需要加载一个协议 UIImagePickerControllerDelegate

//从手机相册中获得图片并显示在imageView中

- (IBAction)albumClocked:(id)sender {

    //创建一个图片选择器

    UIImagePickerController *imagePicker = [[UIImagePickerController alloc]init];

    //设置选择器的资源类型

    imagePicker.sourceType =UIImagePickerControllerSourceTypeSavedPhotosAlbum;

   

    //设置代理

    imagePicker.delegate = self;

    //采用模态窗口 进行显示

    [self presentViewController:imagePicker animated:YES completion:nil];

}

#pragma mark-imagePickerController方法

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

{

    NSLog(@"%@",info);

    //让模态窗口miss

    [picker dismissViewControllerAnimated:YES completion:nil];

    //在info中通过key找到图片

    self.image = [info objectForKey:UIImagePickerControllerOriginalImage];

    //设置图片

    [self.imageView setImage:self.image];

   

}
