Have a look at this image...
I want to design toolbar like this, Each UIBarButtonItem should be separated by a thin line. So I have inserted flexible space button in between each UIBarButtonItem (that helps me in aligning UIBarButtonItem while orientation changes), however if I set an image for that, its no more acting as flexible button, changes to normal UIBarbutton.
So I need an flexible space button with an image.. Any idea how to do it.
(OR)
How to design a UIToolbar like above... Any helps is really appreciated. Thanx
To set background image for UIBarbuttonItem
UIImage *faceImage = [UIImage imageNamed:#"facebook.png"];
UIButton *face = [UIButton buttonWithType:UIButtonTypeCustom];
face.bounds = CGRectMake( 0, 0, faceImage.size.width, faceImage.size.height );
[face setImage:faceImage forState:UIControlStateNormal];
UIBarButtonItem *faceBtn = [[UIBarButtonItem alloc] initWithCustomView:face];
I think this will help you..
UIImage* topImage = [UIImage imageNamed:#"TabBarGradient.png"];
// Create a new image context
UIGraphicsBeginImageContextWithOptions(CGSizeMake(width, topImage.size.height*2), NO, 0.0);
// Create a stretchable image for the top of the background and draw it
UIImage* stretchedTopImage = [topImage stretchableImageWithLeftCapWidth:0 topCapHeight:0];
[stretchedTopImage drawInRect:CGRectMake(0, 0, width, topImage.size.height)];
// Draw a solid black color for the bottom of the background
[[UIColor blackColor] set];
CGContextFillRect(UIGraphicsGetCurrentContext(), CGRectMake(0, topImage.size.height, width, topImage.size.height));
// Generate a new image
UIImage* resultImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return resultImage;

Could any one help me i want to add same image multiple times horizontally with same height and width. Important thing is i am creating image view dynamically i want to use same image view for all images! This is image i want to make horizontally like this but only one row needed like this.
You could achieve this by using stretchableImageWithLeftCapWidth:
UIImage *backgroundImage = [[UIImage imageNamed:#"SheetBackground.png"] stretchableImageWithLeftCapWidth:0.5 topCapHeight:0];
As per your request:
UIImage *backgroundImage = [[UIImage imageNamed:#"q4Ses.png"] stretchableImageWithLeftCapWidth:0.5 topCapHeight:0];
[_scro setBackgroundColor:[UIColor colorWithPatternImage:backgroundImage]];
And using your image:
The output is:
You can set this image on top of either UIScrollview, UIView and buttons. You do not need a for loop for that.
UPDATE:
The above code is for filling the entire background. If you wish to add only for one row then you have to create one UIView and set its colorWithPatternImage like below:
UIImage *backgroundImage = [[UIImage imageNamed:#"q4Ses.png"]
stretchableImageWithLeftCapWidth:1 topCapHeight:0];
UIView *v=[[UIView alloc]
initWithFrame:CGRectMake(0, 0, _scro.frame.size.width, 45)];
[v setBackgroundColor:[UIColor
colorWithPatternImage:backgroundImage]];
[_scro addSubview:v];
And the output:
Make a view of the height of image. But this view can have any width.
Then set your tile image in this view with following code.
UIImage *tiledImage = [UIImage imageNamed:#"myTiledImage.png"];
self.view.backgroundColor = [UIColor colorWithPatternImage:tiledImage];
This will get you the image tiled multiple times horizontally.
If the view spreads the image everywhere on screen then you'll have to add the following code to your view
self.view.clipToBounds = YES;
UIScrollView *myScrollView=[[UIScrollView alloc]initWithFrame:CGRectMake(0, 0, 320, 480)];
CGFloat scrollWidth = 0.f;
for (int i=0;i<10;i++)//i=10,put as many image number u want to display
{
imageView = [[UIImageView alloc] initWithFrame:
CGRectMake(scrollWidth, 0, 80, 60.f)];
imageView.image=[UIImage imageNamed:#"urimagename"];
imageView.tag=i;
[myScrollView addSubview:imageView];
scrollWidth += 100;
}
myScrollView.contentSize = CGSizeMake(scrollWidth, 100);
EDIT:
You can achieve this in one more way.
CodenameLambda1's answer is better than the above one.But still some changes needs to be done in the #CodenameLambda1's answer..as the SOP's requirement is to display it in scrollview.So instead of self.view use scrollview.
UIScrollView *vie=[[UIScrollView alloc]initWithFrame:CGRectMake(0, 0, 320, 60)];
UIImage *tiledImage = [UIImage imageNamed:#"login"];
vie.backgroundColor = [UIColor colorWithPatternImage:tiledImage];
vie.contentSize=CGSizeMake(1400,60);
vie.clipsToBounds = YES;
[self.view addSubview:vie];
I have a Background.png image with size of 200*100, and i set background image for a uiview as:
UIView view= UIView alloc] initWithFrame:CGRectMake(50, 100, 200, 100)];
view.backgroundColor = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:#"Background.png"]];
Now, I reset the frame UIView by:
[view setFrame:CGRectMake(50,100,400,200)];
I need to resize the background image in proportion of the uiview, but i have only one fixed size Background.png image. what shall i do.
Take your size accordingly
UIGraphicsBeginImageContext( newSize );
[image drawInRect:CGRectMake(0,0,newSize.width,newSize.height)];
UIImage* newImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
UIView view= UIView alloc] initWithFrame:CGRectMake(50, 100, 200, 100)];
view.backgroundColor = [[UIColor alloc] initWithPatternImage:newImage];
Else take an imageview and set contentMode, If u dont want to tile images
Depending on what your needs are, it might be simplest just to add a UIImageView as a subview of your view, and set its image, letting it handling the resizing for you. Otherwise, you'll probably have some complex resizing and drawing code to write.
I'm trying to make a button that basically mimics the buttons seen on the iphone's home screen - it has a picture placed vertically above some text, and both are part of the button and behave appropriately (dim, clickable, etc) when highlighted.
I've tried putting the picture or the text into its own frame but that doesn't work because whichever is in the new frame doesn't dim with the rest of the button.
Using the background image property doesn't work because I want the image above the text - the area behind the text should be transparent. I would REALLY prefer a programming solution instead of going in and editing all my pictures.
Create a subclass of UIView, and have a UIImageView and UILabel as subviews, and position them appropriately using code.
You'd then have the UIImageView and UILabel as properties so that you could access them, like this:
myCustomButton.imageView.image = [UIImage imageNamed:#"..."];
myCustomButton.textLabel.text = #"...";
Or you could probably find a 3rd Party custom UIView, on the internet on github or something.
Jonathan's idea is a good one, but if you're only doing it with a couple images it's not worth the trouble. You can create a UIImage and a UILabel and then place them inside a UIButton in interface builder.
Still, it's always a good idea to learn about powerful features like subclassing.
Good luck,

