当尝试从inappbrowser打开Cordova IOS相机插件不工作 [英] Cordova IOS camera plugin not working when trying to open from inappbrowser

问题描述

我正在使用cordova 6.0.0的混合移动应用程序。

根据我的要求，我必须在网络视图中打开动态网址。 url将由api响应提供。

我在应用程式浏览器外挂程式中使用cordova应用程式浏览器。

https://github.com/apache/cordova-plugin-inappbrowser

现在，当用户点击在Web视图中打开的页面中的任何链接时，我必须捕获该点击事件，并找到用户点击的锚标记的href值。

如果目标网址匹配我的条件，我必须打开相机，而不关闭网页视图，这样，即使在拍摄照片后，我可以保持网络视图的状态成功。

对于相机功能，我使用cordova默认的相机插件。

/ p>

但是在IOS的情况下，我不能打开相机。因为我已经检查控件是在相机插件内，但它是在下面警告

 警告：尝试呈现< CDVCameraPicker：0x1570d1800> On< MainViewController：0x1565624a0>其视图不在窗口层次结构中！ 
 

我已经检查过很多与此相关的帖子，有些人建议使用Iframe而不是网络视图。但是我无法捕获动态加载的iframe中的点击事件。

有人可以帮助我应该是什么解决方案，是有任何方式，我可以做到

提前感谢

解决方案

有同样的问题，设法解决它。您必须打开InaAppBrowser作为一个子视图显示摄像机在它的顶部。所有修改发生在CDVInAppBrowser.m中，如果InAppBrowser插件。

您必须修改CDVInAppBrowser的show方法：

  dispatch_async（dispatch_get_main_queue（），^ {
 if（weakSelf.inAppBrowserViewController！= nil）{
 //[weakSelf.viewController presentViewController：nav animated： YES completion：nil]; 
 self.inAppBrowserViewController.view.frame = CGRectMake（0,20，self.inAppBrowserViewController.view.frame.size.width，self.inAppBrowserViewController.view.frame.size.height-20） ; 
 [self.viewController.view addSubview：self.inAppBrowserViewController.view]; 
} 
}）; 
  

只需删除已注释的行并添加注释行后的2。在CDVInAppBrowser的close方法中，您必须添加：

  UIView * lastView; 
 for（UIView * subview in [self.viewController.view subviews]）{
 lastView = subview; 
} 
 [lastView removeFromSuperview]; 
  

正在 [self.inAppBrowserViewController close]; 。

完成后，相机现在会在inappbrowser的顶部打开，并将图像传递给它。

ps：记住删除并添加ios平台以应用更改

I am working for a hybrid mobile app using cordova 6.0.0.

According to my requirements , I have to open dynamic url in web view. The url would be provided by api response.

I am using the cordova in app browser plugin for web view.

https://github.com/apache/cordova-plugin-inappbrowser

Now when user clicks on any link in the page opened in the web view , I have to catch that click event and find the href value of the anchor tag on which user had clicked.

And if target url will match my condition , i have to open camera without closing the web view , so that i can maintain the state of web view even after picture was taken successfully.

For camera functionality i am using cordova default camera plugin.

I have done this successfully in Android.

But in case of IOS i am not able to open camera. As i have checked the control is going inside the camera plugin , but it is giving below warning

Warning: Attempt to present <CDVCameraPicker: 0x1570d1800> on <MainViewController: 0x1565624a0> whose view is not in the window hierarchy!

I have checked many posts regarding this and some peoples have suggested to use Iframe instead of web view. But i am not able to catch the click event in dynamically loaded Iframe.

Can someone please help what should be the solution for this , is there any way i can do this as per my requirements.

Thanks in advance

I recently had the same problem and managed to solve it. You have to open the InaAppBrowser as a subview to show the camera on top of it. All modifications take place in the CDVInAppBrowser.m if the InAppBrowser plugin.

You have to modify the show method of CDVInAppBrowser:

dispatch_async(dispatch_get_main_queue(), ^{
    if (weakSelf.inAppBrowserViewController != nil) {
        //[weakSelf.viewController presentViewController:nav animated:YES completion:nil];
        self.inAppBrowserViewController.view.frame = CGRectMake(0,20,self.inAppBrowserViewController.view.frame.size.width,self.inAppBrowserViewController.view.frame.size.height-20);            
        [self.viewController.view addSubview:self.inAppBrowserViewController.view];
    }
});

Just remove the commented line and add the 2 following the commented line. In the close method of CDVInAppBrowser you have to add:

UIView *lastView;
for(UIView *subview in [self.viewController.view subviews]) {
    lastView = subview;
}
[lastView removeFromSuperview];

right before [self.inAppBrowserViewController close];.
Done, the camera now opens on top of the inappbrowser and passes the image to it.

p.s.: remember to remove and add the ios platform in order to apply the changes
