使用方法

基本

demo展示了三种不同的提醒系统，包括Apple系统提醒、XFDialogBuilder和LGAlertView。
假设你想处理名为DEMOAlert的提醒系统，你可以按照以下步骤操作
创建一个新的类IRDEMOAlert，它继承自IRAlert并导入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

在内部编写创建DEMOAlert实例的初始代码

- (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;
}

重写IRAlert方法

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

让IRAlertAction为DEMOAlert工作，这是最困难的部分，你需要了解如何使用DEMOAlert，并让DEMOAlert调用IRAlertAction的处理程序。在这个例子中，DEMOAlert有actionHandler、cancelHandler和destructiveHandler，每个处理程序都与IRAlertAction映射

- (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);
        }
    };
}

使用IRAlertManager显示或隐藏提示框。

[[IRAlertManager sharedInstance] showAlert:alert];

[[IRAlertManager sharedInstance] hideAlert:alert];

使用IRAlertManager显示或隐藏全局加载视图。

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

[[IRAlertManager sharedInstance] hideLoadingViewWithTarget:self];

使用加载视图显示DEMOAlert。

- (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];
}
