你能硬编码IBActions和iboutlet,而不是在interfacebuilder中手动拖动它们吗?

是的,这是可能的。。。

样本代码

UIButton *btnDetail = [UIButton buttonWithType:UIButtonTypeRoundedRect] ;

        [btnDetail setFrame:CGRectMake(250.0f, 15.0f, 65.0f, 20.0f)] ;
        //btnDetail.backgroundColor = [UIColor grayColor];
        [btnDetail setTitle:@"Detail" forState:UIControlStateNormal];
        [btnDetail setTitleColor: [UIColor redColor] forState: UIControlStateNormal];
        [btnDetail.titleLabel setFont:[UIFont fontWithName:@"Verdana" size:12]];
        [btnDetail setBackgroundColor:[UIColor clearColor]];
        [btnDetail sizeThatFits:btnDetail.frame.size];
        [self.view addSubview:btnDetail];
//IBAction
        [btnDetail addTarget:self 
                   action:@selector(ShowSavingAccountDetail:)
         forControlEvents:UIControlEventTouchUpInside];

        [btnDetail setImage:[UIImage imageNamed:@"btn-detail.png"] forState:UIControlStateNormal];

尽管如此,mihirpmehta的答案是以编程方式向视图中添加UI元素并向其添加操作的正确方法。
