I make and app that the people download content and they can access it offline, it likes a catalogue. But Apple reject it because it baking up in iCloud i I'm doing the following but it seems not working.
Funciones.m
+ (BOOL)addSkipBackupAttributeToItemAtURL:(NSURL *)URL {
const char* filePath = [[URL path] fileSystemRepresentation];
const char* attrName = "com.apple.MobileBackup";
u_int8_t attrValue = 1;
int result = setxattr(filePath, attrName, &attrValue, sizeof(attrValue), 0, 0);
return result == 0;
}
Update.m
- (void)updateImg:(NSString *)tipo {
//tomamos el ultimo update
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSTimeInterval time = [defaults doubleForKey:#"lastUpdate"];
NSLog(#"%f", time);
CatalogoAppDelegate *app = [[UIApplication sharedApplication] delegate];
NSString *post = [NSString stringWithFormat:#"lastUpdate=%f", time];
NSData *postData = [post dataUsingEncoding:NSISOLatin1StringEncoding allowLossyConversion:NO];
NSMutableURLRequest *urlRequest = [[[NSMutableURLRequest alloc] init] autorelease];
NSString *url = [NSString stringWithFormat:#"%#iPhone/update%#Img.php", app.serverUrl, tipo];
[urlRequest setURL:[NSURL URLWithString:url]];
[urlRequest setHTTPMethod:#"POST"];
[urlRequest setHTTPBody:postData];
NSData *urlData;
NSURLResponse *response;
NSError *error;
urlData = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:&response error:&error];
if(urlData) {
NSString *aStr = [[[NSString alloc] initWithData:urlData encoding:NSUTF8StringEncoding]autorelease];
//NSLog(#"%#: %#", tipo, aStr);
NSArray *temp = [aStr componentsSeparatedByString:#";"];
//Direccionl Local de la APP
NSString *docDir = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
for (int i=0; i<[temp count]; i++) {
NSString *tempImg = [NSString stringWithFormat:#"%#", [temp objectAtIndex:i]];
//NSLog(#"%#", tempImg);
//pedimos cada url
NSURL *tempURL = [NSURL URLWithString:[NSString stringWithFormat:#"%#images/%#/%#", app.serverUrl, tipo, tempImg]];
//[Funciones addSkipBackupAttributeToItemAtURL:tempURL];
UIImage *image = [[UIImage alloc] initWithData:[NSData dataWithContentsOfURL:tempURL]];
NSLog(#"%#images/%#/%#", app.serverUrl, tipo, tempImg);
NSString *pngFilePath = [NSString stringWithFormat:#"%#/%#", docDir, tempImg];
NSData *data1 = [NSData dataWithData:UIImagePNGRepresentation(image)];
[data1 writeToFile:pngFilePath atomically:YES];
NSURL *backUrl = [NSURL fileURLWithPath:pngFilePath];
[Funciones addSkipBackupAttributeToItemAtURL:backUrl];
}
}
[self performSelectorInBackground:#selector(finUpdate) withObject:nil];
}
Any idea what I am doing wrong?
Thanks
setxattr provides a result indicating success or an error, and Apple's addSkipBackupAttributeToItemAtURL: method checks for an error and passes this information back to your code. Your code simply ignores it. Start by determining if it's returning an error or not.
Maybe it's because your app is compatible with iOS 5.0.
Do not backup variable is only available since 5.1. Details here http://developer.apple.com/library/ios/#qa/qa1719/_index.html#//apple_ref/doc/uid/DTS40011342

