打开phone.app之前显示UIAlertView [英] Display UIAlertView before opening phone.app

问题描述

我在地图上有一个按钮，按钮上有一个标签. 在标签上，我有一个来自plist的电话号码. plist中电话号码的变量称为"storePhone"，我是通过以下方式实现的:

I have a view on map with a button and a label on the button. On the label i have phone number that comes from a plist. The variable of the phone number in the plist called "storePhone" and i implemented it in this way:

text4.text = myAnn.storePhone;

我采用了这种方法来按下按钮并打开phone.app来拨打号码. 一切正常，但我希望UIViewAlert对用户说:您要拨打该号码，确定吗?"在phone.app打开之前.

I made this method for pressing the button and opening the phone.app for dialing the number. Everything works great but i want a UIViewAlert to say to the user something like:"your going to dial this number, are you sure?" before the phone.app is open.

我该怎么做?

这是我的按钮方法:

-(IBAction)callToStore
{
    NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"tel:%@", text4.text]];
    [[UIApplication sharedApplication] openURL:url];
}

谢谢.

推荐答案

我做到了.
这是您的操作方式:

I did it.
This is how you do it:

- (IBAction)moreInfoViewAlert:(id)sender
{
    UIAlertView *message = [[UIAlertView alloc] initWithTitle:@"חיוג לסניף"
                                                  message:@"הנך עומד/ת לבצע חיוג, האם את/ה בטוח?"
                                                 delegate:self
                                        cancelButtonTitle:@"ביטול"
                                        otherButtonTitles:@"חיוג", nil];
    [message show];
}

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
    NSString *title = [alertView buttonTitleAtIndex:buttonIndex];

    if([title isEqualToString:@"חיוג"])
    {
        NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"tel:%@", text4.text]];
        [[UIApplication sharedApplication] openURL:url];
    }
}

将IBAction方法附加到您的按钮上，一切就很好了.

Attach the IBAction method to your button and you're good to go.
