One, Introduction as the C,controller in the MVC design pattern has been the most important role in project development, it is a bridge between view and data, through its management, the data methodically displayed on our view layer. Uiviewcontroller in iOS is one of the most basic classes in the Uikit framework. From the first UI view to the complex complete p

iOS development language Swift Getting started serial-classes and structsClasses and structs are a common and flexible construct that people use to build code. In order to implement various functions in classes and structs, we must define attributes and add methods in strict accordance with the syntax rules specified b

name] /*The difference between OC object methods and functions1. The function belongs to the entire file, can be called anywhere in the file; object methods belong only to objects, only objects can call object methods2. object methods can only be declared between @interface and @end , and object methods can only be implemented between @implementation and @end . The Declaration and definition of a function can be written anywhere , the function cannot be owned by a class, only belongs to a fi

IOS development: Cocoa-Explanation of classes and objects We can find the definition of class and object in/usr/include/objc. h and runtime. h: typedef struct objc_class *Class;typedef struct objc_object { Class isa;} *id; Class is a pointer of the objc_class structure type, and id (any object) is a pointer of the objc_object structure type. Its first member i

IOS development: open-source frameworks and Classes Open-source frameworks and classes used: 1: load an image using SDWebImage, UIImageView, and WebCache. 2: UIViewExt is useful for locating coordinates. You can directly obtain bottom, top, left, right. 3: CustomCatagory is a category. It contains two system versions:

change an instance variable declared in a parent class, you need to invoke the method in the parent class using the Super keyword. 3 "Compound relationship (that is, multiple classes are used in a class)1 The description method is like the ToString () method in Java, and NSLog (@ "%@") calls the description method by default.So to print an object can rewrite his description method4 "Construction methodThe method of constructing the class in OC is th

iOS development-A simple introduction to audio playback and packaging tool classesFirst, the sound of the playback of a simple introductionIn simple terms, audio can be divided into 2 types(1) Sound effectsAlso known as "short audio", usually plays in the program for 1-2 secondsEnhance the overall user experience with embellishment in the app(2) MusicFor example, the "background music" in the game, the gene

Class Extension Common methods: Define subclasses, follow protocols, use classifications, source file extensions.Source file Expansion: syntax: adding before declaring @implementation@interface Class name ()....@endCategory categoriesAdding a subclass when adding a method to an existing class is inconvenientClassification is an extension of an existing class, the classification extends only the method, the property is not extendedProtocol ProtoccolCan be used to declare a whole bunch of methodsA

1. afnetworking Among the many iOS open source projects, afnetworking can be described as the most popular library project for developers. Afnetworking is a lightweight iOS, MAC OS x network communication Class library, and now is the third largest objective-c library on the GitHub. It is based on Nsurlconnection, nsoperation and other libraries, so that many of the network communication functions to ach

Ideas The previous article only talked about unity and the integration of the iOS project, and did not talk about the handover of iOS and Unity interface, here to talk about ideas, unity export of the IOS project inside the structure is roughly the same, there is a window,window on a unityview, But there is no controller, there is no root controller, although in

I think this packaging framework is a relatively important function that can be used to do things: (1) Packaging functional modules, such as the more mature function modules packaged into a package, and then their own or other colleagues to use more convenient. (2) Packaging projects, sometimes encountered this situation, that is, a company to find two development companies to do two projects, and then ask one of their projects nested into another p
