i am placing a toolbar at the top of my view with edit button.
For edit button i am giving action like edit the table as shown below.
- (IBAction)editModeForTable {
[tableview setEditing:YES animated:YES];
NSLog(#"edit button clicked ");
}
Now what i need is when i click on edit button i need to change this edit button to done button.
this is myscreen.
when ever i click on edit i need to set edit mode for table and change edit button to done.
similarly when ever i click on done button i need to change that done to edit button and edit mode should be false.
Update:
- (IBAction)editModeForTable {
if (buttonClickid == 1) {
[allLIsts setEditing:YES animated:YES];
mybutton.style = UIBarButtonSystemItemDone;
mybutton.title = #"Done";
buttonClickid = 2;
NSLog(#"mmm");
}
if (buttonClickid == 2) {
[allLIsts setEditing:NO animated:YES];
mybutton.style = UIBarButtonSystemItemEdit;
mybutton.title = #"Edit";
buttonClickid = 1;
NSLog(#"ppp");
}
NSLog(#"edit button clicked ");
}
this is button action where buttonclickid is int.
it executes both conditions why?
[btn setStyle:UIBarButtonItemStyleDone];
[btn setTitle:#"Done"];
Similiar to revert back.
btn is an IBOutlet connected to the button in Interface Builder, or your created UIBarButtonItem.
Your if logic is broken.
- (IBAction)editModeForTable {
if (![allLIsts isEditing]) {
[allLIsts setEditing:YES animated:YES];
mybutton.style = UIBarButtonSystemItemDone;
mybutton.title = #"Done";
NSLog(#"mmm");
}
else {
[allLIsts setEditing:NO animated:YES];
mybutton.style = UIBarButtonSystemItemEdit;
mybutton.title = #"Edit";
NSLog(#"ppp");
}
NSLog(#"edit button clicked ");
}

I have created a mapview, with page curl feature in it. The mapview is having a toolbar, with a page curl button. On clicking the button, the mapview page curls. Here is the code.
-(IBAction) onPageCurl:(id)sender{
pageCurlViewController = [[MyMapViewPageCurlViewController alloc] initWithNibName:#"MyMapViewPageCurlViewController" bundle:nil];
[pageCurlViewController.navigationController.toolbar setHidden:NO];
[pageCurlViewController setModalTransitionStyle:UIModalTransitionStylePartialCurl];
[pageCurlViewController setToolbarItems:toolbarItems];
[[self navigationController] presentModalViewController:pageCurlViewController animated:YES];
[pageCurlViewController getMapView:&mapView];
[pageCurlViewController release];
}
As the mapview page curls, I have a new viewcontroller underneath it. The new view controller has a segmented control with 3 segments.
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
[self.navigationController.toolbar setHidden:NO];
[directionSearchSegmentedControl addTarget:self action:#selector(segmentAction:) forControlEvents:UIControlEventValueChanged];
directionSearchSegmentedControl.selectedSegmentIndex = selectedIndex;
UIBarButtonItem *directionSearchSegmentedControlButton = [[[UIBarButtonItem alloc] initWithCustomView:directionSearchSegmentedControl] autorelease];
NSArray *toolbarItems = [NSArray arrayWithObjects: navigatorButton , flexibleSpace, directionSearchSegmentedControlButton, flexibleSpace, pageCurlButton, nil];
[self setToolbarItems:toolbarItems];
[self.navigationController.toolbar setHidden:NO];
}
I have standard/satellite/hybrid view of the map on clicking each segments in the segmented controller.
