Remove background image from navigationBar when pushing TableViewControllers - iphone

I have a navigation based app where I push TableViewControllers onto the stack. I would like to add a background image to the first TableViewControllers. Not a color, but an image.
I have added a categroy for setting and removing the background image.
#implementation UINavigationBar (UINavigationBarCategory)
-(void)setBackgroundImage:(UIImage*)image withTag:(NSInteger)bgTag {
if(image == NULL){ //might be called with NULL argument
return;
}
UIImageView *aTabBarBackground = [[UIImageView alloc]initWithImage:image];
aTabBarBackground.frame = CGRectMake(self.frame.size.width/2-51,0,102,44);
aTabBarBackground.tag = bgTag;
[self addSubview:aTabBarBackground];
[self sendSubviewToBack:aTabBarBackground];
[aTabBarBackground release];
}
- (void) clearBackgroundImage {
NSArray *subviews = [self subviews];
for (int i = [subviews count] - 1; i >= 0; i--) {
if ([[subviews objectAtIndex:i] isMemberOfClass:[UIImageView class]]) {
[[subviews objectAtIndex:i] removeFromSuperview];
}
}
}
And am setting the image with the following code:
[[navigationController navigationBar] setBackgroundImage:[UIImage imageNamed:#"AppTop-Banner.png"]];
The background image is being added properly but for the subsequent pushed into view Tableviewcontrollers, I can't remove the image by calling the following:
#implementation SecondTableViewController
-(id) init {
self = [super init];
if (self != nil) {
self.title = #"Categories";
}
}
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
[self.navigationController.navigationBar clearBackgroundImage];
}
In this case "clearBackgroundImage" is never being called and the background image is still there, with the title overlapping the image. I am not sure if I can refer to the navigationBar this way. Maybe self.navigationController.navigationBar is not the right way to call the relevant navigationBar Can somebody throw some light please.

How can I make a custom view of the 'delete-button' when performing commitEditingStyle within a UITableView

I would like to customize the delete button which is shown when performing the 'swipe to left'-action on a tableview cell. I currently set up a subclass of a UITableViewCell but also want to customize the delete-button which is being shown.
My goal is to place three buttons when swiping.
I choose for another implementation where I was using a UIScrollview in each cell.
http://www.teehanlax.com/blog/reproducing-the-ios-7-mail-apps-interface/
Accepted answer will not work on iOS 7, as there is now UITableViewCellContentView in between. So subviews loop now should look like this(if you want to support older iOS versions too, use currently accepted answer for iOS 6.1-)
for (UIView *subview in self.subviews) {
for (UIView *subview2 in subview.subviews) {
if ([NSStringFromClass([subview2 class]) rangeOfString:#"Delete"].location != NSNotFound) {
// Do whatever you want here
}
}
}
This might help you.
- (void)willTransitionToState:(UITableViewCellStateMask)state
{
[super willTransitionToState:state];
if ((state & UITableViewCellStateShowingDeleteConfirmationMask) == UITableViewCellStateShowingDeleteConfirmationMask)
{
for (UIView *subview in self.subviews)
{
if ([NSStringFromClass([subview class]) isEqualToString:#"UITableViewCellDeleteConfirmationControl"])
{
UIImageView *deleteBtn = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 64, 33)];
[deleteBtn setImage:[UIImage imageNamed:#"arrow_left_s11.png"]];
[[subview.subviews objectAtIndex:0] addSubview:deleteBtn];
}
}
}
}
Referenced from:

Custom Delete button On Editing in UITableView Cell
-(void)willTransitionToState:(UITableViewCellStateMask)state{
NSLog(#"EventTableCell willTransitionToState");
[super willTransitionToState:state];

{
UIImageView *deleteBtn = [[UIImageView alloc]initWithFrame:CGRectMake( 320,0, 228, 66)];
[deleteBtn setImage:[UIImage imageNamed:#"BtnDeleteRow.png"]];

