如何获得在iPhone画廊的图像的path

我需要从iPhone画廊上传图像，但我没有得到所选图像的path （使用图像select器 ）

在图像select器委托方法，我正在做下面的事情

- (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); } 

info字典包含以下关键值

 { UIImagePickerControllerMediaType = "public.image"; UIImagePickerControllerOriginalImage = "<UIImage: 0x16adc0>"; UIImagePickerControllerReferenceURL = "assets-library://asset/asset.PNG?id=1000000153&ext=PNG"; } 

我使用的关键UIImagePickerControllerReferenceURL的值作为图像path上传到FTP，但我不能上传文件，可能是我采取的path是不正确的。

任何人都可以帮助我，我怎么能采取图像采集器采摘的图像的实际path

Answer 1

可能会对你有帮助

 [picker dismissModalViewControllerAnimated:YES]; imageView.image= [info objectForKey:@"UIImagePickerControllerOriginalImage"]; NSData *webData = UIImagePNGRepresentation(imageView.image); NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *localFilePath = [documentsDirectory stringByAppendingPathComponent:png]; [webData writeToFile:localFilePath atomically:YES]; NSLog(@"localFilePath.%@",localFilePath); UIImage *image = [UIImage imageWithContentsOfFile:localFilePath]; 

Answer 2

在NSData转换你的图像，然后上传这个NSData 。

你的形象在NSData

 NSData *dataImage = UIImageJPEGRepresentation([info objectForKey:@"UIImagePickerControllerOriginalImage"],1); 

或者你可以使用NSData转换yourImage

 NSData *dataImage = UIImagePNGRepresentation(yourImageView.image);
