下面是我封装的方法，想调用那个的时候直接调用，方便快捷

#import "SendBoxPaths.h"
@implementation SendBoxPaths
//获取沙盒的主路径
+ (NSString*)homePath{
    return NSHomeDirectory();
}
//获取documents路径
+ (NSString*)documentsPath{
    NSArray* documentsArray = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    return documentsArray.firstObject;
}
//获取Library路径
+ (NSString*)libraeyPath{
    NSArray* libraryArray = NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES);
    return libraryArray.firstObject;
}
//获取Library/caches路径
+ (NSString*)cachesPath{
    NSArray* cachesArray = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    return cachesArray.firstObject;
}
//获取Library/preferences路径
+ (NSString*)preferencesPath{
//    NSArray* libraryArray = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString* preferences = [[self libraeyPath] stringByAppendingString:@"/preferences"];
    return preferences;
}
//获取tmp路径
+ (NSString*)tmpPath{
    return NSTemporaryDirectory();
}
