1.单例

.h

@interface PackageManager : NSObject

@property (strong, nonatomic) NSString * documentPath;
@property (strong, nonatomic) NSString * cachesPath;

+ (instancetype)shareManager;

.m

static PackageManager * manager;

@implementation PackageManager

+ (instancetype)shareManager {
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        manager = [[self alloc]init];
    });
    return manager;
}

- (instancetype)init {
    if (self = [super init]) {
        self.cachesPath   = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES)[0];
        self.documentPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)[0];
    }
    return self;
}

2. 创建文件夹

.h

/**
 创建文件夹

 @param filePath 文件夹路径
 */
- (void)createFolderWithFile:(NSString *)filePath;

.m

- (void)createFolderWithFile:(NSString *)filePath {
    
    NSFileManager *fileManager = [NSFileManager defaultManager];
    BOOL isDir;
    BOOL isExit = [fileManager fileExistsAtPath:filePath isDirectory:&isDir];
    
    if (!isExit || !isDir)
    {
        [fileManager createDirectoryAtPath:filePath
               withIntermediateDirectories:YES
                                attributes:nil
                                     error:nil];
    }
}

3.删除文件夹

.h

/**
 删除文件夹

 @param filePath 文件夹路径
 */
- (void)removeFolderWithFile:(NSString *)filePath;

.m

- (void)removeFolderWithFile:(NSString *)filePath {
    NSFileManager *fileManager = [NSFileManager defaultManager];
    if ([fileManager fileExistsAtPath:filePath])
    {
        [fileManager removeItemAtPath:filePath error:nil];
    }
}

3.拷贝文件夹

.h

/**
 拷贝文件夹

 @param filePath 文件路径
 @param toPath 拷贝路径
 */
- (void)copyFlolderFrom:(NSString *)filePath to:(NSString *)toPath;

.m

- (void)copyFlolderFrom:(NSString *)filePath to:(NSString *)toPath {
    NSError *error;
    NSFileManager *fileManager = [NSFileManager defaultManager];
    
    if ([fileManager fileExistsAtPath:toPath])
    {
        [fileManager removeItemAtPath:toPath error:&error];
    }
    [fileManager copyItemAtPath:filePath toPath:toPath error:&error];
}

4.拷贝文件

.h

/**
 拷贝文件

 @param fileName 文件名称
 @param filePath 文件路径
 @param toPath 拷贝路径
 */
- (void)copyFillWithFile:(NSString *)fileName from:(NSString *)filePath to:(NSString *)toPath;

.m

- (void)copyFillWithFile:(NSString *)fileName from:(NSString *)filePath to:(NSString *)toPath {
    NSError *error;
    NSFileManager *fileManager = [NSFileManager defaultManager];
    NSString * fileToPath = [toPath stringByAppendingPathComponent:fileName];
    
    if ([fileManager fileExistsAtPath:fileToPath])
    {
        [fileManager removeItemAtPath:fileToPath error:&error];
    }
    [fileManager copyItemAtPath:[filePath stringByAppendingPathComponent:fileName]
                         toPath:toPath
                          error:&error];
}

5.移动文件夹

.h

/**
 移动文件夹

 @param filePath 文件路径
 @param toPath 移动路径
 */
- (void)moveFolderFrom:(NSString *)filePath to:(NSString *)toPath;

.m

- (void)moveFolderFrom:(NSString *)filePath to:(NSString *)toPath {
    NSError *error;
    NSFileManager *fileManager = [NSFileManager defaultManager];
    if ([fileManager fileExistsAtPath:toPath])
    {
        [fileManager removeItemAtPath:toPath error:&error];
    }
    [fileManager moveItemAtPath:filePath toPath:toPath error:&error];
}

6.移动文件

.h

/**
 移动文件

 @param fileName 文件名
 @param filePath 文件路径
 @param toPath 移动路径
 */
- (void)moveFillWithFill:(NSString *)fileName from:(NSString *)filePath to:(NSString *)toPath;

.m

- (void)moveFillWithFill:(NSString *)fileName from:(NSString *)filePath to:(NSString *)toPath {
    
    NSError *error;
    NSFileManager *fileManager = [NSFileManager defaultManager];
    NSString * fileToPath = [toPath stringByAppendingPathComponent:fileName];
    
    if ([fileManager fileExistsAtPath:fileToPath])
    {
        [fileManager removeItemAtPath:fileToPath error:&error];
    }
    [fileManager moveItemAtPath:[filePath stringByAppendingPathComponent:fileName]
                         toPath:toPath
                          error:&error];
}
