I'm trying to convert this app i have from iPhone to iPad.. i've set the logic properly but i get bad excess error. Here is the code.
SortingILove *controller = nil;
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
{
controller = [[SortingILove alloc] initWithNibName:#"SortingILove-iPad" bundle:[NSBundle mainBundle]];
}
else
{
myTableView = [[UITableView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame] style:UITableViewStylePlain];
myTableView.delegate = self;
myTableView.dataSource = self;
itemsList = [[NSMutableArray alloc] init];
[itemsList addObject:#" attracted to Places"];
[itemsList addObject:#" in love with Shopping"];
[itemsList addObject:#" alive for Food"];
self.navigationItem.title = #"";
self.view = myTableView;
self.tableView.rowHeight=123;
self.tableView.autoresizesSubviews = YES;
self.tableView.scrollEnabled = YES;
self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
self.tableView.backgroundColor = [UIColor blackColor];
UIImage *backgroundImage = [UIImage imageNamed:#"Background.jpg"];
UIImageView *backgroundViews = [[[UIImageView alloc] initWithImage:backgroundImage] autorelease];
[self.tableView setBackgroundView:backgroundViews];
}
[self.navigationController pushViewController:controller animated:YES];
[controller release];
//tableView.backgroundView = backgroundViews;
//[self configureCell:cell atIndexPath:indexPath];
}
From your code you are only alloc-init your controller for iPad, for the iPhone, you do not allocate it and then when it comes to a line [controller release]; it has nothing to release!

You can display your new viewController using presentModalViewController method. I use it like this way:
- (IBAction)addNewBuidling:(id)sender
{
NewBuilding *new=[[NewBuilding alloc]initWithNibName:#"NewBuilding" bundle:nil];
new.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
new.modalPresentationStyle=UIModalPresentationFormSheet;
[self.navigationController presentModalViewController:new animated:YES];
new.view.superview.frame = CGRectMake(0, 0, 357 ,117);//it's important to do this after. Take a frame size exactly of your new viewController's size.
new.view.superview.center = self.view.center;
[new release];
}
This is how my NewBuilding viewController will appear on screen.
Edit 1:
In this written in presentModalViewController reference: "On iPhone and iPod touch devices, the view of modalViewController is always presented full screen." so for iPhone it may not serve your purpose.
if you want to display less details then you can use following option.
declare below code in .h file
UIWindow *alertWindow;
Write following code in .m file.
alertWindow = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; // you must release the window somewhere, when you do not need it anymore
alertWindow.windowLevel = UIWindowLevelAlert; // puts it above the status bar
alertWindow.backgroundColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:0.5];
/*CUSTOM VIEW obj*/.center = CGPointMake(alertWindow.frame.size.width/2, alertWindow.frame.size.height/2);
[alertWindow addSubview:/*PUT YOUR CUSTOM VIEW HERE*/];
[alertWindow setHidden:NO];
this code is display you custom view like UIAlertView.
you put above code in UITableView Delegate method.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {}
For hide window
[alertWindow setHidden:YES];
[alertWindow release]; alertWindow = nil;
I have added custom Badge on UISegmentControl. In Xcode 4.0.2 SDK 4.3 its working fine. But in Xcode 4.2 SDK 5.0 custom badge is not shown when another item is selected. I dont know why this happens? I'm using following code for IOS 4.3 Xcode 4.0.2:
- (void)viewDidLoad {
[super viewDidLoad];
super.tableView.backgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"wallpaper.png"]];
NSLog(#"Root View Loaded");
segmentedControl = [[UISegmentedControl alloc] initWithItems:
[NSArray arrayWithObjects:
#"Home",#"Surveys",#"Results",#"Create",#"Settings",
nil]];
[segmentedControl addTarget:self action:#selector(segmentAction:) forControlEvents:UIControlEventValueChanged];
segmentedControl.frame = CGRectMake(0, 0, 310, 40);
segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
segmentedControl.tintColor = [UIColor darkGrayColor];
segmentedControl.momentary = NO;
segmentedControl.highlighted = YES;
segmentedControl.selectedSegmentIndex = 0;
UIBarButtonItem *segmentBarItem = [[UIBarButtonItem alloc] initWithCustomView:segmentedControl];
NSArray *segmentBarArray = [NSArray arrayWithObjects:
segmentBarItem,nil];
[[self appDelegate] setSegmentedControl:segmentedControl];
