iOS - 相册多选图片

1.在pod中导入三方工具：

pod 'TZImagePickerController'

2.调用相册：

在页面引入：
#import <TZImagePickerController.h>
代理方法<TZImagePickerControllerDelegate>

// 相册
- (void)photoClick{

    NSInteger Count =  9 - self.dataSource.count;//剩余可选图片数量
    TZImagePickerController *imagePickerVc = [[TZImagePickerController alloc] initWithMaxImagesCount:Count delegate:self];
    [imagePickerVc setDidFinishPickingPhotosHandle:^(NSArray<UIImage *> *photo, NSArray * assets, BOOL isSelectOriginalPhoto) {
        NSMutableArray *imgAry = [@[] mutableCopy];
        for (NSInteger i = 0; i<photo.count; i++) {
            UIImage *img = [ImageUtil zipImgWithImage:photo[i]];//压缩图片
            [imgAry addObject:img];
        }
       
    }];
    [self presentViewController:imagePickerVc animated:YES completion:nil];

}

3.顺便说下调用相机：

// 相机
- (void)cameraClick{

    NSUInteger sourceType = 0;
    // 判断系统是否支持相机
    UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
    if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
        imagePickerController.delegate = self; //设置代理
        imagePickerController.allowsEditing = NO;
        imagePickerController.sourceType = sourceType; //图片来源
        //拍照
        sourceType = UIImagePickerControllerSourceTypeCamera;
        imagePickerController.sourceType = sourceType;
        [self presentViewController:imagePickerController animated:YES completion:nil];
    }

}


// 获取图片
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    [picker dismissViewControllerAnimated:YES completion:^{}];
    UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage]; //通过key值获取到图片
    UIImage *img = [GlobelConfig imageCompressToData:image];//压缩图片

}
