iOS stringWithFormat

[beesbane]

What is wrong with this?

PhoneNum.text = [[NSString alloc] initWithFormat:@"Phone:",[PhoneData valueForKey:@"number"]];

I can't figure how to write it right.

There are no formatting placeholders in the string?

Like for example...?

Is there a better or simpler way for me to do this?

Open the NSString documentation, go to initWithFormat: section. Read what it says. Follow the Formatting String Objects link for examples and the String Format Specifiers for a list of all the accepted format placeholders.

If you still need examples I suggest Google will provide thousands.

Alright, I've gotten it to work now. As long as it is set up in viewDidLoad and on a label, it works.

How can I set it up in an IBAction?

-(IBAction) phoneBtn{
	
	NSString *phoneString = [NSString localizedStringWithFormat:@"%@  %@\n", @"tel://", [MasterData valueForKey:@"Phone"]];
	
	[[UIApplication sharedApplication] openURL:[NSURL URLWithString:phoneString]];
	
}

Oops... I feel a bit silly. I had a double space in the URL. Of course it wouldn't work.

Writing it like this worked:

NSString *phoneString = [NSString localizedStringWithFormat:@"%@%@\n", @"tel://", [dvdData valueForKey:@"Phone"]];
	[[UIApplication sharedApplication] openURL:[NSURL URLWithString:phoneString]];

No worries, good to hear you've got it working. I've asked the moderators to move this to iPhone Programming. I'd suggest you might want to post future threads of a similar nature in there.
