macOS Print result outside of the while loop

[cea]

Hello,

The following example prints out the result line by line in the loop. How can i append the result of each line and print it outside the while loop? Thank you

NSArray * myArray = [NSArray arrayWithObjects:@"One", @"Two", @"Three", nil];
NSEnumerator * myArrayEnumerator = [myArray objectEnumerator];
NSString *thisObject;
while (thisObject = [myArrayEnumerator nextObject])
{
  NSLog(@"thisObject: %@", thisObject);
}
// NSLog(@"Using while loop and I would like the result 
// outside the loop so: thisObject: One Two Three");

Produces:
thisObject: One
thisObject: Two
thisObject: Three

Create an NSMutableString and append the values to it via the appendString: or appendFormat: methods, then just NSLog the mutable string.

I got it. Thank you for your help!

#import "untitled.h"


@implementation untitled
- (IBAction)test:(id)sender{
	NSMutableString *str = [NSMutableString string];
	NSArray * myArray = [NSArray arrayWithObjects:@"One", @"Two", @"Three", nil];
	NSEnumerator * myArrayEnumerator = [myArray objectEnumerator];
	NSString *thisObject;
	while (thisObject = [myArrayEnumerator nextObject]) {
		[str appendString: thisObject];
	}
	NSLog(@"thisObject: %@", str);
}
@end

Result:
thisObject: OneTwoThree
