ios - Place floating UIButton on top of UICollectionView -


i'm desperately trying place uibutton on top of uicollectionview. goal check-in button new foursquare app.

my code looks so:

uibutton *floatingbutton = [[uibutton alloc] init]; [floatingbutton setframe:cgrectmake(320, 150, 50, 50)]; [floatingbutton setbackgroundcolor:[uicolor blackcolor]]; [self.collectionview addsubview:floatingbutton]; [self.collectionview bringsubviewtofront:floatingbutton];

the problem button isn't anywhere.

you want add button collectionview's parent view. self.view, hard sure without seeing more code.

instead of

[self.collectionview addsubview:floatingbutton];

you want

[self.view addsubview:floatingbutton];
