  • ping to web server from iphone

    - by Sreelal
    Hi , I am developing an aplication which needs to download some data from webserver.So i need to first ping to the web server to check whether the service is available after checking the internet connectivity .I used the following code to check server availability ` BOOL success = NO; const char *host_name = [@"http://192.168.1.7:8080/TestWeb/webresources/" cStringUsingEncoding:NSASCIIStringEncoding]; SCNetworkReachabilityRef reachability = SCNetworkReachabilityCreateWithName(NULL, host_name); SCNetworkReachabilityFlags flags; success = SCNetworkReachabilityGetFlags(reachability, &flags); BOOL isAvailable = success && (flags & kSCNetworkFlagsReachable) && !(flags & kSCNetworkFlagsConnectionRequired); return isAvailable; ` where my server is uploaded locally.But this code always return an invalid result,but it works correctly if i gave some exixting sites like google.com.Please let me know whats i am doing wrong..

  • iPhone colorize UILabel substrings

    - by Janosch R
    Hey, I’m parsing a twitter rss feed, and I just need to show tweets, so I don't need MGTwitterEngine. I have already set it up so I can see the complete tweet, the only thing I want it to colorize hashtags and urls. So I would need to slice up the string in different substrings, colorize the hashtags and urls and glue it together in various UILabels Is there an easier way to accomplish this? In short I need some parts of a string colored differently than others.

I followed the PDF viewing tutorial in which a webview was used but it only provides basic scrolling and zoom facilities. I have seen some apps in which bookmarks and page flipping is possible. Kindly suggest me something so that I can integrate more features.

  • iPhone: contentInset isn't animating

    - by Cuzog
    In my app, I have a table view. When the user clicks a button, a UIView overlays part of that table view. It's essentially a partial modal. That table view is intentionally still scrollable while that modal is active. To allow the user to scroll to the bottom of the table view, I change the contentInset and scrollIndicatorInsets values to adjust for the smaller area above the modal. When the modal is taken away, I reset those inset values. The problem is that when the user has scrolled to the bottom of the newly adjusted inset and then dismisses the modal, the table view jumps abruptly to a new scroll position because the inset is changed instantly. I would like to animate it so there is a transition, but the beginAnimation/commitAnimations methods aren't affecting it for some reason. Any ideas as to why the values aren't getting animated? Any help is greatly appreciated! The relevant code from the table view controller is here: - (void)viewDidLoad { [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(modalOpened) name:@"ModalStartedOpening" object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(modalDismissed) name:@"ModalStartedClosing" object:nil]; [super viewDidLoad]; } - (void)modalOpened { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.5]; [UIView setAnimationDelegate:self]; self.tableView.contentInset = UIEdgeInsetsMake(0, 0, 201, 0); self.tableView.scrollIndicatorInsets = UIEdgeInsetsMake(0, 0, 201, 0); [UIView commitAnimations]; } - (void)modalDismissed { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.5]; [UIView setAnimationDelegate:self]; self.tableView.contentInset = UIEdgeInsetsMake(0, 0, 0, 0); self.tableView.scrollIndicatorInsets = UIEdgeInsetsMake(0, 0, 0, 0); [UIView commitAnimations]; }

  • iPhone dev - viewDidUnload subviews

    - by Mk12
    I'm having a hard time undestand a couple of the methods in UIViewController, but first I'll say what I think they are meant for (ignoring interface builder because I'm not using it): -init: initialize non view-related stuff that won't need to be released in low memory situations (i.e. not objects or objects that can't be recreated easily). -loadView: create the view set the [self view] property. -viewDidLoad: Create all the other view elements -viewDidUnload: Release objects created in -viewDidLoad. didReceiveMemoryWarning: Low-memory situation, release unnecessary things such as cached data, if this view doesn't have a superview then the [super didReceiveMemoryWarning] will go on to release (unload) the view and call -viewDidUnload. -dealloc: release everything -viewWillAppear:, -viewDidAppear:, -viewWillDisappear:, -viewDidDisappear: self-explanatory, not necessary unless you want to respond (do something) to those events. I'm not sure about a couple of things. First, the Apple docs say that when -viewDidUnload is called, the view has already been released and set to nil. Will -loadView get called again to recreate the view later on? There's a few things I created in -viewDidLoad that I didn't make a ivar/property for because there is no need and it will be retained by the view (because they are subviews of it). So when the view is released, it will release those too, right? When the view is released, will it release all its subviews? Because all the objects I created in -viewDidLoad are subviews of [self view]. So if they already get released why release them again in -viewDidUnload? I can understand data that is necessary when the view is visible being loaded and unloaded in these methods, but like I asked, why release the subviews if they already get released? EDIT: After reading other questions, I think I might have got it (my 2nd question). In the situation where I just use a local variable, alloc it, make it a subview and release, it will have a retain count of 1 (from adding it as a subview), so when the view is released it is too. Now for the view elements with ivars pointing to them, I wasn't using properties because no outside class would need to access them. But now I think that that's wrong, because in this situation: // MyViewController.h @interface MyViewController : UIViewController { UILabel *myLabel; } // MyViewController.m . . . - (void)viewDidLoad { myLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 40, 10)]; [myLabel setText:@"Foobar"]; [[self view] addSubview:myLabel]; } - (void)viewDidUnload [ // equivalent of [self setMyLabel:nil]; without properties [myLabel release]; myLabel = nil; } In that situation, the label will be sent the -release message after it was deallocated because the ivar didn't retain it (because it wasn't a property). But with a property the retain count would be two: the view retaining it and the property. So then in -viewDidUnload it will get deallocated. So its best to just always use properties for these things, am I right? Or not? EDIT: I read somewhere that -viewDidLoad and -viewDidUnload are only for use with Interface Builder, that if you are doing everything programmatically you shouldn't use them. Is that right? Why?

