There are many ways to create the settings object
_UIBackdropViewSettings *settings = (_UIBackdropViewSettings *)[[[_UIBackdropViewSettingsSemiLight alloc] init] autorelease];
_UIBackdropViewSettings *settings = [_UIBackdropViewSettings settingsForStyle:2070];
_UIBackdropViewSettings *settings = [_UIBackdropViewSettings settingsForPrivateStyle:2070];
_UIBackdropViewSettings *settings = [[[_UIBackdropViewSettings alloc] initWithDefaultsValue] autorelease];
Creating _UIBackdropView (Blur view) object
// Creating blur view using settings object
_UIBackdropViewSettings *settings = [_UIBackdropViewSettings settingsForStyle:2060];
// initialization of the blur view
_UIBackdropView *blurView = [[_UIBackdropView alloc] initWithFrame:CGRectZero
autosizesToFitSuperview:YES settings:settings];
// another way for initialization
_UIBackdropView *blurView = [[_UIBackdropView alloc] initWithSettings:settings];
// or without settings object implementation
_UIBackdropView *blurView = [[_UIBackdropView alloc] initWithStyle:2060];
[someView addSubview:backView];
[blurView release];
Blur Quality
There are only two qualities available.
- low
- default (Assumed to be "medium")
You can set it like this:
[blurView setBlurQuality:@"low"];
Tinting blur view
[blurView setRequiresColorStatistics:YES];
[blurView setUsesColorTintView:YES];
[blurView setColorTint:[UIColor cyanColor]];
[blurView setColorTintAlpha:0.8];
[blurView setColorTintMaskAlpha:0.7];
Applying blur settings
You can config the settings parameter then apply and update the blur view.
_UIBackdropViewSettings *newSettings = [_UIBackdropView settingsForPrivateStyle:0];
// Whatever configuration for the settings
[blurView applySettings:newSettings];
// or
[blueView computeAndApplySettings:newSettings];
Getting/Parsing all _UIBackdropView objects at runtime
NSArray *blurViews = [_UIBackdropView allBackdropViews];
for (_UIBackdropView *view in blurViews) {
// do any _UIBackdropView configuration here
}
