Question

I’m trying to iterate through an NSArray and keep getting a compiler error right when i try concatenating the contents of my array at position i to my NSMutableString instance..

It just tells me that there’s a ‘syntax error before ;’ which doesn’t tell me a whole lot. at this line:

  [output appendString:[widget.children objectAtIndex:i];  

i know there must be something up with my syntax..

my function is as follows

- (NSString *)readArray {     NSMutableString *output = [[NSMutableString alloc] init];     int i;     int arraySize = widget.children.count;     NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];     for (i = 0; i < arraySize; i++)     {         [output appendString:[widget.children objectAtIndex:i];  (throws error here)     }     [pool release];     return output;  } 

thanks in advance

Answer 1

you have an unclosed bracket
you need ]] at the end instead of ]
