Ios NSString子字符串

我有一根这样的绳子

12,23,45,3,12

我想做的是得到每个数字，并用一个数组值进行检查。如何将每个值作为子字符串进行检查

---

谢谢

将此字符串打断为数组

NSString *string = @"12,23,45,3,12,";
NSArray *array = [string componentsSeparatedByString:@","];

然后可以与数组进行比较

编辑：

根据您的注释，您希望检查其他主数组中存在的所有字符串值

NSString *string = @"12,23,45,3,12";
NSArray *array = [string componentsSeparatedByString:@","];
//below is the main-other-array
NSArray *toCheckArray = @[@"124",@"23",@"45",@"3",@"12",@"1000"];

BOOL arrayIsContainedInToCheckArray = YES;

for (NSString *arrayObj in array) {
    if (![toCheckArray containsObject:arrayObj]) {
        arrayIsContainedInToCheckArray = NO;
    }
}
NSLog(@"%@",arrayIsContainedInToCheckArray?@"All exist":@"All doesn't exist");

用这个，它会帮助你

NSArray *detailArray = [yourString componentsSeparatedByString:@","];

用这个，它会帮助你

NSArray *detailArray = [yourString componentsSeparatedByString:@","];

也许它能帮助你：

NSString *str = @"12,23,45,3,12";
NSArray *strArray = [str componentsSeparatedByString:@","];
NSArray * anotherArray = nil; // have some value
for (NSString * value in strArray)
{
    int intVal = [value integerValue]; // here is your separate value
    for (int i = 0; i < [anotherArray count]; i++) // You can check against another array
    {
        id anotherVal = [anotherArray objectAtIndex:i];

        // Here you can check intVal and anotherVal from another array

    }
}

NSString*str=@“12,23,45,3,12”；
NSArray*strArray=[str组件由字符串分隔：@“，”]；
NSArray*另一个数组=nil；//有价值
for（NSString*字符串中的值）
{
int intVal=[value integerValue]；//这是单独的值
for（int i=0；i<[anotherArray count]；i++）//您可以对照另一个数组进行检查
{
id anotherVal=[anotherArray objectAtIndex:i]；
//在这里，您可以从另一个数组中检查intVal和另一个VAL
}
}

它可能会帮助您：

NSString *str = @"12,23,45,3,12";
NSArray *strArray = [str componentsSeparatedByString:@","];
NSArray * anotherArray = nil; // have some value
for (NSString * value in strArray)
{
    int intVal = [value integerValue]; // here is your separate value
    for (int i = 0; i < [anotherArray count]; i++) // You can check against another array
    {
        id anotherVal = [anotherArray objectAtIndex:i];

        // Here you can check intVal and anotherVal from another array

    }
}

NSString*str=@“12,23,45,3,12”；
NSArray*strArray=[str组件由字符串分隔：@“，”]；
NSArray*另一个数组=nil；//有价值

}

如果这6个值存在于数组中，是否要检查它们？或者要检查数组中是否存在任何值？要检查所有6个值检查编辑的答案…是否要检查数组中是否存在这6个值？或者要检查数组中是否存在任何值？要检查所有6个值检查已编辑的答案…嵌套循环将过度杀死嵌套循环将过度杀死
