我正在尝试将一个文件夹从应用程序包复制到 iphone 文档目录,但它没有发生。
我用过这个代码
- (void)viewDidLoad
{
[super viewDidLoad];
NSString *sourcePath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"Photos"];
NSArray *paths1 = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths1 objectAtIndex:0];
NSError *error1;
NSArray *resContents = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:sourcePath error: &error1];
if (error1) {
NSLog(@"error1 : %@",error1);
}
[resContents enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop)
{
NSError* error;
if (![[NSFileManager defaultManager]
copyItemAtPath:[sourcePath stringByAppendingPathComponent:obj]
toPath:[documentsDirectory stringByAppendingPathComponent:obj]
error:&error])
NSLog(@"%@", [error localizedDescription]);
}];
}
也试过这种方法
- (void)viewDidLoad{
[self copyFolder];
}
- (void) copyFolder {
BOOL success1;
NSFileManager *fileManager1 = [NSFileManager defaultManager];
fileManager1.delegate = self;
NSError *error1;
NSArray *paths1 = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory1 = [paths1 objectAtIndex:0];
NSString *writableDBPath1 = [documentsDirectory1 stringByAppendingPathComponent:@"/Photos"];
if (![[NSFileManager defaultManager] fileExistsAtPath:writableDBPath1])
[[NSFileManager defaultManager] createDirectoryAtPath:writableDBPath1 withIntermediateDirectories:NO attributes:nil error:&error1];
NSString *defaultDBPath1 = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"Photos"];
NSLog(@"default path %@",defaultDBPath1);
success1 = [fileManager1 copyItemAtPath:defaultDBPath1 toPath:writableDBPath1 error:&error1];
if (!success1 )
{
NSLog(@"error1 : %@",error1);
} else {
}
}
- (BOOL)fileManager:(NSFileManager *)fileManager shouldProceedAfterError:(NSError *)error copyingItemAtPath:(NSString *)srcPath toPath:(NSString *)dstPath{
if ([error code] == 516) //error code for: The operation couldn’t be completed. File exists
return YES;
else
return NO;
}
它显示这个错误
Error Domain=NSCocoaErrorDomain Code=260 "The operation couldn’t be completed. (Cocoa error 260.)" UserInfo=0x8a39800 {NSUnderlyingError=0x8a385b0 "The operation couldn’t be completed. No such file or directory", NSFilePath=/Users/user/Library/Application Support/iPhone Simulator/7.0.3/Applications/FC7F93EE-CFB7-41CF-975B-2E3B18760202/app.app/Photos, NSUserStringVariant=( Folder )}
但是这是文件夹
最佳答案
Photos 看起来像是一组而不是文件夹引用。因此所有图像photo1.jpg
.. 等直接存储在您的资源包下。
路径 <resource_bundle>/Photos
不存在。要验证这一点,请转到应用程序 .app
.app->Right-click->Show Package Contents
不要将照片作为一个组添加,而是将其添加为文件夹引用,并在您的目标复制捆绑资源下确保添加整个文件夹。
希望对您有所帮助!
