Hi All,
I decided I would try and play with the new WebKit, and following the
docs I tried to get a web page to display, but I get the warning when I
compile that:
main.m:93: warning: `WebFrame' does not respond to `loadRequest:'
The docs don't agree with the compiler. Nothing happens when I try to
load the page though. Here is my code in case it is of use to figure
this strange behavior out. (I modified Tiny.m, from "Cocoa
Applications" for my purposes.)
Any ideas?
