MJPhotoBrowser 用法

一、使用方法:

 

#import "MJPhotoBrowser.h"

#import "MJPhoto.h"

 

- (void)tapPhoto:(UITapGestureRecognizer *)recognizer

{

    //1.创建图片浏览器

    MJPhotoBrowser *brower = [[MJPhotoBrowser alloc] init];

   

    //2.告诉图片浏览器显示所有的图片

    NSMutableArray *photos = [NSMutableArray array];

    for (int i = 0 ; i < self.photos.count; i++) {

        Photo *pic = self.photos[i];

        //传递数据给浏览器

        MJPhoto *photo = [[MJPhoto alloc] init];

        photo.url = [NSURL URLWithString:pic.bmiddle_pic];

        photo.srcImageView = self.subviews[i]; //设置来源哪一个UIImageView

        [photos addObject:photo];

    }

    brower.photos = photos;

   

    //3.设置默认显示的图片索引

    brower.currentPhotoIndex = recognizer.view.tag;

   

    //4.显示浏览器

    [brower show];

}

 

 

二、我用到的具体实例：

 

1）腾讯聊天cell中获取第几张照片，并打开图像浏览器

 

- (void)TecentChatImageCellShouldShowFullScreen:(TecentChatImageCell *)cell

{

    MJPhotoBrowser *browser = [[MJPhotoBrowseralloc] init];

   

    browser.currentPhotoIndex = [selfgetPicUrl:cell.indexPath.row];//获取播放第几个图片

   

    browser.photos = _localPicMsgArray;//数组中的是MJPhoto对象

    [browser show];

    //当键盘拉起的时候, 需要关闭键盘, 否则图片显示一半

    [selfdoEndEditGesture];

}

 

2）方法来返回第几个元素

 

- (NSInteger)getPicUrl:(NSInteger)dd

{

    NSInteger c = 0;

    NSInteger d = 0;

    [_localPicMsgArrayremoveAllObjects];

    for (int i=0;i<self.dataSource.count;++i) {

        id model = self.dataSource[i];

        NSInteger type = [NSDictionary_Number_Object_ForKey(model, @"type") integerValue];

        if (type == MESSAGE_TYPE_IMAGE) {

            NSString* imageURL = [model objectForKey:@"imageURLpath"];//远程URL的image

            NSString* imagePath = [model objectForKey:@"path"];//本地URL的image

            MJPhoto *photo = [[MJPhotoalloc] init];

            if (IS_NS_STRING_EMPTY(imageURL)) {

                //通过本地URL来查找iamge的方法

                for (IDSPicSendModel *picModel in_localPicImageMsgArray) {

                    if ([picModel.picPathisEqualToString:imagePath]) {

                        photo.image = picModel.picImage;

                        NSLog(@"%@",picModel.picPath);

                        break;

                    }

                }

            }

            else {

                //取远程URL方法

                photo.url = [NSURLURLWithString:imageURL];

            }

            [_localPicMsgArraycl_addObject:photo];

            if (i == dd) {

                c = d;

            }

            ++d;

        }

    }

    //返回的是第几个图片元素

    return c;

}
