Convert NSArray to NSString in Objective-C

NSString * result = [[array valueForKey:@"description"] componentsJoinedByString:@""];

One approach would be to iterate over the array, calling the description message on each item:

NSMutableString * result = [[NSMutableString alloc] init];for (NSObject * obj in array){    [result appendString:[obj description]];}NSLog(@"The concatenated string is %@", result);

Another approach would be to do something based on each item's class:

NSMutableString * result = [[NSMutableString alloc] init];for (NSObject * obj in array){    if ([obj isKindOfClass:[NSNumber class]])    {        // append something    }    else    {        [result appendString:[obj description]];    }}NSLog(@"The concatenated string is %@", result);

If you want commas and other extraneous information, you can just do:

NSString * result = [array description];

I think Sanjay's answer was almost there but i used it this way

NSArray *myArray = [[NSArray alloc] initWithObjects:@"Hello",@"World", nil];NSString *greeting = [myArray componentsJoinedByString:@" "];NSLog(@"%@",greeting);

Output :

2015-01-25 08:47:14.830 StringTest[11639:394302] Hello World

As Sanjay had hinted - I used method componentsJoinedByString from NSArray that does joining and gives you back NSString

BTW NSString has reverse method componentsSeparatedByString that does the splitting and gives you NSArray back .
