I have added splash screen by doing project->General tab-> Launch Images->
From here i have taken two images according to the size and its working very fine too.
Now i want to put an Activity Indicator onto it.
So before loading of my DB and files, the splash as well as the indicator should be displayed.
What can i do for this?
I also tried after some suggestions
i did like this
[self performSelector:#selector(loadingViewFade) withObject:nil];
(void) loadingViewFade
loadingView = [[UIImageView alloc] initWithFrame:CGRectMake(0,0, 320, 480)];
loadingView.image = [UIImage imageNamed:#"splashscreen_640x960"];
[_window addSubview:loadingView];
[_window bringSubviewToFront:loadingView];
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:3.0];
[UIView setAnimationDelay:3.0];
[UIView setAnimationTransition:UIViewAnimationTransitionNone forView:_window cache:YES];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:#selector(startupAnimationDone:finished:context:)];
loadingView.alpha = 0.5f;
[UIView commitAnimations];
//Create and add the Activity Indicator to loadingView
UIActivityIndicatorView *activityIndicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite];
activityIndicator.alpha = 1.0;
activityIndicator.center = CGPointMake(160, 430);
activityIndicator.hidesWhenStopped = NO;
UILabel *text = [[UILabel alloc]initWithFrame:CGRectMake(140, 435, 160, 30)];
text.backgroundColor = [UIColor clearColor];
text.textColor = [UIColor whiteColor];
text.font = [UIFont systemFontOfSize:14];
text.text = #"Loading...";
[loadingView addSubview:text];
[loadingView addSubview:activityIndicator];
[loadingView addSubview:activityIndicator];
[activityIndicator startAnimating];
(void)startupAnimationDone:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context
[loadingView removeFromSuperview];
Again the splash as well as the indicator isnt displaying rather the default screen is being loaded untill the database loads.. Please help me out
I think you should create your own splash screen, and add a UIActivityIndicator to this splash screen by programmatically.
project->General tab-> Launch Images-> will add the default splash or loading screen to your project. You can not show activity indicator on the default image. To show loading message to Activity indicator you need to add your splash view controller which has the background image as default image which you set before. Also one Activity indicator to show the loading status. Once you are done with loading of database and other thing stop animating activity indicator and dismiss the splash screen.

I am showing spinner(UIActivityIndicator) while download is going on. It shows spinner as download starts, but it doesn't stop showing once download is finished. i have seen some question for the same issue but did not help. I need to make it work in ios7 as well as iOS8.
I am using below code...
- (void) startSpinner:(NSString *)message {
container = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 100)];
container.center = self.view.center;
container.backgroundColor = [UIColor colorWithRed:0.9 green:0.9 blue:0.9 alpha:0.4];
container.layer.cornerRadius = 10;
container.layer.masksToBounds = true;
container.tag = 134;
activityLabel = [[UILabel alloc] init];
activityLabel.frame = CGRectMake(0, 70, 100, 30);
activityLabel.text = message;
activityLabel.textColor = [UIColor darkGrayColor];
activityLabel.textAlignment = NSTextAlignmentCenter;
activityLabel.font = [UIFont boldSystemFontOfSize:10];
[container addSubview:activityLabel];
activityIndicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];
activityIndicator.center = CGPointMake(container.frame.size.width/2, container.frame.size.height/2);
[container addSubview:activityIndicator];
[self.view addSubview:container];
[activityIndicator startAnimating];
}
-(void)stopSpinner{
[activityIndicator stopAnimating];
container = [self.view viewWithTag:134];
[container removeFromSuperview];
activityIndicator = nil;
NSLog(#"activity indicator should be removed %#",activityIndicator);
}
And one more issue it does not show spinner in the center of the device screen.
Any help will be appreciated....
There are a few things wrong here.
container.center = self.view.center;
If you are trying to center the container in self.view, then this won't do it. self.view.center is the center of the view's frame but you would need to use the center of the view's bounds. Here is the corrected code:
container.center = CGPointMake(CGRectGetMidX(self.view.bounds), CGRectGetMidY(self.view.bounds));
You also need to change how you set the activity indicator's frame:
activityIndicator.center = CGPointMake(CGRectGetMidX(container.bounds), CGRectGetMidY(container.bounds));
Also, if you call startSpinner more than once, you can have more than one spinner added to the view, which could possibly be the reason your spinner doesn't seem to be stopping. I recommend that you alloc and init only one spinner and do it in the class constructor. You can do the same with the container and activityLabel objects. Alternatively, you could call stopSpinner at the top of startSpinner (and add some null-checks in stopSpinner to avoid referencing a null pointer).
