推荐答案

如果您有这样的图像，UITextField有 rightView 属性 - 然后您可以轻松地将ImageView对象设置为rightView：

UITextField has a rightView property, if you have image like this- then You can easly set ImageView object to rightView:

UITextField *myTextField = [[UITextField alloc] init];

myTextField.rightViewMode = UITextFieldViewModeAlways;
myTextField.rightView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"downArrow.png"]];
