由UIAlertController封装的工具类

由于苹果弃用了之前的AlertView，取而代之的是UIAlertController，但UIAlertController写起来代码量却增多了，加之项目中用到提示的地方很多，写起来很麻烦，于是，封装了一个UIAlertController的工具。

#import <Foundation/Foundation.h>

@interface AlertControllerTool : NSObject

//没有取消按钮(确认后无跳转)
+(UIAlertController *)alertMesasge:(NSString *)message  confirmHandler:(void(^)(UIAlertAction *))confirmActionHandle viewController:(UIViewController *)vc;

//没有取消按钮(确认后有跳转)
+(UIAlertController *)alertTitle:(NSString *)title mesasge:(NSString *)message preferredStyle:(UIAlertControllerStyle *)preferredStyle  confirmHandler:(void(^)(UIAlertAction *))confirmActionHandler viewController:(UIViewController *)vc;

//有取消按钮的
+(UIAlertController *)alertTitle:(NSString *)title mesasge:(NSString *)message preferredStyle:(UIAlertControllerStyle *)preferredStyle  confirmHandler:(void(^)(UIAlertAction *))confirmHandler cancleHandler:(void(^)(UIAlertAction *))cancleHandler viewController:(UIViewController *)vc;

@end

方法的实现

//没有取消按钮的
+(UIAlertController *)alertMesasge:(NSString *)message  confirmHandler:(void(^)(UIAlertAction *))confirmActionHandle viewController:(UIViewController *)vc
{

     UIAlertController *alertController=[UIAlertController alertControllerWithTitle:@"温馨提示" message:message preferredStyle:UIAlertControllerStyleAlert];
    
    UIAlertAction *confirmAction=[UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:confirmActionHandle];
    
    [alertController addAction:confirmAction];
    
    [vc presentViewController:alertController animated:YES completion:nil];
    
    return alertController;
    
}

//没有取消按钮(确认后有跳转)
+(UIAlertController *)alertTitle:(NSString *)title mesasge:(NSString *)message preferredStyle:(UIAlertControllerStyle *)preferredStyle  confirmHandler:(void(^)(UIAlertAction *))confirmActionHandler viewController:(UIViewController *)vc
{

    UIAlertController *alertController=[UIAlertController alertControllerWithTitle:title message:message preferredStyle:*preferredStyle];
    
    UIAlertAction *confirmAction=[UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:confirmActionHandler];
    
    [alertController addAction:confirmAction];
    
    [vc presentViewController:alertController animated:YES completion:nil];
    
    return alertController;

}


//有取消按钮的
+(UIAlertController *)alertTitle:(NSString *)title mesasge:(NSString *)message preferredStyle:(UIAlertControllerStyle *)preferredStyle  confirmHandler:(void(^)(UIAlertAction *))confirmHandler cancleHandler:(void(^)(UIAlertAction *))cancleHandler viewController:(UIViewController *)vc
{

    UIAlertController *alertController=[UIAlertController alertControllerWithTitle:title message:message preferredStyle:*preferredStyle];
     
    UIAlertAction *confirmAction=[UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:confirmHandler];
    
    UIAlertAction *cancleAction = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:cancleHandler];
    
    [alertController addAction:confirmAction];
    [alertController addAction:cancleAction];
    
    [vc presentViewController:alertController animated:YES completion:nil];
    
    return alertController;

}

工具的使用

[AlertControllerTool alertMesasge:@"密码不一致，请重新输入" confirmHandler:nil viewController:self];
