无法使用模拟器从 ios 中的 ImagePicker 获取图像路径和图像？

Question

我正在尝试从 imagepicker 获取图像路径和选定图像 controller.I 已使用委托方法获取路径和图像，但我总是得到 null。

显示图片选择器的代码

- (IBAction)choosePicture:(id)sender
{
    UIImagePickerController *pickerController = [[UIImagePickerController alloc]
                                                 init];
    pickerController.delegate = self;
    [self presentViewController:pickerController animated:YES completion:nil];


}

委托代码

- (void) imagePickerController:(UIImagePickerController *)picker
         didFinishPickingImage:(UIImage *)image
                   editingInfo:(NSDictionary *)editingInfo
{

    //You can retrieve the actual UIImage
    UIImage *pick_image = [editingInfo valueForKey:UIImagePickerControllerOriginalImage];

    NSURL *path = [editingInfo valueForKey:UIImagePickerControllerReferenceURL];
    [picker dismissViewControllerAnimated:YES completion:^{
    }];
}

视图控制器的协议代码

#import <UIKit/UIKit.h>

@interface RegisterViewController : UIViewController <UIImagePickerControllerDelegate, UINavigationControllerDelegate>
@property (weak, nonatomic) IBOutlet UITextField *txt_fname;
@property (weak, nonatomic) IBOutlet UITextField *txt_lname;
@property (weak, nonatomic) IBOutlet UITextField *txt_profession;
@property (weak, nonatomic) IBOutlet UITextField *txt_language;
@property (weak, nonatomic) IBOutlet UITextField *txt_email;
@property (weak, nonatomic) IBOutlet UITextField *txt_password;
@property (weak, nonatomic) IBOutlet UITextField *txt_confirm_password;
@property (weak, nonatomic) IBOutlet UITextField *txt_profile;
@property (weak, nonatomic) IBOutlet UITextField *txt_address;

@end

Answer 1

也许使用 - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info;

更好

喜欢

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    UIImage *originalImage = info[UIImagePickerControllerOriginalImage];
}

Answer 2

使用这个委托方法

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

以下一项已弃用（您使用过）

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo NS_DEPRECATED_IOS(2_0, 3_0);

Answer 3

请使用 [editingInfo valueForKey:UIImagePickerControllerMediaURL] 而不是 [editingInfo valueForKey:UIImagePickerControllerReferenceURL]; 这将为您提供图像的路径。
