使用方法

安装

手动

下载并将GMImagePicker文件夹导入到您的项目中。

导入头文件

#import "GMImagePickerController.h"

初始化选择器、设置委托并展示它。

    GMImagePickerController *picker = [[GMImagePickerController alloc] init];
    picker.delegate = self;
    [self presentViewController:picker animated:YES completion:nil];

委托

在您的类中实现GMImagePickerControllerDelegate协议

@interface YourViewController : UIViewController <GMImagePickerControllerDelegate>

实现didFinishPickingAssets委托方法。请注意，当操作完成时，您负责关闭选择器，并处理返回的(NSArray *)assetArray

- (void)assetsPickerController:(GMImagePickerController *)picker didFinishPickingAssets:(NSArray *)assetArray
{
    [picker.presentingViewController dismissViewControllerAnimated:YES completion:nil];
    NSLog(@"GMImagePicker: User ended picking assets. Number of selected items is: %lu", (unsigned long)assetArray.count);
}

您还可以实现可选的assetsPickerControllerDidCancel

-(void)assetsPickerControllerDidCancel:(GMImagePickerController *)picker
{
    NSLog(@"GMImagePicker: User pressed cancel button");
}

自定义

在展示选择器之前，您可以自定义一些属性

    ...
    //Display or not the selection info Toolbar:
    picker.displaySelectionInfoToolbar = YES;

    //Display or not the number of assets in each album:
    picker.displayAlbumsNumberOfAssets = YES;

    //Customize the picker title and prompt (helper message over the title)
    picker.title = @"Custom title";
    picker.customNavigationBarPrompt = @"Custom helper message!";

    //Customize the number of cols depending on orientation and the inter-item spacing
    picker.colsInPortrait = 3;
    picker.colsInLandscape = 5;
    picker.minimumInteritemSpacing = 2.0;

    //You can pick the smart collections you want to show:
    _customSmartCollections = @[@(PHAssetCollectionSubtypeSmartAlbumFavorites),
                                @(PHAssetCollectionSubtypeSmartAlbumRecentlyAdded),
                                @(PHAssetCollectionSubtypeSmartAlbumVideos),
                                @(PHAssetCollectionSubtypeSmartAlbumSlomoVideos),
                                @(PHAssetCollectionSubtypeSmartAlbumTimelapses),
                                @(PHAssetCollectionSubtypeSmartAlbumBursts),
                                @(PHAssetCollectionSubtypeSmartAlbumPanoramas)];
    ...

作为iPad的Popover使用

也可作为iPad的Popover使用（可自定义大小）

Screenshot

此代码在iPhone和iPad上均适用

    ...
    GMImagePickerController *picker = [[GMImagePickerController alloc] init];
    picker.delegate = self;

    picker.title = @"Custom title";
    picker.customNavigationBarPrompt = @"Custom helper message!";
    picker.colsInPortrait = 3;
    picker.colsInLandscape = 5;
    picker.minimumInteritemSpacing = 2.0;
    picker.modalPresentationStyle = UIModalPresentationPopover;

    UIPopoverPresentationController *popPC = picker.popoverPresentationController;
    popPC.permittedArrowDirections = UIPopoverArrowDirectionAny;
    popPC.sourceView = _gmImagePickerButton;
    popPC.sourceRect = _gmImagePickerButton.bounds;

    [self showViewController:picker sender:nil];

最低要求
