  • Remove year component from NSDateFormatter style

    - by JK
    I would like to present a date in the kCFDateFormatterFullStyle, but without the year. Is there any way to remove the year component from this style? My app requires localization so practically I cannot programmatically set the format string for all locales. I have come accross a solution which removes the "y" characters from the format string returned by the built in styles. Unfortunately, this is not acceptable as the year components are not represented by "y" in some other languages like Japanese. Any suggestions to get the kCFDateFormatterFullStyle without the year would be great! Thanks.

  • Creating a Pop animation similar to the presentation of UIAlertView

    - by JK
    I would like to present a view in the same manner as that of UIAlertView - a pop/spring. Unfortunately subclassing UIAlertView is not an option for the view I need to present. I have written some code, but I can't seem to get it as realistic as I would like. I would appreciate any suggestions for greater realism or a link if anything similar has been done (I could not find anything on Google). Thank you. - (id)initWithFrame:(CGRect)frame { if ((self = [super initWithFrame:frame])) { self.backgroundColor = [UIColor whiteColor]; v = [[UIView alloc] initWithFrame:CGRectMake(140, 140, 60, 60)]; v.backgroundColor = [UIColor blueColor]; [self addSubview:v]; [self animate]; } return self; } - (void)animate { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationCurve:UIViewAnimationCurveLinear]; [UIView setAnimationDuration:0.2]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(popStep1Complete)]; v.frame = CGRectMake(90, 90, 140, 140); [UIView commitAnimations]; } - (void)popStep1Complete { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationCurve:UIViewAnimationCurveLinear]; [UIView setAnimationDuration:0.15]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(popStep2Complete)]; v.frame = CGRectMake(110, 110, 100, 100); [UIView commitAnimations]; } - (void)popStep2Complete { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationCurve:UIViewAnimationCurveLinear]; [UIView setAnimationDuration:0.15]; v.frame = CGRectMake(100, 100, 120, 120); [UIView commitAnimations]; }

  • What's the best way to call an IBAction from within code?

    - by Rob
    Say for instance I have an IBAction that is hooked up to a button in interface builder. - (IBAction)functionToBeCalled:(id)sender { // do something here } Within my code, say for instance in another method, what is the best way to call that IBAction? If I try to call it like this, I receive an error: [self functionToBeCalled:]; But, if I try to call it like this (cheating a bit, I think), it works fine: [self functionToBeCalled:0]; What is the proper way to call it though?

  • TabBar / "More View Controller" - Possible to have icons in colors other than black?

    - by Malakim
    Hi, Is it possible to have the icons in a TabBar and / or the "More navigation controller" be in colors other than grey and black? I tried changing the color of the icon I set for the view controller using UITabBarItem's - (id)initWithTitle:(NSString *)title image:(UIImage *)image tag:(NSInteger)tag method. My client thinks the interface is too dark and want's to brighten it up with some colorful icons... Thanks!

  • Problem while looping on a NSDictionary

    - by Tom
    Hi! The end of my loop causes a EXC_BAD_ACCESS. Here's my dictionary (AppDelegate.data): 1 = ( 3, "Test 1", False, "" ); 2 = ( 4, "Test 2", False, "" ); And here is my loop: for (id theKey in AppDelegate.data) { if (theKey = nil) { NSLog(@"HOLY COW"); } else { NSLog(@"Key: %@ ?", theKey); } } It never says holy cow, and it says the right key but at the end it crashes... Do you have any idea why? It should only loop on 1 and two and then exit the loop... I know that there's always a "nil" object at the end that's why I did a condition with it but it doesn't look like it works at all.. Thanks!

  • Resizing a UIView - expanding the top

    - by Mongus Pong
    I have a UIView inside of a UIScrollView that I want to resize. I can increase the height easily by : CGRect frame = self.drawinView.frame; frame.size.height += 100; self.drawinView.frame = frame; self.drawinScrollView.contentSize = CGSizeMake(frame.size.width, frame.size.height); And all is good. The above code will create a new area of the view at the bottom of the view that I can fill out. Now when I resize the view, I only want to be repainting the new portion of the view that has just been created. I dont want to have to repaint the whole view. However! I have run into difficulty when I need to expand the top of the view. Doing : CGRect frame = self.drawinView.frame; frame.origin.y -= 100; self.drawinView.frame = frame; self.drawinScrollView.contentSize = CGSizeMake(500, 600); does not work. How can I do this without having to repaint the entire view?

