AXPopoverView is an iOS customizable view that displays a bubble style view with a custom view when some messages need to show from a target view or a target rect. AXPopoverView contains how to use custom view to customize the popover view. The popover view (mostly used as Label or Other) is a convenient and hommization way for developer to use.

• Popover animation
• Customizable
• Translucent blur effect support
• Customizable animator block support
• UI_APPEARANCE_SELECTOR configuration
• Scrollable

AXPopoverView works on any iOS version after iOS 7.0. It depends on the following Apple frameworks, which should already be included with most Xcode templates:

• Foundation.framework
• UIKit.framework
• CoreGraphics.framework

You will need the latest developer tools in order to build AXPopoverView. Old Xcode versions might work, but compatibility will not be explicitly maintained.

CocoaPods is the recommended way to add AXPopoverView to your project.

1. Add a pod entry for AXPopoverView to your Podfile pod 'AXPopoverView', '~> 0.2.0'
2. Install the pod(s) by running pod install.
3. Include AXPopoverView wherever you need it with #import "AXPopoverView.h".

Alternatively you can directly add the AXPopoverView.h and AXPopoverView.m source files to your project.

1. Download the latest code version or add the repository as a git submodule to your git-tracked project.
2. Open your project in Xcode, then drag and drop AXPopoverView.h and AXPopoverView.m onto your project (use the "Product Navigator view"). Make sure to select Copy items when asked if you extracted the code archive outside of your project.
3. Include AXPopoverView wherever you need it with #import "AXPopoverView.h".

AXPopoverView support UI_APPEARANCE_SELECTOR to configure look of popover view will display on the screen. You should add your customizable code to configuration block when you using the + instance methods.

Using showInRect:animated:completion: hideAnimated:afterDelay:completion: to show popover view or hide. You can also using convenient methods to show the popover label like this:

[AXPopoverLabel showFromView:sender animated:YES duration:2.0 title:@"Your title." detail:@"Your detail contents." configuration:nil];

Oh, that's easy!!!

Using the selector masked as UI_APPEARANCE_SELECTOR to custimize the popover view when application has started.

[[AXPopoverView appearance] setBackgroundColor:[UIColor colorWithRed:0.165f green:0.639f blue:0.937f alpha:1.00f]];
[[AXPopoverView appearance] setBackgroundDrawingColor:[UIColor colorWithRed:0.165f green:0.639f blue:0.937f alpha:1.00f]];
[[AXPopoverView appearance] setPreferredArrowDirection:AXPopoverArrowDirectionTop];
[[AXPopoverView appearance] setTitleTextColor:[UIColor whiteColor]];
[[AXPopoverView appearance] setDetailTextColor:[UIColor whiteColor]];
[[AXPopoverView appearance] setArrowConstant:6];
[[AXPopoverView appearance] setTranslucentStyle:AXPopoverTranslucentDefault];
[[AXPopoverView appearance] setAnimator:[AXPopoverViewAnimator animatorWithShowing:^(AXPopoverView * _Nonnull popoverView, BOOL animated, CGRect targetRect) {
    if (animated) {
        CGRect fromFrame = CGRectZero;
        fromFrame.origin = popoverView.animatedFromPoint;
        popoverView.transform = CGAffineTransformMakeScale(0, 0);
        popoverView.layer.anchorPoint = popoverView.arrowPosition;
        [UIView animateWithDuration:0.5 delay:0.0 usingSpringWithDamping:0.5 initialSpringVelocity:0.5 options:7 animations:^{
            popoverView.transform = CGAffineTransformIdentity;
        } completion:^(BOOL finish) {
            // Call `viewDidShow:` when the animation finished.
            if (finish) [popoverView viewDidShow:animated];
        }];
    }
} hiding:nil]];

Simply using a block to customize a specific popover view will show.

[AXPopoverView showFromView:sender animated:YES duration:2.0 title:@"Your title." detail:@"Your detail contents." configuration:^(AXPopoverView *popoverView) {
popoverView.showsOnPopoverWindow = NO;
popoverView.translucent = NO;
popoverView.preferredArrowDirection = AXPopoverArrowDirectionTop;
popoverView.translucentStyle = AXPopoverTranslucentLight;
}];

You can also use as this:

AXPopoverView *popoverView = [AXPopoverView new];
popoverView.title = @"Your title.";
popoverView.detail = @"Your detail contents.";
popoverView.showsOnPopoverWindow = NO;
popoverView.translucent = NO;
popoverView.preferredArrowDirection = AXPopoverArrowDirectionTop;
popoverView.translucentStyle = AXPopoverTranslucentLight;
[popoverView showFromView:sender animated:YES duration:2.0];

UI updates should always be done on the main thread. like setOffsets:, setArrowAngle:, setTitleFont:, setDetailFont:, setTranslucent:, setArrowCornerRadius: and so on.

If you need to run your long-running task in the main thread, you should perform it with a slight delay, so UIKit will have enough time to update the UI (i.e., draw the HUD) before you block the main thread with your task.

if ([NSThread isMainThread]) {
/// Do updaing.
} else {
dispatch_async(dispatch_get_main_queue(), ^{
/// Do updating.
});
}

Updating...

Deleted AXPopoverLabel and merged AXPopoverLabel to AXPopoverView. You can use AXPopoverView instead of AXPopoverLabel. Enjoy!!!

Added:

• 1. indicator view.
• 2. progress view.
• 3. button items.
• 4. custom header view and footer view for customization.

Updated pod spec file to 0.3.0

Added animator of animation to customize a showing/hiding animation. Both are using block. See AXPopoverView+Animator for more details.
