[iOS] UIAlertView

我是UIAlertView,我負責通知使用者一些訊息

 





第1步:建立一個名為"UIAlertView"的"Single View Application"專案
 

第2步:加入一個UIButton,並加入"buttonTouch:"方法以連結使用者按下按鈕後的"Touch Up Inside"事件。


第3步:於"buttonTouch:"方法中加入建立與顯示UIAlertView的程式。透過"initWithTitle:message:delegate:cancelButtonTitle:otherButtonTitles:"完成UIAlertView的初始化動作,最後呼叫"show"顯示UIAlertView。

- (IBAction)buttonTouch:(id)sender { UIAlertView *view =
    //initWithTitle <= 視窗的標題文字
    //message <= 顯示給使用者的訊息    //delegate <= alertView按鈕操作的委派,若無則設定為nil 
    //cancelButtonTitle <= 關閉視窗的主按鈕標題文字 
    //otherButtonTitles <= 其他按鈕,若無則設定為nil
    [[UIAlertView alloc] initWithTitle:@"通知標題" 
                               message:@"早安"
                              delegate:nil 
                     cancelButtonTitle:@"關閉" 
                     otherButtonTitles:nil, nil];

    //show方法,顯示UIAlterView
    [view show]; 


第6步:執行程式,按下Button按鈕,UIAlertView即會顯示出來跟您說:早安


 




想要讓UIAlertView擁有多個按鈕,讓使用者有不同的選擇,比如說"同意"與"取消"?!

敬請期待...
