ViewController.h中的代码如下：
#import @interface ViewController : UIViewController @end
ViewController.m中的详细代码：
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib
//初始化AlertView
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"AlertViewTest"
message:@"message"
delegate:self
cancelButtonTitle:@"Cancel"
otherButtonTitles:@"OtherBtn",nil];
//设置标题与信息，通常在使用frame初始化AlertView时使用
alert.title = @"AlertViewTitle";
alert.message = @"AlertViewMessage";
//这个属性继承自UIView，当一个视图中有多个AlertView时，可以用这个属性来区分
alert.tag = 0;
//只读属性，看AlertView是否可见
NSLog(@"%d",alert.visible);
//通过给定标题添加按钮
[alert addButtonWithTitle:@"addButton"];
//按钮总数
NSLog(@"number Of Buttons :%d",alert.numberOfButtons);
//获取指定索引的按钮标题
NSLog(@"buttonTitleAtIndex1:%@",[alert buttonTitleAtIndex:1]);
NSLog(@"buttonTitleAtIndex2:%@",[alert buttonTitleAtIndex:2]);
//获取取消按钮的索引
NSLog(@"cancelButtonIndex:%d",alert.cancelButtonIndex);
//获取第一个其他按钮的索引
NS [alert show];
[alert release];
}
#pragma marks -- UIAlertViewDelegate --
//根据被点击按钮的索引处理点击事件
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
NSLog(@"clickButtonAtIndex:%d",buttonIndex);
}
//AlertView已经消失时执行的事件
-(void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex
{
NSLog(@"didDismissWithButtonIndex");
}
//ALertView即将消失时的事件
-(void)alertView:(UIAlertView *)alertView willDismissWithButtonIndex:(NSInteger)buttonIndex
{
NSLog(@"willDismissWithButtonIndex");
}
//AlertView的取消按钮的事件
-(void)alertViewCancel:(UIAlertView *)alertView
{
NSLog(@"alertViewCancel");
}
//AlertView已经显示时的事件
-(void)didPresentAlertView:(UIAlertView *)alertView
{
NSLog(@"didPresentAlertView");
}
//AlertView即将显示时
-(void)willPresentAlertView:(UIAlertView *)alertView
{
NSLog(@"willPresentAlertView");
}
- (void)viewDidUnload
{
[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
