苹果手机出现object object_objectc

ios object-c 弹框功能

1、BaseViewController中

 BaseViewController.h

@interface BaseViewController : UIViewController @end @interface BaseViewController (Alert) / 系统弹窗双选项 @param title 标题 @param message 文本内容 @param ok 确定 @param cancle 取消 @param OK 确定按钮回调 */ - (void)alertTitle:(NSString *)title andMessage:(NSString *)message andOK:(NSString*)ok andCancle:(NSString*)cancle andBlock:(void (^)(UIAlertAction *action))OK; / 系统弹窗单选项 @param title 标题 @param message 具体信息 @param handler 回调 */ - (void)alertTitle:(NSString*)title andMessage:(NSString*)message andCancleBlock:(void (^ __nullable)(UIAlertAction *action))handler; / 系统弹窗双选回调 @param title 标题 @param message 内容 @param ok ok @param cancle cancle @param OK ok回调 @param cancleBlock 取消回调 */ - (void)alertTitle:(NSString *)title andMessage:(NSString *)message andOK:(NSString*)ok andCancle:(NSString*)cancle andBlock:(void (^)(UIAlertAction *action))OK andCancleBlock:(void (^)(UIAlertAction *action))cancleBlock; @end

BaseViewController.m

@interface BaseViewController () @end @implementation BaseViewController @end @implementation BaseViewController (Alert) - (void)alertTitle:(NSString *)title andMessage:(NSString *)message andCancleBlock:(void (^ __nullable)(UIAlertAction *action))handler { 
    UIAlertController *alertController = [UIAlertController alertControllerWithTitle:title message:message preferredStyle:UIAlertControllerStyleAlert]; UIAlertAction *okAction = [UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:handler]; [alertController addAction:okAction]; [self presentViewController:alertController animated:YES completion:nil]; } - (void)alertTitle:(NSString *)title andMessage:(NSString *)message andOK:(NSString*)ok andCancle:(NSString*)cancle andBlock:(void (^)(UIAlertAction *action))OK { 
    UIAlertController *alertController = [UIAlertController alertControllerWithTitle:title message:message preferredStyle:UIAlertControllerStyleAlert]; UIAlertAction *okAction = [UIAlertAction actionWithTitle:ok style:UIAlertActionStyleDestructive handler:OK]; [alertController addAction:okAction]; UIAlertAction *cancleAction = [UIAlertAction actionWithTitle:cancle style:UIAlertActionStyleDefault handler:nil]; [alertController addAction:cancleAction]; [self presentViewController:alertController animated:YES completion:nil]; } - (void)alertTitle:(NSString *)title andMessage:(NSString *)message andOK:(NSString*)ok andCancle:(NSString*)cancle andBlock:(void (^)(UIAlertAction *action))OK andCancleBlock:(void (^)(UIAlertAction *action))cancleBlock { 
    UIAlertController *alertController = [UIAlertController alertControllerWithTitle:title message:message preferredStyle:UIAlertControllerStyleAlert]; UIAlertAction *okAction = [UIAlertAction actionWithTitle:ok style:UIAlertActionStyleDestructive handler:OK]; [alertController addAction:okAction]; UIAlertAction *cancleAction = [UIAlertAction actionWithTitle:cancle style:UIAlertActionStyleDefault handler:cancleBlock]; [alertController addAction:cancleAction]; [self presentViewController:alertController animated:YES completion:nil]; } @end

2、使用弹框

#import "BaseViewController.h" @interface MineController : BaseViewController @end

#import "MineController.h" @interface MineController () @end @implementation MineController - (IBAction)deleteButton:(id)sender { 
    @weakify(self); [self alertTitle:@"确定删除" andMessage:@"" andOK:@"确定" andCancle:@"取消" andBlock:^(UIAlertAction * _Nonnull action) { 
    @strongify(self); }]; } @end
