Question

I am trying to concatenate the contents of an NSMutableArray using

NSString* result = @""; 

for(NSString* test in  self.selectedOnes) {

    NSLog(test) ; 
    [result stringByAppendingString:test];
    [result stringByAppendingString:@","];
}

but result remains @"", I am sure that the selectedOnes contains data because it writes to the log.

Any suggestions?

Answer 1

stringByAppendingString: returns a new String.

This should work.

NSString* result = @""; 

for(NSString* test in  self.SelectedOnes  )
{
    NSLog( test ) ; 
    result = [result stringByAppendingString:test];
    result = [result stringByAppendingString:@","];
}
