自己封裝了的AlertController_ZenDei技術網路在線

一直覺得使用系統這個東西寫起來特別麻煩，每次都要寫一大推東西，還是重覆的，今天抽了點時間自己重新封裝了一下，解決了自己的強迫症。。。，不多說，直接上代碼了。 1.自己定義了一個名為XBZ的UIAlertViewControllerde 分類，.h文件裡面 2.然後是.m文件 3.調用方法，就統一寫到 ...

一直覺得使用系統這個東西寫起來特別麻煩，每次都要寫一大推東西，還是重覆的，今天抽了點時間自己重新封裝了一下，解決了自己的強迫症。。。，不多說，直接上代碼了。

1.自己定義了一個名為XBZ的UIAlertViewControllerde 分類，.h文件裡面

 1 #import <UIKit/UIKit.h>
 2 
 3 typedef void(^ActionOne)(void);
 4 
 5 typedef void(^ActionTwo)(void);
 6 
 7 @interface UIAlertController (XBZ)

2.然後是.m文件

  1 #import "UIAlertController+XBZ.h"
  2 
  3 NSTimeInterval kDefaultTimerInterval = 2.f;
  4 
  5 @implementation UIAlertController (XBZ)

 50             break;
 51         case 1:

 70                 }
 71             }]];
 72         }
 73             break;
 74         default:

 95             [alertController addAction:[UIAlertAction actionWithTitle:titles.firstObject style:style handler:^(UIAlertAction * _Nonnull action) {
 96                 if (actionOne) {

136 
137     [timer invalidate];
138     timer = nil;
139 }
140 
141 @end

3.調用方法，就統一寫到一個方法裡面了~

 1 - (void)example {
 2     
 3     [UIAlertController alertWithController:self title:@"這是我的標題，我會自動2s消失"];
 4     
 5     [UIAlertController alertWithController:self title:@"這是我的標題，我會根據時間來讓我消失" timeInterval:4.f];
 6     
 7     [UIAlertController alertWithController:self title:@"我是帶message的，我會自動2s消失" message:@"我是message"];
 8     
 9     [UIAlertController alertWithController:self title:@"我是帶message的，我根據時間來讓我消失" message:@"我是message" timeInterval:3.f];
10     
11     [UIAlertController alertWithController:self title:@"我是帶按鈕的，使用預設風格的action style" message:@"我還是個消息" actionTitles:@[@"確定", @"取消"] actionOne:^{
12         
13         NSLog(@"點了確定了");
14         
15     } actionTwo:^{
16         
17         NSLog(@"點了取消了");
18         
19     } alertStyle:UIAlertControllerStyleAlert];
20     
21     [UIAlertController alertWithController:self title:@"我是帶按鈕的，能自定義action style的" message:@"我就是個消息" actionTitles:@[@"確定", @"取消"] actionStyles:@[@(UIAlertActionStyleDefault), @(UIAlertActionStyleDestructive)] actionOne:^{
22         
23         NSLog(@"點了確定了");
24         
25     } actionTwo:^{
26         
27         NSLog(@"點了取消了");
28         
29     } alertStyle:UIAlertControllerStyleAlert];
30     
31 }

目前就寫了最多兩個按鈕的情況，代碼也算簡化了不少，看著沒那麼亂了，再多的按鈕就單獨寫吧，反正用得不多。-_-

最後附上demo地址吧：https://github.com/BigKingQY/XBZAlertViewController_Demo.git

寫完才發現，名字裡面多了個view...就不改了...-_-！！
