class - LaTeX: \newenvironment with only one optional arg (and no mandatory) -

-


try set new environment within class take optional argument, or none.

this used : 

\begin{myenv}          -->  "label:"

or 

\begin{myenv}[mylabel] -->  "label: mylabel"

i try define environment basic macros. rather not use xparse package.

i have found several examples of \newenvironment optional argument mandatory one. not need mandatory argument!

is there way \newenvironment or \def macros ?

no problem, declare environment 1 argument, , make optional:

\documentclass{minimal} \newenvironment*{myenv}[1][]{%   label: #1%   \par   \ignorespaces }{%   \par   end%   \par   \ignorespacesafterend } \begin{document} \begin{myenv}   abc \end{myenv} \begin{myenv}[mylabel]   abc \end{myenv} \end{document}

i define tasks using nsdictionary, i'd save in plist file (i didn't have luck core data far), got stuck @ 2 points: -- when using initwithobjectsandkeys: can change data type number or boolean, using nsdate's numberwithint: , numberwithbool: methods, respectively. can't seem find method change type date though. couldn't find in documentation. -- second problem ran nested arrays. how can add them dictionary? i have uploaded picture here of trying achieve. thank in advance! do mean nsnumber 's +numberwithint: , +numberwithbool: methods, not nsdate ? it's nsnumber defines methods. to convert number date, depends on number is. if it's unix timestamp, [nsdate datewithtimeintervalsince1970:thetimestampinseconds] . as adding nsarray objects dictionary: [yourdictionary setobject:yourarray forkey:@"somekey"]; you'll have post code if need more question isn't clear.