[self recurseAndReplaceSubViewIfDeleteConfirmationControl:self.subviews];
[self performSelector:#selector(recurseAndReplaceSubViewIfDeleteConfirmationControl:) withObject:self.subviews afterDelay:0];
}
}
The solutions above didn't work for me for iOS 7, at - (void)willTransitionToState:, the delete button wasn't in the view heirarchy so I wasn't able to manipulate anything. I ended up doing everything on - (void)didTransitionToState:. The example below was specifically for when my cells had some spacing at the top so I'm altering the frame of the delete button. If you want to customize the delete button, you can just add a view on top of the delete button or replace it with your own UIButton
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
//your own stuff
//for some reason, editingAccessoryView cannot be nil and must have a non-CGRectZero frame
self.editingAccessoryView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 1, 1)];
}
return self;
}
- (void)didTransitionToState:(UITableViewCellStateMask)state
{
[super didTransitionToState:state];
if ((state & UITableViewCellStateShowingDeleteConfirmationMask) == UITableViewCellStateShowingDeleteConfirmationMask)
{
UIView *deleteButton = [self deleteButtonSubview:self];
if (deleteButton) {
CGRect frame = deleteButton.frame;
frame.origin.y += defined_padding;
frame.size.height -= defined_padding;
deleteButton.frame = frame;
}
}
}
- (UIView *)deleteButtonSubview:(UIView *)view
{
if ([NSStringFromClass([view class]) rangeOfString:#"Delete"].location != NSNotFound) {
return view;
}
for (UIView *subview in view.subviews) {
UIView *deleteButton = [self deleteButtonSubview:subview];
if (deleteButton) {
return deleteButton;
}
}
return nil;
}

How do I make the bottom bar with dots of a UIPageViewController translucent?

