when we use OBJECTIVE-C to represent string information, we can write it in the following way .NSString *str = @ "Autumn hates snow"; str = nil;because Objective-c is a weakly typed language, the str here can be either a specific string or nil. But

Swift Language[1] Swift is a programming language that Apple publishes in WWDC2014 to compose OS X and iOS applications. When designing for Swift. OBJECTIVE-C is the programming language that Apple's operating system uses before it is imported to

This pattern allows the objects that provide related functionality the work together even when they has incompatible APIs.After home I used the Xcode IDE to sort out the swift-style code formatDiagram:ClientLet search = Searchtool

1. String and character types// in the Swift , strings are enclosed in a pair of double quotes.var str = "Hello M.sd-dj"Print (str)// The characters are enclosed in double quotation marks . with character indicates the difference between a string

*---------------------Structure-------------*/The SWIFT structure also has the concept of encapsulationThe Swift structure is a step closer to the structure in OC C, and there are ways to get closer to our classStructure definition format struct

(1) Calculating the dictionary length。(2) Determine if the dictionary is empty。(3) Querying dictionary elements。(4) Remove the dictionary elements for stitching。(5) Insert a key value pair in the dictionary。(6) The dictionary modifies a key value

The concept of generics is also present in Java, where generics can make the code more refined and an optimization for the use of data types. Now there is one requirement: write a struct, and then determine whether the integer is equal. OK, the

The basic operations of the array in Swift are as follows:(1) Calculating the length of the array.(2) Determine if the array is empty.(3) An array of new elements。(4) Array merging。(5) Inserting elements into any position。(6) Delete an element at

Remainder operatorIn most languages,% is the remainder operator. Its functionality is very simple, but it only supports redundancy between positive numbers of type int. For example 10% 3 = 1.Strictly speaking, the definition of redundancy between

We should be familiar with the concept of "instance method and type method", which is very common in objective-c. For example:1. Instance method (minus sign start)-(instancetype) init;when calling, you must instantiate an object (Alloc) before

IntroductionBefore we used int,string and other types of time, may not be carefully studied, in fact, these basic types and C or Java is not the same, not a strict "basic type", they are actually encapsulated structure.You can see the full

var someint:int = 7int is the type that represents someint, so the int can also be converted to a function type, so you can also use the function type like other typesThe function type mainly consists of three uses: (a) That's what it says. (ii) as
