NSSearchPathForDirectoriesInDomains麻烦（快速流失头发） [英] NSSearchPathForDirectoriesInDomains trouble (losing hair fast)

问题描述

我的秃顶很快，需要帮助！

我正在写一个需要访问目录的应用程序。我希望得到一个形式
/ Users / me / Library / Application Support / iPhone Simulator / User / Applications / 6958D21C-C94B-4843-9EF1-70406D0CA3A3 / Documents 的路径。然而，我的应用程序给我 /用户/我/图书馆/应用程序支持/ iPhone模拟器/用户/文档这是不是我想要的因为没有写入权限。

这里是我的代码彻底剥离的版本。请注意，您需要查看模拟器中的控制台以查看输出。我已经检查了我所知道的所有参考，并且没有成功改变这个行为。它是一些编译器选项？或者我必须在Info.plist中更改一些内容？任何人请... ...

更新：对于一些非常奇怪的原因，我的应用程序不是被沙箱。为什么？

文件DirTestAppDelegate.h

  #import< UIKit /UIKit.h> 
 
 @interface DirTestAppDelegate：NSObject< UIApplicationDelegate> 
 {
 UIWindow *窗口; b 
 
 
 
 
 
 
文件DirTestAppDelegate.m  p> 
 
 
  #importDirTestAppDelegate.h
 
 @implementation DirTestAppDelegate 
  - （void）applicationDidFinishLaunching： （UIApplication *）应用程序
 {
 NSArray * paths = NSSearchPathForDirectoriesInDomains（NSDocumentDirectory，NSUserDomainMask，YES）; 
 NSString * documentsDirectory = [paths objectAtIndex：0]; 
 NSLog（documentsDirectory）; 
 
 
 $ b  - （void）dealloc 
 {
 [super dealloc]; 
 
 @end 
  
 
 
解决方案
这是一个配置不正确的问题。花了几个小时来解决:-( 
 
I am getting bald quite quick and need help!

I am writing an app which needs to access directories. I was hoping to get a path of the form
/Users/me/Library/Application Support/iPhone Simulator/User/Applications/6958D21C-C94B-4843-9EF1-70406D0CA3A3/Documents.

However my app is giving me /Users/me/Library/Application Support/iPhone Simulator/User/Documents which is not what I want because have no write access.

Here is a thoroughly stripped down edition of my code. Note that you need to look at the console in the simulator to see the output. I have checked all the references I know and have no success to change the behaviour. Is it some compiler option? Or something I have to change in Info.plist? Anybody please...

Update: For some very strange reason my app is not being sandboxed. Why?

File DirTestAppDelegate.h
#import <UIKit/UIKit.h>

@interface DirTestAppDelegate : NSObject <UIApplicationDelegate> 
{
    UIWindow *window;
}

@end
File DirTestAppDelegate.m
#import "DirTestAppDelegate.h"

@implementation DirTestAppDelegate
- (void)applicationDidFinishLaunching:(UIApplication *)application 
{    
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSLog(documentsDirectory);
}


- (void)dealloc 
{
        [super dealloc];
}
@end

解决方案
It was an issue of the provisioning not set properly. Took hours to fix :-(
