  • UILabel with custom font displays *wrong* custom font

    - by winsmith
    I'm using this method to embed custom fonts in my iPhone app. The embedding works: When I run the following code, the fonts are listed. (Currently, I'm embedding all family members of Myriad Pro in OTF format) for( NSString *familyName in [UIFont familyNames] ){ for( NSString *fntName in [UIFont fontNamesForFamilyName:familyName] ){ NSLog(@"%@", fntName); }} When I try to set the font of a label to MyriadPro or MyriadPro-Bold, this works just as expected. However, when I set the font to MyriadPro-BoldCond, the label is still set in MyriadPro-Bold instead of the condensed version. (The font names are correct, I checked.) My Code: [recommendationLabel setFont:[UIFont fontWithName:@"MyriadPro-BoldCond" size:140]]; recommendationLabel.adjustsFontSizeToFitWidth = YES; What's the deal?

  • multiple regionDidChangeAnimated calls - what gives?

    - by mvexel
    I have a MKMapView inside a UITableView as a custom cell (don't ask ;) - don't know if it matters really), for which I register a regionDidChangeAnimated delegate method. This method gets called three times when the UITableView is loaded - once with the actual region and then two more times with a region that is way off. In the simulator, I consistently get a region with center (+37.43997405, -97.03125000). On the device, it seems to depend on the location reported by the location manager, which initializes the map view. Why am I getting three regionDidChangeAnimated calls? And why are the center coordinates for the last two of them off? This is the code I use to get the center coordinates: - (void)mapView:(MKMapView *)mapView regionDidChangeAnimated:(BOOL)animated { CLLocation *l = [[CLLocation alloc] initWithLatitude:self.mapView.centerCoordinate.latitude longitude:self.mapView.centerCoordinate.longitude]; (....)

  • Getting MAX_INT from NSDateComponents

    - by MattyW
    I'm trying to write my first iPhone app, and I'm using a date picker object for the user to enter their date of birth. Part of my app requires the year in int format. I've added the code as below. What's odd is that 'month' gets the right value. But day and year seem to be stuck at MAX_INT (2147483647). Can anyone tell me what I'm doing wrong? -(IBAction)dateOfBirthChanged:(id)sender { NSCalendar* calender = [NSCalendar currentCalendar]; NSDateComponents* dateComponents = [calender components:NSMonthCalendarUnit fromDate:[datepicker date]]; NSInteger day = [dateComponents day]; NSInteger month = [dateComponents month]; NSInteger year = [dateComponents year]; label.text = [NSString stringWithFormat:@"Your year of birth is %d", year]; }

  • NSString potential leak

    - by VansFannel
    Hello. When I build and analyze my project on XCode, I obtain a 'warning' on the following line: NSString *contactEmail = (NSString *)ABMultiValueCopyValueAtIndex(emailInfo, 0); The message is: Potential leak on object allocated on line ... and stored into contactEmail. Is there any error on that line? UPDATE I get the same 'warning' with this line of code: ABMultiValueRef emailInfo = ABRecordCopyValue(person, kABPersonEmailProperty); But here, I can't do this: [emailInfo release]; I'm developing for iPhone.

  • Need new method for linking to native mapping from mobile web app

    - by Carter
    My mobile web apps use a map button which automatically starts the mapping features of Android and iPhone by simply linking to http://maps.google.com/maps?q=New+York. iOs 6 comes out, the links stop working, because Apple wants us to use "maps.APPLE.com". Turns out ANYTHING you send to "maps.apple.com" gets forwarded to "maps.google.com". So now I have to specially detect iOs 6 and swap out links just so Apple can forward everything back to Google anyway. Is there a clean way to open the device/native mapping app from a mobile web app that works on Android, iOs 6, and iOs pre-6, since iOs 6 nerfed it? Recently updated documentation on Apple dev site... http://developer.apple.com/library/ios/#featuredarticles/iPhoneURLScheme_Reference/Articles/MapLinks.html#//apple_ref/doc/uid/TP40007894-SW1 Both these links go to the same place http://maps.google.com/maps?q=New+York http://maps.apple.com/maps?q=New+York

  • Send data to server with GET

    - by coderjoe
    I have made a site where all my highscores from my game are shown. I send the scores from my iphone game to my site using a script made with php. The script works, because if I enter the link produced by my app in my browser the score is added. However I want to send the scores from my app. The script is using the GET method to get name, scores etcetera. This is what i have now: NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:urlString]]; NSError * e; NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:&e]; But it's not sending data to my server. The urlString is correct, because if I enter the link produced by my app in my browser the score is added. How can i solve this problem, Thanks in advance

  • Forcing Reload of View when returning from FlipSideView of Utility Application

    - by Chris McCall
    I've got a Utility Application for iPhone 3.1.3. I have my main view loading fine. I flip over to the flipside view of the utility app and change some settings. How can I call the code I've currently got in viewDidLoad in the main view to refresh it, as settings have changed? Do I create a public method and call it from the viewDidUnload method of the flipside view? Do I call viewDidLoad directly? What's the best way to do this?

