简单封装UIAlertController 方便使用

今天看到下面一段代码 ，感觉这代码写的好累🤣🤣🤣。然后就简单的封装一下UIAlertController以方便使用，仅仅只有一个action和两个action的。🤔🤔🤔

原始代码截图

修改后代码如下，是不是看着舒服多了🤓🤓🤓

修改后代码截图

我是给UIViewController添加了一个category，这样只要是UIViewController里都可以直接调用。

代码如下：

#import "UIViewController+AlertVC.h"

@implementation UIViewController (AlertVC)

- (void)presentOneActionAlertControllerTitle:(NSString *_Nullable)aTitle message:(NSString *_Nullable)aMessage actionTitle:(NSString *_Nullable)actionTitle handler:(void (^ _Nullable )(UIAlertAction * _Nullable action))handler {
    UIAlertController *alert = [UIAlertController alertControllerWithTitle:aTitle message:aMessage preferredStyle:UIAlertControllerStyleAlert];
    UIAlertAction *leftAction  = [UIAlertAction actionWithTitle:actionTitle style:UIAlertActionStyleCancel handler:^(UIAlertAction * _Nonnull action) {
        handler(action);
    }];
    [alert addAction:leftAction];
    [self presentViewController:alert animated:YES completion:nil];
}

- (void)presentTwoActionAlertControllerTitle:(NSString *_Nullable)aTitle message:(NSString *_Nullable)aMessage rightTitle:(NSString *_Nullable)rightTitle leftTitle:(NSString *_Nullable)leftTitle rightActionStyle:(UIAlertActionStyle)style rightHandler:(void (^ _Nullable )(UIAlertAction * _Nullable action))rightHandler leftHandler:(void (^ _Nullable )(UIAlertAction * _Nullable action))leftHandler {
    UIAlertController *alert = [UIAlertController alertControllerWithTitle:aTitle message:aMessage preferredStyle:UIAlertControllerStyleAlert];
    UIAlertAction *rightAction  =  [UIAlertAction actionWithTitle:rightTitle style:style handler:^(UIAlertAction * _Nonnull action) {
        rightHandler(action);
    }];
    UIAlertAction *leftAction  = [UIAlertAction actionWithTitle:leftTitle style:UIAlertActionStyleCancel handler:^(UIAlertAction * _Nonnull action) {
        leftHandler(action);
    }];
    [alert addAction:rightAction];
    [alert addAction:leftAction];
    [self presentViewController:alert animated:YES completion:nil];
}

大家一起愉快的Alert弹框吧😉😉😉
