簡述

借助PYPhotoBrowser 和YangMingShan共同組合成圖片選擇和圖片展示的實(shí)用開發(fā)功能。

介紹

PYPhotoBrowser:圖片未發(fā)布之前，圖片本地預(yù)覽和刪除。
YangMingShan:相冊選擇訪問嵌溢，相機(jī)使用。

使用方法

創(chuàng)建PYPhotosView(九宮格類型/直線類型)

PYPhotosView *squPhotosView = [PYPhotosView photosView];
squPhotosView.photosState = PYPhotosViewStateWillCompose;
squPhotosView.photoWidth =  80;
squPhotosView.photoHeight = 80;
squPhotosView.py_x = 20;
squPhotosView.py_y = 100;
squPhotosView.delegate = self;
[self.view addSubview:squPhotosView];

PYPhotosView *recPhotosView = [PYPhotosView photosView];
recPhotosView.photosState = PYPhotosViewStateWillCompose;
recPhotosView.photosMaxCol = 9;
recPhotosView.photoWidth = 80;
recPhotosView.photoHeight = 80;
recPhotosView.py_x = 20;
recPhotosView.py_y = 300;
recPhotosView.delegate = self;
[self.view addSubview:recPhotosView];

PYPhotosView代理方法請求打開相冊相機(jī)

- (void)photosView:(PYPhotosView *)photosView didAddImageClickedWithImages:(NSMutableArray *)images {
    [self yms_presentCustomAlbumPhotoView:self.pickerViewController delegate:self];
}

訪問相機(jī)相冊

-(void)photoPickerViewControllerDidReceivePhotoAlbumAccessDenied:(YMSPhotoPickerViewController *)picker {
    UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"允許訪問相冊？" message:@"需要你的允許訪問相冊" preferredStyle:UIAlertControllerStyleAlert];
    UIAlertAction *dismissAction = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:nil];
    UIAlertAction *settingsAction = [UIAlertAction actionWithTitle:@"去設(shè)置" 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:@"允許訪問相機(jī)漓踢？" message:@"需要你的允許訪問相機(jī)" preferredStyle:UIAlertControllerStyleAlert];
    UIAlertAction *dismissAction = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:nil];
    UIAlertAction *settingsAction = [UIAlertAction actionWithTitle:@"去設(shè)置" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];
    }];
    [alertController addAction:dismissAction];
    [alertController addAction:settingsAction];
    [picker presentViewController:alertController animated:YES completion:nil];
}

獲得選中照片

- (void)photoPickerViewController:(YMSPhotoPickerViewController *)picker didFinishPickingImages:(NSArray *)photoAssets {
    [picker dismissViewControllerAnimated:YES completion:^() {
        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) {
            [imageManager requestImageDataForAsset:asset options:options resultHandler:^(NSData * _Nullable imageData, NSString * _Nullable dataUTI, UIImageOrientation orientation, NSDictionary * _Nullable info) {
                [mutableImages addObject:[UIImage imageWithData:imageData]];
            }];
        }
        [self.recPhotosView setImages:mutableImages]; //將照片賦值給PhotosView
    }];
}

注意：1.在plist文件中添加獲取相冊相機(jī)權(quán)限字段。2.需要所有圖片上傳時(shí)和簸，通過自定義photoView.images獲得彭雾。3.pickerViewController自定義請查看YangMingShan。
