Xamarin Binding Library - Yahoo:YangMingShan

YangMingShan - Xamarin iOS Binding Library

YangMingShan is a collection of iOS UI components that we created while building Yahoo apps. The reason we open source it is to share useful and common components with the community. Feel free to open the feature request ticket for new UI component you see on Yahoo apps or send pull-request to benefit open source community.

The Components

A

YMSPhotoPicker

YMSPhotoPicker is an UIComponent that let you select multiple photos from your albums. You can also take a photo inside YMSPhotoPicker and select it with other photos. It has the exposed theme YMSPhotoPickerTheme that you can customize several parts of YMSPhotoPicker.

Part of the code in this package was derived from Yahoo Messenger and Yahoo Taiwan Auctions.

Usage

Add NSPhotoLibraryUsageDescription and NSCameraUsageDescription to your App Info.plist to specify the reason for accessing photo library and camera. See Cocoa Keys for more details.

#####Objective-C

Import

@import YangMingShan;

Add delegate to your view controller

@interface YourViewController ()<YMSPhotoPickerViewControllerDelegate>

Present default photo picker. Note it is only available for single selection

[self yms_presentAlbumPhotoViewWithDelegate:self];

Or init picker with limited photo selection of 10

YMSPhotoPickerViewController *pickerViewController = [[YMSPhotoPickerViewController alloc] init];
pickerViewController.numberOfPhotoToSelect = 10;

With customized theme

UIColor *customColor = [UIColor colorWithRed:64.0/255.0 green:0.0 blue:144.0/255.0 alpha:1.0];
UIColor *customCameraColor = [UIColor colorWithRed:86.0/255.0 green:1.0/255.0 blue:236.0/255.0 alpha:1.0];

pickerViewController.theme.titleLabelTextColor = [UIColor whiteColor];
        pickerViewController.theme.navigationBarBackgroundColor = customColor;
pickerViewController.theme.tintColor = [UIColor whiteColor];
pickerViewController.theme.orderTintColor = customCameraColor;
pickerViewController.theme.cameraVeilColor = customCameraColor;
pickerViewController.theme.cameraIconColor = [UIColor whiteColor];
pickerViewController.theme.statusBarStyle = UIStatusBarStyleLightContent;

Present customized picker

[self yms_presentCustomAlbumPhotoView:pickerViewController delegate:self];

Implement photoPickerViewControllerDidReceivePhotoAlbumAccessDenied: and photoPickerViewControllerDidReceiveCameraAccessDenied: to observe photo album and camera access denied occur

- (void)photoPickerViewControllerDidReceivePhotoAlbumAccessDenied:(YMSPhotoPickerViewController *)picker
{
    UIAlertController *alertController = [UIAlertController alertControllerWithTitle:NSLocalizedString(@"Allow photo album access?", nil) message:NSLocalizedString(@"Need your permission to access photo albums", nil) preferredStyle:UIAlertControllerStyleAlert];
    UIAlertAction *dismissAction = [UIAlertAction actionWithTitle:NSLocalizedString(@"Cancel", nil) style:UIAlertActionStyleCancel handler:nil];
    UIAlertAction *settingsAction = [UIAlertAction actionWithTitle:NSLocalizedString(@"Settings", nil) style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];
    }];
    [alertController addAction:dismissAction];
    [alertController addAction:settingsAction];

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

- (void)photoPickerViewControllerDidReceiveCameraAccessDenied:(YMSPhotoPickerViewController *)picker
{
    UIAlertController *alertController = [UIAlertController alertControllerWithTitle:NSLocalizedString(@"Allow camera access?", nil) message:NSLocalizedString(@"Need your permission to take a photo", nil) preferredStyle:UIAlertControllerStyleAlert];
    UIAlertAction *dismissAction = [UIAlertAction actionWithTitle:NSLocalizedString(@"Cancel", nil) style:UIAlertActionStyleCancel handler:nil];
    UIAlertAction *settingsAction = [UIAlertAction actionWithTitle:NSLocalizedString(@"Settings", nil) style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];
    }];
    [alertController addAction:dismissAction];
    [alertController addAction:settingsAction];

    // The access denied of camera is always happened on picker, present alert on it to follow the view hierarchy
    [picker presentViewController:alertController animated:YES completion:nil];
}

Implement photoPickerViewController:didFinishPickingImages: while you expect there are multiple photo selections

- (void)photoPickerViewController:(YMSPhotoPickerViewController *)picker didFinishPickingImages:(NSArray *)photoAssets
{
    [picker dismissViewControllerAnimated:YES completion:^() {
        // Remember images you get here is PHAsset array, you need to implement PHImageManager to get UIImage data by yourself
        PHImageManager *imageManager = [[PHImageManager alloc] init];

        PHImageRequestOptions *options = [[PHImageRequestOptions alloc] init];
        options.deliveryMode = PHImageRequestOptionsDeliveryModeHighQualityFormat;
        options.networkAccessAllowed = YES;
        options.resizeMode = PHImageRequestOptionsResizeModeExact;
        options.synchronous = YES;

        NSMutableArray *mutableImages = [NSMutableArray array];

        for (PHAsset *asset in photoAssets) {
            CGSize targetSize = CGSizeMake((CGRectGetWidth(self.collectionView.bounds) - 20*2) * [UIScreen mainScreen].scale, (CGRectGetHeight(self.collectionView.bounds) - 20*2) * [UIScreen mainScreen].scale);
            [imageManager requestImageForAsset:asset targetSize:targetSize contentMode:PHImageContentModeAspectFill options:options resultHandler:^(UIImage *image, NSDictionary *info) {
                [mutableImages addObject:image];
            }];
        }

		// Assign to Array with images
        self.images = [mutableImages copy];
    }];
}

yangmingshan-ios-binding's Issues

Navigation Bar

Does it support iPhone X? Seems like the navigation bar is missing.
