Hi, i'm trying to save the contents of an NSTextView to an RTFD file and then open it again later and read the contents into another NSTextView. The file saves fine (i can open it in terminal and all of the formatting seems to be in tact) and using this line:

Code:
NSData *rtfContents = [NSData dataWithContentsOfFile:[selectedPath stringByAppendingString:@".desc"]];

i can read the file fine (confirmed using [rtfContents length]) but when i call this line:

Code:
[description initWithRTFD:rtfContents documentAttributes:NULL];

it doesn't read rtfContents... when i call [description length] it's 0. So, my question is, how do i get it to read the NSData object? Is there something i should put in documentAttributes? (and if so, how do i format that?)


Thanks,
Max

What kind of object is description?
Also, are these lines both in the same method? If not you may have some retainment issues.

yeah, they're both in the same method. description is an NSAttributedString.

initWithRTFD is in 'NSAttributedString Additions' so is there anything special i have to do to get that functionality?

It looks like the culprit is right there:

Code:
[description initWithRTFD:rtfContents documentAttributes:NULL];

You're discarding the return value of the init method, and thus not receiving the attributed string. This is why allocation and initialization should always be combined into one line--otherwise it's easy to forget that init isn't guaranteed to return the same object you sent the message to.

nope, that's not it either... I've tried it both ways and neither work

edit: here's the initWithRTFD entry from the application kit reference:

initWithRTFD:documentAttributes:



- (id)initWithRTFDNSData *)rtfdData documentAttributesNSDictionary **)docAttributes
Initializes a new NSAttributedString by decoding the stream of RTFD commands and data contained in rtfdData. Also returns by reference in docAttributes a dictionary containing document-level attributes described in �Constants�. docAttributes may be NULL, in which case no document attributes are returned. Returns self, or nil if rtfData can�t be decoded.

so the line:

Code:
NSAttributedString *description = [description initWithRTFD:rtfContents documentAttributes:NULL];

would cause description to be either self or nil, no? in which case, the size is still 0, so it must be returning nil.

[Gametes]

NSAttributedString *description = [[NSAttributedString alloc] initWithRTFD:rtfContents documentAttributes:NULL];

No?

No?

THANK YOU! that worked! i'm somewhat new to Obj-C and i couldn't figure out for the life of me why it didn't work. thank you so much
