enter code here-(IBAction)Call:(id)sender{
//[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://18005551234"]];
/*NSString *phoneStr = [[NSString alloc] initWithFormat:@"tel:%@",phoneNumber.text];
NSURL *phoneURL = [[NSURL alloc] initWithString:phoneStr];
[[UIApplication sharedApplication] openURL:phoneURL];
[phoneURL release];
[phoneStr release];*/
NSURL *url = [ [ NSURL alloc ] initWithString: @"tel:212-555-1234" ];
[[UIApplication sharedApplication] openURL:url];

} 在上面的代码中，我使用了多种方法，但没有人工作。当我在函数上实现断点时，它说这超出了范围。这有什么问题吗？

NSURL *url = [ [ NSURL alloc ] initWithString: @"tel:212-555-1234" ];
[[UIApplication sharedApplication] openURL:url];

您应该删除电话号码中的连字符“-”以及方括号“(”、“)”。除数字外不应有特殊字符。

NSCharacterSet *specialCharSet = [NSCharacterSet characterSetWithCharactersInString:@" )(-,"];
NSArray *components = [phoneNumber.text componentsSeparatedByCharactersInSet:specialCharSet];
NSString *phoneStr = [components componentsJoinedByString:@""];
phoneStr = [NSString stringWithFormat:@"tel:%@", phoneStr];
NSURL *url = [[NSURL alloc] initWithString:phoneStr];
[[UIApplication sharedApplication] openURL:url];

You should remove the hypens "-", and also the brackets "(", ")" from the phone number. No special characters should be there except numbers.

NSCharacterSet *specialCharSet = [NSCharacterSet characterSetWithCharactersInString:@" )(-,"];
NSArray *components = [phoneNumber.text componentsSeparatedByCharactersInSet:specialCharSet];
NSString *phoneStr = [components componentsJoinedByString:@""];
phoneStr = [NSString stringWithFormat:@"tel:%@", phoneStr];
NSURL *url = [[NSURL alloc] initWithString:phoneStr];
[[UIApplication sharedApplication] openURL:url];