- (void)segmentAction:(id)sender
{
[self dismissModalViewControllerAnimated:YES];
if([sender selectedSegmentIndex] == 0){
selectedIndex = 0;
pageCurlMapView.mapType = MKMapTypeStandard;
}
if([sender selectedSegmentIndex] == 1){
selectedIndex = 1;
pageCurlMapView.mapType = MKMapTypeSatellite;
}
if([sender selectedSegmentIndex] == 2){
selectedIndex = 2;
pageCurlMapView.mapType = MKMapTypeHybrid;
}
if([sender selectedSegmentIndex] == 2){
}
directionSearchSegmentedControl.momentary = YES;
selectedIndex = directionSearchSegmentedControl.selectedSegmentIndex;
}
The page curl feature is working fine. As the page curls, as mentioned before, I have a segmented control in the new view. But the the segmented control is not working properly in IOS 6. I have debugged and checked. On the click of the segments, the control doesn't enter the event method.
Its still working fine in the previous versions of IOS, but not in IOS 6. Cant figure out, what is wrong. Help needed.
If you look at the Xcode console when the app launches, do you see a message like this:
Applications are expected to have a root view controller at the end of application launch
If so, then your you problem could be due to changes in how the root view controller needs to be set up for iOS 6.
See here for info on how to address the problem.
Sorry if this is kinda late, but I have been working on something similar in my app. Honestly, I just used a simple switch method in order to change the map type. The code is below.
- (IBAction)toggle:(id)sender {
switch ([sender selectedSegmentIndex]) {
case 0:
{
[self.mapView setMapType:MKMapTypeStandard];
}break;
case 1:
{
[self.mapView setMapType:MKMapTypeHybrid];
}break;
case 2:
{
[self.mapView setMapType:MKMapTypeSatellite];
}break;
}
}
Now I have not tried using this with multiple view controllers so this may only work with the one view controller. I just started programming on iOS so bear with me.. I'm gonna try to add the page curl effect to my app but all I have so far is a map view and a button that when it's pushed, zooms into the users location and the user is able to change the map type..
P.S. This is a Segmented Control set as a Value Changed action named "toggle" if that helps...
I initialize an activity indicator and in a button press action I start it animating and call the next view to display.
-(IBAction) downloadButtonPressed:(id)sender {
NSLog(#"Download Button Pressed");
indicator.hidden = NO;
[indicator startAnimating];
if (addviewcontroller == nil)
addviewcontroller = [[AddViewController alloc]init];
[self.view addSubview:addviewcontroller.view];
[addviewcontroller setModalTransitionStyle:UIModalTransitionStyleCrossDissolve];
[self presentModalViewController:addviewcontroller animated:YES];
}
When I press the button, the activity indicator doesn't start immediately. It starts when the other view is called. The indicator is displayed for a second, but when the button is pressed it takes some time to load the other view.
I dont know why the indicator shows for a second without starting.
Try this :
-(IBAction) downloadButtonPressed:(id)sender
{
NSLog(#"Download Button Pressed");
indicator.hidden = NO;
[indicator startAnimating];
[self performSelector:#selector(showController) withObject:nil afterDelay:0.1f];
}
- (void)showController {
if (addviewcontroller == nil)
addviewcontroller = [[AddViewController alloc]init];
[self.view addSubview:addviewcontroller.view];
[addviewcontroller setModalTransitionStyle:UIModalTransitionStyleCrossDissolve];
[self presentModalViewController:addviewcontroller animated:YES];
}
That should do the trick ;-)
EDIT
I just noticed that there is a problem in your code, you are adding your addviewcontroller twice. One by adding it as a subview of the actual view controller, and one by modally presenting another view controller. You should remove one of the statements from this function.
I am showing a some text and images in UIwebview in navigation based application. It also contains some link to the source of the data i.e the websites. It is showing it in perfect manner. But when user click on the back button it pop the previous viewcontroller and goes to it. But, What I want when user click on the link the back button must be converted into browser's back button and act like it.
Any suggestions/sample code or tutorial for it?
