將UITextView或UILabel添加爲UIAlertView作爲「accessoryView」？

Apple審查允許下面的代碼，即添加一個textView或標籤作爲「accessoryView」..我讀了很多地方，它不是一個公衆暴露的API，我們不應該這樣做..但很少說我們可以..當我們發送評論時它會被拒絕嗎？請指導我...將UITextView或UILabel添加爲UIAlertView作爲「accessoryView」？

UITextView *textView = [[UITextView alloc] initWithFrame:CGRectMake(0, 0, 100, 200)]; 
textView.selectable = YES; 
textView.editable = NO; 
textView.attributedText = attributedStr; 
UIAlertView *customAlert = [[UIAlertView alloc] initWithTitle:@"Title" message:nil delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:nil, nil]; 
[customAlert setValue:textView forKey:@"accessoryView"];
