Usage

Basic

The demo show three diffrent alert systems, include Apple system alert, XFDialogBuilder, and LGAlertView.
Assum you want to handle with a alert system named DEMOAlert, you can follow as below:
Create a new class IRDEMOAlert extends IRAlert, and Import IRAlertManager

#import <IRAlertManager/IRAlertManager.h>typedef NS_ENUM(NSUInteger, IRDEMOAlertStyle) {
    IRDEMOAlertStyleAlert       = 0,
    IRDEMOAlertStyleActionSheet = 1
};@interface IRDEMOAlert : IRAlert- (instancetype)initWithTitle:(nullable NSString *)title
               message:(nullable NSString *)message
                 style:(IRDEMOAlertStyle)style
         buttonActions:(nullable NSArray<IRAlertAction *> *)buttonActions
    cancelButtonAction:(nullable IRAlertAction *)cancelButtonAction
destructiveButtonAction:(nullable IRAlertAction *)destructiveButtonAction;@end

Write the initial codes for create the DEMOAlert instanse inside

- (instancetype)initWithTitle:(nullable NSString *)title
               message:(nullable NSString *)message
                 style:(IRAlertLGStyle)style
         buttonActions:(nullable NSArray<IRAlertAction *> *)buttonActions
    cancelButtonAction:(nullable IRAlertAction *)cancelButtonAction
destructiveButtonAction:(nullable IRAlertAction *)destructiveButtonAction {
    if(self = [super init]){
        NSMutableArray<NSString *> * titles = [self titlesWithButtonActions:buttonActions];        alert = [[DEMOAlert alloc] initWithTitle:title message:message style:(DEMOAlertStyle)style buttonTitles:titles cancelButtonTitle:cancelButtonAction.title destructiveButtonTitle:destructiveButtonAction.title];        [self setupButtonActions:buttonActions cancelButtonAction:cancelButtonAction destructiveButtonAction:destructiveButtonAction];
        [self registerForKeyboardNotifications];
    }    return self;
}

Override IRAlert methods

-(void)setBlurWithRadius:(CGFloat)blurRadius tintColor:(UIColor *)tintColor saturationDeltaFactor:(CGFloat)saturationDeltaFactor;
-(void)setCornerRadius:(CGFloat)cornerRadius;
-(void)addAction:(IRAlertAction*)action;

Let the IRAlertAction work for DEMOAlert, this is the most difficualt part, you need know how to use DEMOAlert, and make DEMOAlert call the handler of IRAlertAction. In this example, DEMOAlert has actionHandler, cancelHandler, and destructiveHandler, and each handler is mapping to IRAlertAction

- (void)setupButtonActions:(NSArray<IRAlertAction *> * _Nullable)buttonActions cancelButtonAction:(IRAlertAction * _Nullable)cancelButtonAction destructiveButtonAction:(IRAlertAction * _Nullable)destructiveButtonAction {
    __weak IRDEMOAlert* wself = self;    alert.actionHandler = ^(DEMOAlert * _Nonnull alertView, NSUInteger index, NSString * _Nullable title) {
        if(index >= buttonActions.count)
            return;        IRAlertAction *action = [buttonActions objectAtIndex:index];
        action.handler(action);
    };    alert.cancelHandler = ^(DEMOAlert * _Nonnull alertView) {
        if (cancelButtonAction) {
            cancelButtonAction.handler(cancelButtonAction);
        }
    };    alert.destructiveHandler = ^(DEMOAlert * _Nonnull alertView) {
        if (destructiveButtonAction) {
            destructiveButtonAction.handler(destructiveButtonAction);
        }
    };
}

Show or Hide alert with IRAlertManager.

[[IRAlertManager sharedInstance] showAlert:alert];[[IRAlertManager sharedInstance] hideAlert:alert];

Show or Hide global loading view with IRAlertManager.

[[IRAlertManager sharedInstance] showLoadingViewWithTarget:self backgroundImage:[ViewController imageWithColor:[UIColor greenColor] Size:[UIScreen mainScreen].bounds.size]];[[IRAlertManager sharedInstance] hideLoadingViewWithTarget:self];

Show DEMOAlert with loading view

- (IBAction)showDEMOAlert:(id)sender {
    IRAlertAction *commitAction = [[IRAlertAction alloc] init];
    commitAction.title = @"OK";
    commitAction.style = IRAlertActionStyleDefault;    IRAlertAction *cancelAction = [[IRAlertAction alloc] init];
    cancelAction.title = @"Cancel";
    cancelAction.style = IRAlertActionStyleCancel;    alert = [[IRDEMOAlert alloc] initWithTitle:nil message:nil style:IRDEMOAlertStyleAlert buttonActions:@[commitAction] cancelButtonAction:cancelAction destructiveButtonAction:nil];    __weak IRAlert *wAlert = alert;
    commitAction.handler = ^(IRAlertAction * _Nonnull action) {
        [[IRAlertManager sharedInstance] hideAlert:wAlert];
    };
    __weak ViewController *wSelf = self;
    cancelAction.handler = ^(IRAlertAction * _Nonnull action) {
        [[IRAlertManager sharedInstance] hideLoadingViewWithTarget:wSelf];
    };    [alert setCornerRadius:20];
    [[IRAlertManager sharedInstance] showAlert:alert];
}
