我的代码有问题.当我在编辑本应被键盘弹出隐藏的UITextField时，我正在try 移动UIScrollView.
我现在正在移动主框架，因为我不知道如何在代码中"向上滚动".
所以，我做了一些代码，它工作得很好，但是当我编辑一个UItextfield并切换到另一个UITextField，而没有按下‘Return’按钮，主视图就会变成waaayyyy到更高的位置.
我用变量大小、距离和textFieldRect计算了NSLog().起源正如你在下面看到的.当我把两个UITextField放在同一个位置(y原点)并进行这个特殊的"切换"(不按回车键)时，我得到的数字是相同的，而我的代码在第一次编辑UITextField时运行良好，但在第二次编辑时运行不好.
看看这个:
- (void)textFieldDidBeginEditing:(UITextField *)textField {
{
int size;
CGRect textFieldRect = [self.view.window convertRect:textField.bounds fromView:textField];
size = textFieldRect.origin.y + textFieldRect.size.height;
if (change == FALSE)
{
size = size - distance;
}
if (size < PORTRAIT_KEYBOARD_HEIGHT)
{
distance = 0;
}
else if (size > PORTRAIT_KEYBOARD_HEIGHT)
{
distance = size - PORTRAIT_KEYBOARD_HEIGHT + 5; // +5 px for more visibility
}
NSLog(@"origin %f", textFieldRect.origin.y);
NSLog(@"size %d", size);
NSLog(@"distance %d", distance);
CGRect viewFrame = self.view.frame;
viewFrame.origin.y -= distance;
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationDuration:KEYBOARD_ANIMATION_DURATION];
[self.view setFrame:viewFrame];
[UIView commitAnimations];
change = FALSE;
}
- (void)textFieldDidEndEditing:(UITextField *)textField
{
change = TRUE;
CGRect viewFrame = self.view.frame;
viewFrame.origin.y += distance;
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationDuration:KEYBOARD_ANIMATION_DURATION];
[self.view setFrame:viewFrame];
[UIView commitAnimations];
}
有什么 idea 吗？
