多图像选择器objective-c

Question

在我的应用程序中，我希望该用户应该能够从他的图库中选择多个图像，但使用UIImagePickerController我们一次只能选择一个图像。 因为我是一个新鲜的，并没有太多的Objective-C的知识，我不能实现GitHub上可用的多图像选择器组件，如MAImagePicker，QBImagePicker，ELCImagePickerController。

如果有人使用过这些组件中的任何一个，请向我提供示例代码和实现该代码的步骤。

Answer 1

使用ELCImagePicker https://github.com/B-Sides/ELCImagePickerController

从项目的GitHub和进口下载。

加选择图像按钮

- (IBAction)selectImg:(id)sender 
{ 
    ELCImagePickerController *elcPicker = [[ELCImagePickerController alloc] initImagePicker]; 
    elcPicker.maximumImagesCount = 100; //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]; 
} 

获得图片来自此方法。

- (void)elcImagePickerController:(ELCImagePickerController *)picker didFinishPickingMediaWithInfo:(NSArray *)info 
{ 
    [self dismissViewControllerAnimated:YES completion:nil]; 

    for (NSDictionary *dict in info) 
    { 
     if ([dict objectForKey:UIImagePickerControllerMediaType] == ALAssetTypePhoto) 
     { 
      if ([dict objectForKey:UIImagePickerControllerOriginalImage]) 
      { 
       UIImage* image=[dict objectForKey:UIImagePickerControllerOriginalImage]; 
       [arrImgs addObject:image]; 
      } 
     } 
    } 

} 

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