Just wanted to chime in to ask anyone interested in using constraints with bars (NavigationBar & Toolbar primarily) to please file bugs with the kinds of things you want to do. > >> I never really understood why that was, it has that ‘NSCell’ code smell >> about it, feels like something done for efficient button bars in iOS 2.0 >> we’ll all suffer for forever. > > The good thing about an abstracted API is that Apple could switch to > one-view-per-bar-button-item tomorrow and none of us would know unless we > looked.

Unfortunately UIToolbar does not call -sizeThatFits: for the views of bar button items. Gerriet, you can try setting the frame of the slider then calling -setNeedsLayout/-layoutIfNeeded on the toolbar to update the layout. If you do this within the standard layout callbacks it should go along with any animation that is already going. > >> >> Can you pin a view over the top of the toolbar using constraints (they are >> both sibling UIViews after all) then pin your slider in there? > > This might work visually, but make sure to get accessibility right. > > --Kyle Sluder > _______________________________________________ > > Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) > > Please do not post admin requests or moderator comments to the list. > Contact the moderators at cocoa-dev-admins(at)lists.apple.com > > Help/Unsubscribe/Update your Subscription: > https://lists.apple.com/mailman/options/cocoa-dev/david.duncan%40apple.com > > This email sent to david.dun...@apple.com -- David Duncan _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
