作者Meterwhite，源码SDMask，完美的弹出自定义视图，用户不再关心动画和点击事件。引导遮罩蒙版弹窗+事件&动画解耦。持续维护。

介绍 Introduce

• A perfect iOS mask view that help you to present custom view.User dont need to care about animations and events.

• Skir的（SD）iOS蒙版蒙层遮罩.弹出自定义视图，用户不再关心动画和点击事件。

• 点赞富一生.

• Good luck for one start .

Import

• Drag floder SDMask to your project.

#import "SDMask.h"

CocoaPods

pod 'SDMask'

New! 引导控制器 SDMaskGuidController

在一个XIB文件中设置多个页面的约束进行适配，可以适应90%的设计需求。Set multiple guid pages in one controller XIB file ! By changing the constraints in XIB to adapt the device, this solution can address 90% of the design needs.

[[[MySDMaskGuidController new] userViewDidLoad:^(SDMaskModel * _Nonnull model) {    /// Set the same color as user view to background.
    [model setBackgroundColor:[UIColor colorWithWhite:0 alpha:0.6]];
}] show];

处理简单业务 Handling simple business in a block.

[SDMaskUserView(customAlertView) sdm_showAlertUsingBlock:^(SDMask<UserView*>*  _Nonnull mask) {    /// You can bind control events to SDMask
    [mask bindEventForControls:@[okButton]] 
    [mask bindEventForCancelControl:cancelButton];
    [mask bindingEventsUsingBlock:^(SDMaskBindingEvent * event) {        if(event.index == 0){            /// okButton...
        }
    }];
    ... ...
}];

分步处理复杂的业务 Step-by-step processing of complex business.

SDMask<UserView*>* mask = SDAlertMaskWith(currentController, userView);
[mask userViewDidLoad:^(SDMaskModel<UserView*> * model) {
    model.    setAutolayoutValueForKey(@(0), @"bottom").    setAutolayoutValueForKey(@(15), @"left").    setAutolayoutValueForKey(@(15), @"right").    setAutolayoutValueForKey(@(350), @"height");
}];
[mask bindEventForControls:@[okButton, helpButton, [deleteButton sdm_withBindingKey:@"del"], ...]];
[mask bindEventForCancelControl:cancelButton];
[mask bindingEventFor:okButton usingBlock:^(SDMaskBindingEvent<UserView*> * event) {    /// ...}];
[mask bindingEventFor:@"del" usingBlock:^(SDMaskBindingEvent<UserView*> * event) {    /// ...}];
[mask show];

链式编程 Chain programming

• 链式编程涵盖了大多数方法 Chained programming covers most methods

[...[[[mask bindEventForControls:@[okButton]] bindEventForCancelControl:cancelButton] bindingEventsUsingBlock:^(SDMaskBindingEvent<UserView*>* event) {
    
}]... show];

Use autolayout

自动布局的两种方式 Tow ways to use autolayout.

• a. 框架提供 Use the methods provided by the SDMask to use autolayout.

[mask userViewDidLoad:^(SDMaskModel<UserView*> * model) {
    model.    setAutolayoutValueForKey(@(0), @"bottom").    setAutolayoutValueForKey(@(15), @"left").    setAutolayoutValueForKey(@(15), @"right").    setAutolayoutValueForKey(@(350), @"height");
}];

• b. 三方或手动布局 Autolayout by youself. Like 'masonry'

[mask userViewDidLoad:^(SDMaskModel<UserView*> * model) {
    [model.userView mas_makeConstraints:^(MASConstraintMaker *make) {
        make.center.equalTo(model.containerView);
        make.left.equalTo(model.containerView.mas_left).offset(20);
        make.right.equalTo(model.containerView.mas_right).offset(-20);
    }];
}];

自定义动画 Use custom animations

• Framelayout

[[[[[mask userViewPresentationWillAnimate:^(SDMaskModel<UserView*> * model) {
    userView.frame = frameA;
}] userViewPresentationDoAnimations:^(SDMaskModel<UserView*> * model) {
    userView.frame = frameB;
}] userViewDismissionWillAnimate:^(SDMaskModel<UserView*> * model) {    /// ...}] userViewDismissionDoAnimations:^(SDMaskModel<UserView*> * model) {
    userView.frame = frameA;
}] disableSystemAnimation];

• Autolayout

[[[[[mask userViewPresentationWillAnimate:^(SDMaskModel<UserView*> * model) {
    userView.bottonConstraint = A;    //[self.view setNeedsLayout];
    //[self.view layoutIfNeeded];}] userViewPresentationDoAnimations:^(SDMaskModel<UserView*> * model) {
    userView.bottonConstraint = B;
    [self.view setNeedsLayout];
    [self.view layoutIfNeeded];
}] userViewDismissionWillAnimate:^(SDMaskModel<UserView*> * model) {    /// ...}] userViewDismissionDoAnimations:^(SDMaskModel<UserView*> * model) {
    userView.bottonConstraint = A;
    [self.view setNeedsLayout];
    [self.view layoutIfNeeded];
}] disableSystemAnimation];

block对泛型的支持 Block support for generics

• Avoid type declarations and weak declarations.
