使用inputView时,防止在UITextField中编辑文本并隐藏光标/插入符号/放大镜

Question

如何在UITextField隐藏光标/插入符号/放大镜的同时防止编辑文本,但仍然显示键盘,因为我使用的inputView是UIPickerView/ UIDatePickerView？

设置userInteractionEnabled为NO不起作用,因为它不再接收任何触摸并且不会显示键盘.

Answer 1

子类UITextField

//Disables caret
- (CGRect)caretRectForPosition:(UITextPosition *)position
{
    return CGRectZero;
}

//Disables magnifying glass
-(void)addGestureRecognizer:(UIGestureRecognizer *)gestureRecognizer
{
    if ([gestureRecognizer isKindOfClass:[UILongPressGestureRecognizer class]])
    {
        gestureRecognizer.enabled = NO;
    }
    [super addGestureRecognizer:gestureRecognizer];
}

在你的UITextFieldDelegate中

//Prevent text from being copied and pasted or edited with bluetooth keyboard.
- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {
    return NO;
}

现在只需从UIPickerView/UIDatePicker的结果中以编程方式设置文本.

Answer 2

在iOS 7中隐藏光标要简单得多.仍然需要一些技巧来禁用放大镜

textField.tintColor = [UIColor clearColor];

Answer 3

我希望这对你有所帮助.

设置光标UIColor - > Empty.在UI中,它将被隐藏.

[[self.textField valueForKey:@"textInputTraits"] setValue:[UIColor clearColor] forKey:@"insertionPointColor"];
