I have a toolBarItem which calls a save action on a database. I would really much like to change the image of the item (a cabinet) dynamically so that a drawer opens, a label is animated "inside" and then it closes. Very much like the trash item on the mail app animation.
I know how to make a UIView pop-up by scaling it up and down on an animation on a given times given in an array (together with an array of CT scale), so I'm guessing it could be done more or less the same way.
Does anyone know about an example of who to accomplish that?. Back on xcode 4.1 i was able to highlight the button while the label was moving, but I cannot do that anymore (somehow I did add a normal button on the toolbarItem, which I cannot do anymore).
Thanks in advance!
well, if somebody is having the same issue here is how it can be done:
- (IBAction)barButtonAction:(UIBarButtonItem *)sender {
NSArray *frameArray=[NSArray arrayWithObjects:[UIImage imageNamed:#"01-refresh.png"], [UIImage imageNamed:#"02-redo.png"], [UIImage imageNamed:#"03-loopback.png"], [UIImage imageNamed:#"03-loopback.png"],[UIImage imageNamed:#"03-loopback.png"],[UIImage imageNamed:#"03-loopback.png"],[UIImage imageNamed:#"03-loopback.png"],[UIImage imageNamed:#"03-loopback.png"], nil];
self.button.image=[UIImage animatedImageWithImages:frameArray duration:10.0];
}

I am new to Xcode and objective C so the problem I have hit may be a simple one but I haven't been able to find an answer yet so thanks for any help you can give.
I am trying to write a simple app that takes a picture from the camera and displays it in a UIImageView. This all works fine if the UIImageView control is just placed in the UIView control (using the interface builder). The code I use to set the image to the control is
[self.imageViewOSFCorner setImage:image];
However I need to display several images an wanted the user to be able to scroll up and down the page. So I created a UIScrollView in the interface builder that is the size I need and placed all the controls in that. Then in the viewDidLoad method I placed the following code to display the UIScrollView
self.scrollView.contentSize = self.scrollView.frame.size;
self.scrollView.frame = self.view.frame;
[self.view addSubview:self.scrollView];
This works in that you can now scroll the page and see all of the UIImageView controls, and when I press the button it launches the camera, but now after taking the picture it doesn't display the image into the UIImageView. If I take the UIScrollView away it works again (but obviously doesn't scroll) - I am guessing I am doing something silly, is there a function I need to call to update the UIScrollView?
As an aside I originally tried to use the code
self.imageViewOSFCorner.image = image;
to display the image but this wouldn't display the image and had to use
[self.imageViewOSFCorner setImage:image];
can someone tell me why the first method didn't work?
Thanks
Will
May be useful：
self.scrollView.frame = CGRectMake(0, 0, self.view.frame.size.width*num,view.frame.size.hight );
num is your number of all image
Ok it is working now, I must have done something stupid when creating the controls into the UIScrollView since I have started from scratch again in the interface builder and now it all works.
hi i have a uiscrollview that i have 4 images with buttons laid out vertically in storyboard, i have paging enabled but it skips most of the images and snaps onto the last one.Is there a way to make it stop on each fullscreen image without loading a bunch of uiviews?
here is the code i already have its pretty basic.
.h
IBOutlet UIScrollView *scroller2;
}
#property (nonatomic, strong) IBOutlet UIScrollView *scroller2;
#end
.m
#synthesize scroller2;
[scroller2 setContentSize:CGSizeMake(320, 3543) ];
scroller2.pagingEnabled = YES;
I dont have enough rep to post a comment so an answer will have to suffice.
I was having problems replicaing your problem so I was wondering please if you could post the size of your imageViews inside the scrollView. Also are you loading the images from the web somewhere or are they just local images?
The way paging enabled works is that it assumes that every "page" or imageview and picture in your case is right next to each other with no gaps. It calculates the pages simply by adding whatever the screen size of the device is and snapping to that next point. When you say its skipping some photos do you mean that it is snapping to halfway down a photo in some cases or just skipping right to the end?
If you try and lay everything out right underneath each other in blocks of 480px then paging enabled should work for you.
Hope this is of some help, let me know how you get on
Ok, so I've created an image in Photoshop that will align with the buttons on my app, and now I'd like to make it the background image of my window so that the characters on the image will correspond to the keys on my app (a small calculator demo app I've been working on)
Basically, instead of giving buttons Text like 1,2,3,4, etc. I've made a 3x3 map with numbers of a different font just because it will look pretty
What I'm having difficulty with now is that I can't seem to make the image the background of my window.
I created an NSImageView and I dragged the image file onto it, so I can see it now, but I can't make it the background.
Do I need to subclass the NSImageView or is there some simple method?
I'm using XCode 4, btw
Thanks!
I think you should be able to do something like:
[window setBackgroundColor:[NSColor colorWithPatternImage:[NSImage imageNamed:#"myImage.png"]]];
This is something that a layer-backed window would be good at:
[[window contentView] setWantsLayer:YES];
[[window contentView] layer].contents = myImage;
I think you stand a better chance of getting this to resize sensibly (assuming you need to) than with a pattern color.
