将UIImagePickerViewController中的图像添加到UITableViewCell中的UICollectionView中

Question

起初，对于我长期的问题感到抱歉。
我正在用UICollectionView在里面创建一个自定义的UITableViewCell。每当用户选择这个单元格时，UIImagePickerController就会出现，现在我想将所有选定的图像从UIImagePickerController传递到我的自定义单元格内的UICollectionView。
我已完成显示图像选择器，现在我的问题是在集合视图中显示选定的图像。
我该怎么做？
我的代码：

SHImageUploadCell.h

#import <UIKit/UIKit.h> 
@class SHImageUploadCell; 
@protocol SHImagUploadDelegate<NSObject> 
@optional 
- (void)closeImage:(SHImageUploadCell*)cell; 
@end 
@interface SHImageUploadCell : UICollectionViewCell 
@property (weak, nonatomic) IBOutlet UIImageView *imgUpload; 
@property (strong,nonatomic) id<SHImagUploadDelegate> delegate; 
@property(nonatomic) int imageIndex; 
@property (weak, nonatomic) IBOutlet UIImageView *bugImage; 

@end 

SHImageUploadCell.m

#import "SHImageUploadCell.h" 

@implementation SHImageUploadCell 
- (IBAction)bntDeleteImageClick:(id)sender { 


    NSDictionary* userInfo = @{@"index": @(self.imageIndex)}; 

    NSLog(@"%d", self.imageIndex); 
    if (_delegate) { 
     [_delegate closeImage:self]; 
    } 
} 

@end 

MyCustomCell.h

#import <UIKit/UIKit.h> 

@interface SHPhotoPickerViewCell : UITableViewCell 
@property (weak, nonatomic) IBOutlet UICollectionView *photoCollection; 
@property (strong, nonatomic) NSMutableArray *listImage; 
@end 

MyCustomCell.m

#import "SHPhotoPickerViewCell.h" 
#import "SHImageUploadCell.h" 

@interface SHPhotoPickerViewCell()<UICollectionViewDataSource, UICollectionViewDelegate, SHImagUploadDelegate> 

@end 

@implementation SHPhotoPickerViewCell 

- (void)awakeFromNib { 
    [super awakeFromNib]; 
    // Initialization code 
    [self.photoCollection registerClass:[SHImageUploadCell class] forCellWithReuseIdentifier:@"selectedCell"]; 
    [self.photoCollection registerNib:[UINib nibWithNibName:@"SHImageUploadCell" bundle:[NSBundle mainBundle]] forCellWithReuseIdentifier:@"selectedCell"]; 
} 

- (void)setSelected:(BOOL)selected animated:(BOOL)animated { 
    [super setSelected:selected animated:animated]; 

    // Configure the view for the selected state 
} 

- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section{ 
    return self.listImage.count; 
} 

-(UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath { 
    SHImageUploadCell *uploadCell = [collectionView dequeueReusableCellWithReuseIdentifier:@"uploadCell" forIndexPath:indexPath]; 
    uploadCell.imgUpload.image = [UIImage imageWithData: self.listImage[indexPath.row]]; 
    uploadCell.imageIndex = (int)indexPath.row; 
    uploadCell.delegate=self; 
    return uploadCell; 
} 

@end 

手柄电池选择：

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { 
if (indexPath.row == 4){ 
    UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init]; 
    imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; 
    imagePickerController.delegate = self; 
    [self presentViewController:imagePickerController animated:YES completion:nil]; 
    } 
    } 
} 

的UIImagePickerController委托：

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info 
{ 
    SHPhotoPickerViewCell *photoPickerCell = [self.tableView cellForRowAtIndexPath:[NSIndexPath indexPathForRow:self.pickerCellIndexPath.row inSection:1]]; 
    UIImage *image = [info valueForKey:UIImagePickerControllerOriginalImage]; 
    image = [SHHelper resizeImageWithImage:image toSize:CGSizeMake(480, 320)]; 
    NSData *imageData = UIImageJPEGRepresentation(image, 0.7); 
    photoPickerCell.listImage = [NSMutableArray new]; 
    [photoPickerCell.listImage addObject:imageData]; 

    [photoPickerCell.photoCollection reloadData]; 

    [picker dismissViewControllerAnimated:YES completion:^{ 

    }]; 


}

试试这个：

-(UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath { 

    id object = [listImage objectAtIndex:indexPath.row]; 
    if ([object isKindOfClass:[UIImage class]]) { 
     uploadCell.imgUpload.image = (UIImage *)object; 
    } 
    else{ 
     uploadCell.imgUpload.image = [UIImage imageWithData: object]; 
    } 

     return uploadCell; 
} 

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info 
{ 
    UIImage *image = [info valueForKey:UIImagePickerControllerOriginalImage]; 
    [listImage addObject:image]; // here add image which you selected 
    // reload tableview 
    // reload collection view 
    [picker dismissViewControllerAnimated:YES completion:^{ 

    }]; 


}
