如何在鍵盤出現時使UITextView可滾動？

Question

我想知道在編輯時如何滾動我的UITextView？當用戶想要編輯它時，鍵盤顯示，但UITextView不再滾動。所以鍵盤後面的所有文本都不可見。

Answer 1

您可以減少整型尺寸你的TextView在鍵盤出現

-(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]; 
} 

Answer 2

只是滾動視圖時UITextView開始編輯這樣的..

-(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]; 

} 

和endEditing只是設置默認屏幕像波紋管..

-(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]; 
} 

UPDATE

這裏有您的要求我們設置框架與我們的看法見波紋管代碼

-(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]; 
    }