[[self appDelegate] setSegmentBarArray:segmentBarArray];
[self setToolbarItems:[[self appDelegate] segmentBarArray] animated:NO];
[[self navigationController] setToolbarHidden:NO animated:YES];
[self.navigationItem setHidesBackButton:YES animated:YES];
self.navigationController.toolbar.tintColor = [UIColor blackColor];
int surveycount = [[self appDelegate] getUnreadSurveyCount];
surveyCountBadge = [CustomBadge customBadgeWithString:[NSString stringWithFormat:#"%d",surveycount]];
[surveyCountBadge setFrame:CGRectMake(105, -10, surveyCountBadge.frame.size.width, surveyCountBadge.frame.size.height)];
[segmentedControl addSubview:surveyCountBadge];
if (surveycount == 0) {
[surveyCountBadge setHidden:YES];
}else{
[surveyCountBadge setHidden:NO];
}
}
-(void)segmentAction:(id) sender{
UISegmentedControl *segmentedControl = (UISegmentedControl *)sender;
NSLog(#"selected index is %d",segmentedControl.selectedSegmentIndex);
if (segmentedControl.selectedSegmentIndex == 0) {
[self.navigationController popToRootViewControllerAnimated:YES];
} else if(segmentedControl.selectedSegmentIndex ==1){
surveyForMeViewController = [[SurveyForMeView alloc] initWithNibName:#"SurveyForMeView" bundle:nil];
[self.navigationController pushViewController:surveyForMeViewController animated:YES];
} else if(segmentedControl.selectedSegmentIndex ==2){
resultViewController = [[ResultView alloc] initWithNibName:#"ResultView" bundle:nil];
[self.navigationController pushViewController:resultViewController animated:YES];
} else if (segmentedControl.selectedSegmentIndex ==3) {
newSurveyViewController = [[NewSurveyView alloc] initWithNibName:#"NewSurveyView" bundle:nil];
[self.navigationController pushViewController:newSurveyViewController animated:YES];
} else if (segmentedControl.selectedSegmentIndex ==4) {
settingsViewControlle = [[SettingsView alloc] initWithNibName:#"SettingsView" bundle:nil];
[self.navigationController pushViewController:settingsViewControlle animated:YES];
}
}
Any thing else should I mention in this?
You are adding a subview to a segmentedControl. As you don't know how the system redraws the control when another item is selected, you cannot say if your view will be removed or not. Let the control, button or segmentedControl do its work and if you want to add a badge, add it as a subview of its parent.
[surveyCountBadge setFrame:CGRectMake(105.0f+segmentedControl.frame.origin.x,
-10.0f+sementedControl.frame.origin.y, surveyCountBadge.frame.size.width,
surveyCountBadge.frame.size.height)];
[[segmentedControl superView] addSubview: surveyCountBadge];
this is my code:
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
picker.showsCameraControls = NO;
picker.allowsEditing = NO;
picker.delegate = self;
picker.navigationBarHidden = YES;
picker.toolbarHidden = YES;
picker.wantsFullScreenLayout = YES;
UIView *overlay = [[UIView alloc] initWithFrame:CGRectZero];
overlay.backgroundColor = [UIColor greenColor];
overlay.alpha = 0.3;
overlay.clipsToBounds = NO;
UIButton *takePictureButton = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 1024, 1024)];
[takePictureButton addTarget:self action:#selector(takePictureButtonPressed:) forControlEvents:UIControlEventTouchUpInside];
takePictureButton.backgroundColor = [UIColor purpleColor];
[overlay addSubview:takePictureButton];
picker.cameraOverlayView = overlay;
[takePictureButton release];
[overlay release];
_currentPicker = picker;
[self presentModalViewController:picker animated:YES];
[picker release];
And it's look like on iPad 2 with iOS 4.3.2:
sorry, I can't post image
What I want is it can take picture when user tap anywhere on the screen.
Forgive my poor English.
I solved this question by myself:
just reset the size of cameraOverlayView after present UIImagePickerController.
code like this:
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
picker.showsCameraControls = NO;
picker.allowsEditing = NO;
picker.delegate = self;
UIButton *takePictureButton = [[UIButton alloc] initWithFrame:CGRectZero];
[takePictureButton addTarget:self action:#selector(takePictureButtonPressed:) forControlEvents:UIControlEventTouchUpInside];
picker.cameraOverlayView = takePictureButton;
[self presentModalViewController:picker animated:YES];
takePictureButton.frame = CGRectMake(0, 0, 1024, 1024);
[picker release];
[takePictureButton release];
Although it's not elegant, but it work :)
I need to display a view modally. The viewcontroller that needs to be displayed modally has to have a UIToolbar at the bottom. In this toolbar there are one uisegmentedcontroller with three elements. (Think of an tabbar).
