如何获取iphone库中的图像路径 [英] how to get the path of the image which is in iphone gallery

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

推荐答案

可能对你有帮助

[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];