It's impossible to say for sure based on your code why it appears that the spinner doesn't stop, but my guess is that you're calling startSpinner several times in a row without any intervening call to stopSpinner.
If you're only calling stopSpinner once then verify that you're doing so in the main thread.
You can add the spinner view on navigation controller, so it will look at the center as you want. I think this will solve your problem.
[self.navigationController.view addSubview:coverView];
And don't forget to remove it from self.navigationController.view
I am trying to make a slide out notification bar for when the app receives a notification and the app is currently open and in the foreground. I got this working with a custom UIView (actually it's a UIButton) and an animation. For some reason though it won't register a press when I tap on it. It won't call the selector method. Code is below:
-(void)appOpenPush {
//get string
NSLog(#"got a push while app was open");
AppDelegate *appDelegate =(AppDelegate *)[[UIApplication sharedApplication] delegate];
NSString *pushString = appDelegate.pushString;
//play sound
AudioServicesPlaySystemSound(MessageSound);
AudioServicesPlayAlertSound(kSystemSoundID_Vibrate);
//note I am actually using a button here
UIButton *pushView =[[UIButton alloc] initWithFrame:CGRectMake(0, -75, [[UIScreen mainScreen] bounds].size.width,75)];
pushView.backgroundColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:0.8];
[pushView addTarget:self action:#selector(pushSlidePress) forControlEvents:UIControlEventTouchUpInside];
//set image
UIImageView *logo = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"icon120.png"]];
logo.frame=CGRectMake(5, 20, 35, 35);
logo.layer.cornerRadius=8;
logo.clipsToBounds=YES;
[pushView addSubview:logo];
UILabel *pushLabel = [[UILabel alloc] initWithFrame:CGRectMake(48, 34, 0, 0)];
pushLabel.text=pushString;
pushLabel.font=[UIFont systemFontOfSize:13];
[pushLabel sizeToFit];
pushLabel.textColor=[UIColor whiteColor];
[pushView addSubview:pushLabel];
//animate
UIWindow* currentWindow = [UIApplication sharedApplication].keyWindow;
[currentWindow addSubview:pushView];
[UIView animateWithDuration:0.4 delay:0.0 options:UIViewAnimationOptionCurveEaseIn animations:^{
pushView.frame = CGRectMake(0, 0, [[UIScreen mainScreen] bounds].size.width,75);
} completion:^(BOOL finished) {
[UIView animateWithDuration:0.4 delay:2.0 options:UIViewAnimationOptionCurveEaseIn animations:^{
pushView.frame = CGRectMake(0, -75, [[UIScreen mainScreen] bounds].size.width,75);
} completion:^(BOOL finished) {
[pushView removeFromSuperview];
}];
}];
}
Could anyone give me a pointer to why this isn't working? Is it because I am adding the UIButton to the main window? Any tips would be really helpful. thanks!
You have to add UIViewAnimationOptionAllowUserInteraction as an option to both of your animation blocks.
As per the documentation :
"Allow the user to interact with views while they are being animated."
Try this to avoid logo and pushLabel receive touches events:
logo.userInteractionEnabled = NO;
pushLabel.userInteractionEnabled = NO;
So it turns out you can't simply detect a press if the button is moving. I tested this by just adding the frame setup without it animating and it registered the press, when animation is turned on it doesn't. Seems that UIButton doesn't have tracking built in. I did come up with a quick fix. I just made a button the same size as the total animation area (i.e. the size of my slide out bar) and added that to the currentWindow on top of the animation frame. So it's just a clear invisible button on top of the animation but it's not moving itself. i.e:
UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(0, 0,[[UIScreen mainScreen]bounds].size.width , 75)];
[button addTarget:self action:#selector(pushSlidePress) forControlEvents:UIControlEventTouchUpInside];
[currentWindow addSubview:button];
[UIView animateWithDuration:0.4 delay:0.0 options:(UIViewAnimationOptionCurveEaseIn | UIViewAnimationOptionAllowUserInteraction) animations:^{
pushView.frame = CGRectMake(0, 0, [[UIScreen mainScreen] bounds].size.width,75);
} completion:^(BOOL finished) {
[UIView animateWithDuration:0.4 delay:2.0 options:(UIViewAnimationOptionCurveEaseIn | UIViewAnimationOptionAllowUserInteraction) animations:^{
pushView.frame = CGRectMake(0, -75, [[UIScreen mainScreen] bounds].size.width,75);
} completion:^(BOOL finished) {
[pushView removeFromSuperview];
[button removeFromSuperview];
}];
}];
Obviously you are covering an area of the screen that might block other things being pressed, but it depends on your setup. The animation is quick and I only have one button that the notification bar will block and it's too quick to notice. Hopefully this will be helpful to someone else trying to achieve a similar thing. Thanks for your help guys.
