Two questions:
I am trying to build a app that has a table view. I would like the user to click on a topic and then the next table view has a image on the left and text on the right. Does anyone know any sample code that would help me accomplish this?
Example:
iPad --> WiFi, and WiFi + 3G
iPhone --> AT&T, Verizon
Also is their a way to tag images in xCode? So in my table view I can only pull images with tag "x"?
Check out http://developer.apple.com/library/ios/#samplecode/TableViewSuite/Introduction/Intro.html for sample code on how to implement table views.
I don't understand your question about tagging. You can use [UIImage imageNamed:] to pull in images that are bundled in your app. Name them as you will.
See Dispelling the UIImage imageNamed: FUD for a discussion of this method.
First of all make a navigation based app. This gives you an app with a view controller in place with a table view on the screen.
Take a look at these for more info:
UITableViewController Class Reference
UITableViewCell Class Reference
In this last one take a look at initWithStyle:reuseIdentifier:, this will allow you to use the style you need, if you have default and add a picture to this cell it will show in the left side, pushing the text a little to the right.
For tagging an image you can simply do
image.tag = tagNumber;
For the cell image you can have like this:
image.tag = tagNumber;
cell.imageView.image = image;

I'm new to objective c. Want to implement EGOIMAGELOADER for my customised tableview, but as i have mutliple uiimageview and that has to be in their respective fix position so i have created uitablecell in xib and placed the uiimageview in the alignment i want it.
I went through the ego example but there the egoimageview is being used to create imageview dynamically.
I want to use my uiimageview with egoimageloader and not use egoimageview as i have fixed placement of imageviews in uitablecell.
I want to implement lazyloading and caching of images using egoimageview.
Can anyone help me with example or sample code to achieve above requirement.
As i'm using normal code for loading images in uiimageview for tablecell. So don't know what to include for code snippet.
I am fairly new to Objective-C so forgive my ignorance ahead of time =] Here is what I have so far:
The application is a tab bar style application
The view, as relevant to this post, contains several buttons that when clicked pull down different types of images
On click of the button an Array is populated with the data returned from the web service
A new view is displayed with a UIImageView inside of it
Now here is what I am hoping to get clarification on (or simply ideas)
As I said the application itself is a tab bar style app but I am having some trouble with the third view I've added. Currently when I click on a button the view loads correctly but it is loading inside of the Tab Bar view area. This isn't optimal and I would like for this new view to be displayed overtop of the Tab Bar thus taking up the entire area on the phone. I am opening this view from inside the View Controller that contains the button (which is a tab view) like this:
UIViewController * browsePictures = [[UIViewController alloc]initWithNibName:#"PictureGalleryViewController" bundle:[NSBundle mainBundle]];
[self.view addSubview:browsePictures.view];
On this third view I have a UIImageView (I am not sure this is the correct view for the app) that needs to be populated via the data that is returned from the web service. Returning binary data, as I found out, is very inefficient via JSON so I am returning URL's which means I will need to make a call out to the web for every image returned. I am ok with this I am just curious if there is a better way to do it.
The functionality I am trying to achieve with this third view is similar to the Camera Roll functionality of the iPhone. In this case when the user gestures to the left or the right it would move the current index of the array up or down one and load the next photo in the array. I am not sure how to implement this functionality.
I think that is all for now. Thanks!
I'm making an app and it has multiple button that when you press them it open a pop over view (using Storyboard.) The image is blank in IB (I set it that way) and my buttons are ment to populate the image view. This is the code I'm using:
[popoverImageView setImage:[UIImage imageNamed:#"telegraph.jpeg"]];
Steps (in order run)
Popover opens
Above code is run
Some notes:
The image is case matched.
The image is built-into the bundle
Anyone able to shed some light?
if you haven't read Apples View Controller Catalog for iOS you should read it.
I would check your popoverImageView's viewDidLoad/viewWillLoad and see if it is clearing your View before it presents itself.
Check your popoverImageView's properties they may not be linked properly
Enjoy using the storyboard I find it a pain for Popover's
Without any information regarding the the interface for your Popover and the implementation of the function where you call [popoverImageView setImage:[UIImage imageNamed:#"telegraph.jpeg"]]; and your setImage function i can't be sure of your exact problem
I want to replicate apple's default mail composer for my app. I don't want to use default mailcomposer because I'm having a lot of other things. Does anybody have solution for this? Main thing I want to implement is attachments. Like when you select a image and tap on email on photos app. The image preview is displayed in body part and also we can enter text and the cursor also detects the image when you press return or back. That functionality I want to achieve.
The TTMessageComposer in the Three20 library is a good start... it doesn't have attachment support but will save you time on the standard layout.
Three20 library
Check out this source code https://github.com/thermogl/TITokenFieldView, it's a custom UI class for token fields but there is a exact replica of Apple's mail UITextView. Heres a snippet from the source. All you have to do is create an normal text view and add it to your view.
// Creating the text view
messageView = [[UITextView alloc] initWithFrame:yourView.contentView.bounds];
// Adding it as a subview
[yourView.contentView addSubview:messageView];
// Set the frame so it resizes with the view.
[messageView setFrame:yourView.contentView.bounds];
I have a question about user interface in iOS, especially on iPad.
My app displays restaurant information from a search result. Not all fields are required, so some fields are empty. They could be phone numbers, ratings, menus, and etc.
So basically what I would like to do is to display views such as UILabel and UIButton in a layout format, but I don't want to display any views with empty string. So there should not be any empty space between views.
The way I do is if a field is not empty, I initiate its view and then display below the previously displayed view by keeping track of the current height a view should be displayed.
Although this works, I believe that the way it works seems tedious. Is there the best practice for displaying views with relative positions?
Thank you :)
I've created a library to solve just this problem: CSLinearLayoutView
You use it like this:
// create the linear layout view
CSLinearLayoutView *linearLayoutView = [[[CSLinearLayoutView alloc] initWithFrame:self.view.bounds] autorelease];
linearLayoutView.orientation = CSLinearLayoutViewOrientationVertical;
[self.view addSubview:linearLayoutView];
// create a layout item for the view you want to display and add it to the layout view
CSLinearLayoutItem *item = [CSLinearLayoutItem layoutItemForView:someView];
item.padding = CSLinearLayoutMakePadding(5.0, 10.0, 5.0, 10.0);
item.horizontalAlignment = CSLinearLayoutItemHorizontalAlignmentCenter;
item.fillMode = CSLinearLayoutItemFillModeNormal;
[linearLayoutView addItem:item];
// add more items
A way to do that is to use UITableView and follow what is said in this answer:
Auto adjust the UITableViewCell height depend on its contents in Objective-C
