I just started programming Objective-C and, having a background in Java, wonder how people writing Objective-C programs deal with private methods.

I understand there

If you wanted to avoid the @interface block at the top you could always put the private declarations in another file MyClassPrivate.h not ideal but its not cluttering up the implementation.

MyClass.h

interface MyClass : NSObject {
 @private
  BOOL publicIvar_;
  BOOL privateIvar_;
}

@property (nonatomic, assign) BOOL publicIvar;
//any other public methods. etc
@end

MyClassPrivate.h

@interface MyClass ()

@property (nonatomic, assign) BOOL privateIvar;
//any other private methods etc.
@end

MyClass.m

#import "MyClass.h"
#import "MyClassPrivate.h"
@implementation MyClass

@synthesize privateIvar = privateIvar_;
@synthesize publicIvar = publicIvar_;

@end
