What is Mknetworkkit? Mknetworkkit is a o-c-written network framework that supports blocks, arcs, and is simple to use. Mknetworkkit set ASIHTTPRequest and afnetworking two frameworks in one. In addition to integrating the excellent features of

OBJECTIVE-C data types can be divided into: basic data types, object types, and ID types. The basic data types are: int, float, double, and char types. The object type is the type of pointer declared by a class or protocol, such as:

@property Declaration PropertiesThe way to specify attributes (attributes) For instance variables allows the compiler to generate leak-free and thread-safe ways to access instance variables.@property is the corresponding compiler directiveDeclares a

Reprint: swift3.0 and objective-c interactions need to be noted for these Chapter, Author: zeroj (Gitbub) Swift3.0 out, you can see the change is great, and cocoa, Foundation ... Interactions have also become more convenient, and Swift is writing

The preparation of C language is almost here. Finally, learn about dynamic arraysWe know that arrays of C have to specify lengths when they are defined, so how do we define dynamic arrays?The fact that the dynamic array is a space for you to use in

PrefaceAt present, Objective-c (OC) is the core language of iOS development, in the development process will also cooperate with the use of C language, C++,OC mainly responsible for the UI interface, C, C + + can be used for graphics processing.

1.C language oriented process, OC object-oriented2. First OC Program#import int main (intconstChar * argv[]) { @autoreleasepool { // Insert code here ... NSLog (@ "Hello, world! " ); } return 0 ;}1) Import introduces header

In object-oriented languages such as java/c#, access to a method can be controlled through public/private/protected to control its access rights. In OC, however, the method does not have access modifiers. So do we have a way to make it private?1. If

The classification in objective-c allows us to augment it by adding a method to a class (but we cannot add new instance variables through category), and we do not need to access the code in the class.The protocol in OBJECTIVE-C is a ubiquitous

Internal OC: Deep (copy) copy of Mutable objects and immutable objects thinking:Immutable objects: For example, the NSString object, because the NSString object is a constant string, you cannot change its contents, but you can modify the pointer

iOS memory management is a reference counting mechanism that is divided into MRC (Manual reference counting) and arc (auto reference count).The idea of managing memory with reference counts is to implement operations that generate, hold, release,

12.1 Creating categoriesCategory is a way to add a new method to an existing classExample: Get the length of a string and deposit it into the Nsdictionary dictionary Ways to not use categories: NSNumber *number; number =

Many of the veterans who have developed iOS for several years may not be very clear about the use and differences of the various structures in the. h file and the. m file. Recently studied carefully, wrote an article to write down.Generally, when

OverviewIn the process of development, many programmers do not pay attention to the management of objects or variable memory, causing the system or application to run for a period of time, it is slow, or crash. Let's talk about how memory is managed

In the concept of objective-c classes and objects. The difference and linkage between member variables and attributes has never been clear. It was not until I learned that this course on the Web Objective-c the object-oriented experience that I

Compilation warning Now the compiler is sometimes very noisy, and the warning given by the compiler is very useful to developers. The warning will not stop compilation and linking, nor cause the program to be unable to run, but many times the