Just to give you more options -- you should be able to [window setContentView:myImageView]. In the .xib file you'd want to add your buttons etc. as subviews of the image view.
I don't necessarily recommend this approach, but it's something to think about.
How can I get the on-screen location of a button in a toolbar? That is getting the rectangle frame of an NSToolbarItem? The [NSToolbarItem view] method seems to always return nil whenever the toolbar item is only a simple action button and thus I couldn't use the normal NSView methods to pinpoint the toolbar button's on-screen position.
Background
I'm trying to use Matt Gemmell's MAAttachedWindow component to point to a specific toolbar button. The component requires an NSPoint object to "point" the user to a location on the screen.
Thanks in advance.
I happened to have the same kind of problem. Although I wouldn't say I solved it, I found a way that at least works for my scenario...
In my ToolbarItem action I fetch the current mouse location - it proved to be sufficient in this case. An example implementation might look like this:
- (IBAction)showOverlay:(id)sender {
NSPoint clickedPoint = [self.window mouseLocationOutsideOfEventStream];
self.overlayController = [[MyOverlayController alloc] initAtPoint:clickedPoint];
}
I'm working on an iPad application and I'm using UIPopoverControllers. I'm at the part where the app needs to be branded and styled and i'm wondering how to change the color / tint of the UIPopoverController? Standard is dark blue but it needs to be another color..
is this possible?
Greets, Thomas
This is possible starting in iOS 5.0 by subclassing the abstract class UIPopoverBackgroundView and assigning your subclass to the popoverBackgroundViewClass property on your UIPopoverController instance. Unfortunately there is no tintColor property as the popover needs to use images for it's arrow and border in order to achieve smooth animations during dynamic resizing. You can learn more about how to customize the appearance of a UIPopoverController in the UIPopoverBackgroundView Class Reference
It's impossible for now.
It's what I call the "Box in a Box" model. You get control of the box inside of the box (the UIViewController inside of the UIPopoverController), but you have very limited control over the actual popover itself. Outside of the arrow direction and the size, you can't change much else. There are also options for a modal effect popover, which dims everything else when it shows up, but I haven't tried to get it working.
I'm sure you've noticed there is no UIPopover class by now.
The answer you want to hear:
If you really want to style one that bad, just write your own. It's really not that hard.
The link you want to click:
Cocoacontrols is an index of iOS and OSX components available on GitHub, they have some popover stuff.
iOS 7 introduces backgroundColor property of UIPopoverController which affects/includes the navigation background color as well as arrows of popover.
#property (nonatomic, copy) UIColor *backgroundColor NS_AVAILABLE_IOS(7_0);
Usage example:
if ([self.popoverVC respondsToSelector:#selector(setBackgroundColor:)]) { // Check to avoid app crash prior to iOS 7
self.popoverVC.backgroundColor = [UIColor greenColor]; // [UIColor colorWithPatternImage:#"..."] doesn't reflect the color on simulator but on device it works!
}
Note - As of now (iOS 7.0.3), in some cases (like set color using colorWithPatternImage:), the simulator (and even some devices) doesn't honor the color.
Throwing my hat in here;
I've leveraged UIPopoverBackgroundViews in iOS 5+ to add a simple tintColor property onto UIPopoverControllers.
PCPopoverController: https://github.com/pcperini/PCPopoverController
I try to trick it by customizing the view controller inside the popover and then hiding the popover border using this code:
UIView * border = [[insideViewController.view.superview.superview.superview subviews] objectAtIndex:0];
border.hidden = YES;
The app is actually still in development so I'm hoping other people will comment on this solution.
check out these latest projects leveraging UIPopoverBackgroundView
https://github.com/CRedit360/C360PopoverBackgroundView
https://github.com/GiK/GIKPopoverBackgroundView
from ios 5 onward it is can be done, here is a library
https://github.com/ddebin/DDPopoverBackgroundView
just look at the documentation , and it is quite easy
good luck
You can use Elegant Popover cocoapod for just that. You can customise shape and colour of the arrow and the popover itself. Also, you can add colourful borders to the popover.
I know this is a lousy constructed answer, but I've just been playing with the UIPopoverController's views. They do exist.
The only way to access them is from your view that is sitting in the UIPopovercontroller.
I have a navigation controller so I follow this hierarchy
UIView *test = ((UIView *)[[[self.navigationController.view.superview.superview.subviews objectAtIndex:0] subviews] objectAtIndex:1]);
UIView *test2 = ((UIView *)[[[self.navigationController.view.superview.superview.subviews objectAtIndex:0] subviews] objectAtIndex:1]);
test.backgroundColor = [UIColor greenColor];
test2.backgroundColor = [UIColor greenColor];
This isn't exactly the end goal, but it is really close.
you'll find that the_view_in_the_popover.superview.superview (maybe just one superview if you are not reaching out from a navigation controller view) is a UIPopoverView. If you cast it as a UIView and treat it as a UIView you're not really breaking any rules. I guess that is really up to apple though.
Remove UIPopoverController border:
NSArray* subviews = ((UIView*)[popupController.contentViewController.view.superview.superview.superview.subviews objectAtIndex:0]).subviews;
for(UIView *subview in subviews){
[subview removeFromSuperview];
}
