How to change message's aligment in UIAlertView?

　　When I use UIAlertView,I find the message's textAligment is Center. e.g.,When I write this code:　

    UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:nil
                                                   message:@"this is first line     \nsecondLine should be center"
                                                  delegate:nil
                                         cancelButtonTitle:nil
                                         otherButtonTitles:nil, nil];
[alertView show];

the effect is follow:enter image description here
　　As we see, the text"this is first line" is in the center,but I want to change it to left.I know UILabel can change text's alignment,but I don't know whether can I change it in UIAlertView.

iOS7: For left alignment, you can do this:

NSArray *subViewArray = alertView.subviews;
for(int x = 0; x < [subViewArray count]; x++){

    //If the current subview is a UILabel...
    if([[[subViewArray objectAtIndex:x] class] isSubclassOfClass:[UILabel class]]) {
        UILabel *label = [subViewArray objectAtIndex:x];
        label.textAlignment = NSTextAlignmentLeft;
    }
}

Or you can add an UILabel to alertView:

    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Centered Title" message:@"\n\n\n" delegate:self cancelButtonTitle:@"Close" otherButtonTitles:nil];

    UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(12.0, 24.0, 250.0, 80.0)];
    label.numberOfLines = 0;
    label.textAlignment = NSTextAlignmentLeft;
    label.backgroundColor = [UIColor clearColor];
    label.textColor = [UIColor whiteColor];
    label.text = @"Here is an example of a left aligned label in a UIAlertView!";
    [alert addSubview:label];
    [alert show];

Edit your code like this.

UIAlertView *alert = [[UIAlertView alloc]initWithTitle:nil
                                               message:nil
                                              delegate:nil
                                     cancelButtonTitle:nil
                                     otherButtonTitles:nil, nil];


UILabel *v = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 80, 40)];
v.text = NSTextAlignmentLeft;
v.numberOfLines = 0;
v.text = @"this is first line\nsecondLine should be center";
[alert setValue:v forKey:@"accessoryView"];
[alert show];
