How to convert NSArray to NSString

Question

How to convert NSArray to NSString in objective-c?

Answer 1

Whereas you are not saying that in NSArray, you can do this:

NSArray *arr = [NSArray arrayWithObjects: @"foo", @"bar", @"baz"]; [arr componentsJoinedByString: @","] 

Answer 2

Unlike Frank's method, which works very well, you can also do

 NSString *myArrayString = [array description]; 

By default, the NSArray implementation will print the contents in neatly formatted form.

Answer 3

This is how I converted my NSArray to NSString

 NSError *error = nil; NSData *data = [NSJSONSerialization dataWithJSONObject:aArray options:kNilOptions error:&error]; NSString *str = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; 

Answer 4

Latest Swift 3.0 Updates

let string = array.componentsJoined(by: ",")

you can use any separator in the function that you want to separate from the array elements in the above example - ",".
