Installation

###CocoaPods

The easiest way to get started is to use CocoaPods. Just add the following line to your Podfile:

pod 'PQFCustomLoaders', '~> 0.0.1'

###Import the project If you don't want to use (you should) CocoaPods, you can download this project, and add the files in the /PQFCustomLoaders folder to your existing project.

Quick Start

---

####1. Import

The first thing is to import the main file. This file contain all the requiered imports that you are going to need (PQFBarsInCircles.h PQFBouncingBalls.h PQFCirclesInTriangles.h). If you are planning to use only one loader, you can import only the required one, it is up to you.

#import <PQFCustomLoaders/PQFCustomLoaders.h>

####2. Init a loader in a view For example, if you are going to add the PQFBouncingBalls Loader, you have to initialize it like this. I recommend you to make a property in order to have a pointer to the loader for when you want to remove it.

@interface ViewController ()
...

@property (nonatomic, strong) PQFBouncingBalls *bouncingBalls;

...
@end

@implementation ViewController
...

self.loader = [[PQFBouncingBalls alloc] initLoaderOnView:self.view];

...
@end

In this example I am adding the loader to the main view, but you can add it to any UIView (or subclass)

####3. Customize it a little bit You can customize this loaders a lot, in the following section (Loader Styles) you can see all the custom properties that you can change.

self.loader.jumpAmount = 50;
self.loader.zoomAmount = 20;
self.loader.separation = 20;

It is very important to change all the properties before showing it (Except for the label ones).

####4. Show it! When the loader is initialized, it is going to be added to the subviews of the view that you choose. But it is going to be with alpha 0.0 and with no animations activated (so no memory problems ;) ).

[self.loader show];

When you use the show method, you are making it visible and activating the animations

####5. Hide it or Remove it If you are planning to reuse it, just hideit like this:

[self.loader hide]

Now you can change the properties that you want before reshowing it. This method makes it invisible and stop all the animations.

If you are not going to use it anymore, just remove it

[self.loader remove]

This method is going to remove it from it superview.

#####Methods you can use:

- (instancetype)initLoaderOnView:(UIView *)view;

- (void)remove;
- (void)show;
- (void)hide;
