从@synchronized块内的方法返回

时间:2022-11-18 19:31:51

I'd just like to know if it's advised to return from a method within a @synchronized block? For example:

我想知道是否建议从@synchronized块中的方法返回?例如:

- (id)test {
   @synchronized(self) {
      if (a) return @"A";
      else return @"B";
   }
}

As opposed to:

相反:

- (id)test {
   NSString *value;
   @synchronized(self) {
      if (a) value = @"A";
      else value = @"B";
   }
   return value;
}

This sample is rather simplistic, but sometimes in a complex method it would make things simpler to be able to return from within a @synchronized block.

此示例相当简单,但有时在复杂的方法中,它可以使从@synchronized块中返回的内容变得更简单。

It's fine. @synchronized is aware of the return statement.

没关系。 @synchronized知道return语句。
