    - by anurag
    I have created 2 views named "FirstView" and "SecondView".SecondView's nib file has an UIImage view object as its IBOtlet.Now I am getting an UIImage object from some FirstViewController's method.Now I am setting the SecondViewController's imageView property with that image and then I am pushing my SecondView Controller's object in Navigation Controller.The SecondView gets loaded but that image is not shown in that view. The code is as follows:..... (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)img editingInfo:(NSDictionary *)editInfo { [[picker parentViewController] dismissModalViewControllerAnimated:YES]; SecondViewController *secondView=[[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:[NSBundle mainBundle]]; secondView.imageView.image=img; [self.navigationController pushViewController:secondView animated:YES]; }

  • Rebasing a core repo in git.

    - by b. e. hollenbeck
    I have a customized fork of CodeIgniter that I use as a standard baseline for several projects. Recently, I've made significant improvements in this repo that I want to use to update the client projects that use it. What I can't seem to figure out is how to pull in the changes to a client project. So I have: Baseline: A--B--C--D--E Client cloned @ C C'--D'--E' And I want to update the client repo to E from the Baseline project. I've tried rebase, and it has erased the files not present in the baseline project (views and such), and creates a bunch of conflicts that really don't need to be conflicts with things like the default HTML5 boilerplate that I use. Is there an option for rebase that I should be using? Is there a different way to approach it? Do I need a bunch of .gitignores for the content directories?

  • Switch back to previously selected tab after the activity is recreated

    - by ZelluX
    In my TabActivity the user may be asked to switch to browser activity for OAuth phase, and if the phase takes too much time, my activity will be killed. After the user switches back to my activity, its onCreate() method is invoked again and tabs are recreated. So I would like to know if there is any simple way to switch back to previous tab, and keep the tab as what it was. For example, one of the tab views contains a ViewSwitcher child, and I want to switch back to the switched view after recreating the activity.

  • Database suggestion

    - by superartsy
    I am working on an enterprise level product that is designed around SQL Express Database ( views,concurrent users,stored procedures,case,IF).Though we dont use any SQL Server advanced features, if the database size of 4Gb in express ends up being a limitation customers can move to advanced versions of SQL Server. However my problem is, SQL Express deployment is not easy and the installer size is huge. This is a major drawback for someone looking to try our product.You dont want end users to not buy a product becos the download is huge. Does anyone have any recommendations of a database that has a smaller footprint but all the features of Express and which can be migrated to express?

  • Qlikview joins that dosen't join on all matching column names

    - by Dev_Karl
    Hi! I'm new to Qlikview and looking for some answers regarding scripting. How can I create Qlickview joins that just join on a specific column (and not all that are having a matching name)? Let's say that I'm having the following tables: Employee Id | Person | DepartmentID | Flags 1000 , Bob , 2001 , 1000000 1001 , Sue , 2002 , 1100000 Department Id | Name | Flags 2001 , HR , 01101111 2001 , R&D , 1100000 What is the best way of joining those tables on the DepartmentID <- ID field? The data is provided by SQL selects. I'm thinking of writing SQL views using unique names would be one idea, but there must be a simpler way. Please advice Kind regards, Karl

  • best way to build iphone settings screen

    - by Christian Schlensker
    I'm building a settings screen for an iPhone app and it is supposed to resemble a grouped table view. Each "cell" should behave like a button. Most cells just have a image view, label view, and disclosure indicator. One will display a value in addition to a label. All of these buttons will present a new view when tapped. Now, how to implement this? I was considering just laying out a set of buttons with custom background images, or would it be best to just use a table view. If that's the case what should it be implemented. So far I've only used table views to display some kind of dynamic data in which each cell displayed the same basic detail view. I'm most curious to figure out how to setup cellForRowAtIndexPath. Would this contain some sort of switch statement to configure each cell individually, or is there an easier way to handle all this?

  • What is the correct way of handling a reloaded view after it was dismissed?

    - by favo
    Hi, I have the same problem as the guy here: http://stackoverflow.com/questions/2682844/uiimagepickercontroller-reloads-view-after-its-dismissed I have a UIView with a UIDatePicker within a Popover. When the Popover is dismissed and presented again, it sometimes resets the Picker in the view because hidden views are unloaded when a memory warning occurs. This is the part displaying the view: endCompareDateTimePicker.picker.maximumDate = [NSDate dateWithTimeIntervalSinceNow:0]; [endCompareDateTimePopover presentPopoverFromRect:sender.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES]; The picker (IBOutlet UIDatePicker) does not stay initiated. Adding a [endCompareDateTimePicker loadView] helped out and got me the picker initiated to set the correct date values before displaying the view. While this is working, I dont think this is the proper way doing this. What would be the correct way to handle this situation?

