UIAlertView *alert=[[UIAlertView alloc] initWithTitle:@"Alert!" message:@"Here is an alert message!" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil] ;
[alert show];
[alert release];
要加入多個按鈕則使用"otherButtonTitles達成"
UIAlertView *alert = [[[UIAlertView alloc] initWithTitle:@"alert" message:@"Here is an alert message!" delegate:self cancelButtonTitle:@"1" otherButtonTitles:@" 2", @" 3",nil ]autorelease];
[alert show];
執行如下
按下確定後的處理函式 可以透過delegate指派來達成 多個按鍵 會回傳buttonIndex 從0開始 然後再m檔裡實作
- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex {
if (buttonIndex == 0) { // and they clicked 1.
NSLog(@"1 clicked");
}else if(buttonIndex==1){
NSLog(@"2 clicked");
}else if(buttonIndex==2){
NSLog(@"3 clicked");
}
}