  • Downloading large files with AFNetworking

    - by goodfella
    I'm trying to implement downloading of a large file and show to user current progress, but block in: -[AFURLConnectionOperation setDownloadProgressBlock:] returns incorrect bytesRead and totalBytesRead values (they are smaller than they should be). For example: If I have a 90MB file and when it downloads completely, latest block invocation in setDownloadProgressBlock: gives me totalBytesRead value about 30MB. On other side, if file is 2MB large, latest block invocation gives correct totalBytesRead 2MB value. AFNetworking is updated to the latest version from github. If AFNetworking can't do it correctly, what solution can I use? Edit: I've determined that even if file is not downloaded completely (and this happens every time with relatively big file) AFNetworking calls success block in: -[AFHTTPRequestOperation setCompletionBlockWithSuccess:failure] I asked a similar question here about this situation, but didn't get any answers. I can check in code downloaded and real file sizes, but AFNetworking has no API for continuation of partial download.

  • Loading UINavigationController from another nib automatically by UITabBarController

    - by porneL
    I think I've found the cause: Document Info window in IB has a warning: "'Selected Navigation Controller (Second)' has nib name property set to 'SecondView.nib', but this view controller is not intended to have its view set in this manner." Bummer. I've built nib in Interface Builder that has UITabBarController at top level and switches between UINavigationControllers. It works fine when everything is in a single nib file, but I'd like to use separate nib files for UINavigationControllers. Starting with Apple's TabBar template, if I just change class of SecondView to UINavigationController, it all breaks: and all I get is this: Is it possible to have separate file for UINavigationController without programmatically setting everything? I would like TabBarController to handle loading and unloading of nibs.

  • Rotating and Moving a UIImageView (CocoaTouch)

    - by yar
    This code works to rotate: CGAffineTransform transform = CGAffineTransformMakeRotation(radians(lastAngle++)); anImage.transform = transform; and this code works to move my UIImageView CGRect frame = [anImage frame]; frame.origin.x+=1; frame.origin.y+=1; [anImage setFrame:frame]; but when I combine them, the image stretches out increasingly on each run through. Perhaps the frame should not be modified like this?

  • How to wait until location is completely found? (Core Location)

    - by sudo rm -rf
    Hello. I have a problem within my app. I'm trying to find the user's location to the best preciseness in order to determine their zip-code. Currently I have a button that, when pressed, starts a method named locateMe. -(IBAction)locateMe; { self.locationManager = [[CLLocationManager alloc] init]; locationManager.delegate = self; locationManager.desiredAccuracy = kCLLocationAccuracyBest; [locationManager startUpdatingLocation]; Then I've implemented didUpdateToLocation: -(void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation; { NSLog(@"Found location! %f,%f",newLocation.coordinate.latitude,newLocation.coordinate.longitude); } I had previously done much more complicated stuff in didUpdateToLocation but as I tested some things I realized that the first location it found was not precise in the least. So, I put the NSLog call in there and it gave me an output similar to below... Found location! 39.594093,-98.614834 Found location! 39.601372,-98.592171 Found location! 39.601372,-98.592171 Found location! 39.611444,-98.538196 Found location! 39.611444,-98.538196 As you can see, it first gives me a value which is not correct, which was causing problems within my app because it wasn't giving the correct location. So, here's my question. Is there any way I can wait for the location manager to finish finding the most precise location? Thanks in advance! EDIT: I'm wanting something like this: if (newLocation.horizontalAccuracy <= locationManager.desiredAccuracy) { } But it never gets called!

  • Issue scrolling table view with content inset

    - by Rog
    Hi all, I am experiencing a weird scrolling issue and I was hoping someone could give me a hand in trying to identify why this is happening. I have included the part of my code that I think is relevant to the question but am happy to update this post with whatever else is needed. I have implemented a pull to refresh view in the tableview's content inset area. The refresh fires an Async NSURLConnection that pulls data from a webserver, parses the relevant information and refreshes the table as required. This is where the refresh process kicks off: - (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate{ if (scrollView.contentOffset.y <= - 65.0f && !self.reloading) { self.reloading = YES; [self reloadTableViewDataSource]; [refreshHeaderView setState:EGOOPullRefreshLoading]; [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.2]; self.tableView.contentInset = UIEdgeInsetsMake(60.0f, 0.0f, 0.0f, 0.0f); [UIView commitAnimations]; } } Problem is if I start to scroll whilst the content inset is "visible" (i.e. during reload) I get this weird behaviour where my table sections do not scroll all the way to the top - see screenshot for a clear visual of what I am trying to describe here. I have included a couple of screenshots below that clearly identify what is happening at the moment. Has anyone experienced this before? Any ideas on what I should be looking at to try and fix it? Many thanks in advance, Rog And this is the result if I start scrolling the table. The orange bit at the top of the image is the actual navigation bar, where I would expect the table section (date 1 December 2010) to be.