Not sure how to design all this and which views to use.

  • How to "flick" a UIImageView?

    - by Meltemi
    I've got some UIViews that I'd like the user to be able to "flick" across the screen. They're not scroll views. They simply contain a raster image (png). Can anyone point me to some sample code, etc to help get me started? Something a little more heavyweight than "MoveMe" out there that helps detect a "flick" (vs a "nudge" or a drag and drop) and then carries the view off in the direction of the "flick"? OpenGL probably overkill. If possible I'd like to stay w/in the realm of Core Graphics/Animation.

    - by Stefano Delendati
    I have a custom control that with a property that is a collection of custom object. This custom object hava a reference to some component/controls. When at design time I tray to add an item to the collection and select the object, VS tells me that the control is not serializable.

  • iOS subview widget hooked up to multiple controllers

    - by Allison A
    So, I want to create a reusable widget as a xib and subview that can appear on a set amount of specific screens. This widget will have three buttons, each with an Action. I want to be able to handle these actions on multiple viewcontrollers. So say ViewControllerA, ViewControllerD, and ViewControllerF can handle the three button events, each in their own way. I've created the nib file. How do I import it into the specific viewcontrollers, and then how do I wire up those events? EDIT: I know that I could potentially get outlets set up via a viewcontroller, but Apple states that UIViewController is for full-screen views only, and my widget is only taking up a small portion of the screen.

  • Where to add an observer to the NotificationCenter in a UITableViewController

    - by Saifis
    I want to send a notification from a UITableViewController-A to UITableViewController-B. I was adding the observer in the initwithCoder of the UITableViewController that is supposed to catch the notifications. The classes are correlated as folows RootViewController ===NavigationController-A =====UITableViewController-A ===NavigationController-B =====UITableViewController-B I need to add the observer before the views are actually loaded because notifications may be sent before the view is called. However I have been told that initializing in the initWithCoder method in a UIViewController is not advisable, and was told to add the observer in the AppDelegate. Are there any other suggestions for doing this?

  • animating adding/removing layers on iPhone

    - by magesteve
    On the iPhone, when you add a sub layer to a visible view's layer, using either -addSublayer: or -removeFromSuperlayer, shouldn't that sub layer appear or disappear in an animated manner (ie. fade in or fade out gradually)? My program animates using layers (not views). When I change a property of a layer like position or image content, then the change does animate (layer streaks around it's parent layer, the layer fades from the old image to the new image), so I obviously have the layers & view setup correctly. However, when I add or remove a sub layer, the change occurs instantly; there is no animation. Reading the references, it says that if the layer is visible, the sub layer should animate when adder or removed. What am I doing wrong? Has anyone had a similar problem, and was able to find a solution? Thank you, Steve Sheets

Actually I want to do <% form.fields_for delivery_date do |dd_f| %> but that fails as well.

  • Searching in Rails 3

    - by cbarton
    Here is the situation: I have the need to search for specifics or generals, much like expedia.com or your local library catalog search. In that there are fields that may or may not be filled out based on the individual need. It acts much like an "advanced search page". I have all of that code done for the models/controller and such and have it setup with a Searches controller along with matching model and views. The question that I have is there a way to cut down the amount of parameters posted to GET so that the url isn't search?search[:a]=""+search[:b]=""+search[:c]="x"... plus the unicode checkmark. I only want the filled out fields to be shown in the response link especially minus the checkmark. cbarton

  • Show a modal right after signup?

    - by user1494756
    When a user signup at my page I want them to be redirected to the root_path(this I have figured out how to do in the user controller). But then I want a modal to show in front of this page(and this should only happen the first time the user see this root/home page(like a flash message). Here is my create method in the user controller: def create @user = User.new(params[:user]) if @user.save sign_in @user redirect_to root_path else render 'new' end end The modal is placed in app/views/layouts/_modal.html.erb. Does anybody know how to make this happen? (Jepp, I am a newbie :)

  • Detect double-tap on UISlider?

    - by Randy
    I can detect single/double-taps in specific views with: NSSet *myTouches = [event touchesForView:mySpecificView.view]; but I want to detect a double-tap on the button of a slider and can't find any reference to it. Is there a replacement for "touchesForView:" where I can enter the name of my slider? usage: I have three sliders with their default value being directly in the center of the slider. Once the position of the slider has changed, I want a quick way to individually reset each slider to its default position. I currently have each slider's containing view set to respond to a double-tap, updating each slider. It works fine, but doesn't seem natural. ie.I can't double-tap on the slider itself because the slider intercepts the taps and doesn't pass them on to the surrounding view. thanks in advance
