這次做一個(gè)點(diǎn)擊撥打按鈕，跳出提示框來(lái)，點(diǎn)確定，直接打出電話。當(dāng)然，模擬器不行的。

-(void)xxxxx{
//在線客服
            UIAlertView * alertView = [[UIAlertView alloc] initWithTitle:TELEPHONE_NUM message:@"是否撥打客服電話" delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"確定", nil];
            alertView.delegate = self;
            [alertView show];
};

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
    NSLog(@"+++++++++++++%ld",(long)buttonIndex);
    if (buttonIndex==1) {
        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:[NSString stringWithFormat:@"tel://%@", TELEPHONE_NUM]]];
    }
}

這樣就行了。
