ios - 如何在单击添加按钮时动态添加新的文本字段

Question

刚才我单击按钮时，我动态创建了文本字段
我的代码是:

-(void)clickonAdd
{
     CGRect textfieldFrame = CGRectMake(18, 350,309,35.0);
     UITextField *textField = [[UITextField alloc]initWithFrame:textfieldFrame];
     textField.borderStyle = UITextBorderStyleRoundedRect;
     textField.font = [UIFont systemFontOfSize:15];
     textField.placeholder = @"Select Item List";
     textField.autocorrectionType = UITextAutocorrectionTypeNo;
     textField.keyboardType = UIKeyboardTypeDefault;
     textField.returnKeyType = UIReturnKeyDone;
     textField.clearButtonMode = UITextFieldViewModeWhileEditing;
     textField.contentVerticalAlignment =UIControlContentVerticalAlignmentCenter;
     textField.delegate = self;
     [self.view addSubview:textField];
}

现在我想添加更多具有不同位置的文本框，当单击相同的按钮时...您能帮我吗...谢谢

尝试这个 ...

@interface ViewController ()
{
    CGFloat y;
    CGFloat x;
}

- (void)viewDidLoad 
{
    [super viewDidLoad];

    y = 0;
    x = 0;
}

-(void)clickButtonAdd
{
    UITextField *textField;
    textField.frame = CGRectMake(x, y,100,30);
    textField = [[UITextField alloc]initWithFrame:textfieldFrame];
    textField.borderStyle = UITextBorderStyleRoundedRect;
    [self.view addSubview:textField];

    x  = x + 120;
    y =  y + 40;
}
