为什么此alertView代码不起作用？ 没有错误，只是没有做应该做的

Question

-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
    NSLog(@"buttonindex: %i", buttonIndex);
    NSLog(@"tag: %i", alertView.tag);
    if ((alertView.tag <= 3) && (alertView.tag >= 1)) {

    } //Between 1 and 3
    else if (alertView.tag = 8) {

        }
    else if (alertView.tag = 10) {
        NSLog(@"Test");

    }
}

For some reason, even though i'm using alertView with tag 10, and it's returning "Tag: 10" on the NSLog, it isn't showing the "Test" log, or processing any code from within those last brackets. And yet alertView tag 8 is working fine.

Be careful, it should be == in your if statements. Apart from that, how do you assign tags to the alertviews?
