Problem with infoButton on Utility based app

BenODwyer · 02-11-2009, 05:36 AM

Hi Guys

I am having an issue with the info button in a stardard xcode utility based app.

All I have done is put a button in the middle of the MainView.xib and now when I run the app the infoButton to flip the view only works if you tap it about 3 or 4 times.

If I remove the button and have my MainView blank it is fine.

Has anyone else had this problem?

Does anyone know something obvious I am doing wrong.

Thanks in advance.

You're doing nothing wrong, it's that the info button is so tiny, it's hard to hit. One way around this is to make a larger invisible custom button (don't select a background) and have it connect to the same method as the info button. Now drag the info button to the center of the invisible button.

You can also make the info button's frame bigger. Then you still get the info button animation.

I set the invisible button to "glow," but how do you make the info frame bigger?

It's just a UIView ultimately. Any view can have it's frame set. I do it in code though. I don't use IB.

I'm not at that level yet

Thanks guys. Looks like I am going to have to place the infobutton programatically rather than in IB.

Cheers for the pointers it has been driving me nuts!

Is it really true that IB doesn't allow you to change the size of a button?

Round rec or custom buttons can be changed easily.

Yes I tried putting a custom blank button over the top and calling the toggleView. But it didn't improve the performance at all.

I will do a re-write tomorrow after giving it a bit of brain time. I do tend to rely on IB quite alot.

Works great here Ben.

Hmm... Interesting.

Are you just linking the touchDown or TouchUpInside of the new button to the toggleView in the First Responder ?

If I make a new project of type Utility App it seems to respond fine. But as soon as I put anything in MainView.xib e.g. a button it starts to only respond to every third or fourth press.

Very frustrating...

I just had the same problem and found a page with great sample code showing how to make the infoButton frame larger: iPhone SDK Examples
I am using XCode's "Utility Application" project template and so I stuck the code in viewDidLoad in RootViewController.m--could be the wrong place for all I know (I'm just starting out to develop on the iPhone) but it did seem to work, making the infoButton much easier to tap.

Very useful! Thanks for posting.

Can anyone confirm this? I have added a button Type: Info Light via interface builder. I tried using the code to increase the frame size, but can't tell any difference when I run it.

Is it required to add the button programatically in order to change the frame size? I do know that if I look at the size in Interface Builder, the values 18 x 19 are grayed out.
