I need to have a Searchbar inside a ViewController as the picture bellow. I don't wanna use UItableViewcontroller. Is it possible to have this searchbar that will help me to query in a NSMutableArray thanks to NSpredicate ?
My Goal
After Searching showing the results of the array in the View "white view".
Yes, It is possible.
You can create a search bar programmatically.
First,Add UISearchBarDelegate Protocol in .h (header) file.
#interface ViewController : UIViewController<UISearchBarDelegate>
Then, Create UISearchBar and add as subview in your view.
UISearchBar searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(30, 80, screen.size.width-60, 40)]; //give your frame x,y and width and height
searchBar.placeholder = #"Enter City Name";
searchBar.delegate = self;
//searchBar.hidden = NO;
[self.view addSubview:searchBar];
Now, Implement delegate methods
- (void)searchBarSearchButtonClicked:(UISearchBar *)aSearchBar{
//your code when search button clicked
}
-(void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText {
//your code when you are entering text in search bar
}

I have different xib files with NSViewController attached to them. (Screenshot below)
One of xib file called StartMenuViewController which has a button. I want to click that button and change the view to DetectingUSBViewController.(Screenshot below)
The IBAction of that button is in StartMenuViewController.m file.
And I use AppController.m to control my main xib view.(NSWindow + NSView) (Screenshot below)
When the application runs, I try to initialize the StartMenuViewController fist by doing the following thing in my AppController.m file.
-(void)awakeFromNib{
[self initialize];
}
-(void) initialize
{
#autoreleasepool {
//mainViewController is a NSViewController and _mainView is a NSView which connect with Custom View in main xib
self.mainViewController = [[[StartMenuViewController alloc]initWithNibName:StartMenuView bundle:nil]autorelease];
[_mainView addSubview:[_mainViewController view]];
}
}
It works fine and it will show the StartMenuViewController.xib on the window at first, but I do not know how to change the view after clicking the button(FIND USB DRIVE). I want the current view changes to DetectingUSBViewController.xib.
Simplest way possible, assuming you have tied your USB button properly in, do the following :
- (IBAction)usbButton:(UIButton *)sender {
DetectingUSBViewController *second = [[DetectingUSBViewController alloc] initWithNibName:#"DetectingUSBView" bundle:nil];
[self presentViewController:second animated:YES completion:nil];
}
load the DetectingUSBViewController in startMenuViewController as DetectingUSBViewController* v1 = [[ViewCont1 alloc] initWithNibName:#"ViewCont1" bundle:nil]; now add or replace the view as [v1 view] in view where you want to add/replace.
You need to hook up your button to send an IBAction
You need a 'View for DetectingUSBViewController.xib'
=> one way (iOS like) is to use a ViewController. Subclass NSViewController and then alloc init a DetectingUSBViewController
Add the view. Don't present the VC (as there is no such thing in OSX)
//button click action
- (IBAction)usbButton:(UIButton *)sender {
//! Retain the VC
Self.detectingUSBViewController = [[DetectingUSBViewController alloc] initWithNibName:#"DetectingUSBView" bundle:nil];
//add the view
[_mainView addSubview:[_detectingUSBViewController view]];
}
I have a TableView with a search bar. But I want to add another view (lets say a label) in to the TableView (so it scrolls with the tableview) . For an example, if you open iPhones Phone Contacts application, under All Numbers, you can see a lable called "My Number:". Which must be at the same hierarchical level as the searchbar. I tried to add a new label just above the search bar, but storyboards don't allow me to do that.
In here if I drag and drop a UILabel to this hierarchy it either replaces the searchbar at the top , or the label drops inside of the prototype cell. There is no other way of showing searchbar and Label both at once.
Is there any way of doing this?
Create a separate view outside the view controller's view (or inside, it doesn't matter. you can even create this programmatically) and link it to an IBOutlet myCustomView.
Create an IBOutlet searchBar and link your UISearchBar
in viewDidLoad; you can use
[searchBar addSubView:myCustomView];
and add your custom view above the search bar.
you can show/hide (myCustomView.hidden = YES / NO) the custom view or add and remove it from superview whenever you need.
ex.
- (IBAction)didTapShowCustomHeaderButton {
myCustomView.hidden = NO;
}
- (IBAction)didTapHideCustomHeaderButton {
myCustomView.hidden = YES;
}
add the below two delegates in the code
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
UILabel *label = [[[UILabel alloc] initWithFrame:CGRectMake(10, 10, 100, 30)] autorelease];
label.text = #"My Label";
label.backgroundColor = [UIColor clearColor];
return label;
}
-(CGFloat)tableView:(UITableView*)tableView heightForHeaderInSection:(NSInteger)section{
return 30 // this height should be equivalent to the myLabel height u declared in headerView above
}
I have the following situation. I have a view controller (ContentController) with 3 buttons at the top. Below I added a second view (contentView), this view should display content that are behind those 3 buttons. So every time I press a button, the contentView changes. So what I did was created three addition controllers.
FirstController.m, FirstController.h, FirstController.xib
SecondController.m, SecondController.h, SecondController.xib,
ThirdController.m, ThirdController.h, ThirdController.xib,
in my ContentController.m I added 3 IBActions that handles the change.