In the viewcontroller that presents the modal viewcontroller I have:
-(IBAction)presentModally:(id)sender {
if (self.nvc == nil) {
MyModalViewController *vc = [[MyModalViewController alloc] init];
UINavigationController *navvc = [[UINavigationController alloc] initWithRootViewController:vc];
navvc.navigationItem.prompt = #"";
navvc.navigationBar.barStyle = UIBarStyleBlack;
[vc release];
self.nvc = navvc;
[navvc release];
}
[self presentModalViewController:self.nvc animated:YES];
}
MyModalViewController:
- (void)loadView {
[super loadView];
UIView *uiview = [[UIView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 320.0f, 460.0f)];
uiview.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
self.view = uiview;
[uiview release];
UIToolbar *toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0.0f, 436.0f, 320.0f, 44.0f)];
toolbar.barStyle = UIBarStyleBlack;
toolbar.autoresizingMask = UIViewAutoresizingFlexibleWidth;
NSArray *itemArray = [NSArray arrayWithObjects: #"One", #"Two", #"Three", nil];
UISegmentedControl *segCon = [[UISegmentedControl alloc] initWithItems:itemArray];
segCon.frame = CGRectMake(60, 4, 200, 36);
segCon.segmentedControlStyle = UISegmentedControlStyleBar;
segCon.tintColor = [UIColor darkGrayColor];
segCon.selectedSegmentIndex = 0;
[segCon addTarget:self action:#selector(changedSegment:) forControlEvents:UIControlEventValueChanged];
[toolbar addSubview:segCon];
self.segmentedControl = segCon;
[segCon release];
[[self navigationController].view addSubview:toolbar];
[toolbar release];
}
- (void)changedSegment:(id)sender {
UISegmentedControl *control = (UISegmentedControl *)sender;
int index = control.selectedSegmentIndex;
[[self navigationController] popViewControllerAnimated:NO];
[[self navigationController] pushViewController:[self.controllers objectAtIndex:index] animated:NO];
}
The viewcontrollers in the array are just normal UIViewControllers.
I have set this property in those classes to:
self.navigationItem.hidesBackButton = YES;
My question: Is this the proper way to achieve a UITabBarController behavior?
Haven't tested it, but It looks good, except that popViewControllerAnimated. I'd use popToRootViewControllerAnimated instead (In case a controller uses itself the navigationController).
Here I'm gettimg memory allocation problem at activity indicator and my code is:
- (id)init {
if (self = [super init]) {
self.title=#"Release Details";
contentView = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
contentView.backgroundColor = [UIColor clearColor];
self.view = contentView;
[contentView release];
CGRect frame = CGRectMake(0,0, 320,1500);
containerView = [[UIView alloc] initWithFrame:frame];
webView = [ [UIWebView alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
webView.backgroundColor = [UIColor colorWithPatternImage: [UIImage imageNamed:#"background1.png"]];
webView.delegate = self;
[containerView addSubview:webView];
CGRect activityViewframe = CGRectMake(20,8,20, 20);
progressInd = [[UIActivityIndicatorView alloc] initWithFrame:activityViewframe];
progressInd.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhite;
progressInd.autoresizingMask = (UIViewAutoresizingFlexibleLeftMargin |
UIViewAutoresizingFlexibleRightMargin |
UIViewAutoresizingFlexibleTopMargin |
UIViewAutoresizingFlexibleBottomMargin);
[containerView addSubview:progressInd];
[progressInd startAnimating];
progressInd.hidden = NO;
[progressInd stopAnimating];
[self.view addSubview:containerView];
isFetch=YES;
}
return self;
}
-(void) displayInProgressRightBarButton
{
UIView* rightBarButtonView = [ [UIView alloc] initWithFrame:CGRectMake(270,5,45, 35)];
[rightBarButtonView addSubview:progressInd];
UIBarButtonItem* buttonItem = [[UIBarButtonItem alloc] initWithCustomView:rightBarButtonView];
self.navigationItem.rightBarButtonItem = buttonItem;
[rightBarButtonView release];
[buttonItem release];
}
- (void)webViewDidStartLoad:(UIWebView *)webView
{
[self displayInProgressRightBarButton];
[progressInd startAnimating];
[UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
}
- (void)webViewDidFinishLoad:(UIWebView *)webView
{
[progressInd stopAnimating];
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
}
Also I released the progressInd in dealloc eventhough it showing memory allocation at
progressInd = [[UIActivityIndicatorView alloc] initWithFrame:activityViewframe];
in init.
can anyone help me to solve this.
Anyone's help will be much Appreciated.
You can (and should) release it right after adding it to the container view:
[containerView addSubview:progressInd];
[progressInd release];
The same for the container view itself:
[self.view addSubview:containerView];
[containerView release];
The containing view will retain the subview for you, so you can release it right after adding it.
