问题描述
这应该是微不足道的......我想,但我找不到如何将Struct变量包装到 NSObject
中的方法。有没有办法这样做?如果没有,我将如何将结构添加到 NSMutableArray
?
this is supposed to be trivial… I think, but I can't find a way how to wrap a Struct variable into an NSObject
. Is there a method to do so? If not, how would I go about adding a struct into an NSMutableArray
?
谢谢。
推荐答案
嗯,试着在
Hm, try to look at the NSValue
at https://developer.apple.com/documentation/foundation/nsvalue
您可以像
struct aStruct
{
int a;
int b;
};
typedef struct aStruct aStruct;
然后将其换行到 NSValue
对象如:
Then sort of "wrap" it to an NSValue
object like:
aStruct struct; struct.a = 0; struct.b = 0;
NSValue *anObj = [NSValue value:&struct withObjCType:@encode(aStruct)];
NSArray *array = @[anObj];
从 NSValue
中拉出结构:
NSValue *anObj = [array firstObject];
aStruct struct;
[anObj getValue:&struct];
我想稍后,你可以从NSValue中获得一个更好的类别= D
I guess later on, you can have a category from NSValue to make that better =D
