iOS 共享爬坑记
总体来说，还是有一点点小坑存在吧。
如果需要使用苹果的iCloud共享，那么你需要在开发者中心，将当前Bundle ID对应的iCloud权限给打开。这里有一点小坑，在选择Xcode5和Xcode6支持上，我先选择的Xcode6支持，但是不知道为何，我的Containers创建显示一直都是红色的，后来改成Xcode5支持的时候，突然变成黑色，具体的问题没有进行深入研究，有知道的朋友可以帮忙解答一下疑惑，谢谢。
OK，接下来，在我们的Xcode上需要开启iCloud权限。这个名字的格式就是iClou.[App的Bundle ID]
Xcode开启iCloud.png
然后在我们的info.plist文件中也需要进行设置相关信息。其中“Xin”就是你共享到iCloud上文件夹到名字。

OK，到了我们最喜欢的代码环节。
/// iCloud
- (void)iCloudAction {
//默认的icloud Documents容器的Indentifier
NSString * const ubiquityIndentifier = @"iCloud.com.face.magic";
NSURL *url = getDocumentUrlWithPath(nil);
NSArray *documents = @[@"4.pdf"];
for (NSString *documentName in documents)
{
BOOL t = [[NSFileManager defaultManager] copyItemAtPath:[[NSBundle mainBundle].resourcePath stringByAppendingPathComponent:documentName]
toPath:[url.path stringByAppendingPathComponent:documentName]
error:nil];
NSLog(@"isSuccess : %d",t);
}
}
//获取icloud Documents根文件夹或者子文件夹地址
NSURL* getDocumentUrlWithPath(NSString *path)
{
// NSString * const ubiquityIndentifier = @"iCloud.com.face.magic";
NSString * const ubiquityIndentifier = @"iCloud.com.face.magic";
NSURL *url = nil;
url = [[NSFileManager defaultManager] URLForUbiquityContainerIdentifier:ubiquityIndentifier];
NSLog(@"------url:%@",url);
if (url && path) {
url = [[url URLByAppendingPathComponent:@"Documents"] URLByAppendingPathComponent:path];
return url;
}else if(!path) {
// 如果不存在文件夹，则直接创建一个文件夹
if (![[NSFileManager defaultManager] fileExistsAtPath:[url URLByAppendingPathComponent:@"Documents"].path]) {
[[NSFileManager defaultManager] createDirectoryAtURL:[url URLByAppendingPathComponent:@"Documents"] withIntermediateDirectories:YES attributes:nil error:nil];
}
return [url URLByAppendingPathComponent:@"Documents"];
}else {
NSLog(@"Please check out that iCloud had been signed in");
return url;
}
return url;
}
这里有一个很重要的环节就是，如果没有Documents目录的话，创建一个，之前没有添加这个，文件一直说存在，但是就是没有展示出来，创建Documents后，文件已经能够正常展示了。
如果想要查看的话，可以通过iPhone手机的Files文件夹进行查看。
这里也可以在App内部查看：
- (void)presentDocumentPicker {
NSArray *documentTypes = @[@"public.content", @"public.text", @"public.source-code ", @"public.image", @"public.audiovisual-content", @"com.adobe.pdf", @"com.apple.keynote.key", @"com.microsoft.word.doc", @"com.microsoft.excel.xls", @"com.microsoft.powerpoint.ppt"];
UIDocumentPickerViewController *documentPickerViewController = [[UIDocumentPickerViewController alloc] initWithDocumentTypes:documentTypes
inMode:UIDocumentPickerModeOpen];
// documentPickerViewController.delegate = self;
[self presentViewController:documentPickerViewController animated:YES completion:nil];
}
这里我在放上之前写的有坑的代码，部分能够成功，不过有时会存在bug问题。
/// iCloud 导入2。- BUG：文件可能失败
- (void)iCloudImportAction {
NSLog(@"uploadDoc");
//文档名字
// NSString *fileName =@"1.txt";
NSString *fileName =@"4.pdf";
NSURL *url = [self getUbiquityContainerUrl:fileName];
// NSURL *url = getDocumentUrlWithPath(fileName);
MyDocument *doc = [[MyDocument alloc] initWithFileURL:url];
// UIDocument *doc = [[UIDocument alloc] initWithFileURL:url];

if (!myUrl) {

return nil;
}
}
NSURL *url = [myUrl URLByAppendingPathComponent:@"Documents"];

return url;
}

}
}
else {

}
}];
}

dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{

谨慎查看，避免踩坑。
