在哪里存储创建的 PDF 文件？

发布于 2024-12-21 03:54:35 字数 709 浏览 1 评论 0原文

出现以下错误：

CGDataConsumerCreateWithFilename: failed to open `/name' for writing: Permission denied.

使用此代码（不是我的）：

- (void)createPDFWithName
{
//NSURL * newFilePath = [[NSURL alloc] initFileURLWithPath:name];
NSString * newFilePath = @"name";

CGRect page = CGRectMake(0, 0, 300, 300);

NSDictionary * metaData = nil;

if (!UIGraphicsBeginPDFContextToFile(newFilePath, page, metaData )) {
    NSLog(@"error creating PDF context");
    return;
}

UIGraphicsBeginPDFPage();
[self.tableView.layer renderInContext:UIGraphicsGetCurrentContext()];
UIGraphicsEndPDFContext();
}

那么：我应该在哪里存储此 PDF 文件？我尝试了 NSBundle MainBundle ，但它也不起作用。

谢谢你！

Got the following error:

CGDataConsumerCreateWithFilename: failed to open `/name' for writing: Permission denied.

With this code (not mine):

- (void)createPDFWithName
{
//NSURL * newFilePath = [[NSURL alloc] initFileURLWithPath:name];
NSString * newFilePath = @"name";

CGRect page = CGRectMake(0, 0, 300, 300);

NSDictionary * metaData = nil;

if (!UIGraphicsBeginPDFContextToFile(newFilePath, page, metaData )) {
    NSLog(@"error creating PDF context");
    return;
}

UIGraphicsBeginPDFPage();
[self.tableView.layer renderInContext:UIGraphicsGetCurrentContext()];
UIGraphicsEndPDFContext();
}

So: Where should I store this PDF-File? I tried the NSBundle MainBundle thing and it did not work either.

Thank you!

您应该了解文件系统上可以创建文件的各个位置。其中之一是文档路径，示例如下。

- (NSString *)documentPath {
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentPath = ([paths count] > 0) ? [paths objectAtIndex:0] : nil;
    return documentPath;
}

NSString * newFilePath = [[self documentPath] stringByAppendingPathComponent:@"name.pdf"];

You should read about the various places on the file system that you can create files. One of these is the documents path, an example is below.

- (NSString *)documentPath {
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentPath = ([paths count] > 0) ? [paths objectAtIndex:0] : nil;
    return documentPath;
}

NSString * newFilePath = [[self documentPath] stringByAppendingPathComponent:@"name.pdf"];
