  • JYGraphViewController is a slightly adapted version of the graph that appears in Tempo/Weather. It is meant to be presented modally and using the whole screen. The demo application it belongs to here presents it using an orientation change notification, but it could be triggered via any action. The benefit of having it presented based on orientation is that you don't have to obscure the graph with any controls. From a UX point of view, animating the presentation helps the user understand the graph is affected by gravity: ie. slides out when device is turned into landscape, and falls back away when returned to portrait.

- (void) didRotate
{
    if ([UIDevice currentDevice].orientation == UIDeviceOrientationLandscapeLeft ||
        [UIDevice currentDevice].orientation == UIDeviceOrientationLandscapeRight) {

    JYGraphViewController *graphView = [[JYGraphViewController alloc] initWithNibName:@"JYGraphViewController" bundle:nil];

    // Set the data for the graph
    // Send only an array of number values
    graphView.graphData = [self createArrayOfNumbersToPassToGraph];

    // Set the xAxis labels (optional)
    // Can send numbers or strings (it's printed using stringWithFormat:"%@")

  • Flat Rounded Style

//Example
    self.flatRoundedButton = [[VBFPopFlatButton alloc]initWithFrame:CGRectMake(100, 150, 30, 30)
                                              buttonType:buttonMenuType
                                             buttonStyle:buttonRoundedStyle];
self.flatRoundedButton.roundBackgroundColor = [UIColor whiteColor];
self.flatRoundedButton.lineThickness = 2;
self.flatRoundedButton.tintColor = [UIColor flatPeterRiverColor];
[self.flatRoundedButton addTarget:self
                           action:@selector(flatRoundedButtonPressed)
                 forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:self.flatRoundedButton];
Flat Plain Style

//Example
    self.flatPlainButton = [[VBFPopFlatButton alloc]initWithFrame:CGRectMake(200, 150, 30, 30)
                                                   buttonType:buttonAddType
                                                  buttonStyle:buttonPlainStyle];
self.flatPlainButton.lineThickness = 2;
self.flatPlainButton.tintColor = [UIColor whiteColor];
[self.flatPlainButton addTarget:self
                         action:@selector(flatPlainButtonPressed)
               forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:self.flatPlainButton];
In both cases, you can use the following method to animate the button from one state to the next:

[flatRoundedButton animateToType:nextType];
This are the 9 types avaiable for the button:

typedef NS_ENUM(NSInteger, FlatButtonType) {
buttonDefaultType,             // Vertical line
buttonAddType,                 // +
buttonMinusType,               // -
buttonCloseType,               // x
buttonBackType,                // <
buttonForwardType,             // >
buttonMenuType,                 // 3horizontal lines
buttonDownloadType,
buttonShareType
};

  • Drop the OnboardingViewController and OnboardingContentViewController header and implementation files into your project, import them into your AppDelegate, and you're ready to create an awesome onboarding experience for your users!

Create individual pages by creating an OnboardingContentViewController, providing it a title, body, image, text for an action button, and within the action block handle whatever you want to do when the users press the button. If you don't want a button, you can leave both the button text and action handler nil.

OnboardingContentViewController *firstPage = [[OnboardingContentViewController alloc] initWithTitle:@"Page Title" body:@"Page body goes here." image:[UIImage imageNamed:@"icon"] buttonText:@"Text For Button" action:^{
    // do something here when users press the button, like ask for location services permissions, register for push notifications, connect to social media, or finish the onboarding process

  • ARTEmailSwipe is a UIViewController container, which allows you to have one view controller at the bottom, whilst keeping your main navigation separate. This is based on the iOS 8 emails implementation where you can have your new email open at the bottom whilst still viewing all your old emails above it. I also took a lot of inspiration from the JASidePanels project.


Example 1: Code

#import "ARTEmailSwipe.h"

实现文件中创建ARTEmailSwipe对象并初始化:
@implementation AppDelegate

@synthesize window = _window;
@synthesize viewController = _viewController;

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

    self.viewController = [[ARTEmailSwipe alloc] init];

  // you will want to use your own custom classes here, but for the example I have just instantiated it with the UIViewController class.
    self.viewController.centerViewController = [[UIViewController alloc] init];
    self.viewController.bottomViewController = [[UIViewController alloc] init];

    self.window.rootViewController = self.viewController;
    [self.window makeKeyAndVisible];
    return YES;
}

  • LFHeatMap is a simple UIImage generator. The resulting object can be used like any other UIImage, standalone or in a UIImageView. While it can be overlaid on top of a MKMapView, it is not strongly tied to this specific component and hence does not offer the benefits that come with a more complex implementation of MKOverlayRenderer.

Adding LFHeatMap to Your Project

CocoaPods

CocoaPods is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries like LFHeatMap in your projects. See the "Getting Started" guide for more information.

platform :ios, '5.0'
pod "LFHeatMap"
Source Files

Alternatively you can directly add the LFHeatMap folder to your project.

Demo

This demo plots the measured magnitudes of the 2011 Virginia Earthquake.

Running

Open and launch the LFHeatMapDemo XCode project.
Move the slider on the bottom to adjust the boost.
Explanation

The data is stored in quake.plist which is a simple plist storing the latitude, longitude, and magnitude of each measurement. The points (locations) and weights (magnitudes) are stored in two NSArray objects in viewDidLoad of LFHeadMapDemoViewController.

The main action takes place in the sliderChanged: function. Moving the slider determines the new boost value and generates a new heat map image. The image's dimensions are the same as the self.mapView object, with the points and weights supplied by the two data arrays. The image is then passed to the overlaying UIImageView that sits on top of the map.

