Answer 1

UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"警告！" message:@"\n\n\n\n\n\n\n\n\n\n" preferredStyle:UIAlertControllerStyleAlert];

UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleDefault handler:nil];
[alertController addAction:cancelAction];

UIAlertAction *button = [UIAlertAction actionWithTitle:@"确定"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction *action){
//add code to make something happen once tapped
}];

NSMutableAttributedString *hogan = [[NSMutableAttributedString alloc] initWithString:@"Hulk Hogan!"];
[hogan addAttribute:NSForegroundColorAttributeName
value:[UIColor redColor]
range:NSMakeRange(1, 2)];
[alertController setValue:hogan forKey:@"attributedTitle"];

[alertController addAction:button];

[self presentViewController:alertController animated:YES completion:nil];
