• Application with two UITabBarControls

  - by kovpas

  Hello, I want to create an app, whith the following structure: UITabBarController ..UINavigationController ....UITabBarController So, in other words, I want to load first UITabbarController as my main ViewController, that appears on application start, in its' first tab there's a UINavigationController with a table, which shows another UITabBarController by pressing on a table cell. I started Tab Based application, set first tab to UINavigationController, and its ViewController to my TableViewController. I also created second UITabBarController in Interface Builder. Created a separate class for this controller. Everything works fine at start - my first UITabBarController is shown perfectly, but when I'm trying to push my second UITabBarController, using my UINavigationController, it looks like nothing is loaded from a .xib file - there are just an empty TabBar and NavigationBar pushed. Seems, that something is wrong with an architecture, but I can't figure out the problem. Thanks in advance and I'm sorry for my poor English. Please let me know if something is not clear, I'll try to rephrase it :).

• Difference between performSelectorInBackground and NSOperation Subclass

  - by AmitSri

  I have created one testing app for running deep counter loop. I run the loop fuction in background thread using performSelectorInBackground and also NSOperation subclass separately. I am also using performSelectorOnMainThread to notify main thread within backgroundthread method and [NSNotificationCenter defaultCenter] postNotificationName within NSOperation subclass to notify main thread for updating UI. Initially both the implementation giving me same result and i am able to update UI without having any problem. The only difference i found is the Thread count between two implementations. The performSelectorInBackground implementation created one thread and got terminated after loop finished and my app thread count again goes to 1. The NSOperation subclass implementation created two new threads and keep exists in the application and i can see 3 threads after loop got finished in main() function. So, my question is why two threads created by NSOperation and why it didn't get terminated just like the first background thread implementation? I am little bit confuse and unable to decide which implementation is best in-terms of performance and memory management. Thanks

• Setting a UITableViewCell accessory type on some cells, but not all

  I have 8 cells that are being built in my UITableViewController. I would like to know how I can show a disclosure indicator on the 4th and 8th cells. Right now I am building it in - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath though I am fully aware it is going to add a disclosure indicator to every cell cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;

• iPhone UnitTesting UITextField value and otest error 133

  - by Justin Galzic

  Are UITextFields not meant to be part of the LogicTests and instead part of the ApplicationTest target? I have a factory class that is responsible for creating and returning an (iPhone) UITextField and I'm trying to unit test it. It is part of my Logic Test target and when I try to build and run the tests, I get a build error about: /Developer/Tools/RunPlatformUnitTests.include:451:0 Test rig '/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.1.2.sdk/ 'Developer/usr/bin/otest' exited abnormally with code 133 (it may have crashed). In the build window, this points to the following line in: "RunPlatformUnitTests.include" RPUTIFail ${LINENO} "Test rig '${TEST_RIG}' exited abnormally with code ${TEST_RIG_RESULT} (it may have crashed)." My unit test looks like this: #import <SenTestingKit/SenTestingKit.h> #import <UIKit/UIKit.h> // Test-subject headers. #import "TextFieldFactory.h" @interface TextFieldFactoryTests : SenTestCase { } @end @implementation TextFieldFactoryTests #pragma mark Test Setup/teardown - (void) setUp { NSLog(@"%@ setUp", self.name); } - (void) tearDown { NSLog(@"%@ tearDown", self.name); } #pragma mark Tests - (void) testUITextField_NotASecureField { NSLog(@"%@ start", self.name); UITextField *textField = [TextFieldFactory createTextField:YES]; NSLog(@"%@ end", self.name); } The class I'm trying to test: // Header file #import <Foundation/Foundation.h> #import <UIKit/UIKit.h> @interface TextFieldFactory : NSObject { } +(UITextField *)createTextField:(BOOL)isSecureField; @end // Implementation file #import "TextFieldFactory.h" @implementation TextFieldFactory +(UITextField *)createTextField:(BOOL)isSecureField { // x,y,z,w are constants declared else where UITextField *textField = [[[UITextField alloc] initWithFrame:CGRectMake(x, y, z, w)] autorelease]; // some initialization code return textField; } @end

• UITableViewCellSeparatorStyleNone does not hide blue separator line when selecting in UITableView