I'm in the process of making a tutorial, and I'm trying to emulate the style of Path's tutorial like so:
http://www.appcoda.com/wp-content/uploads/2013/06/UIPageViewController-Tutorial-Screen.jpg
My issue is that if set the delegate method as so:
- (NSInteger)presentationCountForPageViewController:(UIPageViewController *)pageViewController {
// The number of items reflected in the page indicator.
return 5;
}
Then I get this stupid black bar under the dots:
http://i.stack.imgur.com/pUEdh.png
Is there a way to make this bar translucent in a way thats similar to setting a UINavigationBar to translucent?
It is very easy to make it work. You just only have to make the pageviewcontroller taller, and place a PageControl into the XIB file.
The trick is put the PageControl in the foreground (and all the other common controls) at the beginning, and update the content of the PageControl with the PageViewController. Here is the code:
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
self.pageController = [[UIPageViewController alloc] initWithTransitionStyle:UIPageViewControllerTransitionStyleScroll navigationOrientation:UIPageViewControllerNavigationOrientationHorizontal options:nil];
self.pageController.dataSource = self;
// We need to cover all the control by making the frame taller (+ 37)
[[self.pageController view] setFrame:CGRectMake(0, 0, [[self view] bounds].size.width, [[self view] bounds].size.height + 37)];
TutorialPageViewController *initialViewController = [self viewControllerAtIndex:0];
NSArray *viewControllers = [NSArray arrayWithObject:initialViewController];
[self.pageController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:NO completion:nil];
[self addChildViewController:self.pageController];
[[self view] addSubview:[self.pageController view]];
[self.pageController didMoveToParentViewController:self];
// Bring the common controls to the foreground (they were hidden since the frame is taller)
[self.view bringSubviewToFront:self.pcDots];
[self.view bringSubviewToFront:self.btnSkip];
}
- (UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerBeforeViewController:(UIViewController *)viewController {
NSUInteger index = [(TutorialPageViewController *)viewController index];
[self.pcDots setCurrentPage:index];
if (index == 0) {
return nil;
}
index--;
return [self viewControllerAtIndex:index];
}
- (UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerAfterViewController:(UIViewController *)viewController {
NSUInteger index = [(TutorialPageViewController *)viewController index];
[self.pcDots setCurrentPage:index];
index++;
if (index == 3) {
return nil;
}
return [self viewControllerAtIndex:index];
}
- (TutorialPageViewController *)viewControllerAtIndex:(NSUInteger)index {
TutorialPageViewController *childViewController = [[TutorialPageViewController alloc] initWithNibName:#"TutorialPageViewController" bundle:nil];
childViewController.index = index;
return childViewController;
}
- (NSInteger)presentationCountForPageViewController:(UIPageViewController *)pageViewController {
// The number of items reflected in the page indicator.
NSInteger tutorialSteps = 3;
[self.pcDots setNumberOfPages:tutorialSteps];
return tutorialSteps;
}
- (NSInteger)presentationIndexForPageViewController:(UIPageViewController *)pageViewController {
// The selected item reflected in the page indicator.
return 0;
}
The same effect can be achieved simply by subclassing UIPageViewController and overriding viewDidLayoutSubviews as follows:
-(void)viewDidLayoutSubviews {
UIView* v = self.view;
NSArray* subviews = v.subviews;
// Confirm that the view has the exact expected structure.
// If you add any custom subviews, you will want to remove this check.
if( [subviews count] == 2 ) {
UIScrollView* sv = nil;
UIPageControl* pc = nil;
for( UIView* t in subviews ) {
if( [t isKindOfClass:[UIScrollView class]] ) {
sv = (UIScrollView*)t;
} else if( [t isKindOfClass:[UIPageControl class]] ) {
pc = (UIPageControl*)t;
}
}
if( sv != nil && pc != nil ) {
// expand scroll view to fit entire view
sv.frame = v.bounds;
// put page control in front
[v bringSubviewToFront:pc];
}
}
[super viewDidLayoutSubviews];
}
Then there is no need to maintain a separate UIPageControl and such.
Swift 3 snippet
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
if let scrollView = view.subviews.filter({ $0 is UIScrollView }).first,
let pageControl = view.subviews.filter({ $0 is UIPageControl }).first {
scrollView.frame = view.bounds
view.bringSubview(toFront:pageControl)
}
}
Here's a conversion of Zerotool's solution into Swift 2.1, though there's probably a more elegant way to write it:
override func viewDidLayoutSubviews() {
var scrollView: UIScrollView?
var pageControl: UIPageControl?
// If you add any custom subviews, you will want to remove this check.
if (self.view.subviews.count == 2) {
for view in self.view.subviews {
if (view.isKindOfClass(UIScrollView)) {
scrollView = view as? UIScrollView
} else if (view.isKindOfClass(UIPageControl)) {
pageControl = view as? UIPageControl
}
}
}
if let scrollView = scrollView {
if let pageControl = pageControl {
scrollView.frame = self.view.bounds
self.view.bringSubviewToFront(pageControl)
}
}
super.viewDidLayoutSubviews()
}
I don't think you can change the behavior of UIPageViewController, so it seems likely that the Path app uses its own view controller. You can do the same: create your own container view controller that uses a UIPageControl to indicate the current page.
You can simply adjust the alpha of the UIPageViewController's UIPageControl.
First, you should retrieve it from the UIPageViewController like so:
- (UIPageControl *)getPageControlForPageViewController:(UIPageViewController *)pageViewController {
for (UIView *subview in self.pageViewController.view.subviews) {
if ([subview isKindOfClass:[UIPageControl class]]) {
return (UIPageControl *) subview;
}
}
return nil;
}
Next, make use of the function. I've made a property on my ViewController called childPageControl. Give it the UIPageViewController's UIPageControl:
self.childPageControl = [self getPageControlForPageViewController:self.pageViewController];
Next, you can adjust the alpha to give a translucent effect:
self.childPageControl.alpha = .5;
You're very limited in what you can do to affect the UIPageViewController's UIPageControl, but you can at least achieve this with little effort.
Small hack I found today..
Please see the code below.
self.pageController.dataSource = self;
CGRect rect = [self.view bounds];
rect.size.height+=37;
[[self.pageController view] setFrame:rect];
NSArray *subviews = self.pageController.view.subviews;
UIPageControl *thisControl = nil;
for (int i=0; i<[subviews count]; i++) {
if ([[subviews objectAtIndex:i] isKindOfClass:[UIPageControl class]]) {
thisControl = (UIPageControl *)[subviews objectAtIndex:i];
}
}
UIView *tempview = [[UIView alloc] initWithFrame:CGRectMake(0, -30, 320, 40)];
[tempview addSubview:thisControl];
thisControl.pageIndicatorTintColor = [UIColor lightGrayColor];
thisControl.currentPageIndicatorTintColor = [UIColor greenColor];
[self.view addSubview:tempview];
this code is in Swift
Add following in your UIPageViewController
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
for view in self.view.subviews {
if view.isKindOfClass(UIScrollView) {
view.frame = UIScreen.mainScreen().bounds
} else if view.isKindOfClass(UIPageControl) {
view.backgroundColor = UIColor.clearColor()
}
}
}
I wanted to do a similar effect in the app I was working on - I used a UIPageViewController with a separate UIPageControl.
This lets you place the UIPageControl anywhere you'd like in the view, including over the top of the UIPageViewController, and you keep its active page dot up to date via the UIPageViewController delegate method:
- (void)pageViewController:(UIPageViewController *)pageViewController
didFinishAnimating:(BOOL)finished
previousViewControllers:(NSArray<UIViewController *> *)previousViewControllers
transitionCompleted:(BOOL)completed {
if (completed) {
self.pageControl.currentPage = [self.pageViewControllers indexOfObject:pageViewController.viewControllers.firstObject];
}
}
No need to traverse the subview hierarchy trying to find the internal UIPageViewController page control, nor having to resize the contents of the internal scrollview.
Hope this helps.
I solve using this code:
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
self.namesImage = #[#"page1.png", #"page2.png", #"page3.png", #"page4.png"];
self.pageViewController = [self.storyboard instantiateViewControllerWithIdentifier:#"PageViewController"];
self.pageViewController.dataSource = self;
TutorialContentViewController *startingViewController = [self viewControllerAtIndex:0];
NSArray *viewControllers = #[startingViewController];
[self.pageViewController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:NO completion:nil];
[self addChildViewController:self.pageViewController];
[self.view addSubview:self.pageViewController.view];
[self.pageViewController didMoveToParentViewController:self];
[[UIPageControl appearance] setPageIndicatorTintColor:[UIColor grayColor]];
[[UIPageControl appearance] setCurrentPageIndicatorTintColor:[UIColor whiteColor]];
[[UIPageControl appearance] setBackgroundColor: [[UIColor blackColor] colorWithAlphaComponent:0.1f]];
[[UIPageControl appearance] setOpaque:YES];
}
Swift 5.2
you can use this code for your requirment
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
if let myScrollView = view.subviews.filter({ $0 is UIScrollView }).first,
let myPageControl = view.subviews.filter({ $0 is UIPageControl }).first {
myScrollView.frame = view.bounds
view.bringSubviewToFront(myPageControl)
}
}
I found an other workarround that fits me better.
I reuse the code given by zerotool to get the UIPageControl (var called pageControl) and the UIScrollView (var called pageView) used by the UIPageViewController.
Once that done in the viewDidLoad, I just prevent clip subview of pageView and let the content spread more to be beneath the UIPageControl.
The pageControl is beneath the pageView so we have to manually make it come in front.
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
if(
[[[self view] subviews] count] == 2
)
{
UIScrollView* pageView = nil;
UIPageControl* pageControl = nil;
UIView* selfView = self.view;
NSArray* subviews = selfView.subviews;
for( NSInteger i = 0 ; i < subviews.count && ( pageView == nil || pageControl == nil ) ; i++ )
{
UIView* t = subviews[i];
if( [t isKindOfClass:[UIScrollView class]] )
{
pageView = (UIScrollView*)t;
}
else if( [t isKindOfClass:[UIPageControl class]] )
{
pageControl = (UIPageControl*)t;
}
}
if( pageView != nil && pageControl != nil )
{
[pageView setClipsToBounds:NO];
[selfView bringSubviewToFront:pageControl];
}
}
}
Once I get my pageView covering the space occupied by the pageControl but under the pageControl, I just have to adjust the nib file use for each viewController displayed as page :
base view should not clip
the first and only subview :
should have constraint to set bottom to -37 (or more if you need but 37 is the size of the pageControl) from bottom of superview
should clip content

