对于这一个…NSNumber*fortyTwo=@42；//相当于[NSNumber NUMBER WITHIT:42]NSNumber*fortyTwoUnsigned=@42U；//相当于[NSNumber numberWithUnsignedInt:42U]NSNumber*fortyTwoLong=@42L；//相当于[NSNumber numberWithLong:42L]NSNumber*fortyTwoLongLong=@42LL；//相当于[NSNumber numberWithLongLong:42LL]啊，对不起，我问的时候已经是凌晨1点了。刚刚醒来。我现在就去试试，你的两条线都洗过了，但还是不行。它表示不兼容的转换类型
