Question

我正在为iPhone制作应用程序，并希望让用户能够从他们的照片库中多选图像。我已经有一个工作代码供用户一次选择四个图像。但我不能一次选择2或3个图像。我想一次选择2或3个图像。我正在尝试以下代码。请帮助我任何人。

- (id)initImagePicker
{    
    ELCAlbumPickerController *albumPicker = [[ELCAlbumPickerController alloc] initWithStyle:UITableViewStylePlain];    
    self = [super initWithRootViewController:albumPicker]; 
    if (self) 
    {          
        self.maximumImagesCount = 4; 
        [albumPicker setParent:self];
    }     
    else if (self)   
    {          
        self.minimumImageCount=1;        
        [albumPicker setParent:self];  
    }      
    return self;
}

- (id)initWithRootViewController:(UIViewController *)rootViewController
{  
    self = [super initWithRootViewController:rootViewController]; 
    if (self) 
        self.maximumImagesCount = 4;        
    else if (self)
        self.minimumImageCount=1;   
    return self;
}

-(void)choosePhotoFromExistingImages
{
    ELCImagePickerController *elcPicker = [[ELCImagePickerController alloc] initImagePicker];  
    elcPicker.maximumImagesCount = 4;
    elcPicker.returnsOriginalImage = NO; //Only return the fullScreenImage, not the fullResolutionImage
    elcPicker.imagePickerDelegate = self;
    [self presentViewController:elcPicker animated:YES completion:nil];
}

Answer 1

你应该试试MWPhotoBrowser Control by Michael Waterfall
他提供单一和多张照片选择

适用于iOS 5.1.1+。
所有字符串都是可本地化的，因此可以在支持多种语言的应用程序中使用。

Answer 2

在我的一个项目中，我已经完成了没有ELCImagePickerController的事情。并成功地使用了该代码。在那个项目中，我在图像选择器控制器的导航栏上添加了一个完成按钮。每当您选择一个图像时，您可以使用名为

的方法获取该图像

-(void)imagePickerController:(UIImagePickerController *)pickerdidFinishPickingMediaWithInfo:(NSDictionary *)info

每当你完成拾取图像时，你按下那个完成按钮。在那个方法中解除视图控制器。

使用此过程，您可以选择和获取您想要的图像。

我的应用程序正在成功运作。

...干杯!!!!!!!

在uiimagepickercontroller

的导航栏上添加完成按钮

- (void)navigationController:(UINavigationController *)navigationController
  willShowViewController:(UIViewController *)viewController
                animated:(BOOL)animated
{    
     if (!doneButton) 
    {
        doneButton = [[UIBarButtonItem alloc] initWithTitle:@"Done"
                                                  style:UIBarButtonItemStyleDone
                                                 target:self   action:@selector(saveImagesDone:)];
    }

viewController.navigationItem.rightBarButtonItem = doneButton;
}

首先使用UIImagePickerController显示图像选择器

抓取您的图片

-(void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info
{

    NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];
    if ([mediaType isEqualToString:@"public.image"] 
    {
        UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];


        // Get the data for the image
        NSData* imageData = UIImageJPEGRepresentation(image, 1.0);

        NSArray* paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
        NSString* documentsDirectory = [paths objectAtIndex:0];

        // Now we get the full path to the file
        NSString* fullPathToFile2 = [self createName:documentsDirectory]; 
        // and then we write it out
        [imageData writeToFile:fullPathToFile2 atomically:NO];
}
else
{
    // Show Alert
}

}

关闭图像选择器视图控制器

-(IBAction)saveImagesDone:(id)sender
{
    [self dismissViewControllerAnimated:YES completion:nil];
    [self loadimages]; // Load your Images
}

每次点击图片时

 -(void)imagePickerController:(UIImagePickerController *)pickerdidFinishPickingMediaWithInfo:(NSDictionary *)

info此方法将为您抓取图像。

不要忘记upvote ...干杯...... !!!!!

Answer 4

您需要实施这些方法

- (void)elcImagePickerController:(ELCImagePickerController *)picker didFinishPickingMediaWithInfo:(NSArray *)info;

它将返回您选择的图像数组。（控制器发送回一组结构相似的字典）

- (void)elcImagePickerControllerDidCancel:(ELCImagePickerController *)picker;

Answer 5

试试这个：

- （ID）initImagePicker {

ELCAlbumPickerController *albumPicker = [[ELCAlbumPickerController alloc] initWithStyle:UITableViewStylePlain];

self = [super initWithRootViewController:albumPicker];
if (self) {
    self.maximumImagesCount = 4;
    self.returnsImage = YES;
    self.returnsOriginalImage = YES;
    [albumPicker setParent:self];
    self.mediaTypes = @[(NSString *)kUTTypeImage, (NSString *)kUTTypeMovie];
}
return self;

}

- （id）initWithRootViewController：（UIViewController *）rootViewController {

self = [super initWithRootViewController:rootViewController];
if (self) {
    self.maximumImagesCount = 4;
    self.returnsImage = YES;
}
return self;

}

- （无效）choosePhotoFromExistingImages {

ELCImagePickerController *elcPicker = [[ELCImagePickerController alloc] initImagePicker];  
elcPicker.maximumImagesCount = 4;
elcPicker.returnsOriginalImage = NO; //Only return the fullScreenImage, not the fullResolutionImage
elcPicker.imagePickerDelegate = self;
[self presentViewController:elcPicker animated:YES completion:nil];

}
