uialertview

问题 I have written my custom UIAlertview to allow auto dismissal in certain cases. Now, with iOS 7 when auto dismissal happens the tint color of my nav bar changes.

P.S.: Finally I found control , which allows that: https://github.com/eaigner/CODialog 回答1: Can you suggest something I can use instead?

Animation is not smooth). I didn't added any logic for coding just created the UI. I didn

问题 I am subclassing a UIButton and detecting finger movements, if the user swipes his finger in a certain way I will pop up an UIAlerView. All good, except that after dismissing the UIAlertView... when the user next touches the UIButton the button goes to it's highlighted state and gets stuck there, continuously highlighted, even when no finger touching it. Pressing the button again the UIButton begins to behave normally (only highlights when touched). So I can only presume that an alert during

问题 If a UIAlertView contains a certain amount of text, the text display is automatically changed to have scrollbars. I would like this text to be centre-aligned. Searching around for the solution provides this SO response. However, this does not work on a UIAlertView that contains scrollbars.
