如何添加一个从数组中调用数字的ui按钮，并将电话号码显示为按钮标题

Question

anotherViewController.myLabel = [NSString stringWithFormat:@"Telephone %@", 
      anotherViewController.title];

这是一个previus标签的声明，但我不知道如何为按钮做这个... 数据数组以此格式定位

  phoneNumbers = [[NSArray alloc] initWithObjects:@"6940313388", @"4045434218", nil ];
self.phoneNumbers =phoneNumbers;

然后只需添加标签

 theLabel.text = myLabel;

其中mylabel是NSString

请帮助我一直试图解决这个问题很长一段时间......

这是我用来制作按钮的代码。然后将按钮添加到视图中！

编辑：您可以将setTitle：part的一部分更改为您希望按钮显示为标题的任何字符串。

    //create the button
    UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];

    //sets its size
    [button setFrame:CGRectMake(10, 10, 300, 50)];

    //set title, font size and font color
    [button setTitle:@"Sign Up" forState:UIControlStateNormal];
    [button setFont:[button.font fontWithSize:22]];
    [button setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
    [button setBackgroundImage:[UIImage imageNamed:@"green_btn_bg.png"] forState:UIControlStateNormal];
    //set action of the button
    [button addTarget:self action:@selector(signUp:)
     forControlEvents:UIControlEventTouchUpInside];
