Question

我有一个文本字段和两个textViews ...当写入1中的内容时控制键盘加速...但是当我想转移另一个控件时我的键盘不让我写，因为它覆盖了整个查看...我可以解决我的问题吗？

Answer 1

您应该向上移动视图，以便键盘不覆盖textfield / textview。像这样......

- (void)textFieldDidBeginEditing:(UITextField *)textField 
{   
    if (textField == *textFieldName*) 
    {
        [UIView beginAnimations:nil context:NULL];
        [UIView setAnimationDelegate:self];
        [UIView setAnimationDuration:0.5];
        [UIView setAnimationBeginsFromCurrentState:YES];
        self.view.frame = CGRectMake(self.view.frame.origin.x, (self.view.frame.origin.y - 65.0), self.view.frame.size.width, self.view.frame.size.height);
        [UIView commitAnimations];

    }
}

- (void)textFieldDidEndEditing:(UITextField *)textField 
{   
    if (textField == *textFieldName*) 
    {
        [UIView beginAnimations:nil context:NULL];
        [UIView setAnimationDelegate:self];
        [UIView setAnimationDuration:0.5];
        [UIView setAnimationBeginsFromCurrentState:YES];
        self.view.frame = CGRectMake(self.view.frame.origin.x, (self.view.frame.origin.y + 65.0), self.view.frame.size.width, self.view.frame.size.height);
        [UIView commitAnimations];
    } 
}

并且对于textView使用：

- (void)textViewDidBeginEditing:(UITextView *)textView

和

- (void)textViewDidEndEditing:(UITextView *)textView

Answer 2

使用为uitextview和uitextfiled ....

提供的委托功能

Answer 3

- (void) animateTextField: (UITextField*) textField up: (BOOL) up
{
    const int movementDistance = 150; // tweak as needed
    const float movementDuration = 0.3f; // tweak as needed

    int movement = (up ? -movementDistance : movementDistance);

    [UIView beginAnimations: @"anim" context: nil];
    [UIView setAnimationBeginsFromCurrentState: YES];
    [UIView setAnimationDuration: movementDuration];
    self.view.frame = CGRectOffset(self.view.frame, 0, movement);
    [UIView commitAnimations];
}

- (BOOL)textViewShouldBeginEditing:(UITextView *)textView{

        [self animateTextField: textField up: YES];
}
- (void)textViewDidEndEditing:(UITextView *)textView{
            [self animateTextField: textField up: NO];

}

Answer 4

您可以将整个视图向上移动，或者只是将控件（文本字段和文本视图）向上移动..或者使视图可滚动，以便用户可以在键盘可见时向下滚动。

键盘不会从视图-phone中消失
