IOS 關於鍵盤遮擋編輯地區(UITextFiled/UITextView)的問題

1.自定方法 ,用於行動裝置檢視

-(void)moveInputBarWithKeyboardHeight:(float)_CGRectHeight withDuration:(NSTimeInterval)_NSTimeInterval;

2.註冊監聽

NSNotificationCenter *defaultCenter = [NSNotificationCenter defaultCenter];

    [defaultCenter selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];

    [defaultCenter addObserver:self selector:@selector(keyboardWillHide:) name:UIKeyboardWillHideNotification object:nil];

3.實現方法

- (void)keyboardWillShow:(NSNotification *)notification {

    NSDictionary *userInfo = [notification userInfo];

    NSValue* aValue = [userInfo objectForKey:UIKeyboardFrameEndUserInfoKey];

    CGRect keyboardRect = [aValue CGRectValue];

    NSValue *animationDurationValue = [userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey];

    NSTimeInterval animationDuration;

    [animationDurationValue getValue:&animationDuration];

    if(nil==self.myTextView) return;//    self.editTextView 為被鍵盤遮擋住的控制項

    CGRect rect = self.myTextView.frame;

    float textY = rect.origin.y + rect.size.height; 

    float bottomY = SCREENHEIGHT - textY;//得到下邊框到底部的距離  SCREENHEIGHT 為當前裝置的高度

    if(bottomY >=keyboardRect.size.height ){//鍵盤預設高度,如果大於此高度，則直接返回

        return;

    }

    float moveY = keyboardRect.size.height - bottomY;

    [self moveInputBarWithKeyboardHeight:moveY withDuration:animationDuration];

}

 

- (void)keyboardWillHide:(NSNotification *)notification {

    NSDictionary* userInfo = [notification userInfo];

    NSValue *animationDurationValue = [userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey];

    NSTimeInterval animationDuration;

    [animationDurationValue getValue:&animationDuration];

    [self moveInputBarWithKeyboardHeight:0.0 withDuration:animationDuration];

}

 

-(void)moveInputBarWithKeyboardHeight:(float)_CGRectHeight withDuration:(NSTimeInterval)_NSTimeInterval{

  CGRect rect1 = self.view.frame;

    [UIView beginAnimations:nil context:NULL];

    [UIView setAnimationDuration:_NSTimeInterval];

    rect1.origin.y = -_CGRectHeight;//view往上移動

    self.view.frame = rect1;

    [UIView commitAnimations];

}

測試的時候是用的4s真機測試的,一切都很完美,但是前幾天同事用6 測的時候發現一個問題,就是編輯的時候能達到不遮擋控制項的效果,但是發現輸入中文的時候有時候會莫名的敲不出中文,會出現一連串的字元,而且刪除的時候字元刪不掉,幾乎是越刪越多.但是用4S測了很多遍都沒有出現這個問題.這幾天一直在想這個問題是什麼造成的,望知道的高人們,指點一二.感謝!(用的UITextView)
