Did you link the WebKit framework to your project? – Jonathan
Yeah, I'm sure I imported #import <WebKit/WebKit.h>. But the minimum version of Xcode deploy is 7.0. – Johnny
I mean, did you: 1. Click on your project in Xcode 2. Select General 3. Locate "Linked Frameworks and Libraries" 4. Click the plus button at the bottom and select "WebKit.framework" 5. Click Add? – Jonathan
If you're minimum deployment target is iOS 7 you'll need to check which version of the OS the device is running. If the user is running iOS 7 you'll have to fall back to UIWebView. If they are using iOS 8 you can use WKWebView. This post will help you: stackoverflow.com/questions/25341238/… – Jonathan
@Jonathan You saved me . 1.I annotated these WKWebView code, that's running ok. – Johnny

Just for reference:

Go to your Project -> General -> Linked Frameworks and Libraries then add WebKit.framework

What you see here is that the WebKit framework is used but the actual binary is not getting linked.
