An elegant solution would be this:

NSMutableString *str; //your string here
NSArray *newArray = @[str];

Using the new notation, it's a piece of cake.

// You must use NSMutableArray to add Object to array

NSMutableArray *tableCellNames;
// arrayWithCapacity is a required parameter to define limit of your object.
tableCellNames = [NSMutableArray arrayWithCapacity:total_rows];

[tableCellNames addObject:title];
NSLog(@"Array table cell %@",tableCellNames);

If you want to instantiate an NSArray with a single NSMutableString object, you can do the following:

NSString *myString; //Assuming your string is here
NSArray *array = [NSArray arrayWithObjects:myString,nil];

Note that NSArray will be immutable - that is, you can't add or remove objects to it after you've made it. If you want the array to be mutable, you'll have to create an NSMutableArray. To use an NSMutableArray in this fashion, you can do the following:

NSString *myString; //Assuming your string is here
NSMutableArray *array = [[NSMutableArray alloc] init];
[array addObject:myString];

Actually, Mike is wrong. If you want to instantiate an NSArray with a single NSMutableString object, you can do the following:

NSMutableString *myString; //Assuming your string is here
NSArray *array = [NSArray arrayWithObject:myString];

There is no arrayWithElements in NSArray (see NSArray documentation)

NSArray is immutable, so you cannot add values to it. You should use NSMutableArray in order to do that with the addObject: method.

NSMutableString *str = ...
NSMutableArray *array = [[NSMutableArray alloc] init];
[array addObject:str];
