实现对UIAlertController和UIAlertView判断系统后的简单封装

iOS8之后用UIAlertController代替了UIAlertView,所以每次有需要弹窗的时候,都需要先判断系统,最近在做的项目中弹窗较多,如果每次都判断,真是太麻烦了,索性对UIAlertController和UIAlertView进行的封装了,封装在一个工具类中,在工具类中就对系统进行判断,然后在你需要弹窗的界面直接调用这个工具类的方法就可以了,减少了代码的耦合.

这个工具类其实也封装的特别简单,因为都是用的系统的,分享出来给大家参考下:

首先是.h文件

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

只有这么一个简单的方法 把你需要在弹窗中显示的内容以参数的形式传入就可以了

然后是.m文件的实现

#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==0) {
confirmParam();
}
else{
cancleParam();
}
}
@end
