    1、在文件SDBrowserImageView.m中有用SDWebImage到网络加载图片 需要的注释去掉即可

     

    #import "ViewController.h"
    #import "SDPhotoBrowser.h"
    @interface ViewController ()<SDPhotoBrowserDelegate>
    {
        NSMutableArray * arrayImage;
    }
    @end
    
    @implementation ViewController
    
    - (void)viewDidLoad {
        [super viewDidLoad];
        
        
        [self CreatUI];
        
        
    }
    
    -(void)CreatUI{
        
        arrayImage = [NSMutableArray new];
        for  (int i = 0; i<9; i++) {
            
            UIImageView * imaVi = [[UIImageView alloc] initWithFrame:CGRectMake(i%3*90+20,i/3*100+50, 80, 80)];
            imaVi.tag = i;
            imaVi.userInteractionEnabled = YES;
            UITapGestureRecognizer * tap = [[UITapGestureRecognizer alloc]init];
            
            [tap addTarget:self action:@selector(tapaction:)];
            
            [imaVi addGestureRecognizer:tap];
            imaVi.image = [UIImage imageNamed:[NSString stringWithFormat:@"%d.jpg",i+1]];
            [self.view addSubview:imaVi];
            
            [arrayImage addObject:[NSString stringWithFormat:@"%d.jpg",i+1]];
            
        }
        
        
    }
    
    
    -(void)tapaction:(UITapGestureRecognizer*)tap{
        
        UIView * vi = tap.view;
        SDPhotoBrowser * broser = [[SDPhotoBrowser alloc] init];
        broser.currentImageIndex = vi.tag;
        broser.sourceImagesContainerView = self.view;
        broser.imageCount =arrayImage.count;
        broser.delegate = self;
        [broser show];
        
        
        
    }
