I have this code which created with UITableView and making the cell’s color show alternatively white and grey. Capture

How can I correct this, without memory leak? Thanks!

    Your code is:

    cell.backgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"bg_white.png"]];

    This leaks the UIImageView. You allocated it, but you didn’t release it afterwards.

    To fix:

    UIImageView* imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"bg_white.png"]]; 
cell.backgroundView = imageView;
[imageView release];

    The arrows in the analyzer warning are a little misleading — they’re trying to show the flow of the execution through the code, into the method that caused the leak, and then out. The textual messages are the important part.

    (Also, I suspect you want tbl_RowIndex1 % 2, not tbl_RowIndex1 %= 2.)
