IOS 7 simulator against differences in devices?

The basic deployment of the application is iOS 7.0, and both devices and the simulator use 7.0.

The translucent effect on the simulator gives blurring of the content under the UINavigationBar , but it does not blur on the device. I noticed a couple of other difference tools. My UIToolbar was transparent on the simulator, but opaque on the device, and there were several times when the colors did not match.

For the navigation bar though, why is this different and how can I get the blur effect? Without blur, the text in the text of the navigation bar can be distracting and confusing!

After multiple digging, this is a hardware limitation. Blur effect is not enabled on older devices due to GPU requirements / performance.

The blur effect will appear on:

  • iPhone 4S and later
  • 4th generation iPad and later
  • all iPad Mini