I'm trying to implement this example link of a DocuSign service that download an envelope document, but when the execution arrive to this line in step 3:
NSMutableString *jsonResponse = [[NSMutableString alloc] initWithData:oResponseData encoding:NSUTF8StringEncoding];
jsonResponse is nil and when I open the document, it has a lot of strange characters and I can't read it.
My code for downloadind is the following:
NSString *url = #"https://demo.docusign.net/restapi/v2/accounts/373577/envelopes/08016140-e4dc-4697-8146-f8ce801abf92/documents/1";
NSMutableURLRequest *documentsRequest = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:url]];
[documentsRequest setHTTPMethod:#"GET"];
[documentsRequest setURL:[NSURL URLWithString:url]];
[documentsRequest setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[documentsRequest setValue:[self jsonStringFromObject:authenticationHeader] forHTTPHeaderField:#"X-DocuSign-Authentication"];
NSError *error1 = [[NSError alloc] init];
NSHTTPURLResponse *responseCode = nil;
NSData *oResponseData = [NSURLConnection sendSynchronousRequest:documentsRequest returningResponse:&responseCode error:&error1];
NSMutableString *jsonResponse = [[NSMutableString alloc] initWithData:oResponseData encoding:NSUTF8StringEncoding];
if([responseCode statusCode] != 200){
NSLog(#"Error sending %# request to %#\nHTTP status code = %i", [documentsRequest HTTPMethod], url, [responseCode statusCode]);
NSLog( #"Response = %#", jsonResponse );
return;
}
// download the document to the same directory as this app
NSString *appDirectory = [[[NSBundle mainBundle] bundlePath] stringByDeletingLastPathComponent];
NSMutableString *filePath = [NSMutableString stringWithFormat:#"%#/%#", appDirectory, #"eee"];
[oResponseData writeToFile:filePath atomically:YES];
NSLog(#"Envelope document - %# - has been downloaded to %#\n", #"eee", filePath);
If no data is coming back from
NSMutableString *jsonResponse = [[NSMutableString alloc] initWithData:oResponseData encoding:NSUTF8StringEncoding];
then that means oResponseData is most likely nil which means the URL is not being constructed correctly for each envelope document. Are you doing step 2 in the sample that you linked to, where it first retrieves the envelopeDocuments information about the envelope, then it dynamically builds each unique document uri in preparation of downloading each one.
Instead of hardcoding your URL you should dynamically retrieve the envelopeDocuments data, then build each document uri dynamically then your response data will not be nil. Here's the full working sample:
- (void)getDocumentInfoAndDownloadDocuments
{
// Enter your info:
NSString *email = #"<#email#>";
NSString *password = #"<#password#>";
NSString *integratorKey = #"<#integratorKey#>";