do this:
UIButton *btn_chat = [UIButton buttonWithType:UIButtonTypeCustom];
btn_chat.frame = CGRectMake(40, 50, 100, 30);//CGRectMake(20, 20, 200, 72);
UIImage *image = [UIImage imageNamed:#"chat.png"];
CGSize newSize = CGSizeMake(30, 30);
UIGraphicsBeginImageContextWithOptions(newSize, NO, 0.0);
[image drawInRect:CGRectMake(0, 0, newSize.width, newSize.height)];
UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
[btn_chat setImage:newImage forState:UIControlStateNormal];
btn_chat.imageEdgeInsets = UIEdgeInsetsMake(0, 10, 0, 0);
[btn_chat setTitle:#"Chat" forState:UIControlStateNormal];
btn_chat.titleEdgeInsets = UIEdgeInsetsMake(0, 20, 0, 0);
btn_chat.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft;
[btn_chat addTarget:self action:#selector(menuSelection:) forControlEvents:UIControlEventTouchUpInside];
[btn_chat setTag:1001];
[self.view addSubview:btn_chat];
and it's done :)
Create a new initially transparent bitmap drawing context, draw your image to the top and text to the bottom. Then make a new image from this drawing context, and use that new image for the button.
i have a image. in that image i need to draw text.
pls provide any links or sample code to try it out.
Thanks for any help
Just composite an extra view containing the text on top of the image. If you use a UILabel with [UIColor clearColor] for the background color and set opaque to false you will just see the text on top of the image and none of the image will be obscured.
If you want to get an image from the image in a view with the transparent view containing text on top of it, see this answer:
How to obtain a CGImageRef from the content of an UIView?
Something like this:
UIView* baseView = [[UIView alloc] initWithFrame:frameSize];
UIImage* imageToCaption = [UIImage imageNamed:#"myImage.jpg"];
UIImageView* imageToCaptionView = [[UIImageView alloc] initWithImage:imageToCaption];
imageToCaptionView.frame = frameSize;
[baseView addSubview:imageToCaptionView];
[imageToCaptionView release];
// do stuff with fonts to calculate the size of the label, center it in your image etc. etc.
CGRect labelFrame = ...
UILabel* myLabel = [[UILabel alloc] initWithFrame:labelFrame];
myLabel.backgroundColor = [UIColor clearColor];
myLabel.opaque = NO;
// set the color, font, text etc.
[baseView addSubView:myLabel];
[myLabel release];
Not compiled or complete but you get the idea. If you wanted to get the result as an image you would use do [baseView.layer renderInContext:context];
On the iPhone, how could I achieve the same tiled background effect?
For example, I have an pattern image which I want to repeat only horizontally. Would I have to go the route in -drawRect: by myself and loop over to draw the pattern, or is there a convenient method to do that?
You can set the backgroundColor of the UIView with a pattern using the following snippet:
UIImage *image = [UIImage imageNamed:#"pattern.png"];
myView.backgroundColor = [UIColor colorWithPatternImage:image];
The image will automatically be tiled for you to cover the area.

- (void)drawRect:(CGRect)rect
{
CGContextRef currentContext = UIGraphicsGetCurrentContext();
UIImage* img = [UIImage imageNamed:#"transparency.png"];
CGContextDrawTiledImage(currentContext, CGRectMake(0, 0, 12, 12), [img CGImage]);
}
In this example "transparency.png" is a 12x12 image.
