问题描述

在iPhone中，我有一个具有UITextField的视图.当我点击UITextField的清除按钮时，键盘将关闭，而不是清除UITextField中的文本.在iPad上，它可以正常工作.我该怎么做才能解决此问题?

In iPhone, I have a view which has a UITextField. When I tap on the clear button of UITextField's the keyboard dismissed instead of clearing the text in the UITextField. On an iPad it is working correctly. What can I do to fix this?

推荐答案

只需清除字段resignFirstResponder(如果要隐藏键盘)，然后返回NO/false

Just clear the field, resignFirstResponder (if you want to hide keyboard) and return NO/false

注意:设置UITextField

清除按钮->编辑时显示

因此它将在文本字段中进行编辑时显示清除按钮.

so it will display the clear button while editing in the text field.

//Objective-C

-(BOOL)textFieldShouldClear:(UITextField *)textField
{
    textField.text = @"";
    [textField resignFirstResponder];
    return NO;
}

//Swift

func textFieldShouldClear(textField: UITextField) -> Bool {
    textField.text = ""
    textField.resignFirstResponder()
    return false
}
