问题 I followed the Readme from react-native-image-picker with both manual and automatic linking (tried both separately). When I launch simulator from terminal using react-native run-ios I get the error. When launching from Xcode it works fine, I can access the CameraRoll picker no problem. Here are the versions I'm using: "react-native": "0.43.3", "react-native-image-picker": "^0.26.3", I saw a similar thread here stackoverflow and it seems I'm not the only one having this issue. Thank you for

问题 We are having a problem with React Native Fetch Blob when a PDF is over 1mb in size. The file is being uploaded to Azure Blob Storage and works fine when the PDF is less than 1MB but as soon as the file is over 1MB the upload fails and the file in the container is empty. We are using the module in an IOS React App but we also have a web app. When we upload the PDF via the web app everything is fine so it seems that this is something specific to the mobile app. Further testing shows that if we

问题 Hello World, I trying to crop an image like explain on the React-native Doc <Image source={{uri: this.props.image, crop: {left: 50, top: 50, width: 100, height: 100}}} style={{height: 100, width: 100}}/> But it's doesn't work the image is not cropped.

问题 The below code does not work properly in iOS (iPhone 6). When I press ‘Push Me’, the word is not displayed completely and the cursor is also not shown. On further investigation, I found out that onChangeText and onContentSize change are not triggered. Pressing any key on the key board after pressing the ‘Push Me’ button displays the full word. I want the full word to be displayed when the button is clicked. It works, if I use value prop to update the TextInput. But I need to display formatted

问题 As described in this issue, we can't implement a gRPC client using the Node implementation because " RN is not pure Node ". So I started working on an Objective-C implementation using the Native Modules. [service postWithRequest:request handler:^(RequestConfirmation * _Nullable response, NSError * _Nullable error) { if (response) { // This prints correctly in my JS console RCTLogInfo(@"%@", response.message); // This generates an error, see below resolve(response); // This works NSDictionary

问题 Description I need to write an e2e test that in some point it has to select an image in UIImagePickerController, I tried to use element(by.type('UIImagePickerController')). tapAtPoint() with no use. I need a way to select an image. I have found a way to do it with native tests. Also mocking isn't an option for me since I use a higher version that the one react-native-repackeger needs.

问题 I need to implement AutoCompleteTextView in react native. The problem is that there is no such built-in component. All the modules and libraries available to mimic this feature is not completely similar. The main issue is the suggestions are not appearing over the view(like that of select box/picker). Even if it is then it is not behaving perfectly withKeyboardAvoidingView. The whole point is it is not working like native AutoCompleteTextView for Android The other solution is using native UI

问题 I am using react-native-notification module to send a local notification when I receive a socket.io event sent from the server. The notification is properly configured and works on both iOS and Android in foreground mode. However, due to the fact that Apple doesn't allow Apps to run on the background except for (Audio, navigation map, etc.), I am not able to receive any socket events when my app is not on the background and temporarily suspended. I'm therefore not able to send a local
