Customize an existing button in Objective C - ios

Question

I'd like to be able to customize any buttons I'll create within a specific style of my app. I was trying to create a new class which will consist of all my settings, so every time I add a new button I can use methods of the class to customize the new button.
I'm a very new to the iOS programming so I quess I might've been doing something wrong, but that's what I've got so far:
I created the class with settings
#import "CustomButton.h"
#implementation CustomButton
-(UIButton *) setButtonWithType{
self.layer.cornerRadius = 25;
self.layer.shadowColor = [UIColor blackColor].CGColor;
self.layer.shadowOffset = CGSizeMake(1.5f, 1.5f);
self.layer.shadowOpacity = 1.0f;
self.layer.shadowRadius = 0.0f;
self.layer.masksToBounds = NO;
CAGradientLayer *gradient = [CAGradientLayer layer];
gradient.frame = self.bounds;
gradient.startPoint = CGPointMake(0.5, 0.5);
gradient.endPoint = CGPointMake(0.0, 0.5);
gradient.colors = [NSArray arrayWithObjects:(id)[UIColor whiteColor].CGColor,(id)[UIColor colorWithRed:230/255.0 green:230/255.0 blue:230/255.0 alpha:1.0].CGColor, nil];
gradient.cornerRadius = self.layer.cornerRadius;
[self.layer insertSublayer:gradient atIndex:0];
return self;
}
#end
ViewController.h
#interface ViewController : UIViewController
#property (weak, nonatomic) IBOutlet UIButton *button;
#end
ViewController.m
#import "ViewController.h"
#import "CustomButton.h"
#interface ViewController ()
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
CustomButton *btn = [[CustomButton alloc] init];
self.button = [btn setButtonWithType];
//rest of the code
Any ideas how to make it works?
Or do I need to use a very different approach?
Thank you!!

You may find success doing this as a Category (lots of examples out there)...
UIButton+ShadowRoundedGradient.h
#import <UIKit/UIKit.h>
#interface UIButton (ShadowRoundedGradient)
- (void) makeMe;
#end
UIButton+ShadowRoundedGradient.m
#import "UIButton+ShadowRoundedGradient.h"
#implementation UIButton (ShadowRoundedGradient)
- (void) makeMe {
self.layer.cornerRadius = 25;
self.layer.shadowColor = [UIColor blackColor].CGColor;
self.layer.shadowOffset = CGSizeMake(1.5f, 1.5f);
self.layer.shadowOpacity = 1.0f;
self.layer.shadowRadius = 0.0f;
self.layer.masksToBounds = NO;
CAGradientLayer *gradient = [CAGradientLayer layer];
gradient.frame = self.bounds;
gradient.startPoint = CGPointMake(0.5, 0.5);
gradient.endPoint = CGPointMake(0.0, 0.5);
gradient.colors = [NSArray arrayWithObjects:(id)[UIColor whiteColor].CGColor,(id)[UIColor colorWithRed:230/255.0 green:230/255.0 blue:230/255.0 alpha:1.0].CGColor, nil];
gradient.cornerRadius = self.layer.cornerRadius;
[self.layer insertSublayer:gradient atIndex:0];
}
#end
ViewController.h
#import <UIKit/UIKit.h>
#interface ViewController : UIViewController {
#property (weak, nonatomic) IBOutlet UIButton *button;
}
#end
ViewController.m
#import "ViewController.h"
#import "UIButton+ShadowRoundedGradient"
#interface ViewController ()
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
[self.button makeMe];
//rest of the code
}
