I've put UIsegment Control in my IPhone application.To load the pages I've this function
- (void) segmentSelected:(id)segmentedCntl{
NSLog(#"Selected Segment Index = %d", [segmentedCntl selectedSegmentIndex]);
int index = [segmentedCntl selectedSegmentIndex];
ViewController *viewController = (ViewController *) controller;
NSString *xPath = [NSString stringWithFormat:#"item[%d]/a", (index + 1)];
NSArray *items = [element nodesForXPath:xPath error:nil];
if([items count] > 0){
CXMLElement *itemElement = (CXMLElement *) [items objectAtIndex:0];
NSString *url = [[itemElement attributeForName:#"href"] stringValue];
NSLog(#"url is &&&&&&&&&&&&&&&& %#", url);
if([url startsWith:#"#"]){
}else{
NSString *fullURL = [URLLoader getURL:url];
if(fullURL != nil){
if([fullURL contains:#"?"]){
fullURL = [fullURL stringByAppendingString:#"&iPhoneMode=app"];
}else{
fullURL = [fullURL stringByAppendingString:#"?iPhoneMode=app"];
}
[viewController showURL:fullURL cacheDuration:kPageCacheDuartion];
}
}
}
}
But the segmentControl is not clickable.Please help me to solve this problem
Namastey saikamesh
Please check proper u'r UISegmentControl property setting it will be working.

Hello I am parsing a RSS And Atom feeds, and my question is how can I check for < img > and < url > tags in < description >?
There must be some sort of check. Thanks.
Here is how I parse them:
- (NSArray *)parseFeed:(NSURL *)feedURL{
NSError *error;
NSData *data = [NSData dataWithContentsOfURL:feedURL];
GDataXMLDocument *xmlParse = [[GDataXMLDocument alloc] initWithData:data error:&error];
GDataXMLElement *rootElement = xmlParse.rootElement;
NSArray *array = [[NSArray alloc] init];
if ([rootElement.name compare:#"rss"] == NSOrderedSame) {
array = [self parseRSSFeed:rootElement];
return array;
} else if ([rootElement.name compare:#"feed"] == NSOrderedSame) {
array = [self parseAtomFeed:rootElement];
return array;
} else {
NSLog(#"Unsupported root element: %#", rootElement.name);
return nil;
}
}
-(NSArray *)parseRSSFeed:(GDataXMLElement *) rootElement
{
NSMutableArray *entries = [[NSMutableArray alloc] init];
NSArray *channels = [rootElement elementsForName:#"channel"];
for (GDataXMLElement *channel in channels) {
NSArray *items = [channel elementsForName:#"item"];
for (GDataXMLElement *item in items) {
FeedItem *itemF = [[FeedItem alloc] init];
itemF.title = [item valueForChild:#"title"];
itemF.description = [item valueForChild:#"description"];
NSLog(#"IMAGE - %#", [item valueForChild:#"img"]);
itemF.dateString = [item valueForChild:#"pubDate"];
itemF.link = [NSURL URLWithString:[item valueForChild:#"link"]];
itemF.dateString = [item valueForChild:#"updated"];
itemF.author = [item valueForChild:#"author"];
[entries addObject:itemF];
NSLog(#"RSS - %#", itemF.title);
}
}
NSArray *RSSArray = [entries copy];
return RSSArray;
}
-(NSArray *)parseAtomFeed:(GDataXMLElement *) rootElement
{
NSMutableArray *entries = [[NSMutableArray alloc] init];
NSArray *entry = [rootElement elementsForName:#"entry"];
for (GDataXMLElement *entryElement in entry) {
// NSArray *items = [channel elementsForName:#"item"];
//for (GDataXMLElement *item in items) {
FeedItem *itemF = [[FeedItem alloc] init];
itemF.title = [entryElement valueForChild:#"title"];
itemF.description = [entryElement valueForChild:#"summary"];
NSArray *links = [entryElement elementsForName:#"link"];
for (GDataXMLElement *link in links) {
itemF.link = [NSURL URLWithString:[[link attributeForName:#"href"] stringValue]];
}
itemF.dateString = [entryElement valueForChild:#"updated"];
NSArray *authors = [entryElement elementsForName:#"author"];
for (GDataXMLElement *authorElement in authors) {
itemF.author = [authorElement valueForChild:#"name"];
}
[entries addObject:itemF];
NSLog(#"Atom - %#", itemF.title);
}
NSArray *atomArray = [entries copy];
return atomArray;
}
I am parsing them using GDataXMLParser, and my own parser class.
