+ * "Focus the text input with a slight delay to make sure modals are closed first.
  * Since in react-native-modal `onModalHide` is called before the modal is actually hidden.
  * It results in the keyboard being dismissed right away on both iOS and Android.

+ * But the bug already fixed, without using setTimeout for IOS the focus seems to work properly.
+ * Instead there is new IOS bug of text input content doesn't scroll to bottom if using setTimeout,
+ * also there is an android keyboard doesn't show up bug when text input is focused and
+ * the use of setTimeout will make the keyboard show up properly.
