问题
I was really impressed, and really grateful about the answers I recived last time I asked here.
I have this problem with Core Plot. I want to have a CPTGraphHostingView inside my UIView so I can have things like labels and scroll views below it.
I am using XCode 3.2 by the way.
How do I do this programmatically? Or with the Interface builder if possible.(I need the instructions to be detailed as im I bit new to this sort of thing) Thanks for your support.
回答1:
If you want to add a core plot graph to a UIView you have to add a CPTGraphHostingView as a subview to the UIView. In the example below, hostingView is a UIView and graphObject is a CPTXYGraph.
CPTGraphHostingView *graphHostingView = [[CPTGraphHostingView alloc] initWithFrame:hostingView.bounds];
[hostingView addSubview:graphHostingView];
graphHostingView.hostedGraph = graphObject;

Simple adding CPTGraphHostingView as a subView of UIView [programatically] didn't work for me.
I have searched through many threads and at the end I tried the simplest way to do this - I have created new UIView in interface builder and in this view I have created another UIView and change it to CPTGraphHostingView. Now I can simply create chart [like in tutorials] and link its main UIView anywhere I want.
I don't know why this didn't work programatically but it works from Interface Builder.
I use Xcode 4.2 and Core plot 1.0