Do it like this:
NSString *Str=[item valueForChild:#"description"];
NSArray *tmp=[Str componentsSeparatedByString:#"<Img>"];
if([tmp count]>1){
NSString *urlstr=[[tmp objectatindex:1] stringByReplacingOccurrencesOfString:#" </Img>" withString:#""];
}
Now urlstr contains your image url.
Enjoy
I thought that
itemF.description = [item valueForChild:#"description"];
is NSString. So you can use componentsSeparatedByString with "your tag".
It will return array. In array at postion 1 you will get your img url.
This url has closing bracket "your closing tag".
Replace "your closing tag" with space. You will get image url.
Hope, this will help you.
I have develop one iphone application and now I want to Use this application as module in another project. How can I do this?
you can just drag n drop projectA into projectB (in Xcode), or choose "add files to" (do not check the option "copy files")
Copy the relevant classes and resources into the project you want to add the module to and then create some kind of controller interface (tabbar, navigation controller) to navigate between the two projects (in the project you copied into)

How can I parse a mailto request ?
'mailto:someone#example.com?cc=someone_else#example.com&subject=This%20is%20the%20subject&body=This%20is%20the%20body'
From this NSURL, I want to extract the recipient, the subject and the body. How should I do ?
Thanks
Here is some code that will parse any URL and return a dictionary with the parameters and the associated objects in a dictionary. It works for mailto URLs, too.
Please note: This code assumes you're using ARC!
#interface NSString (URLDecoding)
- (NSString *) URLDecodedString;
#end
#implementation NSString (URLDecoding)
- (NSString *) URLDecodedString {
NSString *result = (__bridge_transfer NSString *)CFURLCreateStringByReplacingPercentEscapesUsingEncoding(kCFAllocatorDefault, (__bridge CFStringRef)self, CFSTR(""), kCFStringEncodingUTF8);
return result;
}
#end
- (NSDictionary *) parameterDictionaryFromURL:(NSURL *)url {
NSMutableDictionary *parameterDictionary = [[NSMutableDictionary alloc] init];
if ([[url scheme] isEqualToString:#"mailto"]) {
NSString *mailtoParameterString = [[url absoluteString] substringFromIndex:[#"mailto:" length]];
NSUInteger questionMarkLocation = [mailtoParameterString rangeOfString:#"?"].location;
[parameterDictionary setObject:[mailtoParameterString substringToIndex:questionMarkLocation] forKey:#"recipient"];
if (questionMarkLocation != NSNotFound) {
NSString *parameterString = [mailtoParameterString substringFromIndex:questionMarkLocation + 1];
NSArray *keyValuePairs = [parameterString componentsSeparatedByString:#"&"];
for (NSString *queryString in keyValuePairs) {
NSArray *keyValuePair = [queryString componentsSeparatedByString:#"="];
if (keyValuePair.count == 2)
[parameterDictionary setObject:[[keyValuePair objectAtIndex:1] URLDecodedString] forKey:[[keyValuePair objectAtIndex:0] URLDecodedString]];
}
}
}
else {
NSString *parameterString = [url parameterString];
NSArray *keyValuePairs = [parameterString componentsSeparatedByString:#"&"];
for (NSString *queryString in keyValuePairs) {
NSArray *keyValuePair = [queryString componentsSeparatedByString:#"="];
if (keyValuePair.count == 2)
[parameterDictionary setObject:[[keyValuePair objectAtIndex:1] URLDecodedString] forKey:[[keyValuePair objectAtIndex:0] URLDecodedString]];
}
}
return [parameterDictionary copy];
}
And here is how you use it:
NSURL *mailtoURL = [NSURL URLWithString:#"mailto:foo#example.com?cc=bar#example.com&subject=Greetings%20from%20Cupertino!&body=Wish%20you%20were%20here!"];
NSDictionary *parameterDictionary = [self parameterDictionaryFromURL:mailtoURL];
NSString *recipient = [parameterDictionary objectForKey:#"recipient"];
NSString *subject = [parameterDictionary objectForKey:#"subject"];
NSString *body = [parameterDictionary objectForKey:#"body"];
EDIT:
I updated the code to work with any URL and recipients are now in the dictionary for mailto URLs.
I would pull the email from that like this:
NSString * mailToString = #"'mailto:someone#example.com?cc=someone_else#example.com&subject=This%20is%20the%20subject&body=This%20is%20the%20body'";
NSArray *tempArray = [mailToString componentsSeparatedByString:#"?"];
//get email address from array
NSString * emailString = [[tempArray objectAtIndex:0]description];
//clean up string
emailString = [emailString stringByReplacingOccurrencesOfString:#"'mailto:" withString:#""];
//and here is your email string
NSLog(#"%#",emailString);
Since iOS 7 this is easily doable with NSURLComponents. You can create that object with:
if let components = NSURLComponents(URL: url, resolvingAgainstBaseURL:false) { ...
Then you can get the recipient accessing the path property of NSURLComponents; and the parameters with the queryItems property. For instance, if we wanted to get the subject, something like this would do our job
let queryItems = components.queryItems as? [NSURLQueryItem]
let subject = queryItems?.filter({$0.name == "subject"}).first?.value
NSURL category for just mailto: This method also has a fix for a crash bug in Fabian's answer above when mailto: url doesn't contain a ?. It also doesn't require the URLDecodedString category method.

in app i want to show subject name in tableviewcontroller when application launch & when we clicked on tableviewcell it leads on another table view which shows sub_subject list.
how to achieve this
for that.
+ (NSString *)dataFilePath:(BOOL)forSave {
return [[NSBundle mainBundle] pathForResource:#"SubjectData" ofType:#"xml"];
}
+ (RootSubject *)loadParty {
NSString *filePath = [self dataFilePath:FALSE];
NSData *xmlData = [[NSMutableData alloc] initWithContentsOfFile:filePath];
NSError *error;
GDataXMLDocument *doc = [[GDataXMLDocument alloc] initWithData:xmlData
options:0 error:&error];
/* if (doc == nil) { return nil; }
NSLog(#"%#", doc.rootElement);
[doc release];
[xmlData release];
return nil;*/
RootSubject *rootSubject = [[[RootSubject alloc] init] autorelease];
NSArray *partyMembers = [doc nodesForXPath:#"//Root/Subject" error:nil];
//NSArray *patry = [doc nodesForXPath:#"//Root/Subject/SunjectID" error:nil];
for (GDataXMLElement *partyMember in partyMembers) {
// Let's fill these in!
NSString *subjectId, *subjectName, *sub_SubjectId, *sub_SubjectName;
// senderName
NSArray *subjectIds = [partyMember elementsForName:#"SubjectID"];
if (subjectIds.count > 0) {
GDataXMLElement *firstName = (GDataXMLElement *) [subjectIds objectAtIndex:0];
subjectId = firstName.stringValue;
} else continue;
// senderEmail
NSArray *subjectNames = [partyMember elementsForName:#"SubjectName"];
if (subjectNames.count > 0) {
GDataXMLElement *firstLevel = (GDataXMLElement *) [subjectNames objectAtIndex:0];
subjectName = firstLevel.stringValue;
} else continue;
/* //senderPhone
NSArray *sub_SubjectIds = [partyMember elementsForName:#"Sub_SubjectID"];
if (sub_SubjectIds.count > 0) {
GDataXMLElement *firstName = (GDataXMLElement *) [sub_SubjectIds objectAtIndex:0];
sub_SubjectId = firstName.stringValue;
} else continue;
//senderLocation
NSArray *sub_SubjectNames = [partyMember elementsForName:#"Sub_SubjectName"];
if (sub_SubjectNames.count > 0) {
GDataXMLElement *firstName = (GDataXMLElement *) [sub_SubjectNames objectAtIndex:0];
sub_SubjectName = firstName.stringValue;
} else continue;*/
//Subject *subject = [[[Subject alloc]initWithSubjectId:subjectId subjectName:subjectName sub_SubjectId:sub_SubjectId sub_SubjectName:sub_SubjectName]autorelease];
Subject *subject = [[[Subject alloc]initWithSubjectId:subjectId subjectName:subjectName sub_SubjectId:nil sub_SubjectName:nil]autorelease];
//Subject *subject = [[[Subject alloc]initWithSubjectId:subjectId subjectName:nil sub_SubjectId:sub_SubjectId sub_SubjectName:sub_SubjectName]autorelease];
//[rootGroup.groups addObject:group];
[rootSubject.subjects addObject:subject];
}
[doc release];
[xmlData release];
return rootSubject;
}
through this we get subject name and show it perfectly in tableviewcontroller but when i clicked on particular subject which provides subsubject in another view controller

I need to know how you can find out when all processes (loaded) from a - (void) are done, if it's possible.