LFHeatMap

This class contains the three basic static functions used to generate the heat maps.

1. Basic Heat Map

Supply the desired image dimensions and boost, as well as the point/value arrays. There should be a 1:1 mapping between these two arrays, that is each index in the points array should have a corresponding index in the weights array.

@params
rect: region frame
boost: heat boost value
points: array of NSValue CGPoint objects representing the data points
weights: array of NSNumber integer objects representing the weight of each point

@returns
UIImage object representing the heatmap for the specified region.

+ (UIImage *)heatMapWithRect:boost:points:weights:
2. Advanced Heat Map

Works generally the same as the basic heat map, but allows to tweak two additional parameters to control the "bleed" of heat rendering.

@params
rect: region frame
boost: heat boost value
points: array of NSValue CGPoint objects representing the data points
weights: array of NSNumber integer objects representing the weight of each point
weightsAdjustmentEnabled: set YES for weight balancing and normalization
groupingEnabled: set YES for tighter visual grouping of dense areas

@returns
UIImage object representing the heat map for the specified region.

+ (UIImage *)heatMapWithRect:boost:points:weights:weightsAdjustmentEnabled:groupingEnabled:
3. MKMapView Helper

Works the same as the basic heat map, but allows you to supply map-specific parameters. Pass an MKMapView object (typically the target you want to overlay), and an array of CLLocation objects corresponding to coordinates on the specified MKMapView object.

The function will convert these to the required CGRect/CGPoint values as needed.

@params 
mapView: Map view representing the heat map area.
boost: heat boost value
locations: array of CLLocation objects representing the data points
weights: array of NSNumber integer objects representing the weight of each point

@returns
UIImage object representing the heatmap for the map region.

+ (UIImage *)heatMapForMapView:boost:locations:weights:

  • Instead of showing a gray overlay before the user can start playing with your app (a common practice as of today), we thought it would be better to show these "tips" as needed according to the usage.

SALQuickTutorial supports showing a view with a title, an image and a message. By default, to close, the user just needs to tap the screen, but you can configure it to work with a dismiss button. Also, you can set a completion block to be called when the view is dismissed.

Here at Seeking Alpha we decided to shift, in our next iOS version, from the gray overlay to the quick tutorials when they are really needed.

We invite you to contribute with our first iOS open source project.

SALQuickTutorial

Usage

The extremely simple way

You can use the class method below, if you just want to show the quick tutorial without customizing too much:

[SALQuickTutorialViewController showIfNeededForKey:@"MyUniqueKey" title:@"This feature is awesome" message:@"It's the best feature ever developed in an iOS app" image:[UIImage imageNamed:@"myFeatureImage"]];
Calling this method will:

Verify if the user already saw this tutorial, according to the key you pass;
In case he didn't, will create the quick tutorial based on the title, message and image you pass. The default configurations are that dismiss is done by tapping anywhere, and no support for completion block when dismissed.
The simple way

Sometimes, you will want to disable the tap-anywhere-to-dismiss and add a Got it! button. Wow, SALQuickTutorial supports it! Or, maybe, you want your app to know when the user dismissed it.

    //first, verify if you have shown it already
    if ([SALQuickTutorialViewController needsToShowForKey:@"MyUniqueKey"]) {
        SALQuickTutorialViewController *quickTutorialViewController = [[SALQuickTutorialViewController alloc] initWithKey:@"MyUniqueKey" title:@"This feature is awesome" message:@"It's the best feature ever developed in an iOS app" image:[UIImage imageNamed:@"myFeatureImage"]];

        //if you want to enable dismiss only with the button:
        quickTutorialViewController.dismissesWithButton = YES;

        //if you want to set the completion block:
        [quickTutorialViewController setDidDismissCompletionHandler:^{
            [[[UIAlertView alloc] initWithTitle:@"SALQuickTutorialViewController supports completion block" message:[NSString stringWithFormat:@"Quick tutorial with key %@ was dismissed", @"MyUniqueKey"] delegate:nil cancelButtonTitle:nil otherButtonTitles:@"OK", nil] show];
        }];

        //just show it
        [quickTutorialViewController show];
    }

  • NOTE: This is has not yet been thoroughly tested and is in alpha, I would strongly advise against using this in any release builds.

MALoggingViewController is a real-time pseudo-console you can embed in your application, perfect for testing and debugging in the real world. Whether you are determining the reliability of network traffic while driving through areas with poor service, testing push notifications on ad-hoc builds while not connected to Xcode, or working out those pesky Core Location bugs, there's no need to carry around half of your development environment with you. No more driving around town with the Xcode console open, or having to handle logging to files and emailing them later to figure out what the heck happened - you can see all the data on your device, anywhere, in real time.

This is not meant to be a replacement for something like CocoaLumberjack, and is absolutely not optimized for speed or efficiency, but for day-to-day testing and debugging this is a pretty neat tool.

Usage
Drop MALoggingViewController.h/m into your project, import the header into your AppDelegate.h, and create a MALoggingViewController property on your AppDelegate.

You can put your MALoggingViewController anywhere in your application, keep it somewhere super-secret hidden with a password, or rip it out entirely for all your production builds. When you're ready to start logging important information on screen, simply call logToView: and pass in an NSLog-type message with arguments and the result will be added to the MALoggingView as well as logged normally to the console. From anywhere else in your application, all you need to do is access the AppDelegate's MALoggingViewController property and tell it what and when to log.

MALoggingViewController *loggingVC = [MALoggingViewController new];
self.logger = loggingVC;
[self.logger logToView:@"Some message goes here with param1: %@, param2: %@", firstParam, secondParam];
