如何在iOS中从图库中获取图像路径

Question

我想使用Objective-C

为iPhone图库使用didFinishPickingMediaWithInfo获取图像路径

Answer 1

您可以在 didFinishPickingMediaWithInfo 方法中从信息 dic获取​​所有图像信息。您可以使用 UIImagePickerControllerReferenceURL 作为所选图像的referenceURL。

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
             NSLog(@"Image Dic Description :%@",info.description);
}

你从它下面得到钥匙：

UIImagePickerControllerCropRect
UIImagePickerControllerEditedImage
UIImagePickerControllerMediaType
UIImagePickerControllerOriginalImage
UIImagePickerControllerReferenceURL 

Answer 2

您必须创建路径并将该图像写入应用程序文档文件夹中。

NSString * imageName = [NSString stringWithformat:@"sample_img.png"]; // Imgae name
NSArray* paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString* documentsDirectory = [paths objectAtIndex:0];
NSString* pathToFile = [documentsDirectory stringByAppendingPathComponent:imageName];
NSLog(@"Image Path=%@",pathToFile);    //This will print the path in console
[imageData writeToFile:fullPathToFile atomically:NO];
