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];
