第三方应用调用系统文件app，并下载文件。
配置如下
1：证书文件配置
在Identifiers下创建你的iCloud Containers配置，点击“+”创建
2：在Identifiers下选择你要添加icloud的boundid把icloud配置勾选上既可
3：打开工程中的配置如下
image
4：可选配置
在info.plist中添加如下两个配置
Supports opening documents in place
Application supports iTunes file sharing
结果都为YES
设置完以后，会在文件app中有一个和你工程名相同的文件夹出现。
5：打开文件app
- (void)presentDocumentCloud {
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];
}
遵守代理如下
<UIDocumentPickerDelegate, UIDocumentInteractionControllerDelegate>
选择文件事件
#pragma mark - UIDocumentPickerDelegate
- (void)documentPicker:(UIDocumentPickerViewController *)controller didPickDocumentAtURL:(NSURL *)url {
NSArray *array = [[url absoluteString] componentsSeparatedByString:@"/"];
NSString *fileName = [array lastObject];
fileName = [fileName stringByRemovingPercentEncoding];
NSLog(@"--->>>>%@",fileName);
if ([iCloudManager iCloudEnable]) {
[iCloudManager downloadWithDocumentURL:url callBack:^(id obj) {
NSData *data = obj;
UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"icloud" message:@"写入沙河" delegate:nil cancelButtonTitle:@"取消" otherButtonTitles:@"确定", nil];
[alert show];
//写入沙盒Documents
NSString *path = [NSHomeDirectory() stringByAppendingString:[NSString stringWithFormat:@"/Documents/%@",fileName]];
[data writeToFile:path atomically:YES];
}];
}
}
6：判断icloud是否可用
+ (BOOL)iCloudEnable {
NSFileManager *manager = [NSFileManager defaultManager];
NSURL *url = [manager URLForUbiquityContainerIdentifier:nil];
if (url != nil) {
return YES;
}
NSLog(@"iCloud 不可用");
UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"icloud" message:@"iCloud 不可用" delegate:nil cancelButtonTitle:@"取消" otherButtonTitles:@"确定", nil];
[alert show];
return NO;
}
