I have 2 questions;
1.) i have added a button to a cell, and upon clicking that button i need to delete that cell (i don't want to use the edit feature of the cell to do this). I don't think i should show you the code how i added the button to the cell (i think it has nothing to do with this). Can someone help me delete the cell from the table. My button even is as follows;
-(void)deleteCellFromTable:(id)sender{
}
2.) How do i add Images or photots in the simulator ?
One way I can think of is to delete the data from the array you are loading into the TableView and reloading the tableview's data to achieve this.
you open the simulator and drag and drop images into it. it will be added automatically
You will want to call deleteRowsAtIndexPaths:withRowAnimation: on your tableview and pass an array with the row's index as well as the animation you want to occur.
I assume you mean selecting an image from the UIImagePickerController? You can save an image from Safari and it will be saved to your media library (viewable from Photos.app). If you have a file on disk that you want to add you can drag and drop it to the simulator and the simulator will open the image in Safari, you can then save it from there as normal (hold down on the image till the option comes up)
One siplese way is:
Just add an image to the view already existed in cell instead of data.
cell.imageView.image = [UIImage imagenamed:urImage];

Please help me to create drop down box using iphone. I tried in pickerview with textfield but not worked as my requirement can u suggest the url for to solve this problem. The data should come from xml and as a select option in html.
The easiest way is to use a UITableView with the options, which upon selecting a cell, returns the value of that cell to whatever control that has the select.
For the select you can use a button with a custom image for example, and show a table using presentModelViewController.
When the TableView shows and a selection is made, you store the selected value and dismiss the tableView using dismissModalViewController.
I had the same problem where the Picker just did not fit my requirements and used the tableView solution.

Thank you in advance.
Add a UIImageView to the view and then do:
myUIImageView.image = [UIImage imageNamed:#"anImageInMyBundle"];
Now, if you want to have a bunch of images and go through them systematically, you have a few options. This is going to depend on what your app actually does.
If you're displaying local images that are in your bundle, you can just create an NSArray (mutable or immutable - per the situation) and add all your UIImages to it at run time.
If your app downloads data from the web, you're probably going to start making network calls in a secondary thread that downloads and sets the next image. Give us a better idea of what your app does, and we might be able to provide more specific code/examples.
hi i am a new iphone programmer
i am creating a imagedisplay type application where i have to display images on a view and by presssing a next button a new image should appear on same view (i am using database)...
therefore i need to reload my current view again and again...each time when i click that button....
i tried some suggesion which are given on this website but not satisfied because many of them are based on timer...
please help.....
May be I have missed something in your question. But why you need to reload the entire view? You are using an UIImageView to display your image, right? And you are not showing any kind of scroll, but only a next button, right? Then why don't you just set the image property of UIImageView when the button is tapped.
// in button handler
myImageView.image = [UIImage imageNamed:#"new_image.png"];
Perhaps you could use a paged UIScrollView with three uIImageViews and always have the previous, current and next image loaded. This way when the user hits next, it scrolls animated to the next image. When page 3 is loaded, it programmatically sets the second image view as the desired next image, sets the image you came from on the first image view, and sets the scroll view non-animated to page two and loads the next image in the third image view.
Sounds complicated but basically you are giving the appearance of an infinite scroller but only pulling one image at a time except for initial load of three.
You could try looking at the "PageControl" Example Project in the XCode Documentation. It should give you a good starting point.
I'm developing a notebook based application. it consists of notes and images also.
I'm unable to find the best way of coding to add images and text together. it is also editable, so I'm getting confused whether to take scroll-view or text view. If I take scroll-view there is no editable option. if I take text view we can't change frames of the image .
Solved as follows. Taken Scrollview, in that managing size of the textview & inserting image with Specified size. Like textview,image,tetxview, image and goes on...
Thanks for all your support to solve the issue.
You can use a TableView. Put the image in a custom cell with the view as an ImageView.
Put a UITextField as the second cell for text note.
Alternatively, you can use a view swap method, where the text view is on the back of the image by clicking on an "Info" button to use the Flip transition and show the note. The facebook app does this now for "Comments" on photos.
I'm building an app (not necessarily a twitter client) and I'm trying to figure out how developers create the buttons above and below a table view where a user presses them to either reload newer data or reload older data into a table view. Does anyone know of any tutorials out there that does this or know of an easy way?
If you want fixed buttons, you can just make your table view not use the full screen and add the buttons in the space. If you want the buttons to scroll with the table view, you can add a header or footer view to the table and put your buttons inside that.
Check the Three20 project. I believe there's a tableview there that does that.
It's actually not that hard to add inline buttons to a tableview. First you check and see if there's actually more data to show. If so, you want to add 1 to the number of rows returned from the datasource. When asked to draw that last row you return a cell that contains "Press for more" caption as well as a hidden spinner instead of the standard cell that shows your normal data.
If the user presses that last button the table view handler turns on the spinner then fires off a network event. Once the network request completes the data is processed and added to the same tableview datasource that was used to draw the first table.
Now all you have to do is tell the tableview to reload itself and the new data will show up. If you want to limit the amount of data shown you can prune out N number of items from the head of the datasource before redrawing so the memory-use stays manageable.
