私は実際には私のプロジェクトの一つのためにこの機能を書いています。 XMLファイルを保存してキャッシュに書き込むために私が以前に使ったコードを共有します。
- (NSString *)XMLCacheFilePath
{
NSString *directory = @"/Library/Caches/XML/";
NSString *fileName = [@"file" stringByAppendingPathExtension:@"xml"];
// Setup directory path
NSString *homeDirectoryPath = NSHomeDirectory();
NSString *unexpandedDirectoryPath = [homeDirectoryPath stringByAppendingString:directory];
NSString *directoryPath = [NSString pathWithComponents:[NSArray arrayWithObjects:
[NSString stringWithString:[unexpandedDirectoryPath stringByExpandingTildeInPath]],
nil]];
// Setup file path
NSString *unexpandedFilePath = [directoryPath stringByAppendingPathComponent:fileName];
NSString *filePath = [NSString pathWithComponents:[NSArray arrayWithObjects:
[NSString stringWithString:[unexpandedFilePath stringByExpandingTildeInPath]],
nil]];
if (![[NSFileManager defaultManager] fileExistsAtPath:directoryPath isDirectory:nil]) {
NSError *error = [[NSError alloc] init];
[[NSFileManager defaultManager] createDirectoryAtPath:directoryPath
withIntermediateDirectories:YES
attributes:nil
error:&error];
}
return filePath;
}
- (void)saveXMLStringToDisk:(NSString *)xmlString
{
NSError *error;
[xmlString writeToFile:self.XMLCacheFilePath
atomically:YES
encoding:NSUTF8StringEncoding
error:&error];
}
- (NSString *)XMLStringFromDisk
{
NSString *XMLString = [NSString stringWithContentsOfFile:self.XMLCacheFilePath
encoding:NSUTF8StringEncoding
error:nil];
return XMLString;
}
