ios - Parse 122 error upload -

if save text without having text in field error message in parse.com: update failure - operation couldn't completed(parse error 122.) if press ok , try dismiss view cancel(a button item) app crashes. think valid file name @ parse.com has contain @ least 1 character. maybe can do stop user saving when not enter text? ideas?

this code:

- (ibaction)save:(id)sender {     // create pfobject profile information     pfuser *profile = [pfuser currentuser];     [profile setobject:nametextfield.text forkey:@"name"];     [profile setobject:titletextfield.text forkey:@"title"];     [profile setobject:locationtextfield.text forkey:@"location"];      // profile image     nsdata *imagedata = uiimagejpegrepresentation(profileimageview.image, 0.8);      nsstring *filename = [nsstring stringwithformat:@"%@", nametextfield.text];      pffile *imagefile = [pffile filewithname:filename data:imagedata];     [profile setobject:imagefile forkey:@"profileimagefile"];      // show progress     mbprogresshud *hud = [mbprogresshud showhudaddedto:self.view animated:yes];     hud.mode = mbprogresshudmodeindeterminate;     hud.labeltext = @"updating";     [hud show:yes];      // upload profile parse      if(nametextfield.text.length==0 && titletextfield.text.length==0 && locationtextfield.text.length==0)      [hud hide:yes];      [profile saveinbackgroundwithblock:^(bool succeeded, nserror *error) {              if (error) {                 [[[uialertview alloc] initwithtitle:@"profile information" message:@"fill in atleast 1 field" delegate:nil cancelbuttontitle:@"ok" otherbuttontitles:nil]show];                  [hud hide:yes];             }             else {             // show success message             uialertview *alert = [[uialertview alloc] initwithtitle:@"" message:@"successfully updated profile" delegate:self cancelbuttontitle:@"ok" otherbuttontitles:nil, nil];             [alert show];              [hud hide:yes];              [self dismissviewcontrolleranimated:yes completion:nil];              [self performseguewithidentifier:@"profile" sender:self];         }     }]; }   - (ibaction)cancel:(id)sender {      [self dismissviewcontrolleranimated:yes completion:nil];     [self performseguewithidentifier:@"profile" sender:self]; }

test if 1 letter theory true. change:

nsstring *filename = [nsstring stringwithformat:@"%@", nametextfield.text]; 

to:

nsstring *filename = [nsstring stringwithformat:@"file%@", nametextfield.text]; 

2

or avoid if it's blank. this:

nsstring *filename = [nsstring stringwithformat:@"%@", nametextfield.text];  pffile *imagefile = [pffile filewithname:filename data:imagedata]; [profile setobject:imagefile forkey:@"profileimagefile"]; 

becomes:

if (nametextfield.text) {     nsstring *filename = [nsstring stringwithformat:@"%@", nametextfield.text];      pffile *imagefile = [pffile filewithname:filename data:imagedata];     [profile setobject:imagefile forkey:@"profileimagefile"]; }

also, this:

if(nametextfield.text.length==0 && titletextfield.text.length==0 && locationtextfield.text.length==0) 

it's doesn't appear connected anything?

you call twice in quick succession, , again right after file saves. there in method makes repetitive calls necessary?

[hud hide:yes];

your if statement doesn't appear connected anything:

if(nametextfield.text.length==0 && titletextfield.text.length==0 && locationtextfield.text.length==0) 

i'm assuming want:

if(nametextfield.text.length==0 && titletextfield.text.length==0 && locationtextfield.text.length==0) {      [hud hide:yes];      [profile saveinbackgroundwithblock:^(bool succeeded, nserror *error) {          if (error) {             [[[uialertview alloc] initwithtitle:@"profile information" message:@"fill in atleast 1 field" delegate:nil cancelbuttontitle:@"ok" otherbuttontitles:nil]show];              [hud hide:yes];         }         else {             // show success message             uialertview *alert = [[uialertview alloc] initwithtitle:@"" message:@"successfully updated profile" delegate:self cancelbuttontitle:@"ok" otherbuttontitles:nil, nil];             [alert show];              [hud hide:yes];              [self dismissviewcontrolleranimated:yes completion:nil];              [self performseguewithidentifier:@"profile" sender:self];         }     }]; }
