Convert NSArray to NSString in Objective-C

Question

I am wondering how to convert an NSArray [@\"Apple\", @\"Pear \", 323, @\"Orange\"] to a string in Objective-C.

Answer 1

Swift 3.0 solution:

let string = array.joined(separator: " ")

Answer 2

The way I know is easy.

var NSArray_variable = NSArray_Object[n]
var stringVarible = NSArray_variable as String

n is the inner position in the array This in SWIFT Language. It might work in Objective C

Answer 3

NSArray *array = [NSArray arrayWithObjects:@"One",@"Two",@"Three", nil];
NSString *stringFromArray = [array componentsJoinedByString:@" "];

The first line initializes an array with objects. The second line joins all elements of that array by adding the string inside the "" and returns a string.

Answer 4

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];

Answer 5

NSString * str = [componentsJoinedByString:@""];

and you have dic or multiple array then used bellow

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

Answer 6

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