TLDR: How do I call standard floating point code in a way that compiles both 32 and 64 bit CGFloats without warnings?
I was trying to add some CGFloat values recursively in my program. And I just realized in one particular scenario the total generated was incorrect. To ensure I had nothing wrong开发者_如何学运维 in m
I need to create a CGSize to compute text height of an arbitrary text with arbitrary length. UIKit has this nice method -siz开发者_JS百科eWithFont:constrainedToSize: and my text is only constrained in

Anyone see the issue here? double lat开发者_如何学CDouble = [latString doubleValue]; double lngDouble = [lngString doubleValue];
Can someone expl开发者_开发知识库ain why this causes the error stated in the title? CGFloat dx = fabs(lastPoint.x - currentPoint.x);
I\'ve got some internal codes for colors in my application, so I created a function that, given a color, returns the code. I\'m having problems as it just doesn\'t work and return always \"01\" for ev
In my iPhone app, I have a appSettings.plist. This allows me, but also others to simply change some parameters. One of the parameters is the predominant color of the app. The .plist looks like this:
[I might be misunderstanding this entire topic, as I\'ve grown up with languages that allow the dev to almost entirely ignore processor architecture, like Java, except in some particular cases. Please
First post here. Having a problem with NSNumber\'s floatValue method -- somehow, it returns an imprecise number.Here\'s the problem:I store a bunch of NSNumbers in an array, like this:
