NSMutableArray*array = [[NSMutableArray alloc] initWithObjects:#"a", #"d", #"r", nil];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"msg"
message:[array Description]
delegate:nil
cancelButtonTitle:#"Ok"
otherButtonTitles:nil];
[alert show];
Output should be like
a
d
r
Not like
(a
d
r
)

Answer 1

You can directly use NSString for this purpose.
But if you insist on using NSMutableArray then do something like this.
NSMutableArray *arr = [[NSMutableArray alloc] initWithObjects:#"a",#"b",#"c", nil];
NSString *joinedString = [arr componentsJoinedByString:#" "];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"msg"
message:joinedString
delegate:nil
cancelButtonTitle:#"Ok"
otherButtonTitles:nil];
[alert show];

Answer 2

You are sending an NSArray description to an NSString parameter. This is where the braces come from. If you send a description message to an array, you will get back a string with all objects in an array enclosed with 'your' braces.
I am not sure what are you actually trying to achieve here. Message should be an NSString object like #"Invalid input".
If you want output a d r, I would combine objects of array into single string:
NSMutableArray*array = [[NSMutableArray alloc] initWithObjects:#"a", #"d", #"r", nil];
NSString *combinedString = [NSString stringWithFormat:#"%# %# %#", array[0], array[1], array[2]];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"msg"
message:combinedString
delegate:nil
cancelButtonTitle:#"Ok"
otherButtonTitles:nil];
[alert show];
