If you want to click and hold text using the Text component, this feature does not currently exist in React Native for iOS. You probably want to add https://react-native.canny.io/feature-requests/p/support-selecting-text-within-text-elements-for-copypaste-etc to offer Facebook add support for this.
However, I introduced support for Android starting with React 0.30. But React iOS draws characters directly on the screen (and does not use its own UITextView, which supports the selected property), so it is not supported there and probably will not be for a long time.
RN 0.39 adds support for copying the entire text field, but does not yet include support for selecting a subset of the text field to copy.
