Convert NSDictionary array values into NSString format for MFMailComposeViewController - xcode

Question

I have a UIPickerViewDelegate that allows the user to select a term from the picker and see the term's definition by using NSDictionary to access data stored in a plist file. I also have a MFMailComposeViewController to allow the user to email the term and it's definition elsewhere.
But I can't seem to get the term and definition formatted properly for entry into the email. I looked at various "convert NSDictionary to NSString" solutions, but none seem to offer what I need, including variations of Term = [dict objectForKey:#"Term"].
Under viewDidLoad, I have the following:
NSString *path = [[NSBundle mainBundle] pathForResource:#"Glossary" ofType:#"plist"];
NSDictionary *dict = [[NSDictionary alloc] initWithContentsOfFile:path];
self.termArray = [dict objectForKey:#"Term"];
self.definitionArray = [dict objectForKey:#"Definition"];
My pickerView code includes this:
NSString *resultString = [[NSString alloc] initWithFormat:
#"%#",
[definitionArray objectAtIndex:row]];
definitionLabel.text = resultString;
NSString *termString = [[NSString alloc] initWithFormat:
#"%#",
[termArray objectAtIndex:row]];
The code for showEmail contains:
int definitionIndex = [self.termPicker selectedRowInComponent:0];
NSString *emailTitle = [NSString stringWithFormat:#"Definition of %#", termLabel];
NSString *emailDefinition = [definitionArray objectAtIndex:definitionIndex];
NSString *messageBody = [NSString stringWithFormat:#"The definition of <B>%#</B> is:<P> <B>%#</B>", termLabel, emailDefinition];
MFMailComposeViewController *mc = [[MFMailComposeViewController alloc] init];
mc.mailComposeDelegate = self;
[mc setSubject:emailTitle];
[mc setMessageBody:messageBody isHTML:YES];
I would like the email title and message body to pull from the Term selected in the picker and the Definition associated with it. I'm sure it must be a simple formatting issue, but I can't figure it out.
