UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(0, 0, 100, 30)]textField.returnKeyType = UIReturnKeySearch; //设置按键类型textField.enablesReturnKeyAutomatically = YES; //这里设置为无文字就灰色不可点

 

在代理方法中响应

- (BOOL)textFieldShouldReturn:(UITextField *)textField{    [self searchAction];    [textField resignFirstResponder];    return YES;}
