ios - 从 UIController 调用 UIView

Question

我正在尝试从我的 ViewController 调用 UIView FirstScreen。

但是我不知道该怎么做。

View Controller :

#import "ViewController.h"
#import "FirstScreen.h"

@interface ViewController ()
{
    FirstScreen *f; 
}

FirstScreen.m:

#import "FirstScreen.h"       
@implementation FirstScreen

- (id)initWithFrame:(CGRect)frame
{
    self = [super initWithFrame:frame];
    if (self) {
        [self didLoad];
    }
    return self;
}

-(void) didLoad{
    [self addLabel];
    [self addImageView];
}

@implementation FirstScreen

 - (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
    [self didLoad];
}
return self;
}

-(void) didLoad
{
 f = [[FirstScreen alloc] initWithFrame:CGRectMake(0, 0, self.view.size.width, self.view.size.height)];
[self.view addSubview:f];
}
