问题 I am trying to implement a "Done" button in a UIPickerView Similar to the one under this link I looked in the class reference but I couldn t find it Thanks 回答1: I added a UIToolbar with a UIBarButtonItem for the 'done' button in my xib with the frame set so that it's not initially visible (y value equal to the height of the parent view). Every time the user access the picker, I changed the frame (the y value) of the UIDatePicker and the UIToolbar with an animation so that it slides up along

Is there a way to remove the authorization prompt from command-line instances of Instruments (XCode)?

No user is ever actually authenticated, even if the correct credentials are granted. I get the following error: Failed to authorize rights (0x20) with status: -60007. 2012-02-27 19:30:37.232 instruments[54151

Autolayout fights with this at runtime. Disabling autolayout completely seems a bit harsh because it could reasonably be used to handle layout for the other views. It seems like what I might want is some kind of "null constraint". Muhammad Aamir Ali I had the same problem. But I have resolved it. Yes, you can disable auto layout at runtime for a specific UIView , instead of

I need to add some rules to my .gitignore file. However, I can't find it in my project folder. Isn't it created automatically by Xcode?
