String Array iPhone的SubStrings

Question

我有一个数组,见下文,

NSMutableArray *myArray=[[NSMutableArray alloc]initWithObjects:@"45 x 2",@"76 x 3",@"98 x 3", nil];      

现在我想要所有字符串"x"的字符串到另一个数组.那就是我需要一个包含@"2",@"3",@"3"上述数组元素的数组.

我怎么能实现这个？谢谢..

NSMutableArray *myArray=[[NSMutableArray alloc]initWithObjects:@"45 x 2",@"76 x 3",@"98 x 3", nil];
NSMutableArray *tempArray = [NSMutableArray array];
for(NSString *string in myArray)
{
    NSArray *array = [string componentsSeparatedByString:@"x"];
    if(array.count > 1)
        [tempArray addObject:[array objectAtIndex:1]];
}
