How to convert NSNumber to NSString

Question

So I have an NSArray \"myArray\" with NSNumbers and NSStrings. I need them in another UIView so i go like this:

Answer 1

The funny thing is that NSNumber converts to string automatically if it becomes a part of a string. I don't think it is documented. Try these:

NSLog(@"My integer NSNumber:%@",[NSNumber numberWithInt:184]);
NSLog(@"My float NSNumber:%@",[NSNumber numberWithFloat:12.23f]);
NSLog(@"My bool(YES) NSNumber:%@",[NSNumber numberWithBool:YES]);
NSLog(@"My bool(NO) NSNumber:%@",[NSNumber numberWithBool:NO]);

NSString *myStringWithNumbers = [NSString stringWithFormat:@"Int:%@, Float:%@ Bool:%@",[NSNumber numberWithInt:132],[NSNumber numberWithFloat:-4.823f],[NSNumber numberWithBool:YES]];
NSLog(@"%@",myStringWithNumbers);

It will print:

My integer NSNumber:184
My float NSNumber:12.23
My bool(YES) NSNumber:1
My bool(NO) NSNumber:0
Int:132, Float:-4.823 Bool:1

Works on both Mac and iOS

This one does not work:

NSString *myNSNumber2 = [NSNumber numberWithFloat:-34512.23f];

Answer 2

In Swift you can do like this

let number : NSNumber = 95
let str : String = number.stringValue

Answer 3

Try:

NSString *myString = [NSNumber stringValue];

Answer 4

You can do it with:

NSNumber *myNumber = @15;
NSString *myNumberInString = [myNumber stringValue];

Answer 5

or try NSString *string = [NSString stringWithFormat:@"%d", [NSNumber intValue], nil];

Answer 6

In Swift 3.0

let number:NSNumber = 25
let strValue = String(describing: number as NSNumber)
print("As String => \(strValue)")

We can get the number value in String.
