Recently I tried to implement an all black UISegmentedControl using the tintColor attribute: [segmentedControl setTintColor:[UIColor blackColor]]

I was however not aware that Apple always uses a darker colour to highlight the selected segment. Therefore the above will always stay black. Easy enough to solve: [segmentedControl setTintColor:[UIColor darkGreyColor]]

Took me a while to realise though. Hopefully this saves you some trouble, if you run into the same issue.

While researching (again) the size of the iPhone status bar, I stumbled upon this very useful cheat sheet.

While publishing a temporary iWeb website for a mate of mine, I realised that Google Chrome won’t show the website navigation bar, but instead throws an error to the console saying: “XMLHttpRequest cannot load file://(censored)/feed.xml. Origin null is not allowed by Access-Control-Allow-Origin.”.

What’s the reason for that?
Apparently iWeb is saving the auto-generated navigation to a file called feed.xml and tries to read it via XMLHTTPRequest. When you publish your website with iWeb you enter the final URL for your website. If you are not viewing the website using that particular URL (e.g. your local harddrive), the resource file feed.xml call is considered XSR by your good browser. (e.g. Chrome, Firefox..)

However the really interesting thing is, that Apple’s Safari is loading the resource without even warning the user…

Well done!
