How to download a .xls sheet from server and save it in iPhone memory, if spreadsheet is bigger in size then process took place in background.
Try this in any method.
NSURL *url=[NSURL URLWithString:#"http://en.wikipedia.org/wiki"]; //Your URL here
NSData *dbFile = [[NSData alloc] initWithContentsOfURL:url];
NSString *resourceDocPath = [[NSString alloc] initWithString:[[[[NSBundle mainBundle] resourcePath] stringByDeletingLastPathComponent]stringByAppendingPathComponent:#"Documents"]];
NSString *filePath = [resourceDocPath stringByAppendingPathComponent:#"Text_file.xls"];
[dbFile writeToFile:filePath atomically:YES];
I assume that you server doesn't require authentication

I am fairly new to iOS development, and am unable to store an SVG image in the documents directory of my app. I have access to the raw data and would like to store this in SVG format
The raw data is in NSData format.
NSData *rawData = [[NSData alloc] initWithBytes:ptr length:size];
rawData has the dowloaded file, please help me save this as an SVG. Any help appreciated, also I have been doing this for less than a week, sorry for any mistakes.
yeah, do this:
- (NSString *)writeDataToDocuments:(NSData *)data withFilename:(NSString *)filename {
NSString *docsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) firstObject];
NSString *filePath = [[NSString alloc] initWithString: [docsPath stringByAppendingPathComponent:filename]];
[data writeToFile:filePath atomically:YES];
return filePath;
}
the file path returned is where the SVG is now stored
so in your case it's
NSData *rawData = [[NSData alloc] initWithBytes:ptr length:size];
NSString *fileLocationString = [self writeDataToDocuments:rawData withFilename:#"example.svg"];
and now it's saved and you have the file path
I want to download a PDF file then open it in a webView. I searched about that then I found this issu. The accepted answer describes how to download and display the file. When I test it, I can not find the file in the Documents because it's stored inside my app. Also I don't think that the file is saved because the pdf is never shown in the webView even if I pass the filePath to be loaded. This is the code of the answer:
// Get the PDF Data from the url in a NSData Object
NSData *pdfData = [[NSData alloc] initWithContentsOfURL:[
NSURL URLWithString:#"http://www.example.com/info.pdf"]];
// Store the Data locally as PDF File
NSString *resourceDocPath = [[NSString alloc] initWithString:[
[[[NSBundle mainBundle] resourcePath] stringByDeletingLastPathComponent]
stringByAppendingPathComponent:#"Documents"
]];
NSString *filePath = [resourceDocPath
stringByAppendingPathComponent:#"myPDF.pdf"];
[pdfData writeToFile:filePath atomically:YES];
// Now create Request for the file that was saved in your documents folder
NSURL *url = [NSURL fileURLWithPath:filePath];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[webView setUserInteractionEnabled:YES];
[webView setDelegate:self];
[webView loadRequest:requestObj];
And this is what I see in the log:
libMobileGestalt MobileGestaltSupport.m:153: pid 2828 (my_app) does not have sandbox access for frZQaeyWLUvLjeuEK43hmg and IS NOT appropriately entitled
2017-08-01 10:29:06.882562+0100 my_app[2828:1334057] libMobileGestalt MobileGestalt.c:550: no access to InverseDeviceID (see <rdar://problem/11744455>)
What is the problem with what I did? And how can I put the downloaded file in the Documents app of my iPhone in order to be checked whenever the user want like any other PDF?
Sandbox path Error
NSString *resourceDocPath = [[NSString alloc] initWithString:[
[[[NSBundle mainBundle] resourcePath] stringByDeletingLastPathComponent]
stringByAppendingPathComponent:#"Documents"
]];
Please use your sandbox path instead of bundle path.
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
Hi in my application i have option of downloading a pdf file i have searched for that i got the code i have used its working fine in my mac i can see the downloaded pdf file. But the problem is if i download the same pdf in device where i can find the downloaded pdf file in device.
This is my code which i have used to download the pdf file.
NSData *pdfData = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:#"http://jesusredeems.com/mag/pdf/JRE-2014-03.pdf"]]; //Store the Data locally as PDF File
NSString *resourceDocPath = [[NSString alloc] initWithString:[[[[NSBundle mainBundle] resourcePath] stringByDeletingLastPathComponent] stringByAppendingPathComponent:#"Documents"]];
NSString *filePath = [resourceDocPath stringByAppendingPathComponent:#"11011.pdf"]; [pdfData writeToFile:filePath atomically:YES]; NSLog(#"%#",filePath);
If i print the filepath I'm getting like this.
/var/mobile/Applications/353C27AD-1E64-41CA-A429-16C2A20C8606/Documents/11011.pdf
In my mac i can see the downloaded file in that path but in my Ipad where i can see the downloaded pdf file please anyone tell where i have to find it.
Thanks.
Most likely your saving part is correct but try this anyways.
NSData *pdfData = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:#"http://jesusredeems.com/mag/pdf/JRE-2014-03.pdf"]];
NSArray* paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask ,YES);
NSString* documentsPath = [paths objectAtIndex:0];
NSString *destPath = [documentsPath stringByAppendingPathComponent:#"11011.pdf"];
[pdfData writeToFile:destPath atomically:YES];
And do this to retrieve it.
NSArray* paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask ,YES);
NSString* documentsPath = [paths objectAtIndex:0];
NSString* dataFile = [documentsPath stringByAppendingPathComponent:#"11011.pdf"];
NSData *pdfData3 = [NSData dataWithContentsOfFile:dataFile];
My app downloads a pdf and then on a button press brings it up in a new view.
I get the error:
-[NSURL initFileURLWithPath:]: nil string parameter'
After some troubleshooting I pinned the problem to somewhere in this code snippet. The path that is being pointed to is in the /Documents folder where the downloaded pdf is placed. Thus the document is not in the main bundle.
NSString *path = [[NSBundle mainBundle] pathForResource:PDFpathwithextension ofType:#"pdf"];
NSURL *url = [NSURL fileURLWithPath:path];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
Here's the download code:
//Start an NSURL connection to download from the remotepath
NSData *pdfData = [[NSData alloc] initWithContentsOfURL:remotepathURL];
//Store the Data locally as PDF File
NSString *resourceDocPath = [[NSString alloc] initWithString:[[[[NSBundle mainBundle] resourcePath] stringByDeletingLastPathComponent] stringByAppendingPathComponent:#"Documents"]];
NSString *filePath = [resourceDocPath stringByAppendingPathComponent:[newdata.ThirdPickerName stringByAppendingFormat:#".pdf"]];
pdfData writeToFile:filePath atomically:YES];
As NSURL is telling you, you've handed it nil instead of a valid path.
nil here means no such resource could be found by that name. Indeed, your question suggests you're well aware of this.
Since you claim your app already downloads a PDF, does it actually write that out to disk? If so, you should know where the resulting file is from doing that. If not, you first need to write the actual download code!
I have the following code. word.txt is in "Supporting Files":
NSString *filePath = [[NSBundle mainBundle] resourcePath];
filePath = [filePath stringByAppendingPathComponent:#"words.txt"];
NSData *data = [NSData dataWithContentsOfFile:filePath];
When I run using the simulator, data is not read properly but if I use the actual device, it works fine.
What is the problem?
This is how I do it and it seems to work for me:
NSString *filePath = [[NSBundle mainBundle] pathForResource:#"words" ofType:#"txt"];
NSData *data = [NSData dataWithContentsOfFile:filePath];
if (data) {
NSLog(#"DATA:%#",data);
}
And to set it to a string:
NSString* string = [[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding];
NSLog(#"WORDS:%#",string);