  • How to show/hide UIImageView when I want.

    - by Madness64
    I'm having a little problem with an iPhone app I'm currently developing. When the user touch a button, it calls an IBAction named refreshQuestion, which is supposed to show an image hover the screen to ask the user to wait a moment, then it has to call another function, and finally it has to hide the image. The problem is that the image won't appear. As well as the network activity indicator. Any help? Here is the code : - (IBAction)refreshQuestion:(id)sender{ pleaseWait.hidden = NO; [UIApplication sharedApplication].networkActivityIndicatorVisible = YES; [self loadData]; pleaseWait.hidden = YES; [UIApplication sharedApplication].networkActivityIndicatorVisible = NO; }

  • EXC_BAD_ACCESS from AudioBuffer

    - by jfalexvijay
    I am trying to do the record using AudioUnit for iPhone app. Changes: (start) I have added the following code bufferList = (AudioBufferList *)malloc(sizeof(AudioBuffer)); bufferList-mNumberBuffers = 1; bufferList-mBuffers[0].mNumberChannels = 2; bufferList-mBuffers[0].mDataByteSize = 1024; bufferList-mBuffers[0].mData = calloc(256, sizeof(uint32_t)); Changes: (end) static OSStatus recordingCallback(void *inRefCon, AudioUnitRenderActionFlags *ioActionFlags, const AudioTimeStamp *inTimeStamp, UInt32 inBusNumber, UInt32 inNumberFrames, AudioBufferList *ioData) { OSStatus status; status = AudioUnitRender(appdelegate-audioUnit, ioActionFlags, inTimeStamp, inBusNumber, inNumberFrames, appdelegate-bufferList); if(status != 0) NSLog(@"AudioUnitRender status is %d", status); SInt16* samples = (SInt16*)(ioData-mBuffers[0].mData); ..... } fixed: (I am getting OSStatus -50 error code)- Because I didn't initialize the bufferList. I am EXC_BAD_ACCESS from AudioBuffer (ioData-mBuffers[0].mData). I am not sure with this error. Please help me to resolve it.

  • Quick way to get an NSDictionary from an XML NSData representation?

    - by dontWatchMyProfile
    I've loaded an XML file as NSData into memory and parse over the elements using NSXMLParser. Although it works, it's a very ugly and hard to maintain code since there are about 150 different elements to parse. I know there are nice third-party solutions, but I want to keep it with the iPhone SDK for purpose of practice and fun. So I thought: Why not convert that XML file into an NSDictionary? Having this, I could use fast enumeration to go over the elements. Or is it just the same amount of ugly code needed to parse and process an XML right away with NSXMLParser? Would I build up an NSDictionary for every found node in the XML and create a huge one, containing the whole structure and data? Or is there an even simpler way?

  • iPad --- managedObject problem when [self.tableViewSection reloadData]

    - by user345777
    Hi , I am creating a news aggregator application that fetches a xml feed every 4 minutes. After the xml is loaded, I clear everything by deleting all the objects in the database, then save the new objects back into the database. I then call [self.tableViewSection reloadData]; to reload the tableView. Thats when I get a problem. As soon as the code gets to a section where i access the new [[managedObject valueForKey:@"event_text"] description] content it fails with a : * Terminating app due to uncaught exception 'NSObjectInaccessibleException', reason: 'CoreData could not fulfill a fault for '0x4b3f6a0 '' Now from the flow I described on top, it seems odd to me that the tableView is populated properly the next time i launch the application, with the "new" data I fetched in the previous session. So its not that data thats corrupt , but seems to me something goes wrong when I refetch the managedObject after saving new data. Also keep in mind thats this app runs fine on the iPhone, its the iPad thats is giving me this problem.

  • IB z-order on simulator 6.0

    - by Stanley
    Consider the above's IB objects listing. Siblings further down the list should be on top of the siblings listed further up when rendered on the screen. Under Xcode 4.5.2, everything is ok if iphone simulator 5.1 is used. But for simulator 6.0 the map just covers everything. The same if using actual devices (phones) for testing. Hope that somebody knowledgeable could help. Please also add comments if you do not find such a problem on simulator 6.0. Because chances are the problem is related to how my project is setup. Update : Have setup a test project with the iOS 6 map view. There seems to be no problem with the z-order. So the problem should relate to my code.

