How to set selected segment index in UISegmentedControl?
(2 answers)
Closed 7 years ago.
I've connected a UISegmentedControl outlet. In my viewDidLoad() I check some stuff out to determine if I need to jump to the third index of the UISegmentedControl but I had no luck.
I made this:
self.mainSelector.isEnabledForSegmentAtIndex(2)
Of course it did't work. What should I do to jump automatically to the third segment?
The selected segment in a UISegmentedControl is determined by its selectedSegmentIndex.

I have a screen in my app that contains a TextField.
I want the keyboard for the TextField to be displayed on default (i.e. as soon as the user navigates to the view, the keyboard should already be up).
How is this accomplished?
You have to just make an outlet from textfield and follow the following code.

How to show popup "copy" when select cell of table ?
You can't do it the normal way with UILabel. If you still want to do it, use UITextField instead and disable editing (It will act as label and allow text selection). If you want to use UILabel anyways, you might want to look into UILongGestureRecognizer and UIPasteBoard. Add gesture to the label and on its delegate method, copy text to paste board.

There's a nice example over there... I'm sure no one will have the time to "spin" it all the way to MaxInteger :)
