The other week I compiled a calculator to determine what bar tint color to set a UINavigationBar to if you want the blur effect on iOS 7. This works well, but only if your RGB values are >= 102 – because Apple adjusts the RGB you set the bar to.
Lately I’ve been experimenting with darker colors, those with RGB values under 102. There is a work around, however it requires some tricks.
One of the new effects in iOS7 is blurred content. At WWDC this year they were showing off how to do this with snapshots and image filtering. The downside to that is that it’s a static image and wont change with the content behind the view.
Back when I owned an iPhone 3GS I often noticed many blurry looking apps, some from small developers and some from Apple themselves (check out the Sales + Updates UISegmentedControl in the iTunes Connect app on an iPhone 3G/3GS). It wasn’t until I started noticing it in my apps that I realised exactly what the problem was. It’s caused by a UIView having it’s origin or size values containing a decimal place. For example if the origin of a view was ‘5’ then it would look crisp, but if it was shifted to ‘5.5’ then it would be blurred to make it seem half way between 5 and 6 because there’s not enough pixels to actually do this. If you are testing on the iPhone 4 then you will miss this as it has enough pixels to actually have a view sit between between the two points. The most common cause for this is setting the view’s center position.