im new with objective-c. I have problem with memory leaking when developing iphone app. Leaking utility in Xcode shows that leaking problem with 'combArr'->'results' object. There is my function which parsing json from url and returns NSArray:
- (NSArray *)getListing2:(NSString *)item
from:(int)country {
//sending post request with some params
NSString *post = [#"product=" stringByAppendingString:item];
NSString *countryStr = [NSString stringWithFormat:#"&country=%d", country];
post = [post stringByAppendingString:countryStr];
NSData *postData = [post dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%d", [postData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
NSString *url = [prefs objectForKey:#"urlToApi"];
url = [url stringByAppendingString:#"/get-items/"];
[request setURL:[NSURL URLWithString:url]];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
[request release];
//receiving json
NSString *jsonString = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding];
SBJsonParser *json = [[SBJsonParser alloc] init];
NSError *error = nil;
//parsing json to nsdictionary
NSDictionary *results = [[NSDictionary alloc] initWithDictionary:[json objectWithString:jsonString error:&error]];
[json release];
[jsonString release];
//generate array of items
NSMutableArray *listOfItems = [[NSMutableArray alloc] init];
for (int i = 0; i < [[results objectForKey:#"data"] count]; i++) {
[listOfItems addObject:[[results objectForKey:#"data"] objectForKey:[NSString stringWithFormat:#"%d", i]]];
}
//saving items array and count info object into one array
NSArray * returnArr = [[[NSArray arrayWithObjects:listOfItems, [results valueForKey:#"count_info"], nil] retain] autorelease];
[listOfItems release];
[results release];
return returnArr;
}
And i executing this function here:
myApi *itemsApi = [[myApi alloc] init];
NSArray *combArr = [[izdApi getListing2:item from:countryId] retain];
[itemsApi release];
listOfItems = [[combArr objectAtIndex:0] retain];
if([listOfItems count] > 0){
priceArr = [[combArr objectAtIndex:1] retain];
}
else{
totalCount = 0;
}
[combArr release];
Thank you for helping
Every time you allocate memory, you must release it. (alloc, copy, retain).
You are releasing myApi, not itemsApi. Try this...
myApi *itemsApi = [[itemsApi alloc] init];
NSArray *combArr = [[izdApi getListing2:item from:countryId] retain];
[itemsApi release];
listOfItems = [[combArr objectAtIndex:0] retain];
if([listOfItems count] > 0){
priceArr = [[combArr objectAtIndex:1] retain];
}
else{
totalCount = 0;
}
[combArr release];
If you are using Xcode 4, Try turning on ARC. In short, ARC handles the releasing of all memory. A little burden off your shoulders and one less thing for you to worry about.
My NSXMLParsing is not working because of "&" character.. my code s below .any help please ?
NSString *myRequestString = [NSString stringWithFormat:#"http://abc.com/def/webservices/aa.php?family_id=%d",self.passFamilyId];
//NSLog(#"Requested Service = %#",myRequestString);
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:myRequestString]];
[request setHTTPMethod: #"POST" ];
NSData *downloadedData = [ NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *str = [[NSString alloc] initWithData:downloadedData encoding:NSASCIIStringEncoding];
//NSString *contentString = [str stringByReplacingOccurrencesOfString:#"&" withString:#"&"];
NSData * data=[str dataUsingEncoding:NSUTF8StringEncoding];
//NSLog (#"string is :%#" ,str);
NSXMLParser *xmlParser = [[NSXMLParser alloc] initWithData:data];
// Call the XMLParsers's initXMLParse method.
ClientDetailXmlParser *parser = (ClientDetailXmlParser*)[[ClientDetailXmlParser alloc] initXMLParser];
[xmlParser setDelegate:parser];
BOOL success = [xmlParser parse];
// Check for XML parsing.
if(success)
{
NSLog(#"No Errors in clientDetailXml.xml");
}
else
{
NSLog(#"Error Error Error in clientDetailXml.xml!!!");
}
[parser release];
parser = nil;
if (objClientAddUpdate != nil) {
[objClientAddUpdate createBubbleList];
}
Replace
NSString *str = [[NSString alloc] initWithData:downloadedData encoding:NSASCIIStringEncoding];
//NSString *contentString = [str stringByReplacingOccurrencesOfString:#"&" withString:#"&"];
NSData * data=[str dataUsingEncoding:NSUTF8StringEncoding];
With:
NSString *str = [[NSString alloc] initWithData:downloadedData encoding:NSASCIIStringEncoding];
NSString *contentString = [str stringByReplacingOccurrencesOfString:#"&" withString:#"&"];
NSData * data=[contentString dataUsingEncoding:NSUTF8StringEncoding];
Very similar to sepehr-mahmoudian's answer, but instead of replace any & you should really just replace & characters that are unescaped, to do this you can use a regexp:
NSString *str = [[NSString alloc] initWithData:downloadedData encoding:NSASCIIStringEncoding];
//NSString *contentString = [str stringByReplacingOccurrencesOfString:#"&" withString:#"&"];
NSData * data=[str dataUsingEncoding:NSUTF8StringEncoding];
With:
NSString *str = [[NSString alloc] initWithData:downloadedData encoding:NSASCIIStringEncoding];
NSRange searchedRange = NSMakeRange(0, [str length]);
NSString *pattern = #"&(?!(#[0-9]{2,4}|[A-z]{2,6});)";
NSError *error = nil;
NSRegularExpression* regex = [NSRegularExpression regularExpressionWithPattern:pattern options:0 error:&error];
str = [regex stringByReplacingMatchesInString:str options:0 range:searchedRange withTemplate:#"&"];
NSData *data = [str dataUsingEncoding:NSUTF8StringEncoding];
Here's what worked for me:
NSString *response = [[NSString alloc]initWithData:dataResponse encoding:NSUTF8StringEncoding];
NSString *newResponse = [response stringByReplacingOccurrencesOfString:#"&:" withString:#"AND"];
NSData *dataObj = [newResponse dataUsingEncoding:NSUTF8StringEncoding];
If I replaced it with symbol '&', the response would be correct, but it would throw parsing error: 68. So I had to use 'and'.
I have written code like this but I can't understand how to find if the data is present or not in the URL. Can anyone help me in solving this problem?
Note: This code terminates when the loop is entering the second condition. That is where it's terminating.
-(void)getdetails
{
NSLog(#"in get details");
NSURL *jsonurl=[NSURL URLWithString:#"http://www.myappdemo.com/checkout/services/getonlineusers.php"];

NSData *serverReply = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];

if([replyString isEqualToString:#"Invalid."]){ // i have not set the php code to output "invalid" so this will not work for now ...

