Parsing Objective-C Program Design

Objective-C ProgrammingIs the content to be introduced in this article, mainly introducesObjective-C Programming. Let's just look at the details.

 
 

  
  
#import <Foundation/Foundation.h> 
  
  
int main(int argc,const char *argv[])  
  
  
{  
  
  
    NSAutoreleasePool *pool = [[NSAutorelease Pool alloc] init];  
  
  
    NSLog(@"Programmint is fun!");  
  
  
    [pool drain];  
  
  
    return 0;  
  
  
} 
 
 

Output: Programming is fun!

1. Compile and run the program

You can use Xcode or the CNU Objective-C compiler to compile and run the program in the Terminal window.

1. Xcode

Xcode is located in the application sub-folder in the Develope folder,

2. Terminal

Developers who are used to using UNIX shells and command lines.

II,

1. In the OC language, note "//" and ""

2. # import: import or include the file information into the program.

3. Use [pool drain] to release the allocated memory pool and objects associated with the program ).

4. NSLog history is a function in the OC library, which only displays or records the parameter or parameter list ). Displays simple phrases, variable values, and variable results.
