Is there a way to tile an image in objective-j on a CPView?
something along the lines of:
[CPImage alloc] initWithPatternImage:#"Resources/grid.png" size:CGSizeMake(5.0, 5.0)]
Thanks guys ;)
Try this:
var image = [[CPImage alloc]
initWithContentsOfFile:"Resources/myimage.gif"
size:CGSizeMake(20, 20)];
var imageView = [[CPImageView alloc] initWithFrame:CGRectMake(0,0,500,500)];
[imageView setBackgroundColor:[CPColor colorWithPatternImage:image]];

So I've got a UISlider that I've been working on and I need it to have a custom image. I've got a nice #2x image which has a great amount of pixels and looks great when I add it to a UIImageView, but the moment I use the same image for a replacement for the UISlider thumb image, it pixelates the heck out of it and makes the thumb of the slider look like crap. Any thoughts on how to remedy this?
Here is some of my sample code.
slider = [[UISlider alloc] initWithFrame:CGRectMake(sliderOffset, 29.5, siderW, 50)];
[slider addTarget:self action:#selector(sliderAction) forControlEvents:UIControlEventValueChanged];
[slider setBackgroundColor:[UIColor clearColor];
slider.minimumValue = 0.0;
slider.maximumValue = 10000.0;
slider.continuous = YES;
slider.value = 3000.00;
[slider setThumbImage:[UIImage imageNamed:#"Slider#2x.png"] forState:UIControlStateNormal];
[slider setThumbImage:[UIImage imageNamed:#"Slider#2x.png"] forState:UIControlStateHighlighted];
Thanks in advance!
Here's how I solved it:
1) Subclassed UISlider
2) Created a clear image and set the slider thumb to that clear image.
[self setThumbImage:[UIImage imageNamed:#"ClearImageForOverride.png"] forState:UIControlStateNormal];
[self setThumbImage:[UIImage imageNamed:#"ClearImageForOverride.png"] forState:UIControlStateHighlighted];
3) Created a UIImageView and made that follow the center of the thumb.
float imageWH = PassedInHeightWidthFromSubClass;
imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 1, imageWH, imageWH)];
imageView.image = [UIImage imageNamed:#"NewThumbImage"];
[self addSubview:imageView];
[self bringSubviewToFront:imageView];
imageView.center = CGPointMake(thumbRect.origin.x + self.frame.origin.x + localImageViewCenter, self.frame.origin.y - sliderImageViewYOffset);
[self addTarget:self action:#selector(sliderValueChanged) forControlEvents:UIControlEventValueChanged];
4) Then when the sider value changes I tell the imageView where it's center should be.
-(void)sliderValueChanged {
CGRect trackRect = [self trackRectForBounds:self.bounds];
CGRect thumbRect = [self thumbRectForBounds:self.bounds trackRect:trackRect value:self.value];
imageView.center = CGPointMake(thumbRect.origin.x + self.frame.origin.x + localImageViewCenter, self.frame.origin.y - sliderImageViewYOffset);
}
Essentially with this you can have any size of image for the slider knob which looks great and works flawlessly as the knob.
I have set a UINavigationBar background image to an image with a height of 68px as opposed to the default 44px. Now the image is shown fine, but the content in the UINavigationController is overlapped in the first (68-44)px = 12px by the header image.
How do I fix this? I have tried setting the frame of the UINavigationBar without luck.
Thanks, Caspar.
This is my code (AppDelegate.m):
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:self.frontTableViewController];
UINavigationBar *navBar = navigationController.navigationBar;
[navBar setBackgroundImage:[UIImage imageNamed:#"header"] forBarMetrics:UIBarMetricsDefault];
self.window.rootViewController = navigationController;
try setting the image for the navigationbar this way
self.navigationItem.titleView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"myNavBarImage.png"]];

How can i take an image and stretch it to fill the screen on my UIView (320/460)
I am loading and placing it, however as you can see, some scaling is needed.
Thank you!