Hi I'm trying to upload image's from iphone to server in that i given activity indicator for the user to known that image is uploading while clicking upload it will show activity indicator for few minutes.
But my problem is the activity indicator only showing in few images its not showup on all the images pls tell me how to resolve this.
my activity coding .
-(void)temp{
spinner = [[UIActivityIndicatorView alloc initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];
//spinner = [[UIActivityIndicatorView alloc]initWithActivityIndicatorStyle:]
spinner.frame = CGRectMake(0.0, 0.0, 40.0, 40.0);
[spinner setCenter:CGPointMake(160, 240)]; // (mid of screen) I do this because I'm in landscape mode
[self.view addSubview:spinner];
spinner.color = [UIColor blackColor];
spinner.backgroundColor = [UIColor colorWithWhite:0.2 alpha:0.4];
[spinner startAnimating];
[spinner release];
}
-(void) myMethod{
[spinner stopAnimating];
spinner.hidden = YES;
spinner.color = [UIColor yellowColor];
}
- (IBAction)pushUpload:(id)sender {
[self temp];
[self performSelector:#selector(myMethod) withObject:nil afterDelay:5.0f];
}
Instead of ActivityIndicator use AsynchronousImageView It will automatically add activityindicator while loading an image.
[AsynObj loadImageFromURL:[NSURL URLWithString:ImageUrl]];
You can get the AsyncImageView classes from the following link https://github.com/nicklockwood/AsyncImageView
I hope it will help!
I'm having a problem with UI animations.
I have a uiview: theView.
I animate theView to move to some random position on the mainView. It moves from point A to point B and changes its scale from 1.0 to 1.5;
So after the animation, the view is bigger and in a new position.
I call a second animation, by button. This one only move theView.
After the animation, the view has moved. However, the view is no longer bigger, its scale is back at 1.0.
So do these animation values not become theViews new values for size,position,ex?
I will post code soon, because it of course may be a careless error I am missing.
If its UIView animation.
- (void)viewDidLoad
{
[super viewDidLoad];
_yourView = [[UIView alloc]initWithFrame:CGRectMake(300, 300, 100, 100)];
[_yourView setBackgroundColor:[UIColor redColor]];
[self.view addSubview:_yourView];
[UIView animateWithDuration:1.0f animations:^{
[_yourView setFrame:CGRectMake(400, 400, 150, 150)];
} completion:nil];
UIButton *aMoveButton = [[UIButton alloc] initWithFrame:CGRectMake(10.0f, 5.0f, 60.0f, 40.0f)];
[aMoveButton setTitle:#"MoveView" forState:UIControlStateNormal];
[aMoveButton addTarget:self action:#selector(moveYourView) forControlEvents:UIControlEventTouchDown];
[self.view addSubview:aMoveButton];
}
-(void)moveYourView{
[UIView animateWithDuration:1.0f animations:^{
[_yourView setFrame:CGRectMake(300, 500, 150, 150)];
} completion:nil];
}
Believe me this works and it actually changes the view's values for size,position.
