IOS 学习笔记 Button引发不同UIAlertView 事件

创建一个ViewController, 添加配套nibs文件。

拖拽Button 在storyboard 上创建按键，关联到头文件中。

ViewController.h 头文件中事件关联的方法声明

#import 

@interface ViewController : UIViewController

-(IBAction)showMessage;

- (IBAction)showMTwo;

- (IBAction)showMThree;

- (IBAction)showMFour;

- (IBAction)showMFive;

@end

在ViewController.m 中定义方法

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {

    [super viewDidLoad];

    // Do any additional setup after loading the view, typically from a nib.

}

- (void)didReceiveMemoryWarning {

    [super didReceiveMemoryWarning];

    // Dispose of any resources that can be recreated.

}

- (IBAction)showMessage

{

    UIAlertView *helloButtonAlert = [[UIAlertView alloc]initWithTitle:@"Default Alert View" message:@"Default" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK",@"ThirdButton",@"Fourth Button",@"Too more Button", nil];

    [helloButtonAlert show];

}

- (IBAction)showMTwo

{

        UIAlertView *helloButtonAlert1 = [[UIAlertView alloc]initWithTitle:@"This is Button two" message:@"This is true" delegate:nil cancelButtonTitle:@"That is NO.1 button!!" otherButtonTitles:nil];

    

        [helloButtonAlert1 show];

}

- (IBAction)showMThree

{

    UIAlertView *helloButtonAlert = [[UIAlertView alloc]initWithTitle:@"ButtonThree" message:@"This part is message" delegate:@"This part is delegate" cancelButtonTitle:@"cancel Button" otherButtonTitles:nil];

        [helloButtonAlert show];    

}

- (IBAction)showMFour

{

    UIAlertView *helloButtonAlert = [[UIAlertView alloc]initWithTitle:@"ButtonFour" message:@"Default" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK",nil];

        [helloButtonAlert show];

}

- (IBAction)showMFive

{

    UIAlertView *helloButtonAlert = [[UIAlertView alloc]initWithTitle:@"BUttonFive" message:@"Default" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK",@"ThirdButton", nil];

    [helloButtonAlert show];

}

@end

运行时查看不同方法给予的AlertView 并不相同：

      

  

UIAlertView 中没有添加点击事件。

GoodLuck!