  - by clozach

  Before describing the problem, let me first point out that this is a distinct issue from this question. The Problem This screenshot was taken with a break set at tableView:didSelectRowAtIndexPath:, and as you can see in the simulator (far right of the image), there's a single-pixel blue line at the bottom of the selected cell. This is not the design asked for by the client, nor is it how this app used to behave: there should be no separator, even on selection. How I Got Here I'd initially designed this table view using custom UITableViewCell classes with corresponding nib (.xib) files and had no trouble with selections: the separator was hidden as desired. Predictably, scrolling was sluggish due to all the overhead from the view hierarchy, so I reworked the custom cells to use Loren Brichter's fast scrolling solution. Now scrolling is much faster, but I can't get rid of the separator for the life of me. What I've tried At the time of the screenshot above... the table view has "Separator [None]" in IB. the UIViewController that contains the table view has this line in viewDid Load: self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone; As you can see in the screenshot, I inserted some unused lines to prove that separatorStyle is set as desired. Other testing confirms that tableView and self.tableView are equivalent pointers at that same breakpoint. I've also tried setting tableView.separatorColor to black and to clear, all with the same result: the cells look right until a selection is made.

• MKMapView doesn't want to call didAddAnnotationViews method

  I am writing a little map kit app but it doesn't want to call the delegate method didaddannotationviews: (void)mapView:(MKMapView *)mv didAddAnnotationViews:(NSArray *)views { //Get the first MKAnnotationView from the views returned MKAnnotationView *annotationView = [views objectAtIndex:0]; //Get the annotation from the first annotation view and save it in a variable which can hold any object as long as it implements mkannotation id <MKAnnotation> mp = [annotationView annotation]; //Create a region MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance([mp coordinate], 250, 250); //As the mapview to animate i.e. display the region [mv setRegion:region animated:YES]; } @interface WhereAmIAppDelegate : NSObject { UIWindow *window; CLLocationManager *locationManager; IBOutlet MKMapView *mapView; IBOutlet UIActivityIndicatorView *activityIndicator; IBOutlet UITextField *locationTitleField; }

• UINavigationController does not set view properties correctly when pushed

  - by Sheehan Alam

  I have a UITabBarControllerDelegate that pushes a new view controller when a certain tab is pressed: - (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController { MyView* myView = [[[MyView alloc] initWithNibName:@"MyView" bundle:nil]autorelease]; if([self.tabBarController.selectedViewController.title isEqualToString:@"Friends"]){ NSLog(@"Clicked Friends"); myView.reloadFriends = TRUE; [self.navigationController myView animated:YES]; } } However, if I change my code to set the tabbar's selected view controller to myView everything works, but I don't get my navigation bar: if([self.tabBarController.selectedViewController.title isEqualToString:@"Friends"]){ NSLog(@"Clicked Friends"); myView.reloadFriends = TRUE; self.tabBarController.selectedViewController = myView; } How can I set the reloadFriends property in MyView and have the navigation bar at the top?

  I've read plenty of requests about a full-on custom UINavigationBar background, but what I want is to overlay a logo on the default UINavigationBar instead of text. Preferably, I'd like to apply it to a subclass of UINavigationBar called CustomNavigationBar. Thanks in advance.

• Custom UITableViewCell won't redraw on setNeedsDisplay

  - by Andrew Portner

  I created a custom UITableViewCell class with a UIButton, a UIImage, and two UILabels. The button and the image are overlayed on top of each other, and only one is displayed at a time. The expected behavior is you touch on the button, the button disappears, and it displays the image. The UITableViewCells are set to be reused. Here's my code: Constructor: - (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier { if (self = [super initWithStyle:style reuseIdentifier:reuseIdentifier]) { unheartButton = [[UIButton buttonWithType:UIButtonTypeCustom] retain]; unheartButton.backgroundColor = [UIColor clearColor]; unheartButton.frame = CGRectMake(10, 13, 20, 18); [unheartButton addTarget:self action:@selector(onButtonClick:) forControlEvents:UIControlEventTouchUpInside]; [unheartButton setBackgroundImage:[UIImage imageNamed:@"redheart.png"] forState:UIControlStateNormal]; imageView = [[UIImageView alloc] init]; imageView.frame = CGRectMake(12, 13, 16, 16); NSMutableArray *array = [[NSMutableArray alloc] init]; for (int ndx = 1; ndx < 13; ndx++) { [array addObject:[UIImage imageNamed:[NSString stringWithFormat:@"icon-loading-%d (dragged).tiff", ndx]]]; } imageView.animationImages = array; imageView.animationDuration = 1; imageView.hidden = YES; [array release]; [self.contentView addSubview:imageView]; [self.contentView addSubview:unheartButton]; return self; } } Button click: - (IBAction) onButtonClick: (id) sender { unheartButton.hidden = YES; imageView.hidden = NO; [imageView startAnimating]; [self setNeedsDisplay]; [self.contentView setNeedsDisplay]; [self.unheartButton setNeedsDisplay]; [self.imageView setNeedsDisplay]; } I'm calling setNeedsDisplay on everything, but nothing seems to happen. If I scroll off the screen and back up, the button is hidden and now the loading icon is shown, but this only happens after a scroll. I'm not sure what I need to do to get the cell to repaint.