  • Release variable and assigning it again

    - by David Gonrab
    What is the preferred and/or correct way to release an NSMutableString (or any other class for that matter) instance and assign a new instance to the same variable in Objective-C on the iPhone? Currently I'm using [current release]; current = [NSMutableString new]; but I understand that the following works, too. NSMutableString *new = [NSMutableString new]; [current release]; current = [new retain]; [new release]; The variable current is declared in the interface definition of my class and gets released in dealloc.

  • Constantly getting ...DeviceMonitor] Failed to start monitoring

    - by makar
    I find that after running or debugging my application a few times using eclipse, that I get the above output in my console (in red) and I get no feedback from Dalvik as to the connection status to my phone is going. My application will still debug etc. I just get nothing useful in my Console. Any ideas how to fix this? It appears intermittent. It starts doing it after a few minutes, continues to do it for quite a while and occasionally goes away again. This has happened on my last laptop and now on my new laptop with a completely fresh install etc.

  • [iOS] How to catch cancallation of UIScrollView or others?

    - by kyu
    Sometimes, interruptions such as phone call occur and disturb a regular behavior of an app in iPhone or iPad. For example, I created one UIScrollView instance and implemented UIScrollView delegate methods: scrollViewWillBeginDragging and scrollViewDidEndDragging(and scrollViewDidEndDecelerating). A scrollViewWillBeginDragging method deactivated all custom buttons in my app. Then scrollViewDidEndDragging and scrollViewDidEndDecelerating methods activated these custom buttons. That is, while the user scrolled, all custom buttons became deactivated for a while. The problem was that while the user started to drag and just held an UIScrollView instance, if I took a screenshot by pressing a home button and a power button, then any of scrollViewDidEndDragging and scrollViewDidEndDecelerating didn't get called. So the app became messed up. I implemented a UIApplicationWillResignActiveNotification method in my UIViewController, but it didn't get called after taking a screenshot. How can I catch any kind of interruption that disturbs a regular flow of events? Sometimes, touchesEnd and touchesCanceled didn't get called too due to an interruption. Thank you.

  • How can I dismiss the view appeared by touching Add item in UINavigationController ?

    - by srikanth rongali
    I have added add(+ symbol button) button to my navigation controller. When I click it a view appears from bottom. I added a navigation bar and two buttons to it. One save and one cancel button. And the view have one textEdit box. After editing I can save or cancel. If I touch cancel I need the view to disappear like it should go down again. I think all iPhone , iPodTouch users use it. Like when they touch Add item then a view appears from bottom and when they cancel it goes down again. How can I make in this way in my application.

  • Android/ iOS how to determine small changes in distance using sensors?

    - by Tom
    I have been doing a bit of research, but I cannot seem to find a way to determine small distances (centimeters and meters) using the sensors in Android or iOS devices. Bluetooth appears too inaccurate and require more than one device, GPS only works over larger variations in distance, and small variations in rotation seem to make using the accelerometer nearly impossible. Is there a method that I am unaware of that would allow me to do such a thing? I am familiar with Calculus, so using Integrals to determine distance based on changes in time and velocity/ acceleration is not a problem for me, I just do not know how to determine those things. Thank you.

  • UITableView - centering of Sections

    - by Raj
    Hi all, I am using a table view with its style set as "Grouped". I have only 2 sections to be displayed in the table view and the table view does not occupy full iPhone screen (It has some other views with it). So I would like to display those 2 sections centered in the table view rather than displaying the sections from the top of table view. One round about way is to set header and footer of the table view appropriately. But the disadvantage of this is, each sections will be equidistant (looks awkward!). Anybody with solutions to it? Thanks, Raj

  • Through Java, make a call to Javascript functions on networked device?

    - by stjowa
    I am doing device monitoring on a networked system. I need to know how to make Javascript calls on that device via its IP address to get certain status information (this device's status is only available through Javascript APIs, not SNMP, etc). I am working in Java. ADDED: The specific device is an Amino set-top-box. It has what it calls JMACX: JavaScript Media Access Control Extensions API specification. It allows you within an HTML document to use that API to get MUCH information about the device (cpu usage, channel info, remote-control options, etc.). I need to get this information within a Java program for specific monitoring purposes. Perhaps possible with HTTP requests? Any input would be greatly appreciated. Thanks, Steve
