Question

我仍然无法使用之前的回答拨打电话。我正在解析xml文件以获取电话号码值（aMarker.phone =电话号码）。其中marker是我在解析器控制器中获取的xml文件中的属性。我可以在按钮标题上设置此电话号码字符串。但是通过点击按钮，我无法拨打该号码。看我的代码

 - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath  *)indexPath {
 if(BGView.hidden == YES)
{
BGView.hidden = NO;

NSIndexPath *selectedIndexPath = [self.tableView indexPathForSelectedRow];
  marker *aMarker = (marker *)[appDelegate.markers objectAtIndex:selectedIndexPath.row];
for (int selectedIndexPath = 0; selectedIndexPath < [appDelegate.markers count];    selectedIndexPath++)
{       [p_Bcard setTitle:[NSString stringWithFormat:@"%@",aMarker.phone]forState:UIControlStateNormal];
 //getting correct number on p_Bcard button title.
}
}}

按钮操作代码：

 -(IBAction)phonecallUpadated
  {
NSIndexPath *selectedIndexPath = [self.tableView indexPathForSelectedRow];

marker *aMarker = (marker *)[appDelegate.markers  objectAtIndex:selectedIndexPath.row];
for (int selectedIndexPath = 0; selectedIndexPath < [appDelegate.markers count];  selectedIndexPath++)
{
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@",aMarker.phone]]];

 //not able to call pressing p_Bcard button using above action. method get call by setting breakpoint.

我该怎么做才能传递正确的字符串号码来拨打电话。 }

Answer 1

要拨打电话，您需要在tel:附加电话号码。它应该如下：

NSString *phone_number = @"18005551212"; // get dynamically from your code
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:[NSString stringWithFormat:@"tel:%@", phone_number]]];

Answer 2

首先将您的电话号码转换为UTF8编码字符串然后再制作NSURL。两个单词之间的另一个明智的设置％20（两个电话号码之间）。

如何通过xml解析器值从iphone应用程序调用？
