Question

我在cocos2D开发了我的应用程序。

我使用了自定义UIView，其中包含2 UITextField和1 UITextView，并且还具有获取照片的功能。

在我的应用程序中，我使用UIImagePickerController从相机/库中拍摄图像。所有功能都正常工作，但是当我从相机/图书馆选择照片然后解雇我的imagePicker后，我无法再次在UITextField中输入文字。

我也看这个Question，然后关注它们。

我的相关代码是：

#pragma Mark -
#pragma Mark - ActionSheet Delegate Methods

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{

    UIImagePickerController *imgPicker=[[UIImagePickerController alloc] init];
    imgPicker.delegate=self;
    imgPicker.wantsFullScreenLayout = YES;
    imgPicker.allowsEditing=YES;

    if(buttonIndex == 0)
    {
        isVideoTakenFromCamera = YES;
        if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
            imgPicker.sourceType = UIImagePickerControllerSourceTypeCamera;
        else
            imgPicker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
    }
    else if (buttonIndex==1)
    {
        isVideoTakenFromCamera = NO;
        imgPicker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
    }


    [[XPSModal sharedInstance] hideWindow]; // it is my custom UIView.
    [[CCDirector sharedDirector] presentViewController:imgPicker animated:YES completion:nil];
   // [[[[UIApplication sharedApplication] delegate] window] makeKeyWindow]; i alsos put here this code but it is not works for me.
}

#pragma mark -
#pragma mark - UIImagePickerController Delegate Method

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

   UIImage *img = [info objectForKey:UIImagePickerControllerEditedImage];
   img = [self resizeImage:img];
   [self.btnTakePhoto setImage:img forState:UIControlStateNormal];

   [[CCDirector sharedDirector] dismissViewControllerAnimated:YES completion:nil];
   [[XPSModal sharedInstance] showWindow]; // it is my custom UIView.
   [[[[UIApplication sharedApplication] delegate] window] makeKeyWindow];
}

从库/相机中选择照片时会出现问题。其他智能键盘工作正常。

使用此代码

Declare this `UIImagePickerController  *imagePicker;`  as a global then follow this code..




-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex

    {

        if(buttonIndex==1)
        {
            imagePicker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
            [self presentModalViewController:imagePicker animated:YES];
        } else if(buttonIndex==2) {
            if ( [UIImagePickerController isCameraDeviceAvailable:UIImagePickerControllerCameraDeviceFront] || [UIImagePickerController isCameraDeviceAvailable:UIImagePickerControllerCameraDeviceRear]) {
                imagePicker.delegate = self;
                imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
                [self presentModalViewController:imagePicker animated:YES];

            }

        }


    }
    - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
        [imagePicker dismissModalViewControllerAnimated:YES];
        _profilePicImgView.image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
        if (picker.sourceType == UIImagePickerControllerSourceTypeCamera) {
            UIImageWriteToSavedPhotosAlbum(_profilePicImgView.image, nil, nil, nil);
        }
    }

UIImagePickerController被解除后无法通过键盘输入文本。
