TZImagePickerControllerDemo

项目介绍

TZImagePickerControllerDemo

Podfile新增行 pod 'TZImagePickerController'

使用之前导入头文件 #import <TZImagePickerController.h>

使用说明

1. 定义 类变量：
  UIImagePickerController* picker_library_;
2.实现 UIImagePickerControllerDelegate 这个delegate，还需要UINavigationControllerDelegate 这个代理
3. 以模态的方式，显示 图片选取器

picker_library_ = [[UIImagePickerController alloc] init];  
        picker_library_.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;  
        picker_library_.allowsEditing = YES;  
        picker_camera_.allowsImageEditing=YES;  
        picker_library_.delegate = self;  
        [self presentModalViewController: picker_library_  
                                animated: YES];

其中，sourceType 指定了 几种 图片的来源：
UIImagePickerControllerSourceTypePhotoLibrary：表示显示所有的照片
UIImagePickerControllerSourceTypeCamera：表示从摄像头选取照片
UIImagePickerControllerSourceTypeSavedPhotosAlbum：表示仅仅从相册中选取照片。
allowEditing和allowsImageEditing 设置为YES，表示 允许用户编辑图片，否则，不允许用户编辑。

选照片

//MaxImagesCount  可以选着的最大条目数
    TZImagePickerController *imagePicker = [[TZImagePickerController alloc] initWithMaxImagesCount:1 delegate:self];

    // 是否显示可选原图按钮
    imagePicker.allowPickingOriginalPhoto = NO;
    // 是否允许显示视频
    imagePicker.allowPickingVideo = NO;
    // 是否允许显示图片
    imagePicker.allowPickingImage = YES;

    // 这是一个navigation 只能present
    [self presentViewController:imagePicker animated:YES completion:nil];

选择照片的回调

// 选择照片的回调
-(void)imagePickerController:(TZImagePickerController *)picker
      didFinishPickingPhotos:(NSArray<UIImage *> *)photos
                sourceAssets:(NSArray *)assets
       isSelectOriginalPhoto:(BOOL)isSelectOriginalPhoto{

}

选视频

//MaxImagesCount  可以选着的最大条目数
    TZImagePickerController *imagePicker = [[TZImagePickerController alloc] initWithMaxImagesCount:2 delegate:self];

    // 是否显示可选原图按钮
    imagePicker.allowPickingOriginalPhoto = NO;
    // 是否允许显示视频
    imagePicker.allowPickingVideo = YES;
    // 是否允许显示图片
    imagePicker.allowPickingImage = NO;

    // 这是一个navigation 只能present
    [self presentViewController:imagePicker animated:YES completion:nil];

选择视频的回调

// 选择视频的回调
-(void)imagePickerController:(TZImagePickerController *)picker
       didFinishPickingVideo:(UIImage *)coverImage
                sourceAssets:(PHAsset *)asset{

}