You can replace the navigation bar's back button with a browser back button whenever the UIWebView has the option to go back by doing something like this:
- (void)updateBackButton {
if ([self.webView canGoBack]) {
if (!self.navigationItem.leftBarButtonItem) {
[self.navigationItem setHidesBackButton:YES animated:YES];
UIBarButtonItem *backItem = [[[UIBarButtonItem alloc] initWithTitle:#"Back" style:UIBarButtonItemStylePlain target:self action:#selector(backWasClicked:)] autorelease];
[self.navigationItem setLeftBarButtonItem:backItem animated:YES];
}
}
else {
[self.navigationItem setLeftBarButtonItem:nil animated:YES];
[self.navigationItem setHidesBackButton:NO animated:YES];
}
}
- (void)webViewDidStartLoad:(UIWebView *)webView {
[self updateBackButton];
}
- (void)webViewDidFinishLoad:(UIWebView *)webView {
[self updateBackButton];
}
- (void)backWasClicked:(id)sender {
if ([self.webView canGoBack]) {
[self.webView goBack];
}
}
See First thing that you have to do is, that you have to hide the default back button, as follows below
self.navigationItem.hidesBackButton = YES;
After this you have to add a custom back button on the navigationbar as below:
UIButton *m_BackBtn = [UIButton buttonWithType:UIButtonTypeCustom];
m_BackBtn.frame = CGRectMake(4.0, 5.0+0.0, 100, 30);
[m_BackBtn setTitle:#"Back" forState:UIControlStateNormal];
[m_BackBtn addTarget:selfaction:#selector(BackButtonAction)forControlEvents:UIControlEventTouchUpInside];
[m_BackBtn retain];
[self.navigationController.navigationBar addSubview:m_BackBtn];
*And in the BackButtonAction Function *
-(void)BackButtonAction
{
[yourwebView goBack];
// Do your stuff as you required
}
Take a UIBarbuttonItem from XIB at the place of back button and you
can write following in its IBAction method Suppose your UIWebview
object is
UIWebView *web;
-(IBAction)goBack
{
[web goBack];
}
goBack is inbuilt method of UIWebView
I like #cduhn's approach above for it's simplicity, but it has the downside of losing the "<" on the Back button. See this answer if you want to keep the "real" back button (with it's "<" icon), but change the button's behavior:
https://stackoverflow.com/a/19132881/132542
For the web view history case here, this is the code I used in my delegate method:
-(BOOL) navigationShouldPopOnBackButton {
if (webView.canGoBack) {
// Then just go back in the web view
[webView goBack];
// return NO to keep the current view controller loaded
return NO;
}
else {
// no web history, so pop the view
return YES;
}
}
This is a bit tricky solution, may not be suggested. But this way you can maintain the back navigation animation on navigation bar.
var urlRequest: NSURLRequest?
////////
func webView(webView: UIWebView, shouldStartLoadWithRequest request: NSURLRequest, navigationType: UIWebViewNavigationType) -> Bool {
if navigationType == .LinkClicked {
//AViewController creates and pushes itself to the navigationController
let pushViewController = self.storyboard?.instantiateViewControllerWithIdentifier("AViewController") as! AViewController
pushViewController.urlRequest = request
self.navigationController?.pushViewController(pushViewController, animated: true)
return false
} else { //is initial request from push
return true
}
}
I have a button (a UINavigationBarItem) used for editing my UITableView, which only allows deletions. So when I press delete, the little red line comes up next to each cell, and I can delete each row.
When the button is pressed, the following function is called:
-(void)editButtonSelected:(id)sender {
if(self.editing)
NSLog(#"self.editing = true");
else
NSLog(#"self.editing = false");
if(self.editing) {
[super setEditing:NO animated:NO];
[tableView setEditing:NO animated:NO];
[tableView reloadData];
[leftButton setTitle:#"Delete"];
[leftButton setStyle:UIBarButtonItemStylePlain];
self.editing = false;
}
else {
[super setEditing:YES animated:YES];
[tableView setEditing:YES animated:YES];
[tableView reloadData];
[leftButton setTitle:#"Done"];
[leftButton setStyle:UIBarButtonItemStyleDone];
self.editing = true;
}
}
And it works fine. But only for a while. As soon as I introduce a new UIViewController, and then dismiss that controller, this delete function doesn't work on this main screen I have. It works fine until a new UIViewController is put on top. The button itself works fine, and the value of self.editing does get toggled between true and false correctly, but the little red lines do not show up. Why could this be happening?
