iOS Xcode 4 - Braces Missing?

[Ratspootin]

I just started learning Objective C last night so I'm completely new to it, but shouldn't Xcode 4 put braces after the view controller line when you make a new project?

This is what Xcode 4 creates by default:

This is what I'm assuming it's supposed to be based on Xcode 3 tutorials:

Did Xcode 3 do this automatically because every video/website/book based on Xcode 3 I'm using has it there when a new project is created.

They are no longer needed, do not worry about it.

The curly braces are needed if you declare instance variables

http://clang.llvm.org/doxygen/ParseObjc_8cpp_source.html

00121 ///   objc-class-interface:
00122 ///     '@' 'interface' identifier objc-superclass[opt]
00123 ///       objc-protocol-refs[opt]
00124 ///       objc-class-instance-variables[opt]
00125 ///       objc-interface-decl-list
00126 ///     @end

00257   if (Tok.is(tok::l_brace))
00258     ParseObjCClassInstanceVariables(ClsType, tok::objc_protected, atLoc);

01111 ///   objc-class-instance-variables:
01112 ///     '{' objc-instance-variable-decl-list[opt] '}'

Freakin IPad. LOL. Not sure why it didn't post properly. In any event, I had something that went like this.

They are no longer needed, do not worry about it. Unless of course you need instance variables in which case you will need to add the curly braces back. Apple seems to push properties. I'm guessing that apple changed the template with Xcode 4. Here is a nice overview of the header/implementation files. http://www.idev101.com/learn/objective_c_classes.html


My apologies for the confusion. [self embarrassed].

No worries! The extra information that you intended to post makes the original statement much clearer
