How to fix “No unexpired provisioning profiles found that contain any of the keychain’s signing certificates” in Xcode 4

Since Xcode 5 and iOS 7 the default appearance of a UINavigationBar is black translucent. This even affects the same app running in iOS 6. Black opaque is deprecated and can no longer be set in Interface Builder. However, you can set the appearance for all nav bars by putting this little gem in your App Delegate’s didFinishLaunchingWithOptions method: [[UINavigationBar appearance] setTintColor:[UIColor blackColor]]; You can specify colours other than black.

How to remove a widget from the WordPress Dashboard permanently
If you want to never see a widget on your WordPress Dashboard ever again, just head over to the top where it says “Screen Option”, then simply un-tick the ones you don’t like.

How to define Javascript Behaviours in Dreamweaver
Dreamweaver keeps on giving – and the more I’m looking into it, the more I like how it can support me. Today I discovered that you can define Javascript Behaviours without writing a single line of code.
