ios – 以编程方式创建文本字段

我正在使用Xcode 4.6.1.我想知道如何在同一个视图控制器上创建各种文本字段,用它们之间的一些空格分隔,并以编程方式设置文本.

- (void)viewDidLoad
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

    //first one
    UITextField *tf = [[UITextField alloc] initWithFrame:CGRectMake(45, 30, 200, 40)];
    tf.textColor = [UIColor colorWithRed:0/256.0 green:84/256.0 blue:129/256.0 alpha:1.0];
    tf.font = [UIFont fontWithName:@"Helvetica-Bold" size:25];
    tf.backgroundColor=[UIColor whiteColor];
    tf.text=@"Hello World";

    //second one
    UITextField *tf1 = [[UITextField alloc] initWithFrame:CGRectMake(45, tf.frame.origin.y+75, 200, 40)];
    tf1.textColor = [UIColor colorWithRed:0/256.0 green:84/256.0 blue:129/256.0 alpha:1.0];
    tf1.font = [UIFont fontWithName:@"Helvetica-Bold" size:25];
    tf1.backgroundColor=[UIColor whiteColor];
    tf1.text=@"second field";

    //and so on adjust your view size according to your needs
    UIView *view = [[UIView alloc] initWithFrame:CGRectMake(100, 200, 400, 400)];
    [view addSubview:tf];
    [view addSubview:tf1];

    [self.view addSubview:view];
