Question

所以我在这里涉及三个不同的阵列......

我正在循环通过golferThreeIcons（NSMutableArray），我正在尝试取得最高的4个结果（golferThreeIcons包含#'s作为字符串）并将它们存储到topFourIconsNum（NSMutableArray）中然后我计划存储id数组topFourIconsId（NSMutableArray）中最高数字的数字。

一个棘手的事情是，golferThreeIcons从99开始，但我希望它能像零一样行动。所以数字99不应该被添加到任何一个数组......

实施例： golferThreeIcons {2,1,5,3,9}

循环结束后，我希望它显示出类似的东西......

topFourIconsId {0,2,3,4} --- 0对应于golferThreeIcons中的2 --- 2对应于高尔夫球手中的5个三个图标

topFourIconsNum {2,5,3,9} ----（任何顺序，只要它对应前四个图标id）

NSMutableArray *topFourIconsId = [NSMutableArray arrayWithObjects: @"0", @"0", @"0", @"0", @"0" ,nil];
NSMutableArray *topFourIconsNum = [NSMutableArray arrayWithObjects: @"0", @"0", @"0", @"0", @"0" ,nil];
int *ids = 0;
                for (NSString *s in golferThreeIconCounter) {
                    if(s != @"0") {
                        int sint = [s intValue];
                        int *idn = 0;
                        for(NSString *n in topFourIconsNum) {
                            int nint= [n intValue];
                            if(sint == 99 && nint == 0) {
                                NSString *idstring = [NSString stringWithFormat:@"%d", ids];
                                NSString *sintstring = [NSString stringWithFormat:@"%d", sint];
                                [topFourIconsId replaceObjectAtIndex:idn withObject:idstring];
                                [topFourIconsNum replaceObjectAtIndex:idn withObject:sintstring];
                                NSLog(@"IN %@",sintstring);
                                break;
                            }
                            else {
                                if (sint > nint) {
                                    NSString *idstring = [NSString stringWithFormat:@"%d", ids];
                                    NSString *sintstring = [NSString stringWithFormat:@"%d", sint];
                                    [topFourIconsId replaceObjectAtIndex:idn withObject:idstring];
                                    [topFourIconsNum replaceObjectAtIndex:idn withObject:sintstring];
                                    NSLog(@"IN %@",sintstring);
                                    break;
                                }
                            }
                            idn++;
                        }
                    }
                    ids++;
                }

只是一个疯狂的想法

将golferThreeIcons放在NSDictionary中，数组索引为键，数组值为值，然后按键对值进行排序：

NSDictionary *dict = [NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:@"2", @"1", @"5", @"3", @"9", nil] forKeys:[NSArray arrayWithObjects:@"0", @"1", @"2", @"3", @"4", nil]];
NSArray *sortedKeys = [dict keysSortedByValueUsingSelector:@selector(caseInsensitiveCompare:)];

NSLog([sortedKeys description]);

阵列＃1中最高的4个数字存储在另一个阵列中