#interface ViewController ()
#property (nonatomic,strong) UIViewController *nextController;
#end
#implementation ViewController
#synthesize nextController = _nextController;
-(IBAction)chooseFirstController:(id)sender {
_nextController = [[FirstController alloc] initWithNibName:#"FirstController" bundle:nil];
[self.contentView addSubview:_nextController.view];
}
-(IBAction)chooseSecondController:(id)sender{
_nextController = [[SecondController alloc] initWithNibName:#"SecondController" bundle:nil];
[self.contentView addSubview:_nextController.view];
}
-(IBAction)chooseThirdController:(id)sender{
_nextController = [[ThirdViewController alloc] initWithNibName:#"ThirdViewController" bundle:nil];
[self.contentView addSubview:_nextController.view];
}
My first and ThirdController just showing tableviews inside the contentView of contentController. But in my secondController I used a gridView for displaying items. Now when I press a cell, it should go to a detailViewController, whichs shows more information about that cell. So in my cellForRowAtIndex I did the following.
- (void)gridView:(NRGridView *)gridView didSelectCellAtIndexPath:(NSIndexPath *)indexPath
{
NSLog(#"cell clicked");
PlayerDetailController *playerController = [[PlayerDetailController alloc]initWithNibName:#"PlayerDetailController" bundle:nil];
[playerController setLblTest:#"hooray this works"];
[self.view addSubview:playerController.view];
}
It correctly executes setLblTest and also showing the detailViewcontroller inside my ContentView. But it don't changes the label. to my #"hooray" this works. But although as you can see in my log it passes it correctly.
#synthesize testLabel = _testLabel;
#synthesize lblTest = _lblTest;
-(void)setLblTest:(NSString *)lblTest{
if(![_lblTest isEqual:lblTest]){
_lblTest = lblTest;
}
NSLog(#"log komt %#",lblTest);
[_testLabel setText:lblTest];
}
LOG
RacingGenk[567:c07] log komt hooray this works
Hope this clarifies more my problem
Thank you
To get the label to update, you'll need to change your code to look like this.
self.testLabel.text = lblTest;
I have an app with a tab bar controller (2 tabs). In one tab view controller, a button leads to an alert window. I want one button of the alert window to call a table view containing possible answers. I want that table view to have a done button and a title. I think that means a navigation controller has to be used. But most everything I can find on navigation controllers assumes a much more complicated situation. Here's part of the alert window logic:
-(void) alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (buttonIndex == 2) {
AnswersViewController *aVC = [[AnswersViewController alloc] init];
[self presentViewController:aVC
animated:YES
completion:NULL];
}
}
And AnswersViewController looks like this:
#interface AnswersViewController : UITableViewController
#end
#implementation AnswersViewController
- (id) init
{
self = [super initWithStyle:UITableViewStylePlain];
return self;
}
- (id) initWithStyle:(UITableViewStyle)style
{
return [self init];
}
- (void)viewDidLoad
{
[super viewDidLoad];
[[self view] setBackgroundColor:[UIColor redColor]];
}
#end
This code all works as expected (an empty red UITableView appears).
Two questions I guess: 1. Is there a simple modification to what I have that can give me a done button and title in my table view? 2. If I have to go to a navigation controller (probably), how can I make a bare-bones navigation controller with a done button and title and embed the table view within it? Oh, and I want to do this programatically. And I think I prefer the done button and title to be in the navigation bar, no tool bar desired. Thanks!
To get what you are looking for, you do need to use a UINavigationController. That will provide the UINavigationBar where you can display a title and also buttons.
To implement this with a UINavigationController, you want to do smoothing like this (assuming you are using ARC, so you don't need to worry about memory management):
-(void) alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (buttonIndex == 2) {
AnswersViewController *aVC = [[AnswersViewController alloc] init];
//Make our done button
//Target is this same class, tapping the button will call dismissAnswersViewController:
aVC.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:#selector(dismissAnswersViewController:)];
//Set the title of the view controller
aVC.title = #"Answers";
UINavigationController *aNavigationController = [[UINavigationController alloc] initWithRootViewController:aVC];
[self presentViewController:aNavigationController
animated:YES
completion:NULL];
}
}
Then you would also implement - (void)dismissAnswersViewController:(id)sender in the same class as the UIAlertView delegate method (based on the implementation I have here).
Hope this helps!
I'm curious about how to implement a drop down menu from a UIBarButtonItem like in the portrait orientation on iPad's split view. How is this done? I would have tried searching for it myself, but I don't really know exactly what I should be searching for.
Thanks in advance!
Make a new UIView class(this will be the view that will be shown in the popover)
Then in the .h of the class were you want to open this popover
#interface TheClassWerePopoverIsShown : UIViewController {
UIPopoverController *popover;
}
in the .m under the barbuttonitem click action add this
if ([popover isPopoverVisible]) {
[popover dismissPopoverAnimated:YES];
}
else {
THECLASSTOSHOW *popie = [[THECLASSTOSHOW alloc]init];
popover = [[UIPopoverController alloc]
initWithContentViewController:popie];
popover.popoverContentSize = CGSizeMake(300, 700);
[popie release];
[popover presentPopoverFromBarButtonItem:THEBARBUTTONITEM permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
