直接上代碼 很簡單

    PTLAlertView *alertView = [[PTLAlertView alloc]initWithTitle:@"我是標題" message:@"你好你好嗎哈哈你好嗎哈哈你好嗎哈哈你好嗎哈哈你好嗎哈哈你好嗎哈哈你好嗎哈哈你好嗎哈哈嗎哈哈你好你好嗎哈哈你好嗎哈哈你好嗎哈哈你好嗎哈哈你好嗎哈哈你好嗎哈哈你好嗎哈哈你好嗎哈哈嗎哈哈你好你好嗎哈哈你好你好嗎哈哈你好嗎哈哈你好嗎哈哈你好嗎哈哈你好嗎哈哈你好嗎哈哈你好嗎哈哈你好嗎哈哈嗎哈哈" cancelButtonTitle:@"取消" otherButtonTitles:@"確定",@"等一會", nil];
    
    [alertView setSelctBtnBlock:^(NSInteger index, NSString * _Nullable btnCurrentTitle) {
        NSLog(@"hha- %zd ---- %@", index, btnCurrentTitle);
    }];
    
// 修改屬性
//    alertView.titleBackgroundColor = [UIColor redColor];
//    alertView.titleTextColor = [UIColor greenColor];
//    alertView.titleTextFont = [UIFont systemFontOfSize:20];
//    alertView.messageTextColor = [UIColor redColor];
//    alertView.messageTextFont = [UIFont systemFontOfSize:15];
    alertView.cancelBtnTextColor = [UIColor redColor];
//    alertView.cancelBtnTextFont = [UIFont systemFontOfSize:20];
//    alertView.otherBtnTextColor = [UIColor yellowColor];
//    alertView.otherBtnTextFont = [UIFont systemFontOfSize:20];
    
    [alertView show];
