ios - 具有多种颜色的 UIAlertController 消息

Question

我想把第二句话改成不同的颜色。

UIAlertController * alert=[UIAlertController
    alertControllerWithTitle:@"Warning!!!" message:@"This is the first sentence.\r\n\n
This is the second sentence I want a different color.\r\n\n
This is the third sentence.)"
preferredStyle:UIAlertControllerStyleAlert];
