1.通过cocopods安装Aspects

target 'AspectDemo' do
    pod "Aspects"
    end

2.包含头文件<Aspects/Aspects.h>和实现方法

#import "ViewController.h"
    #import "AspectTest.h"
    #import <Aspects/Aspects.h>
    
    @interface ViewController ()
    @property (nonatomic,strong) id<AspectToken> test0Token;
    @property (nonatomic,strong) id<AspectToken> test1Token;
    @property (nonatomic,strong) id<AspectToken> test2Token;
    @end
    
    @implementation ViewController
    
    - (void)viewDidLoad {
        [super viewDidLoad];
        self.test0Token;
        self.test1Token;
        self.test2Token;
        // Do any additional setup after loading the view.
       NSString *tmp0 = [[AspectTest shareTest] test0];
       NSLog(@"%@",tmp0);
       NSString *tmp1 =   [[AspectTest shareTest] test1:@"test1"];
       NSLog(@"%@",tmp1);
       NSString *tmp2 =  [[AspectTest shareTest] test2:@"test2" bbb:@"bbb"];
       NSLog(@"%@",tmp2);
        
        
        
    }
    
    
    -(void)dealloc{
        [self.test0Token remove];
        [self.test1Token remove];
        [self.test2Token remove];
    }
    
    -(id<AspectToken>)test0Token{
        
        return [[AspectTest shareTest] aspect_hookSelector:@selector(test0) withOptions:AspectPositionInstead usingBlock:^(id<AspectInfo> info){
            
            NSString  *data = @"aspectTest0bbbbbbbb";
            NSInvocation *invocation = info.originalInvocation;
            [invocation setReturnValue:&data];
        } error:NULL];
        
        
    }
    
    -(id<AspectToken>)test1Token{
        
        return [[AspectTest shareTest] aspect_hookSelector:@selector(test1:) withOptions:AspectPositionBefore usingBlock:^(id<AspectInfo> info, NSString *test1){
          NSString *  test2 = @"ljfkdsajkfljasklfjdks";
            NSInvocation *invocation = info.originalInvocation;
            [invocation setArgument:&test2 atIndex:2];
        } error:NULL];
        
    }
    
    -(id<AspectToken>)test2Token{
        
        return [[AspectTest shareTest] aspect_hookSelector:@selector(test2:bbb:) withOptions:AspectPositionAfter usingBlock:^(id<AspectInfo> info,NSString *test2, NSString* bbb){
            NSString  *data = [[@"aspectTest2" stringByAppendingString:test2] stringByAppendingString:bbb];
            NSInvocation *invocation = info.originalInvocation;
            [invocation invoke];
        } error:NULL];
        
    }
    
    @end
