iOS frosted glass effect

Method One: Support all iOS system versions:

-(void) Setupblurview

{

Uiimageview *darkview = [[Uiimageview alloc] init];

Darkview.frame = Self.view.bounds;

UIImage *image = [UIImage imagewithdata:_hotmodel.picdata];

Darkview.image = image;

Darkview.backgroundcolor = [Uicolor Clearcolor];

[Self.view Addsubview:darkview];

_darkview = Darkview;

Uitoolbar *toolbar = [[Uitoolbar alloc] init];

[ToolBar Setbarstyle:uibarstyleblack];

[Darkview Addsubview:toolbar];

Toolbar.translatesautoresizingmaskintoconstraints = NO;

[ToolBar mas_makeconstraints:^ (Masconstraintmaker *make) {

Make.edges.equalTo (Darkview);

}];

}

Method Two: Only in the ios8.0 above has the effect, using the system's API implementation

-(void) addeffectview{

Uiimageview *darkview = [[Uiimageview alloc] init];

Darkview.frame = Self.view.bounds;

UIImage *image = [UIImage imagewithdata:_hotmodel.picdata];

Darkview.image = image;

Darkview.backgroundcolor = [Uicolor Clearcolor];

[Self.view Addsubview:darkview];

_darkview = Darkview;

Uiblureffect *dark = [Uiblureffect Effectwithstyle:uiblureffectstyledark];

Uivisualeffectview *effectview = [[Uivisualeffectview alloc] initwitheffect:dark];

Effectview.frame = Self.view.bounds;

[Darkview Addsubview:effectview];

}
