我有
NSDistantObject
类对象数组。
NSLog(@"%@", [[saveClassObject objectAtIndex:0] connectionForProxy]);
NSLog(@"%@", NSStringFromClass([[saveClassObject objectAtIndex:0] class]));
if ([[saveClassObject objectAtIndex:0] isKindOfClass:[NSDistantObject class]]) {
NSLog(@"Yes");
}
else {
NSLog(@"NO");
}
上述代码的输出是

NSStringFromClass
返回包含 NSDistantObject
类对象的 saveClassObject 数组。 isKindofClass
同样返回“否”。为什么?
NSProxy
的 -isKindOfClass:
调用 forwardInvocation:
。它的目的是测试代理所代表的对象的类,而不是代理本身。
isProxy
来代替。class
等于 [NSDistantObject class]
或调用 isSubclassOfClass:
。
