UIAlertController UIAlertView用法

项目中很多地方会出现弹出框框，来做个判断

基本方法如下

UIAlertController *alertC = [UIAlertController alertControllerWithTitle:@"友情提示" message:@"是否确定退出程序" preferredStyle:UIAlertControllerStyleAlert];

UIAlertAction *cancelA = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:^(UIAlertAction *action) {

}];

UIAlertAction *configA = [UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {

//执行的代码

}];

}];

[alertC addAction:cancelA];

[alertC addAction:configA];

[self presentViewController:alertC animated:YES completion:nil];

因为很多地方都要用到，每次写太麻烦了 ，简单封装一下成为一个工具，提高，，，

1. 创建一个TOOl继承于NSObject

@interface UIAlertTool : NSObject

- (void)initshowAlertView:(UIViewController *)viewController title:(NSString *)title message:(NSString *)message cancel:(NSString        *)cancelButtonTitle other:(NSString *)otherButtonTitle confirmHandle:(void (^)())confirm cancelHandle:(void (^)())cancle;

@end

2.实现部分

#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)initshowAlertView:(UIViewController *)viewController title:(NSString *)title message:(NSString *)message cancel:(NSString *)cancelButtonTitle other:(NSString *)otherButtonTitle confirmHandle:(void (^)())confirm cancelHandle:(void (^)())cancle

{ confirmParam = confirm;

cancleParam = cancle;

if (IAIOS8) {

UIAlertController *alertController = [UIAlertController alertControllerWithTitle:title message:message preferredStyle:UIAlertControllerStyleAlert];

UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:cancelButtonTitle style:UIAlertActionStyleCancel handler:^(UIAlertAction *action) {

cancle();

}];

UIAlertAction *otherAction = [UIAlertAction actionWithTitle:otherButtonTitle style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {

confirm();

}];

[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
