how to make a single method in a class to private in Objective-c?

Any of those help There's no concept of private methods in Objective-C. What you can do, however, is obmitting the method in the header file and adding a category in a private file.
Usually this is down like this:

Is it possible to make the -init method private in Objective-C?

With these it helps Objective-C, like Smalltalk, has no concept of "private" versus "public" methods. Any message can be sent to any object at any time.
What you can do is throw an NSInternalInconsistencyException if your -init method is invoked:
code :
- (id)init {
    [self release];
    @throw [NSException exceptionWithName:NSInternalInconsistencyException
                                   reason:@"-init is not a valid initializer for the class Foo"
                                 userInfo:nil];
    return nil;
}

Can't make a private method in C++ return a pointer to a private nested class

around this issue This one doesn't want to compile: , Had forgotten to add the class scope in the .cpp, i.e.
code :
class MainClass::NestedClass * getNestedClassFor(int i)
{
   //...
}
class MainClass::NestedClass * MainClass::getNestedClassFor(int i)
{
   //...
}

How to make an objective-c method private

I think the issue was by ths following , One fairly solid solution to this is to use a static c method to do your initialization. All valid c is valid objective-c after-all.
So for example, CustomSuperclass.h:
code :
#import <Foundation/Foundation.h>
@interface CustomSuperclass : NSObject
@property (nonatomic) NSUInteger integer;
@end
#import "CustomSuperclass.h"
@implementation CustomSuperclass
@synthesize integer = _integer;
static void initializeInstance(CustomSuperclass *self) {
    self.integer = 9;
}
-(id)init{
    if ((self = [super init])){
        initializeInstance(self);
    }
    return self;
}
@end
#import "CustomSuperclass.h"
@interface CustomSubclass : CustomSuperclass
@end
#import "CustomSubclass.h"
@implementation CustomSubclass
// Obviously we would normally use (CustomSubclass *self), but we're proving a point with identical method signatures.
void initializeInstance(CustomSuperclass *self) {
    self.integer = 10;
}
-(id)init{
    if ((self = [super init])){
        // We won't call this classes `initializeInstance()` function.
        // We want to see if this one overrides it's superclasses version.
    }
    return self;
}
@end
CustomSuperclass *instanceOfSuperclass = [[CustomSuperclass alloc] init];
NSLog(@"superclass integer:%i", instanceOfSuperclass.integer);

CustomSubclass *instanceOfSubclass = [[CustomSubclass alloc] init];
NSLog(@"subclass integer:%i", instanceOfSubclass.integer);
superclass integer:9
subclass integer:9
/* Designated initializer */
-(id)initWithFile:(NSString *)file andURL:(NSURL *)url{
    if ((self = [super init])){
        _url = url;
        _file = file;
        // Initialization of new instance code here.
    }
    return self;
}
-(id)initWithFile:(NSString *)file{
    return [self initWithFile:file andURL:nil];
}
-(id)initWithURL:(NSURL *)url{
    return [self initWithFile:nil andURL:url];
}
-(void)initialize_CustomUIView{
    // Common init tasks
}
-(id)initWithFrame:(CGRect)frame{
    if ((self = [super initWithFrame:frame])){
        [self initialize_CustomUIView];
    }
    return self;
}
-(id)initWithCoder:(NSCoder *)aDecoder{
    if ((self = [super initWithCoder:aDecoder])){
        [self initialize_CustomUIView];
    }
    return self;
}
-(id)init{
    if ((self = [super init])){
        [self initialize_CustomUIView];
    }
    return self;
}

Hope that helps To create an instance of class if by it's name use NSClassFromString:
