I have scoured the net for this question and have came up empty handed. I have an app that I'm making which I want the user to be able to view an image i have hooked up to the UIImageView to show fullscreen. Basically by tapping the UIImageView it would make the buttons and status bar disappear until image is tapped again. I know this is probably a simple animations block that i would throw in my viewdidload or where I call my image from. I'm just unsure where it goes.
here is where my image comes from if the helps.this is in my .m file
-(void)viewDidLoad {////Loads UIImageView from URL
todaysWallpaper.image = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:#"http://www.inkdryercreative.com/daily/archive/mondays/images/062-mondays-960x640-A.jpg"]]];
I have four buttons that appear on screen. i want it to resemble the feel you get in the native photos app when you look and a picture and everything else on screen dissolves. Any help or guidance would be great. I can send additional code if needed
CGRect *oldFrame = todaysWallpaper.frame; // store this somewhere for when you go back
CGRect *newFrame = [[UIScreen mainScreen] bounds];
[UIView animateWithDuration:0.5 animations:^{
todaysWallPaper.frame = newFrame;
}];

I am working on attach images into MFMailComposeViewController everything is fine working but i want to know that is it Possible to give animation of Attachment?
For Ex:- When we attach images from Photo Gallery in iPhone Device. and while select mail Button that all selected Images Move's in MailComposeViewcontroller with Nice ANIMATION.
So please can any-buddy guide me this stuff is possible or not.? and if YES then how can i set Animation of Attachment.
There exists some semi-solution. You can in fact add any UIView as subview of you main app's window. It will than sit on top of all apps content. Using this you can simulate animation of attaching image to MailComposeViewcontroller
See my example code. This code slides image view from top of the screen to mail composer so it imitates adding of image as attachment. Everything is commented.
// Get apps main window
UIWindow *window = [[UIApplication sharedApplication] keyWindow];
// Setup frames of animated image view in apps window - adjust to your needs
CGRect finalImageFrame = CGRectMake(30, 220, window.frame.size.width-60, 100);
CGRect initialImageFrame = finalImageFrame;
initialImageFrame.origin.y = -initialImageFrame.size.height;
// Create image view to be animated as attachment
UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"myImage"]];
imageView.frame = initialImageFrame;
imageView.backgroundColor = [UIColor redColor];
// Add animated image view to window
[window addSubview:imageView];
// Animate image view with slide in from top
[UIView animateWithDuration:0.4
animations:^{
imageView.frame = finalImageFrame;
}];
// Present mail composer
[self presentViewController:mailComposer animated:YES completion:^{
// Once the controller appears, hide the image view - adjust this animation according to you needs
[UIView animateWithDuration:0.4
animations:^{
imageView.alpha = 0;
} completion:^(BOOL finished) {
[imageView removeFromSuperview];
}];
}];
Of course the code may need some adjustments and polishing, but it shows the concept. You can play with animations to make some better effect. There is a lot of animation tweaks I would add, but I wanted to keep the example code as short at it can be ;-)
That is iOS custom animation effects and is not exposed as iOS API's so no you cannot get this effect out of box. The reason I know that this effect is not exposed to developers is from Apple iOS 6 Docs. There is only one method which deals with animate and its the standard one.
What you can try is this. After the user has selected image(s) from his photo gallery (i.e. from ALAssetsLibrary) you can animate a "image" that looks like a MFMailComposeViewController. The animation would similar to what iOS provides i.e. background fading, MFMailComposeViewController appearing and the images sitting in the "body" section of the mail. Once the animation finishes, remove the "image" of MFMailComposeViewController and show the actual call MFMailComposeViewController invoked with animaiton:FALSE option. Hope I was clear. Essentially what you are providing is an illusion of MFMailComposeViewController and once animation is done, taking away the illusion and showing the reality.
Theoretically this could work but exact animation timing and user perceived feel has to be tested out.
I have a white flash that appears to alert the user that a picture was taken but the white flash doesn't add light to my photos. My photos are still dark no matter what I have done. I have changed the duration of the flash and moved
[[self captureManager] captureStillImage];
to take pictures after the flash and still no luck. I have looked at the photo booth app on my Macbook and it seems that the flash comes just a little bit before the image is captured and it provides light to the photos in the dark. I want to replicate this. Can anyone help me?
- (IBAction)captureStillImage2:(id)sender
{
// Capture a still image
[[self stillButton] setEnabled:NO];
// Flash the screen white and fade it out to give UI feedback that a still image was taken
UIView *flashView = [[UIView alloc] initWithFrame:[[self videoPreviewView] frame]];
[flashView setBackgroundColor:[UIColor whiteColor]];
[[[self view] window] addSubview:flashView];
[UIView animateWithDuration:1.0f
animations:^{
[[self captureManager] captureStillImage];
[flashView setAlpha:0.f];
}
completion:^(BOOL finished){
[flashView removeFromSuperview];
[flashView release];
}
];
}
Try increasing the brightness using something like [[UIScreen mainScreen] setBrightness:1.0]; for iOS5+ .
