runtime racing

Versions and platformsThe runtime system, for Objective-c, is like its operating system, or running support platform, which allows the OBJECTIVE-C code to run in accordance with established language features. In contrast to C + +, objective-c as much as possible to postpone some actions to run, that is, to do things as dynamically as possible. Therefore, it requires not only a compiler, but also a runtime e

recently participated in three interviews have been asked to the runtime, do not know the interviewer themselves understand, anyway, like to ask, seems to want to put me bluffing, to show their understanding of OC bottom knowledge is very good. (I now start to look at the interview questions, found that they all like to ask the question of interview questions, I figured out, are test-oriented education to provoke the curse, probably they have no actua

Runtime (IOS)First, what is the runtime (runtime)? Runtime is the pure C-language development library provided by Apple (Runtime is a very good, often used in the development of the underlying technology) Second, the role of the run time? To get all th

first, let's comb the bottom concept of the runtime, and if you want to see how it can be turned to the bottom. Brief Introduction Runtime is also called runtime, is a set of low-level C language API, which is one of the core of IOS internal, we usually write the OC code, the bottom is based on it to achieve. Like what: [Receiver message]; The underlying

Understand the runtime address and link address from the two-statement assembly, and the Assembly link address First, let's look at two lines of assembly code: 1: adr r0, _start 2: ldr r1, =_start Load the address value of a label. What is the difference between adr and ldr? Note that the ldr here is not a command ldr, but a pseudo command ldr. If you want to differentiate them, please refer to my blog "Summary of adr adrl ldr mov". To dis

There are two ways to specify the location of an assembly: Use the element. Use the element. You can also use the . NET Framework Configuration Tool (Mscorcfg.msc) to specify an assembly location or for the common language runtime to specify the location to probe the assembly. Using The element is available only in the Computer configuration file or in the publisher policy file that also redirects the assembly version. When the

ObjectiveIn the previous article we tasted the black magic of runtime, we can get the name of the member variable in the program compile stage, attribute and dynamic to the object increment attribute, and so on, in the next we further understand OC's message sending mechanism. If you have not had contact with the runtime before the classmate suggested to look at: the previous "

Compiling a program encountered several errors and found it to be a problem with the library settings during runtime. I found this was a good one on the Internet. Original article: http://dearymz.blog.163.com/blog/static/205657420096675044722/ VC project properties → configuration properties → C/C ++ → code generation → runtime libraries can adopt the following methods: multi-thread (/mt) and multi-thread d

OC is a fully dynamic language, and everything in OC is implemented based on runtime! Understand runtime from the following three aspects! 1. Traditional process-oriented language development, such as C language. Implementing the C language compiler is simple, as long as you implement an lalr according to the syntax rulesSyntax analyzerAs you can, compiler optimization is a very difficult topic, which is no

Recently, libraries on different platforms need to be compiled. Therefore, more attention is paid to the underlying layer than only C ++ programs were previously developed. Let's take a look at the explanation of the term runtime system. References: Http://en.wikipedia.org/wiki/Runtime_system The runtime system is sometimes called "RunTime", but the literal

Objective-c language is a dynamic language that puts a lot of static language in the process of compiling and linking things to the runtime. At the same time OC is also a simple language, a large part of the content of C, just add the language level of the keyword and grammar, really make OC powerful is its running, it is very small but very powerful, wherein the core is the message distribution.

Often have small partners privately in Q asked some things about the runtime , asked if I have runtime related blog, before really did not serious summed up. Before just parsing the third-party framework source code, talked about some usage, that is, these third-party framework used in the runtime. such as attribute associations, dynamic acquisition of properties

Msvcrt. dll (Name: Microsoft C Runtime Library) provides C language Library functions such as printf, malloc, strcpy, and uses C/C ++ (Vc) the compile program provides initialization (such as obtaining command line parameters) and exit functions. C Runtime Library history, API, STL, MFC, and ATL relationships When I first got started with Windows development, I checked a lot of information for quick start

A large number of objective-c developers have emerged in the past few years. Some are transferred from a dynamic language, such as Ruby or Python, some of which are transferred from a strongly typed language, such as Java or C #, and, of course, with Objective-c as the introductory language. This means that a large part of the developers are not using objective-c for too long. When you touch a new language, you pay more attention to the basics, such as grammar and features.But there are usually
