NOTE: About array and map

React Native doesn't provide any guarantees about the types of values in these structures. Your native module might expect array of strings, but if JavaScript calls your method with an array that contains number and string you'll get NSArray with NSNumber and NSString. It's developer's responsibility to check array/map values types (see RCTConvert for helper methods).

Callbacks #

WARNING

This section is even more experimental than others, we don't have a set of best practices around callbacks yet.

Native module also supports a special kind of argument - callback. In most cases it is used to provide function call result to JavaScript.

Troubleshooting

Cmd-R does not reload the simulator #

Enable iOS simulator's "Connect hardware keyboard" from menu Hardware > Keyboard menu.

Keyboard Menu

If you are using a non-QWERTY/AZERTY keyboard layout you can use the Hardware > Shake Gesture to bring up the dev menu and click "Refresh"

Port already in use red-screen #

red-screen

Something is probably already running on port 8081. You can either kill it or try to change which port the packager is listening to.

Kill process on port 8081 #

$ sudo lsof -n -i4TCP:8081 | grep LISTEN

then

$ kill -9 <cma process id>

Change the port in Xcode #

Edit AppDelegate.m to use a different port.

// OPTION 1 + // Load from development server. Start the server from the repository root: + // + // $ npm start + // + // To run on device, change `localhost` to the IP address of your computer, and make sure your computer and + // iOS device are on the same Wi-Fi network. + jsCodeLocation = [NSURL URLWithString:@"http://localhost:9381/index.ios.bundle"];
