我想知道如何在编辑时UITextView
滚动它?当用户想要编辑它时,键盘显示但是UITextView
不再可滚动。所以键盘后面的所有文字都不可见。

您可以减小尺寸,如果出现在keyBoard上的textView
-(void)textViewDidBeginEditing:(UITextView *)textView
{
CGRect frame = txtAddNote.frame;
frame.size.height = 150; //Decrease your textView height at this time
txtAddNote.frame = frame;
}
-(IBAction)DoneBarBtnPress:(id)sender
{
CGRect frame = txtAddNote.frame;
frame.size.height = 212; //Original Size of textView
txtAddNote.frame = frame;
//Keyboard dismiss
[self.view endEditing:YES];
}

只需在UITextView
开始编辑时滚动视图..
-(void)textViewDidBeginEditing:(UITextView *)textView
{
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.3];
self.view.frame = CGRectMake(self.view.frame.origin.x, -160, self.view.frame.size.width, self.view.frame.size.height);
[UIView commitAnimations];
}
并在endEditing中将默认屏幕设置为低于..
-(void)textViewDidEndEditing:(UITextView *)textView
{
[textView resignFirstResponder];
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.3];
self.view.frame = CGRectMake(self.view.frame.origin.x, 0, self.view.frame.size.width, self.view.frame.size.height);
[UIView commitAnimations];
}

根据您的要求,我们使用我们的视图设置框架,请参阅下面的代码
-(void)textViewDidBeginEditing:(UITextView *)textView
{
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.3];
[yourTextView setFrame:CGRectMake(self.view.frame.origin.x,self.view.frame.origin.y,self.view.frame.size.width,self.view.frame.size.height - 160)];
[UIView commitAnimations];
}
-(void)textViewDidEndEditing:(UITextView *)textView
{
[textView resignFirstResponder];
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.3];
[yourTextView setFrame:self.view];
[UIView commitAnimations];
}