If UITableview is empty show image

I am looking for 3 hours now on Google how to remove the tableview and show an image when the tableview is empty (have no more rows). Does someone know this? I know it's possible, because I saw it on many apps.
What I could find was:
// Check if table view has any cells
int sections = [self.tableView numberOfSections];
BOOL hasRows = NO;
for (int i = 0; i < sections; i++)
hasRows = ([self.tableView numberOfRowsInSection:i] > 0) ? YES : NO;
if (sections == 0 || hasRows == NO)
{
UIImage *image = [UIImage imageNamed:#"test.png"];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
// Add image view on top of table view
[self.tableView addSubview:imageView];
// Set the background view of the table view
self.tableView.backgroundView = imageView;
}
where to put this?
Thanks!
If your using Storyboard just put your view behind your UITableView
If your array of data is empty when creating it, simply hide your UITableView to show the "empty table" view behind it.
[tableView setHidden:YES];

UITableView is a (non direct) subclass of UIView, so what you want to do is easy.
Say that you have this table view as subview of your view controller's view. This case you just create another view with the same frame as the table view, then you remove your table view from the superview, and add the newly created view as subview of your view controller's view. So simply:
UIImageView* view= [[UIImageView alloc] initWithImage: yourImage];
view.frame= tableView.frame;
[tableView removeFromSuperview];
[self.view addSubview: view];
Put it on - (void)viewDidAppear. Good luck ;)

