On iOS 9+, add `wechat` and `weixin` into `LSApplicationQueriesSchemes` in
`Targets` > `info` > `Custom iOS Target Properties`. Or edit `Info.plist`
then add:
```xml
LSApplicationQueriesSchemes
weixin
wechat
```
Then copy the following in `AppDelegate.m`:
```objc
#import
// ios 8.x or older
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
return [RCTLinkingManager application:application openURL:url
sourceApplication:sourceApplication annotation:annotation];
}
// ios 9.0+
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url
options:(NSDictionary *)options
{
return [RCTLinkingManager application:application openURL:url options:options];
}
```
