Flappybird mini-game with SwiftWith Apple's deep-dive approach to swift, Swift's quick fire and Swift's streamlined syntax and powerful features, it's also necessary to learn about Swift for developers who use OBJECT-C to develop iOS. This blog skips Swift's dry grammar and starts using swift directly from a small game project, summarizing the gains as follows: F

Structs and enumerations can also define methods in swift, whereas in Objective-c, a class is the only type that can define a method.　　Instance methodAn instance method is a method that belongs to a particular class, struct, or instance of an enumeration type that provides access to and modify instance properties, and the syntax of the instance method is exactly the same as the function. An instance method can implicitly access all other instance meth

Conversion Between Swift numeric types, Swift numeric type conversionConversion Between Swift numeric types Swift is a secure language that requires strict type checks and cannot be converted between different types.1. Integer ConversionIn other languages such as C and Objective-C, there are two conversion methods betw

Unlike other programming languages, Swift does not require you to create separate interfaces and implementation files for your custom classes and structs. All you have to do is define a class or struct in a single file, and the system will automatically generate external interfaces for other code.　　Note: Typically an instance of a class is called an object. However, in swift, classes and structs are more cl

Yesterday tried to write code after the feeling write than just a lot, so today wrote a bit of things, mainly the properties of the class, as well as inheritance and xib some knowledge, but also encountered a lot of trouble, but fortunately have been solved, here simply write the code today, there is nothing wrong place, or hope to come.First look at the first simple page: Click the second button, the view changes color below, click the first button, modal a pageThe first is some of the properti

Instantiate an object based on the class name, for example, to 一个类名的 create a Viewcontroller instance from a string.Let Controllername="Spainappproto. "+xibname // Xibname-shaped like Xxviewcontrollervar classtype:anyobject.type= asBut when you instantiate according to Uiviewcontroller.self, you need to convert a little bit. var x:string = m.debugdescription // m is uiviewcontroller.self x = X.stringbyreplacingoccurrencesofstring ("Optional (" "") = X.stringbyreplacingoccurrences

Shake a shake function presumably everyone has used, the new Year's time to rob red envelopes did not less shake it, then the swift language how to achieve such cool features. Shake belongs to an iOS built-in recognizable action, in the viewcontroller that you need to implement the Shake function, add the following code to the Viewdidload method:Uiapplication.sharedapplication (). Applicationsupportsshaketoedit = True self.becomefirstresponder

Using the switch switch statement in Swift does not need to add a break to the match when it is matched, and in swift it automatically jumps out where the match succeeds. Will not be executed in the following directionExample"Let vegetable =" red pepper "Switch Vegetable {Case "Celery":Let vegetablecomment = "Add some raisins and make ants on a log."Case "cucumber", "watercress":Let vegetablecomment = "so w

Comments Use annotations to inject executable text into your own code as your own notes or hints. Comments are ignored when the Swift compiler runs. Swift's comments are very similar to the C language, with Single-line comments beginning with two backslashes: This is a line of comments Multiline comment begins with///ends with/*: See more highlights of this column: http://www.bianceng.cnhttp://www.bianceng.cn/Programming/extra/ Unlike multili
