Update OLGhostAlertView.m

[KatkayApps]

Your code was giving warning about deprecation on iOS 7. This solved the problem for me.

Your class is great. I would like to suggest two things to add:

1. a way to change the box vertical position (top, middle and bottom)
2. a way to change the box and text colors.

Beyond that the rest is perfect.

Thanks for the pull request. I'll look into it. Regarding your second post:

1. There's a property called position just for that. Look for it on the readme file.
2. The property style switches between light and dark styles. You can of course just modify the code to draw OLGAV however you like.

ah, sorry about that, I will look at it.

Is there a reason not to use NSString's boundingRectWithSize:options:attributes:context:, as suggested by the compiler warning?

I think it would avoid creating a UILabel just to calculate the rect.

[radutzan]

Because it’s only available in iOS 7 and later. I don't want to break projects targeting earlier versions of iOS.

The label version works with barely all versions of iOS and works wonderfully and also my first version was using NSString's boundingRectWithSize:options:attributes:context: for a iOS 7 project and I discovered this method does not work correctly for some kinds of strings. I ended having wrong sizes all the time. Replacing it with the label method solved the problem.

Yes, but it seems to me that instantiating a label just to get its size may be too much overhead for the task. I'll take a closer look at this issue on the weekend.
