iOS Email App Message?

[iLoveDeveloping]

Hey,

Im sending a message in my app by email, but i cant get the spacing to work in the code!

I have :

NSString *emailBody = @"Your Message In Here!";

But if i write the message like this:

NSString *emailBody = @"Your Message In Here!

Signed Blah Blah";

It doesn't work and i get a whole load of errors! How do i format my email text in the code, so i can make it look like a real formatted email?

Just use escape chars. \n is the char for new line break. use two of those so your string would look like.

NSString *emailBody = @"Your Message In Here!\n\nSigned Blah Blah"

Just wondering here. Wouldn't it be better practice to enclose it on parentheses?

NSString *emailBody = @("Your Message In Here!\n\nSigned Blah Blah")

Just wondering out loud here.

No, not really. In fact, that will give you a compile error. Don't do it.

I'm curious why you would think that better though. Care to elaborate?

Just cause when ever I was messing around with anything that displays text (NSLog) I wrote it as this:

NSLog(@"text here");

Just wondering if it carried over yet. Guess not, thanks for the clarification

The difference is that with NSLog you're putting the string @"..." inside the parentheses.

NSLog(@"text");

The way you had it, the parentheses were inside the @, which the compiler will choke on. And the reason for the parentheses with NSLog is that NSLog is a C-style method call and not an Objective-C method call.

Oh duh, excuse me, I'm a learning programmer here (I dont have my training wheels yet, just learning to walk so to speak). So would it still give a complier error if I had typed it right? Or is that specific to NSLog?

I don't see why surrounding an NSString with parenthesis wouldn't work, its just kind of pointless. Think about it like a math problem. 1+1 is no different than (1+1). Its very different from the quotes in NSLog() because NSLog() is a method. Its good that you're curious and asking questions though. So if you're trying to do something like this:

(@"%i",integer);

It won't work because its different from NSLog().

Ah see that clears it up for me, I didnt know NSLog was actually NSLog().
