Use static Link Library for iOS (basic)

1. Develop a static Link Library for iOS

Open xcode to create a project and select "cocoa" under the library
Touch static library and name it "encryptlibrary ". This new static library project has no program files except "encryptlibrary_prefix.pch". Right-click the classes folder and choose "New"
File ...", Select "objective-C Class" under "cocoa touch class" and name the source file "encrypt. m ", and select generate encrypt. h header file. You can see that encrypt is generated under the classes directory. H and encrypt. M file. Enter the following content in the encrypt. h header file:

 

# Import <Foundation/Foundation. h>

@ Interface encrypt: nsobject {

}

// Encode the plaintext user name and password and return the encoded string

+ (Nsstring *) encryptusernameandpassword :( nsstring *) strusername password :( nsstring *) strpassword;

@ End

 

The content of the implementation file encrypt. m is as follows:

 

# Import "encrypt. H"

@ Implementation Encrypt

+ (Nsstring *) encryptusernameandpassword :( nsstring *) strusername password :( nsstring *) strpassword

{

Nsstring * strencrypted = [nsstring stringwithformat: @ "username: % @, password: % @", strusername, strpassword];

Return strencrypted;

}

@ End

 

Here we provide a function to encode the plaintext user name and password. So far, this static function library has been compiled. Compile this program and you will see a static library file named "libencryptlibrary. A" is generated under the products directory.

 

2. Create a static link library developed in the Project Test

Create a new "window-based application" project named "encryptlibrarytest". The following shows how to use the previously generated static library libencryptlibrary. A file in this new project.

First open the finder and translate the libencryptlibrary generated above. copy file a to encryptlibrarytest. xcodeproj directory of the same level, encrypt. copy h to encryptlibrarytest. under the classes folder in the same directory of xcodeproj, right-click frameworks> Add> existing in xcode.
Files .. add the copied libencryptlibrary. A file, and then use the functions in the static library, as shown below:

# Import <uikit/uikit. h>

# Import "encrypt. H"

 

@ Interface encryptlibrarytestappdelegate: nsobject <uiapplicationdelegate> {

Uiwindow * window;

}

 

@ Property (nonatomic, retain) iboutlet uiwindow * window;

 

@ End

Modify the implementation file as follows:

# Import "encryptlibrarytestappdelegate. H"

 

@ Implementation encryptlibrarytestappdelegate

@ Synthesize window;

 

-(Bool) Application :( uiapplication *) Application didfinishlaunchingwitexceptions :( nsdictionary *) launchoptions {

// Override point for customization after app launch.

[Self. Window addsubview: viewcontroller. View];

[Self. Window makekeyandvisible];

Nsstring * strusername = @ "caijinhui ";

Nsstring * strpassword = @ "Password ";

Nsstring * strencrypted = [encrypt encryptusernameandpassword: strusername password:
Strpassword];

Nslog (@ "% @", strencrypted );

Return yes;

}

-(Void) dealloc {

[Window release];

[Super dealloc];

}

@ End

Compile the code and pass it smoothly. The encoded string is output on the console.
