类似微信选照片（根据需要进行了修改）

用法：在使用时添加 #import "DNImagePickerController.h"

pragma mark - 选择图片的方法

• (void)buttonAction:(id)sender { DNImagePickerController *imagePicker = [[DNImagePickerController alloc] init]; imagePicker.imagePickerDelegate = self; [self presentViewController:imagePicker animated:YES completion:nil]; }

pragma mark - DNImagePickerControllerDelegate----返回的代理。

• (void)dnImagePickerController:(DNImagePickerController *)imagePickerController sendImages:(NSArray *)imageAssets isFullImage:(BOOL)fullImage imageArray:(NSArray *)imageArray { NSLog(@"imageArray======%@ /n fullImage===%d",imageArray,fullImage); }

• (void)dnImagePickerControllerDidCancel:(DNImagePickerController *)imagePicker { [imagePicker dismissViewControllerAnimated:YES completion:^{

  }]; }
