Ios 如何获取照片库图像计数

从Photolibrary提取图像我们使用UIImagePickerController和UIImagePickerController源类型Photolibrary进入Photolibrary并获取图像，现在我的问题是如何获取保存在我的Photolibrary中的图像计数

---

允许我在应用程序中显示图像计数

是允许您使用以下方法获取所有图像：- 导入照片框架

#import <Photos/Photos.h>


-(void)getAllPhotosFromCamera
{
imageArray=[[NSArray alloc] init];
mutableArray =[[NSMutableArray alloc]init];

PHImageRequestOptions *requestOptions = [[PHImageRequestOptions alloc] init];
requestOptions.resizeMode   = PHImageRequestOptionsResizeModeFast;
requestOptions.deliveryMode = PHImageRequestOptionsDeliveryModeHighQualityFormat;
requestOptions.synchronous = true;
PHFetchResult *result = [PHAsset fetchAssetsWithMediaType:PHAssetMediaTypeImage options:nil];

NSLog(@"%d",(int)result.count);

PHImageManager *manager = [PHImageManager defaultManager];
NSMutableArray *images = [NSMutableArray arrayWithCapacity:[result count]];

// assets contains PHAsset objects.

__block UIImage *ima;
for (PHAsset *asset in result)
{
    // Do something with the asset

    [manager requestImageForAsset:asset
                       targetSize:PHImageManagerMaximumSize
                      contentMode:PHImageContentModeDefault
                          options:requestOptions
                    resultHandler:^void(UIImage *image, NSDictionary *info)
                    {
                        ima = image;

                        [images addObject:ima];
                    }];
}

imageArray = [images copy];
[_cView reloadData];
}

#import <Photos/Photos.h>

#导入
-（无效）从照相机获取所有照片
{
imageArray=[[NSArray alloc]init]；
mutableArray=[[NSMutableArray alloc]init]；
PHImageRequestOptions*requestOptions=[[PHImageRequestOptions alloc]init]；
requestOptions.resizeMode=PhImageRequestOptions ResizeModeFast；
requestOptions.deliveryMode=PhImageRequestOptions DeliveryModeHighQualityFormat；
requestOptions.synchronous=true；
PHFetchResult*result=[PHAsset FETCHASSETSWITMEDIATYPE:PHASSETMEDIATYPE图像选项：nil]；
NSLog（@“%d”，（int）result.count）；
PHImageManager*管理器=[PHImageManager默认管理器]；
NSMutableArray*图像=[NSMutableArray阵列容量：[结果计数]]；
//资源包含相集对象。
__块UIImage*ima；
用于（相位集*结果中的资产）
{
//对资产做些什么
[manager requestImageForAsset:资产
targetSize:PHImageManagerMaximumSize
contentMode:PHImageContentModeDefault
选项：请求选项
resultHandler:^void（UIImage*图像，NSDictionary*信息）
{
ima=图像；
[图像添加对象：ima]；
}];
}
imageArray=[图像复制]；
[[u cView reloadData]；
}

如果您想获得计数，那么通过照片框架，您可以获得如下计数

PHFetchResult *allPhotosResult = [PHAsset fetchAssetsWithMediaType:PHAssetMediaTypeImage options:nil];
NSLog(@"count of All Photos from Moments in iOS8, or Camera Roll - %lu",(unsigned long)allPhotosResult.count);

也不要忘记导入照片框架

#import <Photos/Photos.h>


-(void)getAllPhotosFromCamera
{
imageArray=[[NSArray alloc] init];
mutableArray =[[NSMutableArray alloc]init];

PHImageRequestOptions *requestOptions = [[PHImageRequestOptions alloc] init];
requestOptions.resizeMode   = PHImageRequestOptionsResizeModeFast;
requestOptions.deliveryMode = PHImageRequestOptionsDeliveryModeHighQualityFormat;
requestOptions.synchronous = true;
PHFetchResult *result = [PHAsset fetchAssetsWithMediaType:PHAssetMediaTypeImage options:nil];

NSLog(@"%d",(int)result.count);

PHImageManager *manager = [PHImageManager defaultManager];
NSMutableArray *images = [NSMutableArray arrayWithCapacity:[result count]];

// assets contains PHAsset objects.

__block UIImage *ima;
for (PHAsset *asset in result)
{
    // Do something with the asset

    [manager requestImageForAsset:asset
                       targetSize:PHImageManagerMaximumSize
                      contentMode:PHImageContentModeDefault
                          options:requestOptions
                    resultHandler:^void(UIImage *image, NSDictionary *info)
                    {
                        ima = image;

                        [images addObject:ima];
                    }];
}

imageArray = [images copy];
[_cView reloadData];
}

#import <Photos/Photos.h>

#导入

在这里您可以获得所有图像计数。它还包括所有相册和相机卷图像

__block NSInteger intTotalCount=0;
// Get all Album list...
PHFetchResult *userAlbums = [PHAssetCollection fetchAssetCollectionsWithType:PHAssetCollectionTypeAlbum subtype:PHAssetCollectionSubtypeAny options:nil];
[userAlbums enumerateObjectsUsingBlock:^(PHAssetCollection *collection, NSUInteger idx1, BOOL *stop) {
    PHFetchResult *assetsFetchResult = [PHAsset fetchAssetsInAssetCollection:collection options:nil];
    intTotalCount+=assetsFetchResult.count;
}];

// Get image count from Camera Roll
PHFetchOptions *allPhotosOptions = [PHFetchOptions new];
allPhotosOptions.predicate = [NSPredicate predicateWithFormat:@"mediaType == %d ",PHAssetMediaTypeImage];
PHFetchResult *allPhotosResult = [PHAsset fetchAssetsWithOptions:allPhotosOptions];
intTotalCount+=allPhotosResult.count;

NSLog(@"%d",intTotalCount);
