NSPredicate with (match OR match) AND 匹配

Question

我想要一个谓词：

NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(self isKindOfClass: %@ || self isKindOfClass: %@) AND isActive == YES", [TestClass1 class], [TestClass2 class]];

但是 () 并没有像我想象的那样在 if stmt 中工作：

if ((condition1 || condition2) && otherCondition) {
}

如果 'condition1' 或 'condition2' 为真加上 'otherCondition' 为真，则 if stmt 为真。

我可以用 NSPredicate 做到这一点吗？

Answer 1

[NSPredicate predicateWithFormat:@"(isActive == YES AND (class == %@ OR class == %@))", [TestClass1 class], [TestClass2 class]];
