Did you link the WebKit framework to your project? – Chew

Yeah, I'm sure I imported #import <WebKit/WebKit.h>. But the minimum version of Xcode deploy is 7.0. – Upsweep

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? – Chew

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: #25341738 – Chew

@Chew You saved me . 1.I annotated these WKWebView code, that's running ok. – Upsweep

@Chew 2. I added WebKit.framework to the Linked Frameworkds and Libraries, that's ok too. – Upsweep

Finally I checked OS version of the project. Thank you ! @Chew – Upsweep

No Problem. Glad I could help. – Chew

Answer 1

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.
