UIButton not respond in UIView - objective-c

Question

UIButton in my view does not respond when I click it. Some one figure
out what I am doing wrong? Here is my entire code:
MyView.h
#interface Myview : UIView
#end
MyView.m
#import "MyView.h"
- (init){
self = [super init];
if(self)
[self createButton];
return self;
}
- (void) createButton{
UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(100,100,100,50)];
[button setTitle:#"Go" forState:UIControlStateNormal];
[button addTarget:self
`action:#selector(goAction)
forControlEvents:UIControlEventTouchUpInside];
[self addSubview:button];
}
- (void) goAction{
NSString *test = #"Some text";
}
MyViewController.m
- (id) init{
self = [super init];
if (self) {
MyView *myview = [[MyView alloc] init];
[self.view addSubview:myview];
}
return self;
}`
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
}
ViewController.m
#import "ViewController.h"
#import "MyViewController.h"
#interface ViewController ()
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
MyViewController *myTestView = [[MyViewController alloc] init];
[self.view addSubview:myTestView.view];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#end

The reason why clicks does not work is that you don't set frame of MyView
This way it works (although I still don't understand why you need to add one ViewController into another)
#implementation MyViewController
- (instancetype)init
{
self = [super init];
if (self) {
MyView *myview = [[MyView alloc] init];
myview.frame = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.width);
[self.view addSubview:myview];
}
return self;
}
