是否能够找到标语,具体加以说明。
例如,我可以在实验室使用。
$objectname="foo";
$foo="bar";
echo $$objectname="bar";
这是可能的。 逐个名称就是这样做的适当功能。

如果您储存被称作不动产或某种字典的物体,就有可能这样做。 然后,你可以做这样的事情:
// Put object into dictionary
[dictionaryWithObjects setValue:someNamedObject forKey:@"someNamedObject"];
// and then retrieve it
id object = [dictionaryWithObjects valueForKey:@"someNamedObject"];
我不相信目标C会支持这一水平的美术。
这种办法并不像PHP那样看待,但是,如果是,有可能从扼杀中找到一个班子。 您使用。
例如,以下两条对等:
id a = [[NSClassFromString(@"NSString") alloc] init];
id a = [[NSString alloc] init];
您可以使用<条码>NSClassFromString(),以获得一个班级,但就某个物体而言,我认为这是不可能的。
