NSUrl fileURLWithPath 返回奇怪的中文符号 [英] NSUrl fileURLWithPath returns strange chinese signs

问题描述

我的文档文件夹有一个 NSString 路径.

I have an NSString path to my Documents folder.

NSString* stringURL = @"/var/mobile/Applications/5667FADC-F848-40CF-A309-
7BFE598AE6AB/Library/Application Support/MyAppDirectory";

当我用

 NSURL* url = [NSURL fileURLWithPath:stringUrl];

和 NSLog(@"Created URL: %@",url);，我得到了一些奇怪的结果:

and NSLog(@"Created URL: %@",url);, i get some strange result:

为什么会这样?我做错了什么?

Why is this so ? What am I doing wrong ?

推荐答案

基于您从 上一个问题;这是因为使用 stringByAddingPercentEscapesUsingEncoding 会生成一个类似 printf 的格式化字符串，其中包含 %20S(Application Support 转换为 %20)，混淆了 NSLog():

Based on the answer you accepted from a previous question; it's because the use of stringByAddingPercentEscapesUsingEncoding will generate a printf-like formatting string containing %20S (the space between Application Support is converted to %20), which confuses NSLog():

NSURL *url = [NSURL fileURLWithString:[stringURL stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding] isDirectory:YES];
NSLog(url);

使用 NSLog("@%", url) 避免这个错误.

use NSLog("@%", url) to avoid this error.
