I would like to do the following
[controller setMessageBody:[NSString stringWithFormat:@\"%@ %@ <
Just use
@"....<a href=\"%%@\">Hello</a>..."

@"<a href=\"%@\">Hello</a>"
if you include it using %@ in the format string. The %@ is only interpreted in the first argument of the stringWithFormat: method here.
%@
stringWithFormat:
