i know this is to much silly question but i dont remember how to do this .
i want to make selected image when in table select image.
i want to add image in call and diffrent image in selection.
how can i do this ?
If you want to set the image as selected state when clicks the table view row. Use this code,
CGRect a=CGRectMake(0, 0, 300, 100);
UIImageView *bImg=[[UIImageView alloc] initWithFrame:a];
bImg.image=[UIImage imageNamed:#"YourBackGround.png"];
[bImg setContentMode:UIViewContentModeScaleToFill];
cell.selectedBackgroundView=bImg;
[bImg release];
Not sure if I could parse your question correctly, is this what you need?
UITableViewCell *cell;
cell.imageView.highlightedImage = theHighlightedStateImage;

I am new to Xcode, and I am currently building my first app. I've searched long and hard to try and find the proper tutorial but I can't find one. I am looking for a way to be able to insert a custom background in my UITableViewController. I can change the color, but that is it. What I am looking to do is set my PNG image behind the static cells I've created, and drop the opacity on those cells so the custom image comes through. Can someone please give me a way to do this either through the IB (storyboard) or through the coding. Much appreciated!! Thanks in advance!
I think the easier and correct way is to:
[tableView setBackgroundView:[[UIImageView alloc] initWithImage:[UIImage imageNamed:#"yourimage.png"]]];
You can include this code in viewDidLoad to make it work.
for cell's background :, do this in willDisplayCell:atIndexPath: method
UIImageView *cellImageView = [[UIImageView alloc] initWithImage:[UIImageimageNamed:#"image.png"]]];
CGRect Frame = cell.backgroundView.bounds;
cellImageView.frame = newFrame;
[cell.backgroundView addSubview:cellImageView];
for tableview background , do this in viewDidLoad: method
self.tableView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:#"BackgroundPattern.png"]];
UIImageView *ivwCellBackground=[[UIImageView alloc]init];
[ivwCellBackground setImage:[UIImage imageNamed:CELL_BACKGROUNGIMAGE]];
cell.backgroundColor=[UIColor clearColor];
[cell setBackgroundView:ivwCellBackground];
[ivwCellBackground release];
ivwCellBackground=nil;
I have an asychronous image loader which loads images (JImage) in a UIImageview. I want to display these in a tablecell. Obviously i cant set cell.imageView.image because i dont have an image, i just have a view.
How do i set the UIImageview to the tablecell? cell.backgroundView works though, but that paints over the whole cell.
The JImage code is:
NSURL *theUrl=[NSURL URLWithString:imageURL];
JImage *photoImage=[[JImage alloc] init];
[photoImage initWithImageAtURL:theUrl];
[photoImage setContentMode:UIViewContentModeRedraw];
[photoImage setFrame:CGRectMake(0.0f, 0.0f, 40.0f, 65.0f)];
cell.backgroundView = photoImage;
[photoImage release];
which in the JImage.m:
- (void)connectionDidFinishLoading:(NSURLConnection*)theConnection
{
[self setImage:[UIImage imageWithData: data]];
}
use this code and set frame according to your need.
UIImage *imagearrow = [UIImage imageNamed:#"arrow.png"];
UIImageView *imgarrow=[[UIImageView alloc] initWithFrame:CGRectMake(290, 25, 7, 15)];
imgarrow.image =imagearrow;
[cell addSubview:imgarrow];
[imagearrow release];
You don't need to use JImage if all you want to do is load the image asynchronously. One easy way to do this is with GCD and blocks, like so: https://github.com/ChrisTec/iPhone-Book-CodeSamples/blob/master/Chapter%2013/RealEstateViewer%2013.2.5/RealEstateViewer/ImageTableViewController.m
Here's a sample chapter of the book Objective-C Fundamentals which I've co-authored that explains this code in depth: http://www.manning.com/fairbairn/OCF_sample_ch13.pdf
To sum it up: When the cell is requested, you look if you already have downloaded the image. If you have, you display it. If not, you display a spinner and start an async GCD block that will fetch the image. One that block is done, it will run another block on the main thread that switches the spinner out for the image. That's all.
