我需要在其中创建文件夹Cloud
并将我的.txt
文本文件保存到该文件夹中。
所以我用以下代码创建了文件夹AppDelegate
NSURL *ubiq = [[NSFileManager defaultManager] URLForUbiquityContainerIdentifier:nil];
NSError *error = nil;
if(ubiq)
{
NSFileManager *fm = [NSFileManager defaultManager];
NSURL *rootURL = [fm URLForUbiquityContainerIdentifier:nil];
NSURL *newFolder = [NSURL URLWithString:@"Notes" relativeToURL:rootURL];
[fm createDirectoryAtURL:newFolder withIntermediateDirectories:YES attributes:nil error:&error];
if(error)
{
NSLog(@"Error");
}
else
{
NSLog(@"NO Error");
}
}
我测试后,它显示没有错误。所以我假设它在 iCloud 中创建了 Notes 文件夹。
但是,当我使用以下代码将文本文档保存到该文件夹中时,它显示错误并且不保存。
NSString *file = [NSString stringWithFormat:@"%@.txt",fileName];
NSURL *ubiq = [[NSFileManager defaultManager]
URLForUbiquityContainerIdentifier:nil];
NSURL *ubiquitousPackage =
[[[ubiq URLByAppendingPathComponent:@"Documents"] URLByAppendingPathComponent:@"Notes"]
URLByAppendingPathComponent:file];
Note *doc = [[Note alloc] initWithFileURL:ubiquitousPackage];
[doc saveToURL:[doc fileURL] forSaveOperation:UIDocumentSaveForCreating completionHandler:^(BOOL success) {
if (!success)
{
NSLog(@"Error");
}
else
{
doc.noteContent = self.txtView.text;
[doc updateChangeCount:UIDocumentChangeDone];
}
}];
错误信息是
Foundation called mkdir("/private/var/mobile/Library/Mobile Documents/35QNLTQU29~com~myapp~iCloudTest/Documents/Notes/(A Document Being Saved By iCloudTest)"), it didn't return 0, and errno was set to 2.
我该如何解决?
