Iphone 如何将可变数组的最后三个数据与字符串进行比较？

在我的应用程序中，我得到了可变数组中的数据，如下所示

   MutableArray1:(
       "22.298166 , 73.165809",
       "22.300598 , 73.167183",
       "22.298101 , 73.166188",
       "22.298128 , 73.166194"
       "22.298130 , 73.166194"
      )

我想将数据为“22.298130，73.166194”的NSString与可变数组1的最后三个数据进行比较

请告诉我怎么做？

if（[Array1 count]>3）
        if([Array1 count]>3)
        {
           for (int i = [Array1 count] - 4; i < [Array1 count]; i++) {
                if ([[Array1 objectAtIndex:i] isEqualToString:@"22.298130 , 73.166194"]) {
                    NSLog (@"True");
                    //Write your Code Here
                }
            }
        }

{
for（int i=[Array1 count]-4；i<[Array1 count]；i++）{
if（[[Array1 objectAtIndex:i]IsequalString:@“22.298130,73.166194”]）{
NSLog（@“真”）；
//在这里编写代码
}
}
}

如果您只需要知道它是否在阵列中：

NSString *searchString = @"22.298130 , 73.166194";    
BOOL found = [[array subarrayWithRange:NSMakeRange([array count]-3, 3)] containsObject:searchString];
NSLog(@"%@", (found) ? @"YES" : @"NO");

如果你需要知道索引，你可以这样做

[[array subarrayWithRange:NSMakeRange([array count]-3, 3)] enumerateObjectsUsingBlock:^(NSString  *obj, NSUInteger idx, BOOL *stop) {
    if ([obj isEqualToString:searchString]) {
        *stop = YES; //avoid further loops, if we had a positive hit.
         NSLog(@"%lu %lu", idx, [array count]-3+idx);  //index in subarray and in original array
    };
}];

[[array subarrayWithRange:NSMakeRange([array count]-3, 3)] enumerateObjectsUsingBlock:^(NSString  *obj, NSUInteger idx, BOOL *stop) {
    if ([obj isEqualToString:searchString]) {
        *stop = YES; //avoid further loops, if we had a positive hit.
         NSLog(@"%lu %lu", idx, [array count]-3+idx);  //index in subarray and in original array
    };
}];