}
else {
NSMutableArray *tempArray =[replyString JSONValue];
int count=0;
self.temparray=tempArray;
for(int i=0;i<[tempArray count];i++)
{
///////Here in this loop when it is entering it is terminating /////////
NSDictionary *dict=[tempArray objectAtIndex:i];
NSLog(#"DICT is %#",dict);
NSString *string=[dict objectForKey:#"profilepic"];

NSFileManager *fileManager = [NSFileManager defaultManager];
BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:url];
NSLog(#"url is %#",url);
NSData *data=[NSData dataWithContentsOfURL:url];
if(!(data==nil))
{
NSLog(#"data is there");
UIImage *image=[[UIImage alloc]initWithData:data];
[self.array addObject:image];
[image release];
}
else {
/*
NSLog(#"if data is null condition block");
UIImage *image=[[UIImage alloc]init];
[self.array addObject:image];
[image release];
*/
}
count=count+1;
NSLog(#"count is %d",count);
}
}
[replyString release];
}
Where does the app terminate and what is the exception? Have you stepped through to see what the array object looks like during each iteration? Is it failing at NSData initWithContentsOfURL? Why don't you issue that as a separate synchronous request and test to see if you got a response?
Regarding your first (and any subsequent) synchronous request, it would probably be good to add a check to ensure you received a valid response (sorry for the formatting, the code tag isn't playing nicely at the moment)
if (response!=nil) {if([response isKindOfClass:[NSHTTPURLResponse class]]) {
// you have a valid response }}
I am developing an app using data from google reader's API and using GData for login.
I want to be able to mark a post inside a table cell as read / unread, but am finding the fact that this is all mainly undocumented hard to work out a solution, any ideas / links?
Here is the code for the mark read button:
//Get the token
NSString *tokenString = [NSString stringWithFormat:#"https://www.google.com/reader/api/0/token"];
NSURL *tokenURL = [NSURL URLWithString:tokenString];
NSMutableURLRequest *tokenRequest = [NSMutableURLRequest requestWithURL:tokenURL];
NSString *tokenStringResult;
NSArray *listItems;
NSError *tokenError = nil;
NSURLResponse *tokenResponse = nil;
NSData *tokenData = [NSURLConnection sendSynchronousRequest:tokenRequest
returningResponse:&tokenResponse
error:&tokenError];
if (tokenData)
{
tokenStringResult = [[NSString alloc] initWithData:tokenData encoding:NSUTF8StringEncoding];
listItems = [tokenStringResult componentsSeparatedByString:#"/"];
}
else
{
NSLog(#"tokenError = %#", tokenError);
}
// Mark it as read
NSString *readerURLString = [NSString stringWithFormat:#"http://www.google.com/reader/api/0/edit-tag?a=user/-/state/com.google/read&async=true&s=feed/%#&i=%#&T=%#", siteLink, postID, [listItems lastObject]];
NSURL *readerURL = [NSURL URLWithString:readerURLString];
NSMutableURLRequest *readerRequest = [NSMutableURLRequest requestWithURL:readerURL];
[mAuth authorizeRequest:readerRequest];
NSError *error = nil;
NSURLResponse *response = nil;
NSData *data = [NSURLConnection sendSynchronousRequest:readerRequest
returningResponse:&response
error:&error];
if (data)
{
NSHTTPURLResponse * httpResponse = (NSHTTPURLResponse *) response;
assert( [httpResponse isKindOfClass:[NSHTTPURLResponse class]] );
NSLog(#"response.allHeaderFields = %#", [httpResponse allHeaderFields]);
NSLog(#"response.statusCode = %i", [httpResponse statusCode]);
}
the log from this is:
response.statusCode = {
"Cache-Control" = "private, max-age=0";
"Content-Length" = 1334;
"Content-Type" = "text/html; charset=UTF-8";
Date = "Fri, 21 Jan 2011 03:49:07 GMT";
Expires = "Fri, 21 Jan 2011 03:49:07 GMT";
Server = GSE;
"X-Content-Type-Options" = nosniff;
"X-Frame-Options" = SAMEORIGIN;
"X-Reader-Google-Version" = "527-000";
"X-Reader-User" = 01940378872835844713;
"X-Xss-Protection" = "1; mode=block";
}
response.statusCode = 400
So through alot of trial and error I've got it working.

If you are familiar with php I wrote a tutorial on using the google readi api recently.
http://mobile.tutsplus.com/tutorials/mobile-web-apps/building-a-mobile-web-application-with-the-google-reader-api/
One thing I notice is that in this string
http://www.google.com/reader/api/0/edit-tag/a=user/-/state/com.google/read&async=true&s=feed/%#&i=%#
Your not including the "edit" token the url should look like this. and you need the ? after edit-tag.
http://www.google.com/reader/api/0/edit-tag?a=user/-/state/com.google/read&async=true&s=feed/%#&i=%#&T=%#
You can get the "edit" token from this link once you have the user logged in, https://www.google.com/reader/api/0/token
Sorry can't help with objective-c stuff.
