Swift and Objective-C hybrid programming, swiftobjective-c 1. First open Xcode6 and create a project. Here I use the default Objective-C programming language. The project name is "SwiftAndObjective ". 2. To use the Swift demo in OC, you need to create the following classes.

following results:////// The value returned isIf you create another incrementor, it will have a reference to your own independent runningtotal variable. In the following example, Incrementbysevne captures a new runningtotal variable that has no relation to the variable captured in the Incrementbyten: 7// // The value returned isIf you have a closure assigned to a property of a class instance, and the closure captures the instance by pointing to the instance or its members, you will create a st

For Swift to learn, there must be a development environment. Simply put your Xcode mac system in the right way. So let's take a quick look at what's going on here.1.1 Download XcodeXcode is Apple's programming tool, similar to the Microsoft-produced Visual Studio, which writes Java Eclipse and develops flash IDE. So-called 工欲善其事 its prerequisite, so the first thing we need to know is where to download Xcode

This is a creation in Article, where the information may have evolved or changed. This article assumes that the reader has a certain understanding of the go language and the swift language, but does not understand the mix of students. This tutorial is a simple summary based on a real-world iOS app. Let's look at the effect of the operation first: Scan Code Insta

do a lot of prep work.However, the swift language is catching fire. Some studies have shown that Swift has become the world's fastest-growing language for programming, and in addition to open source, there has been a rocket-type explosion. GitHub disclosed that Swift's popu

the current speed. The Automaticcar also provides a custom description method to output the current stop. class Automaticcar:car { var gear = 1 override var speed:double {didset {gear = Int (Speed/10.0 ) + 1 override func description ()-> String { return super.description () + } } When you set the Speed property of the Automaticcar, the Didset Viewer of the property automatically sets the Gear property to select a suitable stop for the new velocity. Specifically, the proper

the binding that must have been compatible with C in the past. Swift takes a safe programming model and adds some new features that make programming easy, colorful, and fun. Swift's self-made (that is, when the language was first created) relied on a mature and beloved coco

The most classic example of learning a new language is the output "Hello world! ”Print ("Hello world!　　") This is how swift is exported.If you have used other languages, then it seems to be very familiar. But it's a lot easier than some c.1, do not need to import some separate libraries, such as input/output or string processing function of the class library,2. Code that does not need to be written at the g

type is created, it has its own set of property values, detached from any other instance, and can also define properties for the type itself, with only one copy, regardless of the number of instances of the type. This property is the type attribute.Type properties are used to define data shared by all instances of a particular type, such as a constant that all instances can use (just like a static constant in C), or a variable that all instances can

, but then what, my purpose is, whether simple or complex, I would like to give him to understand that in the end I basically completed my goal, I know today I made my own first app (of course, is currently under review stage, is expected to appear in the Apple Store this week), until today, we touch the new language, that is the swift language, look at the

"// println ("TheBank has \ (bank.coinsinbank) Coins"//Player has now left the game. This indicates that you want to set the optional Playerone variable to nil, which means "there is no player instance." When this happens, the Playerone variable's reference to the player instance is broken. There is no other property or variable that references the player instance, so it is freed in order to empty the memory it occupies. Before this occurs, its destructor is automatically called and its coins a
