由於未捕獲異常而終止應用程序NSInvalidArgumentException，原因：索引無效

-1

我是IOS開發新手。當我運行我的應用程序時，出現以下錯誤。任何人都可以幫助我..由於未捕獲異常而終止應用程序NSInvalidArgumentException，原因：索引無效

我已將UITextView放在TableViewCell的內部。而且我已將'one \ n'設置爲UITextView的文本。

我的代碼：

- (id)initWithFrame:(CGRect)frame withIndexPath:(NSArray *)indexPath 
{ 
    self = [super initWithFrame:frame]; 
    if (self) { 
     mIndexPath = indexPath; 
     mRange = NSMakeRange(0,4); 

     self.delegate = self; 
     self.attributedText = @"one\n";  
     self.scrollEnabled = NO; 
    } 
    return self; 
} 

- (void)textViewDidBeginEditing:(TextView *)textView 
{ 
    [self updateRangeForSelection]; 
} 

- (void)updateRangeForSelection 
{ 
    NSRange selectedRange = self.selectedRange; 
    NSLog(@"%d",selectedRange.location); 
}

當我在UITextView挖掘，我被選中作爲Range（3,0）。在記錄所選範圍後，我自己得到以下異常。

我在做什麼錯在這裏？
