我们在用键盘录入的时候，有可能会遮挡录入框，所以我们应调整UIView的位置，使其不被遮挡。我写了一个通用的方法可以解决这个问题：
??1. [代码][C/C++]代码
- (void)moveView:(UITextField *)textField leaveView:(BOOL)leave
{
UIView *accessoryView = textField.inputAccessoryView;
UIView *inputview = textField.inputView;
int textFieldY = 0;
int accessoryY = 0;
if (accessoryView && inputview)
{
CGRect accessoryRect = accessoryView.frame;
CGRect inputViewRect = inputview.frame;
accessoryY = 480 - (accessoryRect.size.height + inputViewRect.size.height);
}
else if (accessoryView)
{
CGRect accessoryRect = accessoryView.frame;
accessoryY = 480 - (accessoryRect.size.height + 216);
}
else if (inputview)
{
CGRect inputViewRect = inputview.frame;
accessoryY = 480 -inputViewRect.size.height;
}
else
{
accessoryY = 264; //480 - 216;
}
CGRect textFieldRect = textField.frame;
textFieldY = textFieldRect.origin.y + textFieldRect.size.height + 20;
int offsetY = textFieldY - accessoryY;
if (!leave && offsetY > 0)
{ http://www.huiyi8.com/vi/
int y_offset = -5;
y_offset += -offsetY;
CGRect viewFrame = self.view.frame;
viewFrame.origin.y += y_offset;
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationDuration:0.3];
[self.view setFrame:viewFrame];
[UIView commitAnimations];
}
else
{ vi素材大全
CGRect viewFrame = CGRectMake(0, 20, 320, 460);
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationDuration:0.3];
[self.view setFrame:viewFrame];
[UIView commitAnimations];
}
}
2. [代码]用法很简单，在UITextFieldDelegate的两个方法里分别调用一下这个方法就ＯＫ了，如下示例：
- (void)textFieldDidBeginEditing:(UITextField *)textField
{
[self moveView:textField leaveView:NO];
}
- (void)textFieldDidEndEditing:(UITextField *)textField;
{
[self moveView:textField leaveView:YES];
}
