本文详细介绍了如何使用SDPhotoBrowser图片浏览器组件在iOS应用中实现图片预览和网络图片加载功能。通过实例代码展示了如何创建图片视图、设置触摸事件、初始化浏览器并展示图片。同时，提供了本地图片预览的实现方法。

SDPhotoBrowser。Demo

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];
    
    
    
}
