Question

In my application NSMutableArray comes like this,

 Activity:(
"0-1",
"2-4",
"3-5",
"1-2"
)

I want data in NSMutableArray Like,

Activity:(
"1",
"4",
"5",
"2"
)

Please, Any one suggest me how can i do that?

First of all I agree with Richard’s comment.
Also, it’s a bad habit naming your ivars capitalized.
That said, you can accomplish what you need with something like this:

NSMutableArray *cleanArray = [[NSMutableArray alloc] initWithCapacity:0];  

// Here 'Activity' is your NSArray. A better name would be 'activity'
// (save capitalized names for classes)
for (NSString *item in Activity)
{
    [cleanArray addObject:[[item componentsSeparatedByString:@"-"] lastObject]];
}

And now you got an array with the substrings after the ‘-‘ so you could just replace your original array with the new one.
