    Hi, I am a new IPhone developer and deal with memory leak.
    I use instruments to find my memory leak.
    This is my code, I know is very ugly. How can I to make it perfect without leak? I know I need to learn much things and thanks for help me.

    NSArray *arr = [NSArray arrayWithObjects:   @"b........b",nil];
    NSMutableArray *chips2D= [self to2DAry:arr];
    	NSMutableArray *returnAry = [[NSMutableArray alloc]init];
    	NSString *str;
    	NSString *str1;
    	NSMutableArray *tempMAry;
    	for (unsigned int i=0; i<[ary count]; i++) {
    		str = [ary objectAtIndex:i] ;
            tempMAry = [[NSMutableArray alloc]init];
    		for (unsigned int j = 0; j<[str length]; j++) {
    			 str1 = [str substringWithRange: NSMakeRange(j, 1)];
    			[tempMAry addObject:str1];
    		[returnAry addObject:tempMAry];
    	return returnAry;

    Did you run Build and Analyze on the code?

    What kind of object leaks?

    What line was it created on?
