Blur the background in iOS

Prerequisites

• A working iOS quickstart
• Background effects enabled for the project

Enable blur

NosmaiBackgroundSegmentationConfig *config =
    [[NosmaiBackgroundSegmentationConfig alloc] init];
config.mode = NosmaiBackgroundSegmentationModeBlur;
config.blurStrength = 50.0f;

[[NosmaiCore shared].effects setBackgroundSegmentation:config];

blurStrength uses 0 through 100. Apply an updated configuration when the user changes the slider.

Disable blur

[[NosmaiCore shared].effects clearBackgroundSegmentation];

Verify it worked

The subject should stay sharp while the scene behind it becomes blurred.
