I'm working through the XSViewController example project from KATIDev and I came across this line:[(ColorView*)[self view] setBackgroundColor:[[NSColor greenColor] colorWithAlphaComponent:.5]];and realized I don't understand (ColorView*). It looks like it's declaring a pointer to an object, but it's followed by a method. Could somebody tell me the name of the function (ColorView*) is performing so I can look it up and figure it out?
There is no function.It is declaring that the result of the [self view] sub-expression should be treated as a pointer to a ColorView by the compiler.
Nothing more, nothing less.It is just a typecast to likely suppress a compiler warning because whoever defined -view likely defined it as returning a reference to an NSView, which does not respond to -setBackgroundColor:
