The steps to export are:1) Open the "File" menu and select the "Export" option inside;2) In the Export dialog box, select Wavefront Object (*.
OBJ is the target file, is your source program compiled after the compiler generated, it can not be directly executed, you need to connect the program to build the executable file, so you can value the line. This target file is generally composed of machine code, but there are exceptions, can be some of their own definition of pseudo-directive code, but this requires a special interpreter to interpret it, the connector is the target code and the libra
For a friend who used to do C # or Java development, the first contact with iOS development, Obj-c's function naming method may feel very unaccustomed.
In particular, open APPDELEGATE.M, the code of the eye is unexpectedly:

Background: Recently in the study of static scanning things, encountered a rule: "Equals (Object obj)" should be overridden along with the "CompareTo (T obj)" methodAnd then I want to have a deep steak. What's the difference between equals and CompareTo?First, let's look at how the Equals method under the Java.lang.String class is implemented. Public Booleanequals (Object anobject) {if( This==anobject) {//D
the stack. The object variable is somewhat different from C and is dynamically generated, similar to malloc ()-free () in C, which is stored in the heap. Object-c thus introduces dynamic runtime-based management mechanisms such as GABEGECOLLECTION,MRC,ARC, based on reference counting, to Retain,weak,copy,unsafe_unretained,strong, Assign and other keywords to manage reference counts. ARC is relatively easy to use with MRC and does not have to be manually released by the program Ape, but there ar
layout new. Such as:a buffer is created in the code, using layout new to allocate memory space at a specified position (position of displacement) on the buffer, and unlike the normal new operation, the layout new operation does not know which memory is being used, so this requires the program ape to manage its memory location. It is also important to note that when using layout new, if the buffer is not dynamically allocated, the memory cannot be freed with operations such as delete p[], and th

1. You can specify where the. o file is generated

More importantly, it is closely integrated with the C language, which is easy for those who have learned the C language. If you want to map data with a computer but do not know where to start, if you only use C language, we recommend that you learn OpenGL.
The OBJ file here does not appear during programming. It is used to compile the application file. The OBJ file here refers t
First read the introduction to OBJ in these two Chinese Blogs:

Lnk2005 errors may occur in the following situations:1
1. Define global variables repeatedly. There may be two situations:A. For some programmers who are new to programming, they sometimes think that they can use definitions to declare where they need to use global variables. In fact, this is wrong. global variables are for the entire project. The correct definition should be defined in a CPP file as follows: int g_test; in the CPP file in use, use: extern int g_test. If you still use int g_test

--------------------------------------------------------------------------------1. OBJ file Programmers write programs by writing a binary file. If we declare a variable char C, that is, the Declaration requires an 8-bit space, then we need to declare to the system that the 8-bit space is reserved. How can we do this? It is to compile a special

The polymorphism of OOD is implemented by delegation in obj-C.
5. What are the set methods and meanings of memory management autorelease, retain, copy, and assign?
1. You initialize (alloc/init) the object, and you need to release (release) it. For example:
Nsmutablearray aarray = [[nsarray alloc] init]; [aarray release];
2. You need to release retain or copy. For example:
[Aarray retain] And then [aarray rele
index, and the struct member length represents the substring's lengths. If not, the location value of the returned range is nsnotfound.
Obj-c just adds a little "special corpus" to the C language, so you can use printf () instead of NSLog (). However, we recommend using NSLog because it adds features such as timestamps, date stamps, and auto-append line breaks (' \ n ').An array member of 1.OC is any object pointer similar to the linked list struct
Relationship between OBJ, Lib, DLL, and exe
Lib corresponds to DLL. Lib is the library file of the static Link Library, and DLL is the library file of the dynamic link library.
The so-called static is to extract the required content from the link and arrange it into your EXE file. Lib is no longer needed for running your EXE later.
The so-called dynamic is that when the EXE runs, it depends on the functions provided in the DLL. Without this DLL,
1, Obj-CCodeThe extension is ". m ".
2When obj-C needs to include header files, you can use # include but more commonly use # import (provided by the GCC compiler ), the latter ensures that the header file is only contained once (L is similar to # ifdef in C ).
