IOS沙盒目录

一、Object-C

#pragma mark 获取应用沙盒根路径-(void)dirHome {    NSString *dirHome=NSHomeDirectory();    NSLog(@"app_home: %@",dirHome);}#pragma mark 获取Documents目录路-(NSString *)dirDoc {    //[NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);    NSString *documentsDirectory = [paths objectAtIndex:0];    NSLog(@"app_home_doc: %@",documentsDirectory);    return documentsDirectory;}#pragma mark 获取Library目录路径-(void)dirLib {    //[NSHomeDirectory() stringByAppendingPathComponent:@"Library"];    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES);    NSString *libraryDirectory = [paths objectAtIndex:0];    NSLog(@"app_home_lib: %@",libraryDirectory);}#pragma mark 获取Cache目录路径-(void)dirCache {    NSArray *cacPath = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);    NSString *cachePath = [cacPath objectAtIndex:0];    NSLog(@"app_home_lib_cache: %@",cachePath);}#pragma mark 获取Tmp目录路径-(void)dirTmp {    //[NSHomeDirectory() stringByAppendingPathComponent:@"tmp"];    NSString *tmpDirectory = NSTemporaryDirectory();    NSLog(@"app_home_tmp: %@",tmpDirectory);}

 

二、Swift

  // HomeDirectory:应用程序的程序包目录，包含应用程序的本身。由于应用程序必须经过签名，所以您在运行时不能对这个目录中的内容进行修改，否则可能会使应用程序无法启动。    let homeDir = NSHomeDirectory();    println("HomeDirectory:\(homeDir)")    // DocumentDirectory:应用中用户数据可以放在这里，iTunes备份和恢复的时候会包括此目录    let documents = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.UserDomainMask, true)    let docDir = documents.first as! String    println("DocumentDirectory:\(docDir)")    // CachesDirectory:存放缓存文件，iTunes不会备份此目录，此目录下文件不会在应用退出删除    let caches = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.CachesDirectory, NSSearchPathDomainMask.UserDomainMask, true)    let cachesDir = caches.first as! String    println("CachesDirectory:\(cachesDir)")    // TemporaryDirectory：存放临时文件，iTunes不会备份和恢复此目录，此目录下文件可能会在应用退出后删除    let tmpDir = NSTemporaryDirectory();    println("TemporaryDirectory:\(tmpDir)")    // 获取应用程序程序包中资源文件路径的方法：    // 例如获取程序包中一个图片资源（apple.png）路径的方法：代码中的mainBundle类方法用于返回一个代表应用程序包的对象。    if let imagePath = NSBundle.mainBundle().pathForResource("apple", ofType: "png") {        let appleImage = UIImage(contentsOfFile: imagePath)    }