Keep in mind though, that the effect on a small display like an iphone won't be able to match the effect of a full sized macbook pro (it's all about brightness and backlit area).
I'm trying to get my code to programmatically zoom into a small area of the larger picture. I'll add the tap code later, but right now I just want to see it work.
The zoomToRect in this code does absolutely nothing and I simply don't understand why. When I build it, the image just sits there at the 0,0 origin.
I've tried using:
setContentOffset and scrollRectToVisible and both these work fine -the image moves to the specified coordinates. But neither of these is what I want, because I need to move and zoom the image, not just move it.
But zoomToRect utterly refuses to do anything. I've read about 50 pages of examples and tutorials on this now and not a damn thing works. I'm tearing my hair out not knowing why. Clearly I'm missing some really fundamental or important point.
UIImage *myFirstImage = [UIImage imageNamed:#"manga_page.jpg"];
UIImageView *myFirstImageView = [[UIImageView alloc] initWithImage:myFirstImage];
[myFirstImageView setFrame:CGRectMake(0, 0, myFirstImage.size.width, myFirstImage.size.height)];
UIScrollView *myFirstScrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
[myFirstScrollView setContentSize:CGSizeMake(myFirstImage.size.width, myFirstImage.size.height)];
[myFirstScrollView addSubview:myFirstImageView];
[self.view addSubview:myFirstScrollView];
[myFirstScrollView zoomToRect:CGRectMake(300, 300, 300, 300) animated:YES];
The problem was that I hadn't defined the delegate for zooming - see viewForZoomingInScrollView (bottom of page) here:
https://developer.apple.com/library/ios/documentation/uikit/reference/uiscrollviewdelegate_protocol/Reference/UIScrollViewDelegate.html#//apple_ref/occ/intfm/UIScrollViewDelegate/viewForZoomingInScrollView
I don't have a code fragment in Objective C as I switched to the Xamarin framework. However the C# solution is as follows:
scrollView.ViewForZoomingInScrollView = delegate (UIScrollView sv) { return imageView; };
Where imageView is the UIImageView containing the image to be scrolled around.
Set the maximumZoomScale and minimumZoomScale properties for the UIScrollView.
I use TapJoy SDK in my an OpenGL based game (based on Maze+ code)
when i use the following code in the App Delegate to show full screen ads
[TapjoyConnect showFeaturedAppFullScreenAd];
or even use the following code in the more games view to show more games
[TapjoyConnect showOffersWithViewController:self withInternalNavBar:NO];
i got all my View controllers (like more games view and news view) rotated see the screen shot
do you have any idea how to fix this problem?
Adding this line should fix the problem.
[vc.view setTransform: CGAffineTransformMakeRotation(M_PI / 2)];
It should come before this:
vc.view.frame = view.frame;
[view addSubview:vc.view];
I have created a project which consist of a tabbarcontroller and a navigationcontroller.
The first view or the first tab is a tableview controller. Now i need to add a splashscreen to my application, so when the app loads it will show a welcome screen and then land on the tableviewcontroller.
My workings so far;
This is added in my viewDidLoad method.
myImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"splash.jpg"]];
myImageView.frame = [[self view] frame];
[self.view addSubview:myImageView];
[self.view bringSubviewToFront:self.myImageView];
The problem is that the splash screen or the UIImageView loads inside the tabbarController/NavigationController, and it does not take the full width and length of the screen. What should i do to fix this programatically ?
In application bundle you need to copy the splash screen images with the name "Default.png" and "Default#2x.png" for Retina. The app will load this automatically, you don't need to do more work.
Here you have a link for this: http://iosdevelopertips.com/cocoa/defaultpng-the-secret-of-the-load-screen.html
Add the images that you want to use to the resources of your project and name them Default.png and Default#2x.png (if you are providing it for a retina screen). Be sure no name them exactly. If you get the capitalisation wrong, it will work in the Simulator (which is not case-sensitive), but not on the device (which is case-sensitive).
Be aware that a "splash screen" is discouraged by the Apple Human Interface Guidelines:
Have you given the Launch Images a look in your target settings?
You would probably want to add the splash screen in the app delegate's didFinishLaunchingWithOptions method. Then start an animation of fade out (or whatever animation you need). Finally removing the splash screen view when the animation is complete.
You have to add the UIImageView to the root's view:
UIView *rootView = [[[[UIApplication sharedApplication] delegate] viewController] view];
[myImageView setFrame:rootView.bounds];
[rootView addSubview:myImageView];
you can use the uiimage view to add an array of images to play an animation, try the following
code in
-(void)viewDidAppear:(BOOL)animated {
animationSplashImageView.animationImages = imageArray;
animationSplashImageView.animationDuration = 5;
animationSplashImageView.animationRepeatCount = 1;
[animationSplashImageView startAnimating];
}
IBOutlet UIImageView* animationSplashImageView;
was defined in the main view of your app.
also you could test your splash using tool Splashx Free, which is on Apple App Store: http://itunes.apple.com/cn/app/splashx-free/id500137095?mt=8
