推荐答案

在这种情况下，您需要创建自己的清除按钮图像。我建议拍摄清晰按钮的屏幕截图并在photoshop中进行编辑。

You'll need to create your own clear button image in this case. I would suggest taking a screenshot of the clear button and editing in photoshop.

您可以拍摄该图像并使用图像尺寸创建UIButton。从那里你可以将它设置为UITextField的rightView。像这样：

You can take that image and create a UIButton with the image dimensions. From there you can set it as the UITextField's rightView. Like so:

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setImage:[UIImage imageNamed:@"clear_button.png"] forState:UIControlStateNormal];
[button setFrame:CGRectMake(0.0f, 0.0f, 15.0f, 15.0f)]; // Required for iOS7
theTextField.rightView = button;
theTextField.rightViewMode = UITextFieldViewModeWhileEditing;

我在没有语法检查的情况下键入了这个，但是在运行它之前你不想这么做。您还需要将clear_button.png替换为您的图像名称。

I typed that without syntax checking and what not so you'll want to check it out before running it. You'll also want to replace clear_button.png with whatever your image name is.

您还需要编写自己的方法来清除文本字段。

You'll also need to write your own method to clear the text field.
