iOS开发学习之#提醒处理#（1）响应提醒视图

来源：互联网发布：尤克里里推荐知乎编辑：程序博客网时间：2024/06/03 19:11

在这里我用到了视图库里的Navigation Controller导航控制器。

提醒操作主要用到了UIAlertviewDelegate协议中的alertView:clickButtonAtIndex:方法实现，其语法形式如下：

- (void) alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex；

(UIAlertView *)alertView用来指定警告视图中包含的按钮，(NSInteger)buttonIndex用来指定点击的按钮的索引

核心代码如下：

TableViewController.h

#import <UIKit/UIKit.h>@interface TableViewController : UITableViewController<UITableViewDataSource,UITabBarDelegate,UIAlertViewDelegate>{    NSMutableArray *a;}- (IBAction)aa:(id)sender;- (IBAction)bb:(id)sender;@end

TableViewController.m部分代码片段

- (IBAction)aa:(id)sender {    UIAlertView *a = [[UIAlertView alloc]initWithTitle:@"编辑" message:@"请选择项目" delegate:self cancelButtonTitle:@"Canel" otherButtonTitles:@"Add",@"Delete", nil];    [a show];}- (void) alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{    NSString *b = [alertView buttonTitleAtIndex:buttonIndex];    if ([b isEqualToString:@"Delete"]) {        [self setEditing:YES];    }    if ([b isEqualToString:@"Add"]) {       UIAlertView *a1 = [[UIAlertView alloc]initWithTitle:@"添加" message:@"确定要添加联系人吗" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles: nil];        [a1 show];    }}- (IBAction)bb:(id)sender {    [self setEditing:NO];}- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath{    if (editingStyle == UITableViewCellEditingStyleDelete) {        [a removeObjectAtIndex:indexPath.row];        [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];    }}