I would guess that the target on your UINavigationBarItem is still set to the first view controller, not the subsequent view controllers that get pushed on the stack.
My App is having a search bar for searching records from the table view,which is populated by sqlite DB.
My problem is that when the view opens the "cancel" button is not enabled and also I cant touch on that, just like a image only.It is there but no action is with that.
when we click on that search bar text the cancel button will be changed to "done" it is enabled one.
so here is my code
this is my search bar view,see that cancel button.It is not enabled
- (void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar
{
//[newSearchBar setShowsCancelButton:YES animated:YES];
newSearchBar.autocapitalizationType = UITextAutocapitalizationTypeAllCharacters;
NSLog(#"search begin edit") ;
//searchString = searchBar.text;
//NSLog(#"print did edit searchstring : %#", searchString) ;
for(UIView *view in [searchBar subviews])
{
//shareItemId =newSearchBar.text;
if([view isKindOfClass:[NSClassFromString(#"UINavigationButton") class]]) {
[(UIBarItem *)view setTitle:#"Done"];
}
}
- (void)searchBarTextDidEndEditing:(UISearchBar *)searchBar
{
NSLog(#"searchBarTextDidEndEditing:");
[searchBar resignFirstResponder];
//[self dismissModalViewControllerAnimated:YES];
}
- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar
{
NSLog(#"searchBarSearchButtonClicked");
searchString = searchBar.text;
NSLog(#"search %#", searchBar.text);
[newSearchBar setShowsCancelButton:NO animated:YES];
[searchBar resignFirstResponder];
//[self dismissModalViewControllerAnimated:YES];
}
- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar
{
NSLog(#" searchBarCancelButtonClicked");
[searchBar resignFirstResponder];
shareItemName =newSearchBar.text;
[self dismissModalViewControllerAnimated:YES];
}
- (BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar {
NSLog(#"searchBarShouldBeginEditing");
[newSearchBar setShowsCancelButton:YES animated:YES];
return YES;
}
These are my delegates for that
Please check my code and give me the answer. I need to enable the "Cancel" button when the view is loaded and it action will be go back to previous view
I need like this
Or else how can I add a another cancel button on exciting cancel button.so that I can enable that.please give me all the details
You need to set the UISearchDisplayController to be ACTIVE, like this:
[mySearchDisplayController setActive:YES animated:YES];
or more simply:
mySearchDisplayController.active = YES;
My guess is that Apple made the UISearchBar in a way that the cancel button is disabled if the search text field is empty or not first responder.
This is make sense because you should not use the "Cancel" button to other purpose than actually canceling the search. and since there is no search to cancel - the button is disabled.
If you still want that the button will be active immediately when the view is presented, you can call at viewWillAppear: to [mySearchBar becomeFirstResponder];
This will cause to the keyboard to appear and the button will be enabled.
And then if the user hit cancel you can intercept it to go back to the previous view. (I'm not sure if apple will like this behavior).
Sample code:
-(void) viewWillAppear : (BOOL) animated
{
[super viewWillAppear:animated];
// Make keyboard pop and enable the "Cancel" button.
[self.mySearchBar becomeFirstResponder];
}
Here's what I did to always enable the cancel button, even when the search field is not first responder.
I'm calling this method whenever I call resignFirstResponder on the search field
- (void)enableCancelButton {
for (UIView *view in self.searchBar.subviews) {
if ([view isKindOfClass:[UIButton class]]) {
[(UIButton *)view setEnabled:YES];
}
}
}
This works, but I'm not sure whether it will pass App Store verification yet, so use it at your own risk. Also, this probably only works if the cancel button is the only button you are using with the search field.
This works to reenable the cancel button as of iOS 8:
private func enableButtonsInSubviews(view: UIView) {
if let view = view as? UIButton {
view.enabled = true
}
for subview in view.subviews {
enableButtonsInSubviews(subview)
}
}