• Why won't my UISearchDisplayController fire the didSelectRowAtIndexPath moethod?

  - by John Wells

  I am having an odd problem when searching a UITableView using a UISearchDisplayController. The UITableViewController is a subclass of another UITableViewController with a working didSelectRowAtIndexPath method.

• How to detect touches on MPMoviePlayerController window and still having the standard playback cont

  - by gkedmi

  Hello I have the MPMoviePlayerController set up to play a movie.I want to detect a touch on the movie for bringing up few buttons.I used the code : // The movie's window is the one that is active UIWindow* moviePlayerWindow = [[UIApplication sharedApplication] keyWindow]; // Now we create an invisible control with the same size as the window UIControl* overlay = [[[UIControl alloc] initWithFrame:moviePlayerWindow.frame]autorelease]; // We want to get notified whenever the overlay control is touched [overlay addTarget:self action:@selector(movieWindowTouched:) forControlEvents:UIControlEventTouchDown]; // Add the overlay to the window's subviews [moviePlayerWindow addSubview:overlay]; but then the play back controllers doesn't appear , I guess because the player window doesn't get the touch.how can I keep the player controllers and still detects touches? thanks

• How can I detect touch events on a UIImageView inside a deep hierarchy of UIViews?

  - by jester

  I am developing a simple game on iPhone and I started with a View based application, and through the UIViewController I am loading a custom UIView that contains some more UIViews and some UIImageViews. I want to detect touch events on some of the UIImageViews, but I wasn't able so far. I've created a second project for testing purposes and figured that UIImageViews handle touch events when the hierarchy is like : UIViewController - UIView - UIImageView, but when it's like : UIViewController - UIView - UIView - UIImageView they are not detected. Notes: - userInteractionEnabled is YES in all cases - all UIViews and UIImageViews I mention above are custom subclasses. Can you think of any reason why, when a custom UIImageView gets deeper in the view hierarchy can't receive touch events?

• UIButton: how to center an image and a text using imageEdgeInsets and titleEdgeInsets?

  - by R31n4ld0_

  Hello, guys. If I put only an image in a button and set the imageEdgeInsets more close to the top, the image stays centered and all works as expected: [button setImage:image forState:UIControlStateNormal]; [button setImageEdgeInsets:UIEdgeInsetsMake(-15.0, 0.0, 0.0, 0.0)]; If I put only a text in a button and set titleEdgeInsets more close to the bottom, the text stays centered and all works as expected: [distractionButton setTitle:title forState:UIControlStateNormal]; [distractionButton setTitleEdgeInsets:UIEdgeInsetsMake(0.0, 0.0, -30, 0.0)]; But, if i put the 4 lines together one interfere with other and both lost the center alignment. All my images has 30 pixels widht, and if i put 30 in the left parameter of UIEdgeInsetMake for setTitleEdgeInsets, the text is centered again. The problem is that the image never gets centered because appears that it is dependent of the button.titleLabel size. I already tried many calculations with button size, image size, titleLabel size and never get both perfectly centered. Someone already have the same problem? Thanks in advance.

• Saving custom attributes in NSAttributedString

  - by regulus6633

  I need to add a custom attribute to the selected text in an NSTextView. So I can do that by getting the attributed string for the selection, adding a custom attribute to it, and then replacing the selection with my new attributed string. So now I get the text view's attributed string as NSData and write it to a file. Later when I open that file and restore it to the text view my custom attributes are gone! After working out the entire scheme for my custom attribute I find that custom attributes are not saved for you. Look at the IMPORTANT note here: http://developer.apple.com/mac/library/DOCUMENTATION/Cocoa/Conceptual/AttributedStrings/Tasks/RTFAndAttrStrings.html So I have no idea how to save and restore my documents with this custom attribute. Any help?

