获取正确的字典索引

Question

    NSMutableArray *tmpMutArr = [NSMutableArray arrayWithArray:allObjectsArray];
    NSLog(@"The content of array is%@",tmpMutArr);

    int index;

     for (int i=0;i<[tmpMutArr count];i++) 
     {
     if([[tmpMutArr  objectAtIndex:i] isKindOfClass:[NSDictionary class]])
     {
     NSMutableDictionary *tempDict = [tmpMutArr  objectAtIndex:i];
         if([[tempDict valueForKey:@"Name"] isEqualToString:[NSString stringWithFormat:@"%@", nameString]])
     {
     index = i;

     }
     }
     }

     [tmpMutArr replaceObjectAtIndex:index withObject:[NSDictionary dictionaryWithDictionary:mutDict]];

此代码不会像我想要的那样替换tmpMutArr中的匹配对象,而是替换tmpMutArr中的所有对象.如何只替换我想要的索引？

我知道tmpMutArr在替换之前包含所有对象,所以我只需要正确指定索引.怎么办？

NSMutableArray *tmpMutArr = [NSMutableArray arrayWithArray:allObjectsArray];
NSLog(@"The content of array is%@",tmpMutArr);

int index;

for (int i=0;i<[tmpMutArr count];i++) 
{
    if([[tmpMutArr  objectAtIndex:i] isKindOfClass:[NSDictionary class]])
    {
        NSMutableDictionary *tempDict = [tmpMutArr  objectAtIndex:i];
        if([[tempDict valueForKey:@"Name"] isEqualToString:nameString])
        {
            index = i;
            break; // << added break
        }
    }
}

[tmpMutArr replaceObjectAtIndex:index withObject:[NSDictionary dictionaryWithDictionary:mutDict]];