  • Prompting user for multiple selections in an iphone app

    - by Matt Delves
    I'm currently looking for a way to provide the user with being able to select multiple items from a collection of values. I know this is done in the mail app whereby you can go into the edit mode of a folder and select multiple items by clicking on the circle on the left hand side. What I'm unsure about is how this is achievable. Is anyone familiar with how to reproduce such functionality? Thanks, Matt Delves

  • iPhone -- initialization partly by NSKeyedUnarchiver and partly by other means

    - by William Jockusch
    I have an object myObj, which is an instance of a class MyClass. Some of its instance variables always have their initial values passed in by the calling code. Other instance variables will be initialized in one of two ways. For an instanceArray of type NSMutableArray, the possibilities are either instanceArray = [[NSMutableArray alloc]init]; or instanceArray = [someKeyedUnarchiver decodeObjectForKey: kInstanceArrayKey]; The calling code should determine which of the above will be used. Any particular design pattern I should prefer?

  • Toggle iPhone tethering by code

    - by Canada Dev
    I live in Canada, so am fortunate that I can tether. One issue is that to toggle tethering, you need to drill down four screens in Settings, which is just a big hassle. A Google search returned nothing, so I was wondering if anyone here knew the code to turn on/off tethering? I know there's a toggle for SBSettings, but I do not have a jailbroken phone, I just want to create an app I build onto my phone and have an icon for quickly toggling it. Thanks

  • iPhone: UITableView Becomes Invisible after Changing the Data it Displays

    - by Alexander Shemshurenko
    Hi I have application with a TabBar that controls several views. In one view, I control connections to different servers. Each server provides a different set of items. I display these items in UITableView on another view. The problem is that the tableview displays OK the first time but if I go back to view number one and change the server, thereby changing the list of items that should be displayed in tableview, the tableview becomes invisible for some reason. If I tap on the screen in the place where it should be, it becomes visible again. I create table view like this UITableView * aTableView = [[UITableView alloc] initWithFrame:CGRectMake(X,Y,Width,Height) style:UITableViewStyleGrouped]; [[self view] addSubview:aTableView]; aTableView.dataSource = self; Ive tried to call reloadData and setNeedsDisplay in viewWillAppear of the UIViewController that hosts this tableview but without success. Any advice? Thanks

  • iphone download several files

    - by Floo
    hi all !  In my app i need to download several plist.  to download a plist i use the NSURLconnection  in my code i use an UIAlertView with a UIActivityIndicator then when the download is finished i add a button to the alert to dismiss it.  To download the plist i use somewhere in my code an NSURL set to the adresse where the plist is, next i set a NSURLRequest with the url cache policy and a timeout interval.  Then i set my NSMutableData to the NSURL connection with a NSURLRequest.  In the delegate didReceiveData: i append data to my mutable data object, in the didFailWithError: i handle error. And finaly in the connectionDidFinishLoading  i serialize my data to a plist so i can write to file my plist, and release my alertview.  My problem is : how can i do if i have sevetal file to download because the connectionDidFinishLoading is called each time my NSURLConnection is finished but i want to release my UiAlert when everything is finished. But when the first plist is downloaded my code in the connectionDidFinishLoading will fire.  here is my code :  in the view did load :  // set the UiAlert in the view did load  NSURL *theUrl = [NSURL URLWithString:@"http://adress.com/plist/myPlist.plist"]; NSURLRequest *theRequest = [NSURLRequest requestWithURL:theUrl cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0]; self.plistConnection = [[ NSURLConnection alloc] initwithRequest:theRequest delegate:self startImmediatly:YES]; //plistConnection is a NSURLConnection - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {  [incomingPListData appendData:data]; } -(void)connection:(NSURLConnection *)connectionDidFailWithError:(NSError *)error { // handle error here  } -(void)connectionDidFinisloading:(NSURLConnection *) connection {  NSPropertyListFormat format; NSString *serialErrorString;  NSData *plist = [NSPropertyListSerialisation propertyListFromData:incomingPlistData mutabilityOption:NSPropertyListImmutable format:&format errorDescription:&serialErrorString]; if (serialErrorString) {//error} else { // create path and write plist to path} // change message and title of the alert so if i want todownload an another file  where do i put the request the connection and how can i tell the didFinishLoading to fire code when all my file are downloaded.  thanks to all

  • Google Toolbox For Mac with Core Data on iPhone results in error

    - by JaanusSiim
    I have set up my project for using Google Toolbox for Mac as described on official wiki. And everything is working as expected. For core data usage I have created a 'database' class that uses for final application SQLite storage (this is done based on Xcode template code). For unit tests I have created separate init method for 'database' to use in memory storage (storage url is [NSURL URLWithString:@"memory://store"] and type NSInMemoryStoreType). Without adding my model file (*.xcdatamodel) to unit tests target, test fail in expected place with message: executeFetchRequest:error: A fetch request must have an entity. If I add model file to the test target, then test is executed as expected (core data part looks OK), but after tests execution I get: RunIPhoneUnitTest.sh: line 123: 9487 Segmentation fault "$TARGET_BUILD_DIR/$EXECUTABLE_PATH" -RegisterForSystemEvents Command /bin/sh failed with exit code 139 This problem does not looks directly related to core data, but only happens if model file is added to target. Any pointers on resolving this issue would be appreciated!

I guess I need someone to point me in the right direction. Thanks!
