ios 擷取各路徑

因為各種需求，需要擷取的路徑不一致，故寫下這文章，以作備忘。

- (NSString *)getDocumentPath{    NSString *path = nil;        // Method 1    NSArray *pathsArray = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);    path = [pathsArray objectAtIndex:0];        // Method 2//    path = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];        return path;}- (NSString *)getAppPath{    NSString *path = nil;        path = NSHomeDirectory();        return path;}

// tmp 目錄我們可以在裡面寫入一些程式運行時需要用得資料，裡面寫入得資料在程式退出後會沒有。- (NSString *)getTmpPath{    NSString *path = nil;        path = NSTemporaryDirectory();        return path;}- (NSString *)getAppPackagePath{    NSString *path = nil;        // Method 1    path = [[NSBundle mainBundle] resourcePath];        // Method 2        return path;}- (NSString *)getFilePath{    NSString *path = nil;        NSFileManager *fileManager = [NSFileManager defaultManager];NSURL *pathURL = [fileManager URLForDirectory:NSApplicationSupportDirectory inDomain:NSUserDomainMask appropriateForURL:nil create:YES error:NULL];    path = [pathURL path];        return path;}
