I tried this way but it's not working.
This is the url to convert to base 64
NSString *strUrlB64 = [NSString stringWithFormat:#"https://play.google.com/store/apps/details?id=com.ShiftSharerfree_new&feature=search_result#?t=W251bGwsMSwyLDEsImNvbS5TGlmdFNoYXJlcmZyZWVfbmV3Il0"];
NSData *dataUrl = [NSData dataFromBase64String:strUrlB64];
Then tried to send this to another url.
NSString *urlStr = [NSString stringWithFormat:#"http://server39.pnht.com/360ad/apps/ads/%#/android/136/ord0.910950258132325?json=1&package_url=%#",self.mStrPid, dataUrl];
It is giving me output: NSString *urlStr = [NSString stringWithFormat:#"http://server39.pbgs.com/360ads/apps/ad/%#/android/1360/ord0.910950252132325?json=1&package_url=%#",self.mStrPid, url];
It is not base 64. please guide how to get base 64 out of it.
I am using base 64 to encode and decode some text,
can u tell me if it works with URLs,
- (NSString *)base64Encode:(NSString *)plainText
{
NSData *plainTextData = [plainText dataUsingEncoding:NSUTF8StringEncoding];
NSString *base64String = [plainTextData base64EncodedString];
return base64String;
}
- (NSString *)base64Decode:(NSString *)base64String
{
NSData *plainTextData = [NSData dataFromBase64String:base64String];
NSString *plainText = [[NSString alloc] initWithData:plainTextData encoding:NSUTF8StringEncoding];
return plainText;
}

i am Parsing HTML Tag into iOS using Hpple. i am able to parse the data where the HTML Tag is
<div id="NewsPageSubTitle">
<p><**span** hi how are you>
Using ios code:
NSString *tutorialsXpathQueryString = #"//div[#id='NewsPageArticle']/p/span ";
NSArray *tutorialsNodes = [tutorialsParser searchWithXPathQuery:tutorialsXpathQueryString];
but in few case i don't have span, imean the string in html is accessed by tag "p" directly like:
<div id="NewsPageSubTitle">
<p>< hi how are you>
Here I am using ios code as:
NSString *tutorialsXpathQueryString = #"//div[#id='NewsPageArticle']/p ";
NSArray *tutorialsNodes = [tutorialsParser searchWithXPathQuery:tutorialsXpathQueryString];
but here i am getting a blank data in response.
can any one let me know how to solve the problem?
Since sometimes the para tag has span and sometimes it does not, I would suggest trying to handle that by looping over the children
NSString *filePath = [[NSBundle mainBundle] pathForResource:#"index" ofType:#"html"];
NSData * data = [NSData dataWithContentsOfFile:filePath];
TFHpple * tutorialsParser = [[TFHpple alloc] initWithHTMLData:data];
NSString *tutorialsXpathQueryString = #"//div[#id='NewsPageSubTitle']";
NSArray *tutorialsNodes = [tutorialsParser searchWithXPathQuery:tutorialsXpathQueryString];
for (TFHppleElement * element in tutorialsNodes) {
NSLog(#"%#", element);
NSLog(#"%#", [element tagName]);
NSLog(#"%#", [element attributes]);
NSLog(#"%#", [element children]);
for (TFHppleElement *childElement in [element children]) {
NSLog(#"%#", childElement);
}
}
Check with this: https://github.com/mwaterfall/MWFeedParser
This will provide the HTML Parser for iphone sdk.

NSString *filePath = [[NSBundle mainBundle] pathForResource:#"image" ofType:#"html" inDirectory:#"New Folder 2"];
NSData * data = [NSData dataWithContentsOfFile:filePath];
NSFileHandle *readHandle = [NSFileHandle fileHandleForReadingAtPath:filePath];
NSString *htmlString = [[NSString alloc] initWithData:[readHandle readDataToEndOfFile] encoding:NSUTF8StringEncoding];
TFHpple * Parser = [[TFHpple alloc] initWithHTMLData:data];
NSString *query = #"//p";
NSArray *nodes = [Parser searchWithXPathQuery:query];
for (TFHppleElement *item in nodes)
{
NSLog(#"Title : %#", item.content);
NSLog(#"URL : %#", [item.attributes valueForKey:#"href"]);
}
I have the following php file:
<?php
$username="root";
$database="testdb";
mysql_connect(localhost,$username);
$user=$_GET["user"];
$password=$_GET["password"];
$query="SELECT documento FROM person WHERE user='".$user." and password ='".$password."'";
$result=mysql_query($query) or die (mysql_error("error "));
$num=mysql_numrows($result);
mysql_close();
$rows=array();
while($r=mysql_fetch_assoc($result)){
$rows[]=$r;
}
echo json_encode($rows);
?>
to retrieve the information achieved by the following functions but the example did not have the php input conditions and parameters was select * from person here the functions
based in http://www.youtube.com/watch?feature=endscreen&v=IQcLngIDf9k&NR=1
-(void) getData:(NSData *) data{
NSError *error;
json = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
}
-(void) start {
NSURL *url = [NSURL URLWithString:kGETUrl];
NSData *data = [NSData dataWithContentsOfURL:url];
[self getData:data];
}
now as the sql statement has input parameters is not as code and tried something like this A Simple PHP/MySQL Web Service for iOS but I can not accommodate what I need.
