You can use NSFileManager to check if the files already exist in Library folder, if not, move them. If move was successful, delete old file and return the new path, if not, return the old path. See below:
...
NSString *mySQLfilePath = [self getFilePathWithName:@"database.sqlite"];
...
- (NSString *)getFilePathWithName:(NSString *)filename
{
NSString *libPath = [NSHomeDirectory() stringByAppendingPathComponent:@"Library"];
NSString *docPath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];
NSString *fileLibPath = [libPath stringByAppendingPathComponent:filename];
NSString *fileDocPath = [docPath stringByAppendingPathComponent:filename];
if ([[NSFileManager defaultManager] fileExistsAtPath:fileLibPath]) {
// file already exists in Library folder
return fileLibPath;
} else if ([[NSFileManager defaultManager] fileExistsAtPath:fileDocPath]) {
// file exists in Documents folder, so move it to Library
NSError *error = nil;
BOOL moved = [[NSFileManager defaultManager] moveItemAtPath:fileDocPath toPath:fileLibPath error:&error];
NSLog(@"move error: %@", error);
// if file moved, you can delete old Doc file if you want
if (moved) [self deleteFileAtPath:fileDocPath];
// if file moved successfully, return the Library file path, else, return the Documents file path
return moved ? fileLibPath : fileDocPath;
}
// file doesn't exist
return nil;
}
- (void)deleteFileAtPath:(NSString *)filePath
{
if ([[NSFileManager defaultManager] isDeletableFileAtPath:filePath]) {
NSError *error = nil;
[[NSFileManager defaultManager] removeItemAtPath:filePath error:&error];
NSLog(@"delete error: %@", error);
} else {
NSLog(@"can not delete file: %@", filePath);
}
}
