与 UIImagePickerController 几乎完全一致的接口调用方式，上手容易
使用 Photos 框架异步加载图片，内存消耗低

屏幕截图

系统支持

iOS 8.0+
Xcode 7.0

安装

使用

Objective-C

导入框架

@import HMImagePicker;

在私有扩展中定义属性

@interface MainViewController () <HMImagePickerControllerDelegate>
/// 选中照片数组
@property (nonatomic) NSArray *images;
/// 选中资源素材数组，用于定位已经选择的照片
@property (nonatomic) NSArray *selectedAssets;
@end

在选择按钮的方法中，实现以下代码

- (IBAction)clickSelectPhotoButton {
    HMImagePickerController *picker = [[HMImagePickerController alloc] initWithSelectedAssets:self.selectedAssets];

    // 设置图像选择代理
    picker.pickerDelegate = self;
    // 设置目标图片尺寸
    picker.targetSize = CGSizeMake(600, 600);
    // 设置最大选择照片数量
    picker.maxPickerCount = 9;

    [self presentViewController:picker animated:YES completion:nil];
}

遵守协议

@interface MainViewController () <HMImagePickerControllerDelegate>

实现协议方法

#pragma mark - HMImagePickerControllerDelegate
- (void)imagePickerController:(HMImagePickerController *)picker
      didFinishSelectedImages:(NSArray<UIImage *> *)images
               selectedAssets:(NSArray<PHAsset *> *)selectedAssets {

    // 记录图像，方便在 CollectionView 显示
    self.images = images;
    // 记录选中资源集合，方便再次选择照片定位
    self.selectedAssets = selectedAssets;

    [self.collectionView reloadData];

    [self dismissViewControllerAnimated:YES completion:nil];
}
