Is it possible to add something like an UIAlertView to a today widget? I added an IBAction an an UIAlertView to the Widget but nothing happened.
And ist it possible to make a bigger widget? I changed the height in the Size-Inspector but it didn't work at all.
The short answer is no, you cannot show an alert in a today widget. UIAlertControllers are presented modally, and your widget does not have access to the entire screen. It has about 3/4 of the screen height maximum to display in.