Pass the parameters in the string. Here is an example
-(void) start {
NSString *user = [[NSString alloc] initWithString:#"exampleuser"];
NSString *password = [[NSString alloc] initWithString:#"examplepassword"];
NSString *urlstr = [[NSString alloc] initWithFormat:#"http://myserver.com/myphpfile.php?user=%#?password=%#", user, password];
NSURL *url = [NSURL URLWithString:urlstr];
NSData *data = [NSData dataWithContentsOfURL:url];
[self getData:data];
}
As it is password and user it normally is better to use POST instead of GET because then it is not part of the URL which is visible. With POST you can hide it if you have a https line. But I think this is not your main concern right now. The above should work.
I made some change in Hollfeder's code and it worked perfectly :)
-(void) start {
NSString *user = [[NSString alloc] initWithString:#"exampleuser"];
NSString *password = [[NSString alloc] initWithString:#"examplepassword"];
NSString *urlstr = [[NSString alloc] initWithFormat:#"http://myserver.com/myphpfile.php?user=%#&password=%#", user, password];
NSString *urlstr_encoded = [urlstr stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding];
NSURL *url = [NSURL URLWithString:urlstr_encoded];
NSData *data = [NSData dataWithContentsOfURL:url];
[self getData:data];
}
I am having an issue while trying to convert NSString to NSData and vice versa.
I am trying to store encrypted string to my database. For that I am using AES algorithm. Now what I am doing is I get encrypted NSData and I am converting this to NSString using following:
// Not woking
NSString *strTemp = [[NSString alloc] initWithData:encData encoding:NSUTF8StringEncoding];
// Working
NSString *strTemp = [[NSString alloc] initWithData:encData encoding:NSASCIIStringEncoding];
Why NSData is not converting while using NSUTF8StringEncoding. Same way when I try to convert the string got by NSASCIIStringEncoding using:
// Not working
[strTemp dataUsingEncoding:NSASCIIStringEncoding];
// Working
[strTemp dataUsingEncoding:NSUTF8StringEncoding];
Why NSASCIIStringEncoding is not working while converting the NSString to NSData?
NSString to NSData:
NSString* str= #"teststring";
NSData* data=[str dataUsingEncoding:NSUTF8StringEncoding];
NSData to NSString:
NSString* newStr = [[NSString alloc] initWithData:theData
encoding:NSUTF8StringEncoding];
Please mind that NSASCIIStringEncoding and NSUTF8StringEncoding need to match the characters in the string.
I want to convert one NSString to NSData. on Using encoding am getting different value in NSData by displaying it using its description property.
I have
NSString *str=#"80369F4";
NSData *data = [str dataUsingEncoding:NSUTF8StringEncoding];
on printing [data description]; am getting some different values...
how to extract the same string from the NSData.. pl help me out on this problem.
Create a new NSString:
NSString *newString = [[[NSString alloc] initWithData: data encoding: NSUTF8StringEncoding] autorelease];
You can use NSString's initWithData:encoding: method:
NSString *str=#"80369F4";
NSData *data = [str dataUsingEncoding:NSUTF8StringEncoding];
NSString *sameString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
This is the string I need to post http://www.mysite.com/save?details={"name"}
Iam trying the following code;
NSString *post =[NSString stringWithFormat:#"details={\"name\"}"];
NSString *hostStr = #"http://www.mysite.com/save?";
hostStr = [hostStr stringByAppendingString:post];
NSData *dataURL = [NSData dataWithContentsOfURL: [ NSURL URLWithString: hostStr]];
NSString *serverOutput = [[NSString alloc] initWithData:dataURL encoding: NSASCIIStringEncoding];
but the serverOutput always = null, unless i do just {name}. but i need the qutoes in there :(
You should convert everythign to valid HTTP symbols.
e.g.:
hostStr = [hostStr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
...my guess is that your webserver is refusing your invalid URL.
wrong ..
NSString *post =[NSString stringWithFormat:#"details={\"name\"}"];
Correct:
NSString *post =[NSString stringWithString:#"details={\"name\"}"];
