我只是想将此图像上传到 iCloud。它一直给我错误“无法完成操作。不允许操作”。我直接从基于文档的应用程序编程指南中提取了这段代码，并且我相信我已经正确设置了我的所有证书、标识符、配置文件和权利。任何帮助将非常感激。这非常令人沮丧。

#import "docx.h"

@implementation docx

-(IBAction)test:(id)sender{

    NSURL *src = [NSURL URLWithString:@"/Users/rjm226/Desktop/jh.jpg"];
        NSLog(@"%@", src);

    NSURL *dest = NULL;

    NSURL *ubiquityContainerURL = [[[NSFileManager defaultManager]
                                    URLForUbiquityContainerIdentifier:nil]
                                   URLByAppendingPathComponent:@"Documents"];

    if (ubiquityContainerURL == nil) {
        NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys: NSLocalizedString(@"iCloud does not appear to be configured.", @""),
                              NSLocalizedFailureReasonErrorKey, nil];

        NSError *error = [NSError errorWithDomain:@"Application" code:404
                                         userInfo:dict];

        [self presentError:error modalForWindow:[self windowForSheet] delegate:nil didPresentSelector:NULL contextInfo:NULL];

        return;
    }

    dest = [ubiquityContainerURL URLByAppendingPathComponent:
            [src lastPathComponent]];

    //Move file to iCloud

    dispatch_queue_t globalQueue =
    dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);

    dispatch_async(globalQueue, ^(void) {

        NSFileManager *fileManager = [[NSFileManager alloc] init];

        NSError *error = nil;
        // Move the file.

        BOOL success = [fileManager setUbiquitous:YES itemAtURL:src
                                   destinationURL:dest error:&error];

        dispatch_async(dispatch_get_main_queue(), ^(void) {
            if (! success) {
                [self presentError:error modalForWindow:[self windowForSheet]
                          delegate:nil didPresentSelector:NULL contextInfo:NULL];
            }
        });
    });
}

This is insanely frustrating.

Welcome to iCloud. You'll get used to that feeling after a while. In the meantime though, you have other problems.

NSURL *src = [NSURL URLWithString:@"/Users/rjm226/Desktop/jh.jpg"];

This is not going to give you a valid URL, which is going to be a problem. What you need is:

NSURL *src = [NSURL fileURLWithPath:@"/Users/rjm226/Desktop/jh.jpg"];

That will give you a valid file:// URL.