• How optimize code with introspection + heavy alloc on iPhone

  - by mamcx

  I have a problem. I try to display a UITable that could have 2000-20000 records (typicall numbers.) I have a SQLite database similar to the Apple contacts application. I do all the tricks I know to get a smoth scroll, but I have a problem. I load the data in 50 recods blocks. Then, when the user scroll, request next 50 until finish the list. However, load that 50 records cause a notable "pause" in loading and scrolling. Everything else works fine. I cache the data, have opaque cells, draw it by code, etc... I swap the code loading the same data in dicts and have a performance boost but wonder if I could keep my object oriented aproach and improve the actual code. This is the code I think have the performance problem: -(NSArray *) loadAndFill: (NSString *)sql theClass: (Class)cls { [self openDb]; NSMutableArray *list = [NSMutableArray array]; NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; DbObject *ds; Class myClass = NSClassFromString([DbObject getTableName:cls]); FMResultSet *rs = [self load:sql]; while ([rs next]) { ds = [[myClass alloc] init]; NSDictionary *props = [ds properties]; NSString *fieldType = nil; id fieldValue; for (NSString *fieldName in [props allKeys]) { fieldType = [props objectForKey: fieldName]; fieldValue = [self ValueForField:rs Name:fieldName Type:fieldType]; [ds setValue:fieldValue forKey:fieldName]; } [list addObject :ds]; [ds release]; } [rs close]; [pool drain]; return list; } And I think the main culprit is: -(id) ValueForField: (FMResultSet *)rs Name:(NSString *)fieldName Type:(NSString *)fieldType { id fieldValue = nil; if ([fieldType isEqualToString:@"i"] || // int [fieldType isEqualToString:@"I"] || // unsigned int [fieldType isEqualToString:@"s"] || // short [fieldType isEqualToString:@"S"] || // unsigned short [fieldType isEqualToString:@"f"] || // float [fieldType isEqualToString:@"d"] ) // double { fieldValue = [NSNumber numberWithInt: [rs longForColumn:fieldName]]; } else if ([fieldType isEqualToString:@"B"]) // bool or _Bool { fieldValue = [NSNumber numberWithBool: [rs boolForColumn:fieldName]]; } else if ([fieldType isEqualToString:@"l"] || // long [fieldType isEqualToString:@"L"] || // usigned long [fieldType isEqualToString:@"q"] || // long long [fieldType isEqualToString:@"Q"] ) // unsigned long long { fieldValue = [NSNumber numberWithLong: [rs longForColumn:fieldName]]; } else if ([fieldType isEqualToString:@"c"] || // char [fieldType isEqualToString:@"C"] ) // unsigned char { fieldValue = [rs stringForColumn:fieldName]; //Is really a boolean? if ([fieldValue isEqualToString:@"0"] || [fieldValue isEqualToString:@"1"]) { fieldValue = [NSNumber numberWithInt: [fieldValue intValue]]; } } else if ([fieldType hasPrefix:@"@"] ) // Object { NSString *className = [fieldType substringWithRange:NSMakeRange(2, [fieldType length]-3)]; if ([className isEqualToString:@"NSString"]) { fieldValue = [rs stringForColumn:fieldName]; } else if ([className isEqualToString:@"NSDate"]) { NSDateFormatter* dateFormatter = [[NSDateFormatter alloc] init]; [dateFormatter setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss"]; NSString *theDate = [rs stringForColumn:fieldName]; if (theDate) { fieldValue = [dateFormatter dateFromString: theDate]; } else { fieldValue = nil; } [dateFormatter release]; } else if ([className isEqualToString:@"NSInteger"]) { fieldValue = [NSNumber numberWithInt: [rs intForColumn :fieldName]]; } else if ([className isEqualToString:@"NSDecimalNumber"]) { fieldValue = [rs stringForColumn :fieldName]; if (fieldValue) { fieldValue = [NSDecimalNumber decimalNumberWithString:[rs stringForColumn :fieldName]]; } } else if ([className isEqualToString:@"NSNumber"]) { fieldValue = [NSNumber numberWithDouble: [rs doubleForColumn:fieldName]]; } else { //Is a relationship one-to-one? if (![fieldType hasPrefix:@"NS"]) { id rel = class_createInstance(NSClassFromString(className), sizeof(unsigned)); Class theClass = [rel class]; if ([rel isKindOfClass:[DbObject class]]) { fieldValue = [rel init]; //Load the record...

