UIAlertView IndexButton

Question

我的地图上有注释的代码.

//alert view

if ([ann.title isEqual: @"Al-saidiya"]) {

    NSString *msg=@"Phone No : 079011111";
    UIAlertView *alert1 = [[UIAlertView alloc]initWithTitle:@"Contact" message:msg delegate:self cancelButtonTitle:@"cancel" otherButtonTitles:@"Call Us", nil];



    [alert1 show];
}
else if ([ann.title isEqual: @"Al-Kadmiya"]) {


    NSString *msg=@"Phone No : 07902222222";
    UIAlertView *alert2 = [[UIAlertView alloc]initWithTitle:@"Contact" message:msg delegate:self cancelButtonTitle:@"ok" otherButtonTitles:@"Call Us", nil];
    [alert2 show];
}

else if ([ann.title isEqual: @"Palestine St"]) {

    NSString *msg=@"Phone No : 0790333333";
    UIAlertView *alert3 = [[UIAlertView alloc]initWithTitle:@"Contact" message:msg delegate:self cancelButtonTitle:@"ok" otherButtonTitles: @"Call Us",nil];
    [alert3 show];
}

else if ([ann.title isEqual: @"Karada Maryam"]){

    NSString *msg=@"Phone No : 07905867";
    UIAlertView *alert4 = [[UIAlertView alloc]initWithTitle:@"Contact" message:msg delegate:self cancelButtonTitle:@"ok" otherButtonTitles:@"Call Us", nil];
    [alert4 show];
}

else if ([ann.title isEqual: @"Mansour Office"])  {

   NSString *msg=@"Phone No : 07954212";
    UIAlertView *alert5 = [[UIAlertView alloc]initWithTitle:@"Contact" message:msg delegate:self cancelButtonTitle:@"ok" otherButtonTitles: @"Call Us",nil];
    [alert5 show];
}

else if ([ann.title isEqual: @"Hunting Club"]) {


    NSString *msg=@"Phone No : 079337745";
    UIAlertView *alert6 = [[UIAlertView alloc]initWithTitle:@"Contact" message:msg delegate:self cancelButtonTitle:@"ok" otherButtonTitles: @"Call Us",nil];
    [alert6 show];
}
else if ([ann.title isEqual: @"Al-jadriya"])  {

    NSString *msg=@"Phone No : 07976231";
    UIAlertView *alert7 = [[UIAlertView alloc]initWithTitle:@"Contact" message:msg delegate:self cancelButtonTitle:@"ok" otherButtonTitles: @"Call Us",nil];
    [alert7 show];
}

else if ([ann.title isEqual: @"Al-jamea'a"]) {

    NSString *msg=@"Phone No : 07865323";
    UIAlertView *alert8 = [[UIAlertView alloc]initWithTitle:@"Contact" message:msg delegate:self cancelButtonTitle:@"ok" otherButtonTitles: @"Call Us",nil];
    [alert8 show];
}

}

当我应用这个方法时：

-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {

    if (buttonIndex==1){
        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:[NSString stringWithFormat:@"telprompt://576576576"]]];
        NSLog(@"It works!");
    }
}

它已经应用于上面的每一个警报对象，并以相同的号码。我希望每个警报对象都有自己的电话号码，当我想打电话时。

首先在上面的代码中设置警告视图中的标记，然后在下面的方法中设置标记。就像这样：-

     -(void)alertView:(UIAlertView *)alertView    
   clickedButtonAtIndex:(NSInteger)buttonIndex 
 {

    int indexValue=alertView.tag;

   switch (indexValue)
  {
  case 0:
    NSLog (@"zero");
   //your code
    break;
  case 1:
    NSLog (@"one");
  //your code
    break;
  case 2:
    NSLog (@"two");
  //your code
    break;
  case 3:
    NSLog (@"three");
  // your code
    break;
  case 4:
    NSLog (@"four");
  //your code
    break;
  case 5:
    NSLog (@"five");
  // your code
    break;
...... Up to

   case 8:
  // your code
   break;
  default:
    NSLog (@"done");
    break;
   }

只需在警告视图中添加一个标记即可。

if ([ann.title isEqual: @"Al-saidiya"]) {

    NSString *msg=@"Phone No : 079011111";
    UIAlertView *alert1 = [[UIAlertView alloc]initWithTitle:@"Contact" message:msg delegate:self cancelButtonTitle:@"cancel" otherButtonTitles:@"Call Us", nil];

    alert1.tag = 0; // <--

    [alert1 show];
}

并检查alertView:clickedButtonAtIndex:中的标记

if (alertView.tag == 0) {
  // call Al-saidiya
}
...

好吧，即使tilo提出的解决方案有效，当您有多个对象实例(如UIAlertview )时，我认为这并不是正确的方法。

我建议你用积木代替。这些类别 (项目对UIActionSheet使用相同的模式)允许您将操作块绑定到alertView中的特定按钮。

使用这种方法，您可以使用委托模式消除所有if/switch语句。