I cannot post a comment, so I would just like to suggest that you say UIView, i'm not 100% sure, so dont take my word for it, but im pretty sure you should use UIImageView instead. Hope that helps a little :)
// create the view that will execute our animation
UIImageView* campFireView = [[UIImageView alloc] initWithFrame:self.view.frame];
// load all the frames of our animation
campFireView.animationImages = [NSArray arrayWithObjects:
[UIImage imageNamed:#"campFire01.gif"],
[UIImage imageNamed:#"campFire02.gif"],
[UIImage imageNamed:#"campFire03.gif"],
[UIImage imageNamed:#"campFire04.gif"],
[UIImage imageNamed:#"campFire05.gif"],

// all frames will execute in 1.75 seconds
campFireView.animationDuration = 1.75;
// repeat the annimation forever
campFireView.animationRepeatCount = 0;
// start animating
[campFireView startAnimating];
// add the animation view to the main window
[self.view addSubview:campFireView];
In my UIViewController's loadView method I start a UIActivityIndicator. Later in loadView I load a complex UIView, which takes about 2-3 secs to load. (UIScrollView with a lot of pictures more specifically). My problem is that the UIActivityIndicator spinner is only visible, after my other layer has loaded too. (which is of course useless to me). What is a correct way to handle this?
- (void)loadView {
CGRect fullScreenRect=[[UIScreen mainScreen] bounds];
UIView *contentView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, 340, fullScreenRect.size.width)]autorelease];
self.view = contentView;
spinner = [[[UIActivityIndicatorView alloc]initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite] autorelease];
spinner.frame = CGRectMake(0.0, 0.0, 40.0, 40.0);
spinner.center = self.view.center;
[self.view addSubview:spinner];
[spinner startAnimating];
scrollView=[[[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 340, fullScreenRect.size.width)]autorelease];
...setting up scrollView...
[self.view addSubview:scrollView];
}
- (void)viewDidLoad
{
[super viewDidLoad];
[spinner removeFromSuperview];
}
I have found a somewhat similar thread:
UIActivityIndicatorView not showing until after loading done
But it suggests to load things in a background thread, but loading and displaying a UIView is only possible in the main thread as far as I know.
I am a beginner, and sorry if my question is fundamentally wrong.
I managed to make it the way Carl Veazey suggested. It was pretty easy actually. I spawned a new background thread, and loaded my UIScrollView there.
I used, in LoadView:
spinner = [[[UIActivityIndicatorView alloc]initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite] autorelease];
spinner.frame = CGRectMake(0.0, 0.0, 40.0, 40.0);
spinner.center = self.view.center;
[self.view addSubview:spinner];
[spinner startAnimating];
[self performSelectorInBackground:#selector(populateScrollView) withObject:nil];
And:
-(void) populateScrollView{
...creating scrollView...
[self.view addSubview:scrollView];
[spinner removeFromSuperview];
}
It works perfectly. What is really weird for me, is that I am adding the scrollview to the UI in a background thread, not in the main thread. I thought I could only mess with the UI in the main thread.
(I could do the same thing with GCD. When the background thread finished loading the scrollview, I could display scrollview in the main thread's queue. But the former solution somehow works as well...)
Sorry for ugly text formatting.
There is a very cute way to do what you want.
Firstly you have to show the indicator view and only after a little amount of time (0.1 sec or even lesser) you ask your scrollView to populate.
- (void)loadView {
CGRect fullScreenRect=[[UIScreen mainScreen] bounds];
UIView *contentView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, 340, fullScreenRect.size.width)]autorelease];
self.view = contentView;
spinner = [[[UIActivityIndicatorView alloc]initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite] autorelease];
spinner.frame = CGRectMake(0.0, 0.0, 40.0, 40.0);
spinner.center = self.view.center;
[self.view addSubview:spinner];
[spinner startAnimating];
double delayInSeconds = 0.1;
dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(delayInSeconds * NSEC_PER_SEC));
dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
scrollView=[[[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 340, fullScreenRect.size.width)]autorelease];
...setting up scrollView...
[self.view addSubview:scrollView];
});
}
Try this simple method, Its working well for me....
UIActivityIndicatorView *activityIndicator= [[UIActivityIndicatorView alloc]initWithFrame:CGRectMake(0, 0, 50, 50)];
activityIndicator.layer.cornerRadius = 05;
activityIndicator.opaque = NO;
activityIndicator.backgroundColor = [UIColor colorWithWhite:0.0f alpha:0.6f];
activityIndicator.center = self.view.center;
activityIndicator.activityIndicatorViewStyle = UIActivityIndicatorViewStyleGray;
[activityIndicator setColor:[UIColor colorWithRed:0.6 green:0.8 blue:1.0 alpha:1.0]];
[self.view addSubview: activityIndicator];
Add following lines while load your view
//-- Add this line while processing to load your view
[activityIndicator startAnimating];
//-- Add this line when after you view loaded
[activityIndicator stopAnimating];
