ios开发 静态库制作

IOS程序是由Objective-c语言构成，而是Objective-c语言中每一个类又分成 .h .m 文件。静态库可以将这些程序的类封装成一个.a文件，第三方应用程序只需要拿到这个.a文件和代码对应的.h文件即可使用静态库中封装的方法。总的来说IOS静态库适合去制作第三方提供的SDK，废话不多说了我们直接进正题。

制作静态库

代码如下

#import <Foundation/Foundation.h>

@interface BookModelLib : NSObject
{
    NSString* _iconUrl;
    NSString* _bookName;
    NSString* _publisher;
    NSString* _price;
    NSString* _autherName;
    NSString* _pubdate;
    NSString* _translator;
    NSString* _introUrl;
    NSInteger _numRatings;
}
@property(retain, nonatomic)NSString* iconUrl;
@property(retain, nonatomic)NSString* pubdate;
@property(retain, nonatomic)NSString* introUrl;
@property(retain, nonatomic)NSString* autherName;
@property(retain, nonatomic)NSString* translator;;
@property(retain, nonatomic)NSString* bookName;
@property(retain, nonatomic)NSString* publisher;
@property(retain, nonatomic)NSString* price;
@property(assign, nonatomic)NSInteger numRatings;

-(void)showInfo;


@end

#import "BookModelLib.h"

@implementation BookModelLib

-(void)showInfo
{
    NSLog(@"_bookName:%@",_bookName);
    NSLog(@"_publisher:%@",_publisher);
    NSLog(@"_price:%@",_price);
}

@end

cmd＋B编译，编译的时候选择两种环境编译

合并.a文件 

lipo -create libBookModelLib_os.a libBookModelLib_lib.a -output libBookModelLib.a

使用静态库

使用静态库就比较简单了，将.h头文件和.a文件拖入项目

#import "ViewController.h"
#import "BookModelLib.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    
    BookModelLib *bModel=[[BookModelLib alloc]init];
    bModel.bookName=@"fewfwefe";
    bModel.iconUrl=@"http://fjoewjf";
    bModel.publisher=@"fewfewfewew";
    bModel.price=@"few50";
    [bModel showInfo];
    
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

@end

呵呵，ok，这样就可以直接使用静态库了，超级简单有木有。。。。
