问题描述
有没有一种方法可以在循环内创建变量.基本上像这样,除了变量variable1,variable2和variable3将存在.
Is there a way to create variables inside of a loop. Basically something like this, except that the variables variable1, variable2 and variable3 would exist.
int x;
for (x = 1; x < 4; x++) {
int variable[x];
variable[x] = x;
}
推荐答案
没有,没有.
但是您可以执行以下操作:
But you can do something like this:
NSMutableDictionary *dictionary = [[NSMutableDictionary alloc] init];
for (int i = 0; i < 4; i++) {
[dictionary setObject:[NSNumber numberWithInt:i] forKey:[NSString stringWithFormat:@"%i", i]];
}
这会将您的x
保存在NSMutableDictionary
中,这与其他语言中的关联数组相当.
This will save your x
s in an NSMutableDictionary
, which is comparable to an associative array in other languages.