• Convert charset name to NSStringEncoding

  - by d11wtq

  Given a charset string, such as "utf-8", "iso-8859-1", "us-ascii" etc, is there any built-in way to get the appropriate NSStringEncoding in Cocoa? Right now I'm looking at just building a NSDictionary containing a canonicalized version of the name mapped to the NSStringEncoding, then having a lookup mechanism that canonicalizes the input in the same way. But is there really no way to get NSUTF8StringEncoding given the string "UTF-8", etc?

• unrecognized selector sent to instance on deviceOrientationDidChange

  - by clopez

  Right now my app should only supports Portrait. On Summary/Supported Device Orientations I have only selected Portrait so I'm hoping that my app will not rotate. I was testing the app on a device and suddenly I'm getting the following error randomly: [UIButtonContent deviceOrientationDidChange:]: unrecognized selector sent to instance It happens when I rotate the device SOMETIMES, is not consistent, and is not always over UIBUttonContent. I supposed that if I only select Portrait, deviceOrientationDidChange should not be called or should be ignored. Other times my app crashes with an EXC_BAD_ACCESS (code=1, address=something) but it happens when I rotate the device so I'm guessing that both errors are related. I don't know what to do with this, it's hard to debug because I don't have feedback, the All Exceptions Breakpoint is not being called, so I don't know where and exactly why this is happening. Any idea on how to debug this is welcome.

• Memory leak issue with UIImagePickerController

  - by Mustafa

  I'm getting memory leak with UIImagePickerController class. Here's how I'm using it: UIImagePickerController *picker = [[UIImagePickerController alloc] init]; picker.delegate = self; picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; [self presentModalViewController:picker animated:YES]; [picker release]; To remove the picker i call [picker dismissModalViewControllerAnimated:YES]; in didFinishPickingImage and imagePickerControllerDidCancel. -- Instruments show around 160bytes leaking as a result of this instruction: +[UIImagePickerController _loadPhotoLibraryIfNecessary] Apparently this issue has and is disturbing many people, and solution to avoid this problem is to build a singleton class dedicated for picking images from library or capturing using device's build in camera. Anyone want to add something?

• How to make a UITextField move up when keyboard is present

  - by philfreo

  EDIT: Over 1k views with 3 upvotes? If this question is helpful, vote it up :) With the iPhone SDK: I have a UIView with UITextFields that brings up a keyboard. I need it to be able to: Allow scrolling of the contents of the UIScrollView to see the other text fields once the keyboard is brought up Automatically "jump" (by scrolling up) or shortening I know that I need a UIScrollView. I've tried changing the class of my UIView to a UIScrollView but I'm still unable to scroll the textboxes up or down. Do I need both a UIView and a UIScrollView? Does one go inside the other? [EDIT: I now know that you want a UIView inside of a UIScrollView, and the trick is to programatically set the content size of the UIScrollView to the frame size of the UIView.] Then what needs to be implemented in order to automatically scroll to the active text field? Ideally as much of the setup of the components as possible will be done in Interface Builder. I'd like to only write code for what needs it. Note: the UIView (or UIScrollView) that I'm working with is brought up by a tabbar (UITabBar), which needs to function as normal. Edit: I am adding the scroll bar just for when the keyboard comes up. Even though it's not needed, I feel like it provides a better interface because then the user can scroll and change textboxes, for example. I've got it working where I change the frame size of the UIScrollView when the keyboard goes up and down. I'm simply using: -(void)textFieldDidBeginEditing:(UITextField *)textField { //Keyboard becomes visible scrollView.frame = CGRectMake(scrollView.frame.origin.x, scrollView.frame.origin.y, scrollView.frame.size.width, scrollView.frame.size.height - 215 + 50); //resize } -(void)textFieldDidEndEditing:(UITextField *)textField { //keyboard will hide scrollView.frame = CGRectMake(scrollView.frame.origin.x, scrollView.frame.origin.y, scrollView.frame.size.width, scrollView.frame.size.height + 215 - 50); //resize } However this doesn't automatically "move up" or center the lower text fields in the visible area, which is what I would really like.
