Less Blur with `Visual Effect View with Blur`?

Title pretty much asks it all... I'm playing with the iOS8 Visual Effect View with Blur . It's over a UIImageView that shows a user choosable background photo. The view placed in the contentView itself is my own custom view, shows a sort of graph/calendar. Most of said calendar graph is transparent.

But Apple only seems to give three canned values: typedef enum { UIBlurEffectStyleExtraLight, UIBlurEffectStyleLight, UIBlurEffectStyleDark } UIBlurEffectStyle; I've monkied around with

问题 My app uses UIBlurEffect , however older devices (specifically iPads 2 and 3, that support iOS 8) don't have blur support. I'd like to check if the user's device has blur support or not. How do I do it? 回答1: UIDevice has an internal method [UIDevice _graphicsQuality] that seems promising, but of course your app will be rejected by Apple. Let's create our own method: First of all, we need to know the exact device type we're working on: #import <sys/utsname.h> NSString* deviceName() { struct
