Proxy settings in UIWebview or at application level
Hi, I am currently working on making an iOS browser which will have provision to set proxy in it. I am making browser as wrapper around UIWebview. But as NSURL / NSREQUEST doesn't support setting proxy, so I got struck here. I know that we can set proxy in CFURL, so is there any way we can capture packets send by UIWebview at CFNetwork level inside our application to route them through proxy server? Or does Cocoa supports reflection to set proxy dynamically inside application sandbox? Any other way by which we can set proxy in UIWebview or at application level? Please help. -- Thanks, Vikas Mahajan P.S.: I don't want to use ASIHTTPRequest because it has a lot of limitations, so please suggest some different method. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Simple question - Subclassing NSView
Hi,
I have recently started programming on Mac using Objective-C and Cocoa. I am
coming from C++/C# world. So, its a fairly basic question. Please help me
understand the following code:
@implementation MyView /*MyView inherits from NSView */
-(void)drawRect: (NSRect)aRect {
[[NSColor blackColor] set];
NSRectFill( [self bounds] );
}
In first line, I was expecting something like [self setColor:[NSColor
blackColor]]; (similar to this.color = NSColor.blackColor; in C#/C++)
how NSColor object knows about where to set the color?
In second line, NSRectFill(), I was expecting it to be called using square
bracket [] notation. Again how this function knows where to fill the rectangle?
There is no reference of NSView passed into the function?
Lastly what are the rules of using () verses []?
Thanks in advance for your time!

Re: Simple question - Subclassing NSView
O'kay, that was helpful.
I still have one doubt. The declaration of NSRectFill is as below:
void NSRectFill (
NSRect aRect
);
NSRectFill() is a C function, not part of any class e.g. NSView. aRect is
simply a struct which specify location points (doesnt contain reference of any
window). How the function knows about the drawing surface, in which
window/surface to paint? Does it implicitly make use of some self pointer? If
so, then, what if this function is not called from inside a simple C function
then there will not be any self pointer?
Thank You,

It's not setting the color of the NSView, it's setting the color of
the pen used by subsequent drawing operations such as NSRectFill().
In second line, NSRectFill(), I was expecting it to be called using square

The NSView reference is self, as the code is implementing a method
of an NSView subclass. NSRectFill is a C function, not an Objective-C
method; you can mix C and Objective-C freely in a .m file.
Lastly what are the rules of using () verses []?
If you want to call a plain C function, use the function name plus
parentheses just as you would in a plain C program. If you want to
call a method on an object, use the square bracket notation [objName
methodSelector].
