實作對UIAlertController和UIAlertView判斷系統後的簡單封裝

實作對UIAlertController和UIAlertView判斷系統後的簡單封裝

iOS8之後用UIAlertController代替了UIAlertView,是以每次有需要彈窗的時候,都需要先判斷系統,最近在做的項目中彈窗較多,如果每次都判斷,真是太麻煩了,索性對UIAlertController和UIAlertView進行的封裝了,封裝在一個工具類中,在工具類中就對系統進行判斷,然後在你需要彈窗的界面直接調用這個工具類的方法就可以了,減少了代碼的耦合.

這個工具類其實也封裝的特别簡單,因為都是用的系統的,分享出來給大家參考下:

首先是.h檔案

[objc] view plaincopy

- @interface UIAlertTool : NSObject
- -(void)showAlertView:(UIViewController *)viewController :(NSString *)title :(NSString *)message :(NSString *)cancelButtonTitle :(NSString *)otherButtonTitle :(void (^)())confirm :(void (^)())cancle;
- @end
           

隻有這麼一個簡單的方法 把你需要在彈窗中顯示的内容以參數的形式傳入就可以了

然後是.m檔案的實作

[objc] view plaincopy

- #define IAIOS8 ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)
- #import "UIAlertTool.h"
- typedef void (^confirm)();
- typedef void (^cancle)();
- @interface UIAlertTool(){
-     confirm confirmParam;
-     cancle  cancleParam;
- }
- @end
- @implementation UIAlertTool
- -(void)showAlertView:(UIViewController *)viewController :(NSString *)title :(NSString *)message :(NSString *)cancelButtonTitle :(NSString *)otherButtonTitle :(void (^)())confirm :(void (^)())cancle{
-     confirmParam=confirm;
-     cancleParam=cancle;
-     if (IAIOS8) {
-
-         UIAlertController *alertController = [UIAlertController alertControllerWithTitle:title message:message preferredStyle:UIAlertControllerStyleAlert];
-
-         // Create the actions.
-         UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:cancelButtonTitle style:UIAlertActionStyleCancel handler:^(UIAlertAction *action) {
-              cancle();
-
-         }];
-
-         UIAlertAction *otherAction = [UIAlertAction actionWithTitle:otherButtonTitle style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
-             confirm();
-         }];
-
-         // Add the actions.
-         [alertController addAction:cancelAction];
-         [alertController addAction:otherAction];
-
-         [viewController presentViewController:alertController animated:YES completion:nil];
-
-     }
-     else{
-         UIAlertView *TitleAlert = [[UIAlertView alloc] initWithTitle:title message:message delegate:self cancelButtonTitle:otherButtonTitle otherButtonTitles:cancelButtonTitle,nil];
-         [TitleAlert show];
-     }
-
- }
-
- -(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
-     if (buttonIndex==) {
-         confirmParam();
-     }
-     else{
-         cancleParam();
-     }
- }
- @end
