iphone中常用的消息提示控件,就是UIActionSheet和UIAlertView了,在Web开发中,UIActionSheet就像是confirm(),而UIAlertView就像是alert()一样
UIActionSheet
UIAlertView
但在iphone中,这两个控件的功能可以自定义
定义两个控件事件方法
- #import <UIKit/UIKit.h>
- @interface ViewController : UIViewController
- - (IBAction)showActionSheet:(id)sender;
- - (IBAction)showAlertView:(id)sender;
- @end
实现事件
- - (IBAction)showActionSheet:(id)sender
- {
- UIActionSheet *showSheet = [[UIActionSheet alloc] initWithTitle:@"提示信息" delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:@"确认" otherButtonTitles:nil];
- [showSheet showInView:self.view];
- [showSheet release];
- }
- - (IBAction)showAlertView:(id)sender
- {
- UIAlertView *alterView = [[UIAlertView alloc] initWithTitle:@"提示信息" message:@"啊啊" delegate:self cancelButtonTitle:@"取消" otherButtonTitles: nil];
- [alterView show];
- [alterView release];
- }
UIActionSheet委托代码 ,当点击确认后,弹出UIAlertView窗口提示信息
- - (void) actionSheet: (UIActionSheet *) actionSheet
- didDismissWithButtonIndex:(NSInteger)buttonIndex
- {
- NSString *msg = nil;
- if (buttonIndex != [actionSheet cancelButtonIndex]) {
- msg = [NSString stringWithString:@"你选择了确认"];
- }else {
- msg = [NSString stringWithString:@"你选择了取消"];
- }
- UIAlertView *alter = [[UIAlertView alloc] initWithTitle:@"提示信息" message:msg delegate:self cancelButtonTitle:@"取消" otherButtonTitles: nil];
- [alter show];
- [alter release];
- [msg release];
- }
