在我的应用程序中，我必须获取特定对象的索引值。为此，我以这种方式编码，如下所示。

NSString *a=[NSString stringWithFormat:@"%d",[imagesdmobject.proofID intValue]];
NSLog(@"a value is %@",a);

这里的值为 56 现在我必须从中获取 56 的索引appdelegate.projectTitlesProofIDArray。

int value=[appdelegate.projectTitlesProofIDArray indexOfObjectIdenticalTo:a];

中的数据appdelegate.projectTitlesProofIDArray是：

41, 34, 35, 64, 45, 1, 67, 75, 76, 77, 78, 79, 80, 81, 82, 83, 85, 68, 86, 87, 88, 89, 90, 92, 69, 95, 97, 98, 100, 101, 70, 71, 72, 73, 74, 39, 37, 109, 108, 110, 38, 91, 93, 94, 36, 96, 99, 102, 103, 104, 105, 106, 107, 65, 66, 40, 46, 47, 48, 49, 50, 52, 53, 54, 60, 61, 62, 32, 55, 56, 57, 58, 59, 42, 43, 44, 63, 47, 48, 41, 34, 35, 64, 1, 91, 93, 94, 36, 96, 99, 102, 103, 104, 105, 106, 107, 65, 66, 40, 60, 61, 62, 32, 55, 56, 57,58, 59, 54, 34, 35, 41, 34, 35, 64, 67, 75, 76, 77, 78, 79, 80, 81, 82, 83, 85, 68, 86, 87, 88, 89, 90, 92, 69, 95, 97, 98, 100, 101, 70, 71, 72, 73, 74, 39, 37, 109, 108, 110, 38, 91, 93, 94, 36, 96, 99, 102, 103, 104, 105, 106, 107, 65, 66, 40, 46, 47, 48, 49, 50, 52, 53, 54, 41, 34, 35, 64, 45, 1, 67, 75, 76, 77, 78, 79, 80, 81, 82, 83, 85, 68, 86, 87, 88, 89, 90, 92, 69, 95, 97, 98, 100, 101, 70, 71, 72, 73、74、39、37、109、108, 110, 38, 91, 93, 94, 36, 96, 99, 102, 103, 104, 105, 106, 107, 65, 66, 40, 46, 47, 48, 49, 50, 52, 53, 54, 60, 61, 62, 32, 55, 56, 57, 58, 59, 42, 43, 44, 47, 34, 35, 39, 37, 109, 108, 110, 38, 46, 47, 48, 49, 50, 52, 53, 54, 42, 43, 44, 41, 34, 35, 64, 45, 1, 67, 75, 76, 77, 78, 79, 80, 81, 83, 85, 68, 86, 87, 88, 89, 90, 92, 69, 95, 97, 98, 100, 70, 71, 73, 74, 39, 37, 109, 108, 110, 38, 91, 94, 36, 96, 99, 102, 103, 104, 105,106, 107, 65, 66, 40, 46, 47, 48, 49, 50, 52, 54, 60, 61, 62, 32, 55, 56, 57, 58, 59, 42, 43, 63, 41, 34, 35, 64, 45, 1, 67, 75, 76, 77, 78, 79, 80, 81, 82, 83, 85, 68, 86, 87, 88, 89, 90, 92, 69, 95, 97、98、100、101、70、71、72、73、74、39、37、109、108、110、38、91、93、94、36、96、99、102、103、104、105、 106, 107, 65, 66, 40, 46, 47, 48, 49, 50, 52, 53, 54, 60, 61, 62, 32, 55, 56, 57, 58, 59, 42, 43, 44, 63, 41, 34, 35, 64, 45,1, 67, 75, 76, 77, 78, 79, 80, 81, 82, 83, 85, 68, 86, 87, 88, 89, 90, 92, 69, 95, 97, 98, 100, 101, 70, 71, 72, 73, 74, 39, 37, 109, 108, 110, 38, 91, 93, 94, 36, 96, 99, 102, 103, 104, 105, 106, 107, 65, 66, 40, 46, 47, 48, 49, 50, 52, 53, 54, 60, 61, 62, 32, 55, 56, 57, 58, 59, 42, 43, 44, 63, 46108, 110, 38, 91, 93, 94, 36, 96, 99, 102, 103, 104, 105, 106, 107, 65, 66, 40, 46, 47, 48, 49, 50, 52, 53, 54, 60, 61, 62, 32, 55, 56, 57, 58, 59, 42, 43, 44, 63, 46108, 110, 38, 91, 93, 94, 36, 96, 99, 102, 103, 104, 105, 106, 107, 65, 66, 40, 46, 47, 48, 49, 50, 52, 53, 54, 60, 61, 62, 32, 55, 56, 57, 58, 59, 42, 43, 44, 63, 46

56 在那里，但我得到的值不正确，为 2147483647。

请在这个问题上帮助我。我被困在这个地方。

你需要这样做：-

假设您的数组包含：-

[array addObject:@"1"];
[array addObject:@"2"];
[array addObject:@"3"];
[array addObject:@"4"];
[array addObject:@"5"];
[array addObject:@"6"];

现在你需要找到对象 5 的索引

if([array containsObject:@"5"])
{
int index=[array indexOfObject:@"5"];
}