Why? I'm loading in data for a UITableView, and I need to know when a Loading... view can be replaced with the UITableView, and when I can start creating the cells.
This is my code:
- (void) reloadData {
NSAutoreleasePool *releasePool = [[NSAutoreleasePool alloc] init];
NSLog(#"Reloading data.");
NSURL *urlPosts = [NSURL URLWithString:[NSString stringWithFormat:#"%#", URL]];
NSError *lookupError = nil;
NSString *data = [[NSString alloc] initWithContentsOfURL:urlPosts encoding:NSUTF8StringEncoding error:&lookupError];
postsData = [data componentsSeparatedByString:#"~"];
[data release], data = nil;
urlPosts = nil;
self.numberOfPosts = [[postsData objectAtIndex:0] intValue];
self.postsArrayID = [[postsData objectAtIndex:1] componentsSeparatedByString:#"#"];
self.postsArrayDate = [[postsData objectAtIndex:2] componentsSeparatedByString:#"#"];
self.postsArrayTitle = [[postsData objectAtIndex:3] componentsSeparatedByString:#"#"];
self.postsArrayComments = [[postsData objectAtIndex:4] componentsSeparatedByString:#"#"];
self.postsArrayImgSrc = [[postsData objectAtIndex:5] componentsSeparatedByString:#"#"];
NSMutableArray *writeToPlist = [NSMutableArray array];
NSMutableArray *writeToNoImagePlist = [NSMutableArray array];
NSMutableArray *imagesStored = [NSMutableArray arrayWithContentsOfFile:[rootPath stringByAppendingPathComponent:#"imagesStored.plist"]];
int loop = 0;
for (NSString *postID in postsArrayID) {
if ([imagesStored containsObject:[NSString stringWithFormat:#"%#.png", postID]]){
NSLog(#"Allready stored, jump to next. ID: %#", postID);
continue;
}
NSLog(#"%#.png", postID);
NSData *imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:[postsArrayImgSrc objectAtIndex:loop]]];
// If image contains anything, set cellImage to image. If image is empty, try one more time or use noImage.png, set in IB
if (imageData == nil){
NSLog(#"imageData is empty before trying .jpeg");
// If image == nil, try to replace .jpg with .jpeg, and if that worked, set cellImage to that image. If that is also nil, use noImage.png, set in IB.
imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:[[postsArrayImgSrc objectAtIndex:loop] stringByReplacingOccurrencesOfString:#".jpg" withString:#".jpeg"]]];
}
if (imageData != nil){
NSLog(#"imageData is NOT empty when creating file");
[fileManager createFileAtPath:[rootPath stringByAppendingPathComponent:[NSString stringWithFormat:#"images/%#.png", postID]] contents:imageData attributes:nil];
[writeToPlist addObject:[NSString stringWithFormat:#"%#.png", postID]];
} else {
[writeToNoImagePlist addObject:[NSString stringWithFormat:#"%#", postID]];
}
imageData = nil;
loop++;
NSLog(#"imagePlist: %#\nnoImagePlist: %#", writeToPlist, writeToNoImagePlist);
}
NSMutableArray *writeToAllPlist = [NSMutableArray arrayWithArray:writeToPlist];
[writeToPlist addObjectsFromArray:[NSArray arrayWithContentsOfFile:nowPlist]];
[writeToAllPlist addObjectsFromArray:[NSArray arrayWithContentsOfFile:[rootPath stringByAppendingPathComponent:#"imagesStored.plist"]]];
[writeToNoImagePlist addObjectsFromArray:[NSArray arrayWithContentsOfFile:[rootPath stringByAppendingPathComponent:#"noImage.plist"]]];
[writeToPlist writeToFile:nowPlist atomically:YES];
[writeToAllPlist writeToFile:[rootPath stringByAppendingPathComponent:#"imagesStored.plist"] atomically:YES];
[writeToNoImagePlist writeToFile:[rootPath stringByAppendingPathComponent:#"noImage.plist"] atomically:YES];
[releasePool release];
}
It is as simple as returning a bool at the bottom of the selector being run in the background, and reaload the UITableView.
Thanks to #iWasRobbed:
I have never done this, but just speculating: have you tried returning a BOOL at the very end so that the reloadData function will return TRUE when it gets to that point? I am assuming (possibly incorrectly) that the device serially handles tasks one-at-a-time, so give it a shot.
