问题描述
我需要从iphone图库上传图片,但我没有获得所选图片的路径(使用图片选择器)
i need to upload a image from iphone gallery ,but i am not getting the path of the picked image (using image picker)
在图像选择器委托方法中我正在执行以下操作
in the image picker delegate method i am doing the following
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
[picker dismissModalViewControllerAnimated:YES];
imageView.image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
NSString *strImagePath = [info valueForKey:UIImagePickerControllerReferenceURL];
NSString *strImagePath1 = [info valueForKey:UIImagePickerControllerMediaURL];
NSLog(@"%@",strImagePath);
NSLog(@"%@",strImagePath1);
NSLog(@"%@",info);
}
且信息词典包含以下关键值
and the info dictionary contains following key values
{
UIImagePickerControllerMediaType = "public.image";
UIImagePickerControllerOriginalImage = "<UIImage: 0x16adc0>";
UIImagePickerControllerReferenceURL = "assets-library://asset/asset.PNG?id=1000000153&ext=PNG";
}
我使用密钥UIImagePickerControllerReferenceURL的值作为将其上传到FTP的图像路径但我无法上传文件,可能我所采取的路径不正确。
i used the value for key UIImagePickerControllerReferenceURL as the image path to upload it to FTP but i couldnt upload the file, probably the path which i taking is incorrect.
任何人都可以帮助我如何拍摄所选图像的实际路径使用图像选择器
