile:[[self mj_refreshBundle] pathForResource:@"arrow@2x" ofType:@"png"]] imageWithRenderingMode:AlwaysTemplate];