CGRect gameArea = CGRectMake(0, 0, 320, 460);
UIImage *backgroundImage = [UIImage imageNamed:#"green_background.jpg"];
UIImageView *myImageView = [[UIImageView alloc] initWithImage:backgroundImage];
[myImageView setContentMode:UIViewContentModeScaleToFill];
UIView *topView = [[UIView alloc] initWithFrame:gameArea];
[topView addSubview:myImageView];
[[self view] addSubview:topView];
Like I said in my comments above to Shamsiddin's post, the UIImageView needs a size to know where to stretch to. Here I'm using the same size of the UIView. I've added another answer because the code to UIView is missing. So here's the complete code.
// Area of the UIView and UIImageView
CGRect gameArea = CGRectMake(0, 0, 320, 460);
// Create UIImageView with Image
UIImage *backgroundImage = [UIImage imageNamed:#"green_background.jpg"];
UIImageView *myImageView = [[UIImageView alloc] initWithFrame:gameArea];
[myImageView setImage:[backgroundImage stretchableImageWithLeftCapWidth:3 topCapHeight:3]];
[myImageView setUserInteractionEnabled:YES];
// Create UIView and insert subview
UIView *topView = [[UIView alloc] initWithFrame:gameArea];
[topView addSubview:myImageView];
[[self view] addSubview:topView];
CGRect gameArea = CGRectMake(0, 0, 320, 460);
UIImage *backgroundImage = [UIImage imageNamed:#"green_background.jpg"];
UIImageView *myImageView = [[UIImageView alloc] initWithFrame:gameArea];
[myImageView setImage:[backgroundImage stretchableImageWithLeftCapWidth:3 topCapHeight:3]];
[myImageView setUserInteractionEnabled:YES];
[self.view addSubview:myImageView];
try
UIView *view;
view.ContentMode = UIViewContentModeScaleToFill;
I just did this in my own iOS5 app, i needed to dynamically set the background image and scale it. Imagine you are doing this in - (void)viewWillAppear:(BOOL) animated
UIImageView *imageview = [[UIImageView alloc] initWithFrame:self.view.frame];
[imageview setContentMode:UIViewContentModeScaleAspectFill];
[imageview setImage:[UIImage imageNamed:#"Background.png"]];
[self.view addSubview:imageview];
[self.view sendSubviewToBack:imageview];
So we create the view, set it's scaling mode, add the bg image, set it as the subview in the main view and then push it to the back so it does not occupy any other subviews.
Please accept this answer.
hi am doing an iphone twitter app with json and i am wondering if it is possible to set the
cell.accessoryType to a image in UITableView? or possible move the image to the right hand side...any clues?
Sure. Just use the accessoryView property of UITableViewCell and assign a UIImageView:
UIImage *image = [UIImage imageNamed:#"fileNameOfYourImage.jpg"]; //or wherever you take your image from
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
cell.accessoryView = imageView;
[imageView release];
No need to use imageview, just provide this for simple arrow.
cell.accessoryType=UITableViewCellAccessoryDisclosureIndicator;
i have an uibarbuttonitem, but i was initialize it using initwithcustomview. I want to change it backgrounds using an image, but i dont know how to do. I was using setBackground method, like this
NSArray *segmentText = [segmentTextMutable copy];
UIImage *image = [[[UIImage alloc] init] autorelease];
image = [UIImage imageNamed:#"bunga.jpg"];
_docSegmentedControl = [[UISegmentedControl alloc] initWithItems:segmentText];
_docSegmentedControl.autoresizingMask = UIViewAutoresizingFlexibleHeight;
_docSegmentedControl.segmentedControlStyle = UISegmentedControlStyleBezeled;
[_docSegmentedControl addTarget:self action:#selector(docSegmentAction:) forControlEvents:UIControlEventValueChanged];
[_docSegmentedControl setBackgroundColor:[UIColor colorWithPatternImage:image]];
but the uibarbuttonitem still not show the image, it's just change the segmented control background, not the barbutton.
Can somebody help me?
Perhaps you want to change the tint-color (#property(nonatomic, retain) UIColor *tintColor) because UISegmentedControl has no background-color (just because it inherits it from UIView does not mean it uses it though)
