从NSMutablearray中删除逗号

我从服务器URL获取的结果放到数组中，数组中放了星期对象，但是在获取的时候会得到逗号，我想删除这些逗号然后可以比较。不知道应该怎么做？

array3:
(
{
    Code = "Sunday,";
},
{
    Code = "Thursday,";
},
{
    Code = "Friday,";
},
{
    Code = "Saturday,";
}
)

比较:

NSMutableArray *yourArray = [[NSMutableArray alloc] init];
    for (NSDictionary *dict in array3) {
        [yourArray addObject:[dict valueForKey:@"Code"]];

    }
    BOOL isTheObjectThere = [yourArray containsObject:@"Thursday"];

但是系统会报出isTheObjectThere 'NO' 错误因为得到数组如下:

(
Sunday,,
Thursday,,
Friday,,
Saturday,
)

解决方案

试试：

  for (NSDictionary *dict in array3) {

             NSString *str=[dict valueForKey:@"Code"];

  NSString*newstr=  [str stringByReplacingOccurrencesOfString:@"," withString:@""];

    [yourArray addObject:newstr];

}

这里 有个类似的问题，刚解答不久－ －！希望对你游泳

解决方案三：

用stringByReplacingOccurrencesOfString:

NSMutableArray *newArrayDays = [NSMutableArray array];
for(int i=0; i< [mutArrDays count]; i++) //your array of days here to remove commas from it
{
    [newArrayDays addObject:[[mutArrDays objectAtIndex:i]stringByReplacingOccurrencesOfString@",," withString:@","]:
}

另外你还可以用replaceObjectAtIndex:withObject:
