ios - 带有下拉按钮的 UITextField

Question

UITextField 可以单独使用代码来实现这个 UI，还是我需要为此使用图像或其他组件？像按钮，标签。

Answer 1

试试这个。

UIImageView *imgViewForDropDown = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 35, 35)];
imgViewForDropDown.image = [UIImage imageNamed:@"dropDown.png"];
yourTextField.rightView = imgViewForDropDown;
yourTextField.rightViewMode = UITextFieldViewModeAlways;

对于 Swift 代码:

let imgViewForDropDown = UIImageView()
imgViewForDropDown.frame = CGRect(x: 0, y: 0, width: 30, height: 48)
imgViewForDropDown.image = UIImage(named: "ic_keyboard_arrow_down_white")
yourTextField.rightView = imgViewForDropDown
yourTextField.rightViewMode = .always