iOS : Cancel a Void function

I have created a method for example changeColor for calling the method we use
[self changeColor];
but how can I cancel these method ?
Edited :
here is my code I have several buttons which they add some image to the image view
- (void) setImagesFrame1 {
NSMutableArray *imageArray = [[NSMutableArray alloc]initWithCapacity:12];
for (int i = 0; i <= 12; i++) {
NSString *fileName = [NSString stringWithFormat:#"a%d.png",i];
UIImage *j = [UIImage imageNamed:fileName];
UIImageView *tempImage = [[UIImageView alloc]initWithImage:j];
[imageArray addObject:tempImage];
[self createPageWithImage:tempImage forPage:i];
}
}
- (void) setImagesFrame2 {
NSMutableArray *imageArray = [[NSMutableArray alloc]initWithCapacity:12];
for (int i = 0; i <= 12; i++) {
NSString *fileName = [NSString stringWithFormat:#"s%d.png",i];
UIImage *j = [UIImage imageNamed:fileName];
UIImageView *tempImage = [[UIImageView alloc]initWithImage:j];
[imageArray addObject:tempImage];
[self createPageWithImage:tempImage forPage:i];
}
}
and so on ...
I call my methods with this action :
- (IBAction)openFrames:(UIButton *)sender {
[captureView addSubview:framesPreviewView];
[framesPreviewView sendSubviewToBack:captureView];
framesPreviewView.frame = CGRectMake(img.bounds.origin.x, img.bounds.origin.y, img.bounds.size.width, img.bounds.size.height);
//buttons
if (sender == frame1) { [self setImagesFrame1]; }
if (sender == frame2) { NSLog(#"frame2"); }
if (sender == frame3) { [self setImagesFrame3]; NSLog(#"frame3"); }
}
when I press frame1 button the images will be added to my view , the problem is when I press frame2 button the images of this method also add to my view I need avoid this situation , it means when I touch every button the methods of other button should be canceled
To leave a void function execute the return statement...
return;
The last view on your subview array will be the image, You should use the method [view removeFrom superView];
However, to do that you need to use fast enumeration(for-In loop) over the subviews array.
If you want to be completely sure , you can check the retuned object, if it belongs to UIImageView Class. Then you should execute remaining statements in you setImages method.
Example: `
UIView *tempView;
for(tempView in self.subviews) {
if([tempView isKindOfClass:[UIImageView class] ]){
[tempView removeFromSuperView];
}
}
`
You can:
disable frame2 button when frame1 is pressed
enable frame2 button when setImagesFrame1 ended
Something like this:
- (void) setImagesFrame1 {
frame2.enabled = NO;
[... your code ...]
frame2.enable;
}
So if someone press button 1, he can't press button 2 (and redraw something) until all operations are completed.

Customizing search bar in iPhone application Development

In my application I have to add a search bar at the head of the tableview. I am able to add the searchbar but problem is without adding default search bar of ios can i add my customize search bar?? I am giving an image to see what types of search bar will be there...
you can subclass the UISearchBar and override the layoutSubviews method :
- (void)layoutSubviews {
UITextField *searchField;
NSUInteger numViews = [self.subviews count];
for(int i = 0; i < numViews; i++) {
if([[self.subviews objectAtIndex:i] isKindOfClass:[UITextField class]]) { //conform?
searchField = [self.subviews objectAtIndex:i];
}
}
if(!(searchField == nil)) {
searchField.textColor = [UIColor whiteColor];
[searchField setBackground: [UIImage imageNamed:#"yourImage.png"] ];
[searchField setBorderStyle:UITextBorderStyleNone];
}
[super layoutSubviews];
}
Also you can :
//to clear searchbar backgraound
- (void) clearSearchBarBg
{
for (UIView *subview in theSearchBar.subviews)
{
if ([subview isKindOfClass:NSClassFromString(#"UISearchBarBackground")])
{
[subview removeFromSuperview];
break;
}
}
}
//display showSearchButtonInitially in a keyboard
- (void)showSearchButtonInitially
{
UIView * subview;
NSArray * subviews = [theSearchBar subviews];
for(subview in subviews)
{
if( [subview isKindOfClass:[UITextField class]] )
{
NSLog(#"setEnablesReturnKeyAutomatically");
[((UITextField*)subview) setEnablesReturnKeyAutomatically:NO];
((UITextField*)subview).delegate=self;
[((UITextField*)subview) setEnabled:TRUE];
((UITextField*)subview).borderStyle = UITextBorderStyleNone;
break;
}
}
}
Look for Apple DOC for UISearchBar
You have bunch of methods there to get whatever you want
You can get UITextView Inside the search bar by
UITextField *textField = [searchBar.subviews objectAtIndex:2];
if ([textField isKindOfClass:[UITextField class]]) {
//Do your customization
}
Again look for AppleDoc for UITextField. You have bunch of methods for that also.
Yeah definitely. You can make your custom search bar (which is a sub-class of UIView) and add it as subview to the tableHeaderView.
[[searchBarDesign.subviews objectAtIndex:0] removeFromSuperview];
here searchBarDesign is my searchBar name.
I think it's better just set all properties of UISearchBar when it is loaded.
#interface MySearchBar : UISearchBar
