我在我的应用程序中使用了 ELCImagePicker 我遇到了两个问题，第一个问题是画廊出现的视图不等于 iPhone 或 iPad 的宽度，比如图像爆炸，第二个问题是画廊中出现的图像像素化而不是正常分辨率。在此处输入图像描述

//----------------------------------------------------
//imagePicker Zone
- (IBAction)uploadImageActionButton:(id)sender {

    ELCImagePickerController *elcPicker = [[ELCImagePickerController alloc] initImagePicker];

    elcPicker.maximumImagesCount = 5; //Set the maximum number of images to select to 100
    elcPicker.returnsOriginalImage = YES; //Only return the fullScreenImage, not the fullResolutionImage
    elcPicker.returnsImage = YES; //Return UIimage if YES. If NO, only return asset location information
    elcPicker.onOrder = YES; //For multiple image selection, display and return order of selected images
    elcPicker.mediaTypes = @[(NSString *)kUTTypeImage, (NSString *)kUTTypeMovie]; //Supports image and movie types

    elcPicker.imagePickerDelegate = self;

    [self presentViewController:elcPicker animated:YES completion:nil];
}
- (void)elcImagePickerController:(ELCImagePickerController *)picker didFinishPickingMediaWithInfo:(NSArray *)info
{//yes
    [self dismissViewControllerAnimated:YES completion:nil];

//    
    NSMutableArray *images = [NSMutableArray arrayWithCapacity:[info count]];
     NSMutableArray *name = [NSMutableArray arrayWithCapacity:[info count]];
    NSMutableArray *path = [NSMutableArray arrayWithCapacity:[info count]];
    NSString *aDocumentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
    NSInteger anIndex = 0;

    for(NSDictionary *dict in info) {
        UIImage *image = [dict objectForKey:UIImagePickerControllerOriginalImage];
        [images addObject:image];

        UIImageView *imageview = [[UIImageView alloc] initWithImage:image];
        [imageview setContentMode:UIViewContentModeScaleAspectFit];
        // Save Image
        NSString *anImageName = [NSString stringWithFormat:@"%ld.jpg", 1+(long)anIndex++];
        NSString *anImagePath = [NSString stringWithFormat:@"%@/%@", aDocumentsDirectory, anImageName];

        NSData *anImageData = UIImageJPEGRepresentation(image, 0.5);
        [anImageData writeToFile:anImagePath atomically:YES];
        [path addObject:anImagePath];
        [images addObject:anImageData];
    }

    _chosenImages=images;
    _chosenImagesName=name;
    _chosenImagesPath=path;
    NSLog(@"name %@",_chosenImagesName);

}

- (void)elcImagePickerControllerDidCancel:(ELCImagePickerController *)picker
{//yes
    [self dismissViewControllerAnimated:YES completion:nil];
}
