iphone - iOS模拟器认为文档目录是/var/root/Documents

Question

我试图读取模拟器中 Documents 目录中的所有文件，但我收到 Cocoa 错误 260。当我登录 [self applicationDocumentsDirectory] 时，它显示/var/root/Documents .有谁知道为什么会这样？它仅在我从命令行运行时发生。在模拟器本身中运行时，代码会为模拟器正确输出正确的文档文件夹。

更新 我现在看到路径“file://localhost/Users/MyUserName/Documents”。好奇怪……

- (NSString *)applicationDocumentsDirectory
{
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *basePath = ([paths count] > 0) ? [paths objectAtIndex:0] : nil;
    return basePath;
}

Answer 1

修复方法是 chmod -R 777 "/Users/MyUserName/Documents"然后将我的方法更改为:

- (NSString *)applicationDocumentsDirectory
{
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *basePath = ([paths count] > 0) ? [paths objectAtIndex:0] : nil;

    if (![[NSFileManager defaultManager] createDirectoryAtPath:basePath withIntermediateDirectories:YES attributes:nil error:NULL])
    {
        NSLog(@"Error: Create documents folder failed %@", basePath);
    }

    return basePath;
}
