Creating a folder that already exists (iOS)
I went through this already for Android, and I learned that to create a folder that might already exists I only need to check the exception as follows:
catch (CreateFolderErrorException err) { if(...
In this case, you'd get a DBFILESCreateFolderError in your cfError variable, containing a "conflict" DBFILESWriteError in the path field.
Here's an example of how you'd detect the different error cases, picking out the conflict error:
[[client.filesRoutes createFolder:@"/testfolder"] response:^(DBFILESFolderMetadata *result, DBFILESCreateFolderError *cfError, DBError *error) {
if (result) {
NSLog(@"Create folder succeeded:");
NSLog(@"%@", result);
} else {
NSLog(@"Create folder failed:");
if (cfError) {
NSLog(@"The error is a create folder error.");
if ([cfError isPath]) {
NSLog(@"The error is a path error.");
if (cfError.path.isConflict) {
NSLog(@"Couldn't create folder because there was something in the way.");
} else {
NSLog(@"Other create folder path error:");
NSLog(@"%@", cfError.path);
}
}
} else if (error) {
NSLog(@"The error is a generic error.");
NSLog(@"%@", error);
}
}
}];(Apologies for the poor formatting.)

Dropbox StaffThat would also be a path conflict error. The conflict error itself just means that something is already at the path. You can then check that DBFILESWriteConflictError to see if it was a file or folder, e.g. to expand on my last example:
[[client.filesRoutes createFolder:@"/testfolder"] response:^(DBFILESFolderMetadata *result, DBFILESCreateFolderError *cfError, DBError *error) {
if (result) {
NSLog(@"Create folder succeeded:");
NSLog(@"%@", result);
} else {
NSLog(@"Create folder failed:");
if (cfError) {
NSLog(@"The error is a create folder error.");
if ([cfError isPath]) {
NSLog(@"The error is a path error.");
if (cfError.path.isConflict) {
NSLog(@"Couldn't create folder because there was something in the way.");
if (cfError.path.conflict.isFolder) {
NSLog(@"Couldn't create folder because a folder already exists there.");
} else if (cfError.path.conflict.isFile) {
NSLog(@"Couldn't create folder because a file already exists there.");
} else {
NSLog(@"Other create folder path conflict error:");
NSLog(@"%@", cfError.path.conflict);
}
} else {
NSLog(@"Other create folder path error:");
NSLog(@"%@", cfError.path);
}
}
} else if (error) {
NSLog(@"The error is a generic error.");
NSLog(@"%@", error);
}
}
}];
