[dictionary setobject:[[self imagenametextfield]text]                     forkey:@"identity"];  //i tried  //identity=[identity stringbyappendingformat:@"txt" didn't work        nsstring *audiostring = [dictionary objectforkey:@"pictureaudiokey"];      audiostring = [audiostring stringbyappendingformat:@".caf"];      [dictionary setobject:[[self imagenametextfield]text]                     forkey:@"pictureaudiokey"];  

does have suggestions?

 

you post isn't making sense me.

first sentence wrong "nsmutablearray".

mention 3 objects, looks creating 1 input field, kind of question need that.

mention want append dictionary, in fact overriding values 3 keys pictureaudiokey, photoimagekey, , identity. if code looks this, don't bother adding values begin with, or actual append using different key names.

set initial value photoimagekey .jpg extension later mention not using extension file load .png. make mind using.

unless user typed in extension, code suggests shouldn't, should appending .caf , .txt input result before appending or altering dictionary.

in last few lines of code, extracting value of pictureaudiokey, "main.caf", altering adding .caf, , doing nothing result. expect result of alteration "main.caf.caf".

think might want lines this;

code:

  [dictionary setobject:[[[self imagenametextfield] text] stringbyappendingformat:@".txt"] forkey:@"identity"];  [dictionary setobject:[[[self imagenametextfield] text] stringbyappendingformat:@".caf"] forkey:@"pictureaudiokey"];  [dictionary setobject:[[[self imagenametextfield] text] stringbyappendingformat:@".jpg"] forkey:@"photoimagekey"];  

i'll again, if want append values, need new key names because these overwrite values initialized keys.

since see no retains or releases assuming using arc. biggest hint use of class method dictionarywithobjectsandkeys: returns non-retained object. believe arc retain you.

oh, have declared dictionary local variable, how getting next view controller or otherwise saving it?

code incomplete , makes difficult others you.
