I'm using UIRefreshControl to refresh data.
When I scroll upper, it refreshes data.
But I want to set refreshing view to my own custom image.
What I'm looking for is that purpule position
I want to set my own image at that section.
I don't know how that position is called so I couldn't search properly.
Just create an instance of UIImageview and add an image as a subview to the refresh controller.
UIImageView *imgview= [[UIImageView alloc] initWithImage:[UIImage imageNamed: #"refreshControl.png"]];
[self.refreshControl insertSubview:imgview atIndex:0];

Im a beginner in programing iOS, so I have 2 questions:
1- I have a UIViewcontroller which load a few uiview and user is able to move them via touch. Now I want to put an image background in this way:
UIImageView *backgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"board.png"]];
[self.view addSubview:backgroundView];
But the image covers over all uivews!!
2- As I said, I move my uiviews by touch and when they have collided in the end touch they both goes in a folder, and a folder is created. So I want to know how I can make that a special image shows on the created folder ??
if (view != toMove && CGRectContainsPoint(view.frame,toMove.center)) {
viewToBefolder = view;
}
You can add your background view first, and then the rest of the views you add will be on top, or just do this:
[self.view sendSubviewToBack:backgroundView];
If your image view is covering the the background, you should be setting the size and position of the image view, or setting the constraints so that it is added at the size and position that you want.
Set your imageview into the main window.
UIImageView *backgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"background.png"]];
[self.window addSubview:backgroundView];
[self.window sendSubviewToBack:backgroundView];
Then set all your view controller view clear color. so, By default it's always display background image view into the all view.
I'm currently making a photo decoration app. The *holderView is the sticker that has been chosen by user. Whenever I try to load a photo from photo library or take a photo and then load back to this page, additional *holderView added programmatically, which is the sticker that I've previously chosen before taking a photo, duplicated sticker appears after that, which is not what I want it to be.
How should I write the code for not letting this happen?
Thanks a lot.
- (void)viewWillAppear:(BOOL)animated {
UIView *holderView = [[UIView alloc] initWithFrame:CGRectMake(0, 50, _imagePicker.selectedImage.size.width, _imagePicker.selectedImage.size.height)];
UIImageView *imageView = [[UIImageView alloc] initWithFrame:[holderView frame]];
[imageView setImage:_imagePicker.selectedImage];
[holderView addSubview:imageView];
...
}
Your problem seems to be that your using the viewWillAppear method instead of the viewDidLoad. This will cause multiple "imageViews" because your adding a new one every time you hide then show the viewController it's presented in. what you want to do is move the creation of the imageView (if there really is suppose to only be 1) to the viewDidLoad method and make that imageView accessible to the entire class, then in the viewWillApear simply change the image inside the imageView to the newly selected one.
I have a XIB file with UIControl and UIScrollView elements inside of it. I would like to add a background image to the view. I tried adding an ImageView in IB but I could not get it to be present as a background and it obscured the control elements. Sending a sendViewBack message doesn't seem to do anything either.
When I create a UIImageView programmatically, it doesn't show up.
Below is the code I attempted:
Programmatic Creation
UIImage *imageBackground = [UIImage imageWithContentsOfFile:#"globalbackground"];
UIImageView *backgroundView = [[UIImageView alloc] initWithImage:imageBackground];
[[self view] addSubview:backgroundView];
[[self view] sendSubviewToBack:backgroundView];
Dealing with the NIB file
[[self view] sendSubviewToBack:background];
where background is an IBOutlet declared in the header file and connected to the NIB's image view in IB.
Is there a step I'm missing here?
Set the frame and dont use sendSubviewToBack:. If you are working with UIImageViews you have to use [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"imageName.png"]];
UIImageView *backgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"imageBackground"]];
backgroundView.frame = self.view.bounds;
[[self view] addSubview:backgroundView];
hope this was the deal.
Don't add the image view as a subview of the scroll view, it needs to be a separate view at the top level of the hierarchy, then sent to the back of the Z-order.
You will need to set the background of your scroll view to [UIColor clearColor], and ensure that the scroll view is not marked as opaque. You can do this in code or in interface builder.
Don't use imageWithContentsOfFile and then just pass it a filename with no extension (I'm assuming .png) - this is probably returning nil. Use imageNamed: instead (you don't supply an extension in that case, iOS4 and above)
Depending on the nature of your image, you can also generate a colour with it and use that as the background colour of your scroll view. I'm assuming self.view is the scroll view:
self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:#"globalBackground"]];
how can i set the background color of a grouped table view to clear color so that is get the image of the underlying Image View.
i tried to set the view color to clear view in the xib
it works fine in case of a normal table view
but doesnt work for a grouped table view
i also tried it programmatically but in vain
is there any work around
Check this code for clear the background color of grouped table view..
UIView *backView = [[UIView alloc] init];
[backView setBackgroundColor:[UIColor clearColor]];
[yourTableView setBackgroundView:backView];
Thanks..
I designed a very simple interface for an ipad device: UIView + a navigation bar.
Then after the view is load, it will download an image from a location and use the following method to display it:
-(void)connectionDidFinishLoading:(NSURLConnection *)connection{
UIImage* testImg = [UIImage imageWithData:_networkData];
UIImageView* testView = [[UIImageView alloc] initWithImage:testImg];
[_view addSubview:testView];
[testView release];
}
The problem is now the new UIImage occupies the whole visible area of the Ipad.
I wonder how can I fix this issue? I suppose I have to find out the frame of the display area in the original view, and then assign it to the UIImageView instance?
initWithImage will automatically adjust the frame to match the size of the image you're passing in. To tell the UIImageView to take the same size as its parent view you could just add the following line before you add the subview:
testView.frame = _view.bounds
...we use bounds rather than frame because the superview may have an offset that we don't want the image view to have.
