I get a weird issue while saving a file with writeToFile:options:error:
In the first case I get the following issue:
writeToFile failed with error Error Domain=NSCocoaErrorDomain Code=4 "The file “preferences.plist” doesn’t exist." UserInfo=0xa12c30 {NSFilePath=file:/Users/patrick/Desktop/Untitled.fef/preferences.plist, NSUnderlyingError=0xa0d130 "The operation couldn’t be completed. No such file or directory"}
But the file actually exist in that location. The file is stored in the app document file package.
CODE: (Subclass of NSDocument)
NSString *prefFile = [[[self fileURL] absoluteString] stringByAppendingPathComponent:@"preferences.plist"];
NSError *error;
BOOL succes = [[NSKeyedArchiver archivedDataWithRootObject:documentPreferences] writeToFile:prefFile options:0 error:&error];
if (!succes) {
NSLog(@"writeToFile failed with error %@", error);
}
Make sure when using any of the ...toFile
methods of various classes that you use a real path and not by mistake a file URL. You can tell these apart by looking at the path. If the path starts with file://
it can't be used. If it starts with a slash /
it is a regular file path. Still you might use NSFileManager
to check if the file exists.
As in your code instead of calling absoluteString
on self.fileURL
call path
.
