Swift3.0 与 Android对应的语法或方法（持续更新）

习惯了android开发的我转swift，当然是找相同点,qq 549890025  可以共同研究

这里有篇概括性文章：

android: toast提示

toast.makeText(this,"hahaha",1).show();

swift： toast提示

亲测可用，代码是copy的，论英文的重要性。要引入第三方frameword Toast-Swift,使用cocopods的话 pod 'Toast-Swift','~> 2.0.0' 然后在终端terminal cd到项目根目录（里面包涵profile文件）输入

pod install 不填版本默认最新，下载下来之后,command+B build项目一下，然后就可以引入 import Toast_Swift。 

// basic usage
self.view.makeToast("This is a piece of toast")

// toast with a specific duration and position
self.view.makeToast("This is a piece of toast", duration: 3.0, position: .Top)

// toast with all possible options
self.view.makeToast("This is a piece of toast", duration: 2.0, position: CGPoint(x: 110.0, y: 110.0), title: "Toast Title", image: UIImage(named: "toast.png"), style:nil) { (didTap: Bool) -> Void in
    if didTap {
        print("completion from tap")
    } else {
        print("completion without tap")
    }
}

// display toast with an activity spinner
self.view.makeToastActivity(.Center)

// display any view as toast
self.view.showToast(myView)


// create a new style
let style = ToastStyle()

// this is just one of many style options
style.messageColor = UIColor.blueColor()

// present the toast with the new style
self.view.makeToast("This is a piece of toast", duration: 3.0, position: .Bottom, style: style)

// or perhaps you want to use this style for all toasts going forward?
// just set the shared style and there's no need to provide the style again
ToastManager.shared.style = style

// toggle "tap to dismiss" functionality
ToastManager.shared.tapToDismissEnabled = true

// toggle queueing behavior
ToastManager.shared.queueEnabled = true

 

swift: UIAlertController提示

let alertController = UIAlertController(title: "通知", message: "确定还是取消", preferredStyle: UIAlertControllerStyle.Alert) // 这里因为控件都不存在改变的可能，所以一律使用let类型
 
   let alertView1 = UIAlertAction(title: "确定", style: UIAlertActionStyle.Default) { (UIAlertAction) -> Void in
 
       print("确定按钮点击事件")
 
   }
 
   let alertView2 = UIAlertAction(title: "取消", style: UIAlertActionStyle.Default) { (UIAlertAction) -> Void in
 
       print("取消按钮点击事件")
 
   }
 
   let alertView3 = UIAlertAction(title: "下次吧", style: UIAlertActionStyle.Default) { (UIAlertAction) -> Void in
 
       print("下次吧按钮点击事件")
 
   }
   alertController.addAction(alertView1)
 
   alertController.addAction(alertView2)
 
   alertController.addAction(alertView3) // 当添加的UIAlertAction超过两个的时候，会自动变成纵向分布
 
   self.presentViewController(alertController, animated: true, completion: nil)

 

 

 

android:存储字段

public int getInt(String key) {
SharedPreferences sharedata = context.getSharedPreferences("data", 0);
return sharedata.getInt(key, 1);
}

 

swift:存储字段

UserDefaults.standard.set("content", forkey:"keyword")
UserDefaults.standard.object(forkey:"keyword")
