The only iOS app I can recall that integrates with 1Password is HipChat. Integration requires using AgileBits' extension (https://github.com/AgileBits/onepassword-app-extension). The password manager doesn't have any OS-level hooks that allow it to work with any app.

This is no longer true in iOS 11 (and may have been true in iOS 10). Programs may opt into showing “secure” share extensions in the same way that has been in Safari since share extensions were introduced.

I've been using bitwarden for a few months now, and it has totally supplanted LastPass in my workflow.
The only thing I miss is LastPass's form fill capability, but so far that's not been a huge barrier; trusting my browser to keep my credit card and address information handy and relatively safe isn't as convenient, but it's acceptable.
