BALoadingAnimations

An animated wrapper around asynchronous operations.

Performs code in blocks asynchronously while presenting a loading animation. When the work is done, the loading animation is removed from the view.

Styling / Configuration

Many loading animations:

• Spinner (Default)
• Ripple
• Wave
• Pulse
• Warp

BALoadingAnimationConfig class methods change a singleton, which is used as the default configuration for all BALoadingAnimations.

Use BALoadingAnimationConfig the class methods to style the loading animations.

OR...

Create your own and pass it into a BALoadingAnimation class method if you want it to be different than your own default.

Basic Use

Add outside an async call and remove after that operation is completed. Never wrap these animations around operations on the main thread. This may cause animations to be delayed

[BALoadingAnimation addBALoadingAnimation:BALoadingAnimationTypeDefault toView:self.view];
     dispatch_async(dispatch_get_global_queue( DISPATCH_QUEUE_PRIORITY_LOW, 0), ^{
 
       [self makeBigRequestWithURL:url];
 
        dispatch_async(dispatch_get_main_queue(), ^{
            [self removeBALoadingAnimationFromView:self.view];
 
        });
     });

** Or, if a function already is async and has a callback ** just use the add and remove functionality like in the example below:

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setHTTPMethod:@"GET"];
[request setURL:[NSURL URLWithString:url]];
__weak id weakSelf = self;

[BALoadingAnimation addBALoadingAnimation:BALoadingAnimationTypeDefault toView:self.view];

[NSURLConnection sendAsynchronousRequest:request queue:nil completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {
    
    [BALoadingAnimationConfig setMessage:@"handling response..."];
    id stuff = [weakSelf doSomethingWithResponse:response];
    [weakSelf doMoreWithStuff:stuff];
    [BALoadingAnimation removeBALoadingAnimationFromView:(UIView *)superView];
}];

Blocks

Any code placed in a BAExecutionBlock will be run asynchronously and wrapped in a BALoadinganimation that is removed before completion block is called.

__block NSString *results = @"";

[BALoadingAnimation runBALoadingAnimation:BALoadingAnimationTypeDefault onView:self.view whileExecuting:^{
    results = [self makeBigRequestWithURL:url];
} withCompletion:^{
    NSLog(@"%@", results);
}];

Custom Loading Animations

To create your own Custom loading animations subclass BAAnimationView and add a BALoadingAnimationType in the BALoadingAnimation.h file. Then update

+(CGRect)frameForAnimationType:(BALoadingAnimationType)animationType
and
*+(BAAnimationView )animationViewForAnimationType:(BALoadingAnimationType)animationType

appropriately in BALoadingAnimation.m.
