错误:委托init调用的结果必须立即返回或分配给'self'

Question

这是什么意思？我如何解决它？

码:

- (id)init
{
    [super init];
    firstNumber = random() % 100 + 1;
    secondNumber = random() % 100 + 1;
    return self;
}

错误:

/Users/user/Dropbox/dev/bignerdranch_cocoa/lottery/LotteryEntry.m:15:5:{15:5-15:17}: error: the result of a delegate init call must be immediately returned or assigned to 'self' [4]

Answer 1

你没self被创造......

-(id) init {
  self = [super init];
  if(self != nil) {
    // do init stuff
  }
  return self;
}
