基于UIAlertController的封装调用

UIAlertController是iOS8之后推出的合并UIAlert和UIActionSheet的控件，我相信很多地方都会使用到的，因此在一个单例中对其进行封装一下，每次使用时不必再写那么重复的代码，如下：

单例.h文件中

#pragma mark 显示ios默认样式的confrim框(基于UIAlertController)
    /**
     *  @author zm
     *
     *  @brief 显示ios默认样式的confrim框(基于UIAlertController)
     *
     *  @param title          标题
     *  @param message        内容
     *  @param confirmHandler confirm的block
     *  @param confirmTitle   confirm的标题
     *  @param cancelHandler  cancel的block
     *  @param cancelTitle    cancel的标题
     *  @param target         加载对象
     */
    - (void)f_showConfirm_default_title:(NSString *)title message:(NSString *)message confirmHandler:(void (^)(UIAlertAction *action))confirmHandler  confirmTitle:(NSString *)confirmTitle cancelHandler:(void (^)(UIAlertAction *action))cancelHandler  cancelTitle:(NSString *)cancelTitle target:(UIViewController *)target;

单例.m文件中

#pragma mark 显示ios默认样式的confrim框(基于UIAlertController)
    - (void)f_showConfirm_default_title:(NSString *)title message:(NSString *)message confirmHandler:(void (^)(UIAlertAction *action))confirmHandler  confirmTitle:(NSString *)confirmTitle cancelHandler:(void (^)(UIAlertAction *action))cancelHandler  cancelTitle:(NSString *)cancelTitle target:(UIViewController *)target
    {
        UIAlertController *_alertC_temp = [UIAlertController alertControllerWithTitle:title message:message preferredStyle:UIAlertControllerStyleAlert];
        UIAlertAction *_alertAct_cancel = [UIAlertAction actionWithTitle:cancelTitle style:UIAlertActionStyleCancel handler:cancelHandler];
        [_alertC_temp addAction:_alertAct_cancel];
        UIAlertAction *_alertAct_confirm = [UIAlertAction actionWithTitle:confirmTitle style:UIAlertActionStyleDefault handler:confirmHandler];
        [_alertC_temp addAction:_alertAct_confirm];
        [target presentViewController:_alertC_temp animated:YES completion:nil];
    }

调用时

__weak __typeof(self) weakSelf = self;
        void(^confirmHandler)(UIAlertAction *action) = ^(UIAlertAction *action) {
            [[weakSelf 方法];
        };
        void(^cancelHandler)(UIAlertAction *action) = ^(UIAlertAction *action) {
            XNLog(@"我是cancel回调");
        };
        [[xn_base_Handler_Alert_HUD sharedInstance] f_showConfirm_default_title:@"" message:@"确定取消订单吗？" confirmHandler:confirmHandler confirmTitle:@"确定" cancelHandler:cancelHandler cancelTitle:@"取消" target:self];

这是对一个最基本的含有@“确定”、@“取消”按钮进行的简单封装，如想添加text等或只要确定、取消其中的一个按钮，均可在此基础上进行修改。
