我遇到NSMutableArray问题并通过containsObject

查找对象

我有一个看起来像这样的数组：

NSMutableArray serverValue（ 168,169,170,171,172,173,174,175,176,177,178,179,180,181,180,179,178,177,176,175,174,173,172,171,170,171,172,173,174,175,176,177,178,179,180,181,182,183，从服务器获取的184,185,186,187,188,189,190,191,192,193,194（这是Xcode转储）

我正在尝试找到0到359之间的所有值，这些值不在上面的数组中。

int index;
NSMutableArray *not = [NSMutableArray arrayWithCapacity:10];
  for (index = 0; index < 360; index++) {
      if (! [serverValue containsObject:[[NSNumber numberWithInt:index] stringValue]]) {
          [not addObject:[[NSNumber numberWithInt:index] stringValue]];
      }
  }

我希望新数组的值为0-167和194-359，但我得到：

＆lt; __ NSArrayM 0xc92de80＆gt;（ 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24， 25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49， 50， 51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75， 76,77,78,79,80,81,82,83,84,85,86,87,88,89,90,91,92,93,94,95,96,97,98,99,100， 101,102,103,104,105,106,107,108,109,110,111,112,113,114,115,116,117,118,119,120,121,122,123,124,125， 126,127,128,129,130,131,132,133,134,135,136,137,138,139,140,141,142,143,144,145,146,147,148,149,150,151,152,153,154,155,156,157,158,159,160,161,162,163， 164165166167，

168,169,185,187,188,189,191,193，

194,195,196,197,198,199,200,201,202,203,204,205,206,207,208,209,210,211,212,213,214,215,216,217,218,219， 220,221,222,223,224,225,226,227,228,229,230,231,232,233,234,235,236,237,238,239,240,241,242,243,244,245,246,247,248,249,250,251,252,253,254,255,256,257， 258,259,260,261,262,263,264,265,266,267,268,269,270,271,272,273,274,275,276,277,278,279,280,281,282,283,284,285,286,287,288,289,290,291,292,293,294， 295,296,297,298,299,300,301,302,303,304,305,306,307,308,309,310,311,312,313,314,315,316,317,318,319,320,321,322,323,324,325,326,327,328,329,330,331， 332,333,334,335,336,337,338,339,340,341,342,343,344,345,346,347,348,349,350,351,352,353,354,355,356,357,358,359）（这是一个Xcode转储）

为什么只是serverValue数组中的一些值？任何想法我做错了什么？

欢呼，

不要与字符串值进行比较。看起来serverValue的整数不是字符串值

for (index = 0; index < 360; index++) {
    if (! [serverValue containsObject:[NSNumber numberWithInt:index]]) {
        [not addObject:[[NSNumber numberWithInt:index] stringValue]];
    }
}

如果数组包含字符串和数字

，也可以尝试这样做

for (index = 0; index < 360; index++) {
    BOOL isNeedToAdd = NO;
    if (![serverValue containsObject:[NSNumber numberWithInt:index]] &&
        ![serverValue containsObject:[[NSNumber numberWithInt:index]stringValue]]) {
        isNeedToAdd = YES;
    }

    if (isNeedToAdd) {
        [not addObject:[[NSNumber numberWithInt:index] stringValue]];
    }
}

此代码将查看值是以数字还是字符串形式存在。如果两者都不存在，则将其添加到结果中。
