在objective-c中获取for语句中的数组索引 [英] get the array index in for statement in objective-c
问题描述
我陷入了一个愚蠢的混乱......
我不仅要获得数组的值,还要获取值的索引。
在PHP中它很简单: foreach($ array as $ key-> $ value)
这里$ key将包含索引值。
是不是有类似的方法在目标c?
我还能做到这一点吗?
请帮忙! :((
I am stuck in a stupid mess...
I want to get not only the value of an array but also the index of the values.
In PHP it's simple: foreach($array as $key->$value)
Here $key will contain the index value.
Isn't there a similar approach in objective c?
How else could I achieve this?
Please help! :((
推荐答案
与php不同的数组编号为0大小。我猜你在谈论字典。如果是这样的话。你可以用[dict allKeys]获得密钥数组。
所以这样的东西应该可以工作:
Arrays not like in php are numbered 0-size of array. I guess you talking about dictionary's. If so you can get array of key with [dict allKeys]. so something like this should work:
for(id key in [dict allKeys]){
id value = [dict objectForKey:key];
}