I think you should take a different approach to this. Instead of putting your JImage in the cell, hold it somewhere else in the view controller, an NSArray is usually convenient. Then populate the cells with either placeholder images or just leave them empty.
So let's say you have an array with all the JImages that are loading, when the JImage in the position x of the array finishes loading, you reload that specific cell as it follows:
NSIndexPath indexPath = [NSIndexPath indexPathForRow:x inSection:0];
[self.tableView reloadRowsAtIndexPaths:x withRowAnimation:NO];
And in your cellForRow:AtIndexPath you just have to take the image from the JImage object held in the array.
I hope this helps you
I have set imageView's frame in table using the following code.
cell.imageView.image = [UIImage imageWithContentsOfFile:[[users objectAtIndex:indexPath.row] valueForKey:#"ImagePath"]];
[cell.imageView setFrame:CGRectMake(5, 5, 10, 10)];
But image is displayed from the corner of the cell.
It does not changes the position or size.
what should I do ?
You will not be able to change the cells imageView frame. Your best option would be to create a custom cell.
You can change the frame of the cell by creating a subclass of UITableViewCell and overriding the layoutSubviews method.
In your subclass implementation of layoutSubviews, call super's implementation first and then modify the frame of imageView.
You can add your desired imageview as a subview to the cell
UIImageView *imageView = [[UIImageView alloc] init];
imageView.image = [UIImage imageWithContentsOfFile:[[users objectAtIndex:indexPath.row] valueForKey:#"ImagePath"]];
[imageView setFrame:CGRectMake(5, 5, 10, 10)];
[cell addSubview:imageView];
You can create custom table view cells and position the elements where you want them to be.
Its also helpful as you will have control on how similar you want your UI to be be to the requirements.
You can do it in interface builder or in code. Also there are loads of examples as this is most common approach in iphone app development (Having a custom table view cell) and you can use the delegates to populate the table view and it works like a charm.
I need to display one or more different images from array in one cell of UITableView like grid view without using any API for example three20 etc . Please give solution for my question.
This will put an image at the beginning of the cell:
[cell.imageView setImage:[UIImage imageNamed:#"whatever.png"]];
This image you can place anywhere on the cell by altering the frame:
UIImage *accessoryImage = [UIImage imageNamed:#"whatever.png"];
UIImageView *accImageView = [[UIImageView alloc] initWithImage:accessoryImage];
accImageView.userInteractionEnabled = YES;
[accImageView setFrame:CGRectMake(self.tableView.frame.size.width-70, 5, 28.0, 28.0)];
[cell.contentView addSubview:accImageView];
i have the different image with the different size too, i want to put it in cell.imageView.image in every cell, but i want make same size in every cell although the image have the different size, i write this on my code :
UIImage *image = [UIImage imageNamed:imageName];
cell.imageView.image = image;
cell.imageView.layer.masksToBounds = YES;
cell.imageView.layer.cornerRadius = 5.0;
float sw=image.size.width/cell.imageView.image.size.width;
float sh=image.size.height/cell.imageView.image.size.height;
cell.imageView.transform=CGAffineTransformMakeScale(sw, sh);
but it doesn't work, i'am sure that's right..
any body can help me.??
I just ran into this same problem. I wanted the photos to be 65 x 65, but they were filling in the size of the UITableViewCell instead. I resolved it by creating the UIImageView programmatically and adding it as a subview to the UITableViewCell. For example:
UIImageView *imageView = [[UIImageView alloc] initWithImage:photo];
imageView.frame = CGRectMake(6.5, 6.5, 65., 65.);
[cell addSubview:imageView];
Edit for clarity: This problem was occurring when I tried to create the UIImageView in Interface Builder. I took it out of Interface Builder and added it programmatically instead.
In case anybody else runs into this with custom cells: it appears that if your custom cell has an outlet named imageView, it will be treated like the image view in a basic-style cell, i.e. the image view's size will be adjusted. Simply picking another name avoids this behavior.
If your cell is a built in cell, it is supposed that the cell will resize all the images to a fixed, default size. Can you post an screenshot of your application as well?
I just saw your question. I faced the same problem, and the code worked for me is following:
cell.imageView.frame = CGRectMake(0, 0, 50, 50);
Hope, it will solve your problem