  • How to rotate a UIImageView?

    - by jkally
    It's quite frustrating not to be able to do such a simple task: I have an "app" with a single viewcontroller, and in it a single UIImageView, that's initialized to a specific image at potrtait mode. Now when the iPhone gets roteated to landscape mode and the shouldAutorotateToInterfaceOrientation event fires, at which I return YES, my resulting UIImageView looks totally screwed up: either the image is stretched so to fill landscape mode frame (which looks ridiculuous of course) or the top and bottom of the image are cropped. How can I have my UIImageview and the contained image handle the device rotation gracefully, and display normal looking image at landscape mode as well?

  • How can I dynamically hide a button from a view?

    - by jpm
    I would like to dynamically hide a button in one of my views, depending on a certain condition. I tried adding some code to the view controller's -viewWillAppear method, to make the button hidden before displaying the actual view, but I still don't know how to do that. I have a reference to the button through an IBOutlet, but I'm not sure how to move forward from here. For reference, this is a UIBarButtonItem instance.

  • Core Data Predicates with Subclassed NSManagedObjects

    - by coneybeare
    I have an AUDIO class. This audio has a SOUND_A subclass and a SOUND_B subclass. This is all done correctly and is working fine. I have another model, lets call it PLAYLIST_JOIN, and this can contain (in the real world) SOUND_A's and SOUND_B's, so we give it a relationship of AUDIO and PLAYLIST. This all works in the app. The problem I am having now is querying the PLAYLIST_JOIN table with an NSPredicate. What I want to do is find an exact PLAYLIST_JOIN item by giving it 2 keys in the predicate sound_a._sound_a_id = %@ && playlist.playlist_id = %@ and sound_b.sound_b_id = %@ && playlist.playlist_id = %@ The main problem is that because the table does not store sound_a and sound_b, but stored audio, I cannot use this syntax. I do not have the option of reorganizing the sound_a and sound_b to use the same _id attribute name, so how do I do this? Can I pass a method to the predicate? something like this: [audio getID] = %@ && playlist_id = %@

  • How to get cell text based on indexPath?

    - by Sheehan Alam
    I have a UITabBarController with more than 5 UITabBarItems so the moreNavigationController is available. In my UITabBarController Delegate I do the following: - (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController { //do some stuff //... UITableView *moreView = (UITableView *)self.tabBarController.moreNavigationController.topViewController.view; moreView.delegate = self; } I want to implement a UITableViewDelegate so I can capture the row that was selected, set a custom view property and then push the view controller: - (void)tableView:(UITableView *)tblView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { //how can I get the text of the cell here? } I need to get the text of a cell when the user taps on a row. How can I accomplish this?

  • iPhone Camera and Image Chooser

    - by PF1
    Hi Everyone: I have found a lot of information on using UIImagePickerController to let the user choose the image they want from the Photos application's data. I am wondering how I can create this same effect on 3.0, as it doesn't seem as if a lot of the old code works anymore. In addition, I would like the user to be able to take a new picture from this same pop-up. Thanks for any help!

  • iPhone write to file (alternative directory)

    - by strider2k
    New to iPhone 3.2, Apple introduced File-Sharing support. Details can be found at https://developer.apple.com/iphone/library/releasenotes/General/WhatsNewIniPhoneOS/Articles/iPhoneOS3_2.html#//apple_ref/doc/uid/TP40009337-SW1 . Now, most examples floating around in the web demonstrates writing to the documents directory. What if I want to write files from my app but I don't want the user to be able to see it via iTunes? I'm looking at the Files and Networking section of the iPhone OS Programming Guide and I'm unsure what would be a good alternative to the documents directory for writing files to hide from the user and not be rejected by Apple's review team.
