IOS提示控件UIActionSheet,UIAlertView

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];

}
