前言
弹出框组件应该是绝大多数应用都少不了的(只有极少数精心设计的APP会用不到) 当然我们的APP也不例外 之前我们APP的弹出框组件是我用pop写的 可是后来发现与系统原生动画有些冲突(pop内部用到了CATransaction 导致跟系统动画同时发生时会有问题) 所以上周花了大半天时间重写了一下MMPopupView这个组件
因为新写的组件完全是用Masonry写的 我觉得是个非常好的示例教程 结合之前我写的Masonry入门教程 应该可以更好的理解和运用Masonry/Autolayout 所以我又花了一点时间重新整理成了一个简单的开源库 有兴趣的朋友可以研究一下
运行的demo可以在这里查看
介绍
整体的组成大概就是这个样子
MMPopupWindow就是用来显示所有弹出框的容器 相对直接显示在当前UIWindow上来说 弄个独立的Window出来当容器的会更好
MMPopupView就是弹出框的基类 所有的弹出框只要继承自这个类 就具备了显示的能力 用户只要关注于弹出框本身的表现就行了
MMAlertView和MMSheetView都是我提供的基于MMPopupView的简单组件 可以直接拿来用 而且都是高度可定制的(这个稍后会介绍)
MMPopupWindow
MMPopupWindow的定义如下
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
@interface MMPopupWindow : UIWindow @property (nonatomic, assign) BOOL touchWildToHide; // default is NO. When YES, popup views will be hidden when user touch the translucent background. + (MMPopupWindow *)sharedWindow; /** * cache the window to prevent the lag of the first showing. */ - (void) cacheWindow; /** * show the translucent background */ - (void) showDimBackground; /** * hide the translucent background */ - (void) hideDimBackground; |
很简单 只有一个属性touchWildToHide用来控制是否可以点击非弹出框的地方来使弹出框消失 还有一个cacheWindow的方法来预加载MMPopupWindow 防止第一次使用的时候顿卡
另外还有两个用于显示和隐藏背景色的方法 这个在自定义动画的时候会用到
1 2 3 |
- (void) showDimBackground; - (void) hideDimBackground;
|
MMPopupView
MMPopupView的定义如下
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 |
typedef NS_ENUM(NSUInteger, MMPopupType) { MMPopupTypeAlert, MMPopupTypeSheet, MMPopupTypeCustom, }; @class MMPopupView; typedef void(^MMPopupBlock)(MMPopupView *); @interface MMPopupView : UIView @property (nonatomic, assign) MMPopupType type; // default is MMPopupTypeAlert. @property (nonatomic, assign) NSTimeInterval animationDuration; // default is 0.3 sec. @property (nonatomic, assign) BOOL withKeyboard; // default is NO. When YES, alert view with be shown with a center offset (only effect with MMPopupTypeAlert). @property (nonatomic, copy ) MMPopupBlock showCompletionBlock; // show completion block. @property (nonatomic, copy ) MMPopupBlock hideCompletionBlock; // hide completion block @property (nonatomic, copy ) MMPopupBlock showAnimation; // custom show animation block (only effect with MMPopupTypeCustom). @property (nonatomic, copy ) MMPopupBlock hideAnimation; // custom hide animation block (only effect with MMPopupTypeCustom). /** * override this method to show the keyboard if with a keyboard */ - (void) showKeyboard; /** * override this method to hide the keyboard if with a keyboard */ - (void) hideKeyboard; /** * show the popup view */ - (void) show; /** * show the popup view with completiom block * * @param block show completion block */ - (void) showWithBlock:(MMPopupBlock)block; /** * hide the popup view */ - (void) hide; /** * hide the popup view with completiom block * * @param block hide completion block */ - (void) hideWithBlock:(MMPopupBlock)block; @end |
使用起来很简单 定义好自己的view 然后调用下面的方法就好了
1 2 |
- (void) show; - (void) hide; |
默认提供了三种类型 对应三种动画效果
1 2 3 4 5 |
typedef NS_ENUM(NSUInteger, MMPopupType) { MMPopupTypeAlert, //中间隐出 MMPopupTypeSheet, //向上滑出 MMPopupTypeCustom, //向下掉落 }; |
当然你也可以自己定义想要的动画效果 只要重载下面两个block就行了
1 2 |
@property (nonatomic, copy) MMPopupBlock showAnimation; @property (nonatomic, copy) MMPopupBlock hideAnimation; |
同时提供了动画的回调 可以直接指定block或者直接调用方法
1 2 3 4 5 |
@property (nonatomic, copy ) MMPopupBlock showCompletionBlock; @property (nonatomic, copy ) MMPopupBlock hideCompletionBlock; - (void) showWithBlock:(MMPopupBlock)block; - (void) hideWithBlock:(MMPopupBlock)block;
|
MMAlertView
MMAlertView就是UIAlertView的替代品 接口如下
1 2 3 4 5 6 7 8 9 10 11 12 13 |
typedef void(^MMPopupInputHandler)(NSString *text); @interface MMAlertView : MMPopupView @property (nonatomic, assign) NSUInteger maxInputLength; // default is 0. Means no length limit. - (instancetype) initWithInputTitle:(NSString*)title detail:(NSString*)detail placeholder:(NSString*)inputPlaceholder handler:(MMPopupInputHandler)inputHandler; - (instancetype) initWithConfirmTitle:(NSString*)title detail:(NSString*)detail; - (instancetype) initWithTitle:(NSString*)title detail:(NSString*)detail items:(NSArray*)items; @end |
分别对应下面三种形式
同时提供一个全局的配置类 可以充分的自定义
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 |
@interface MMAlertViewConfig : NSObject + (MMAlertViewConfig*) globalConfig; @property (nonatomic, assign) CGFloat width; // Default is 275. @property (nonatomic, assign) CGFloat buttonHeight; // Default is 50. @property (nonatomic, assign) CGFloat innerMargin; // Default is 25. @property (nonatomic, assign) CGFloat cornerRadius; // Default is 5. @property (nonatomic, assign) CGFloat titleFontSize; // Default is 18. @property (nonatomic, assign) CGFloat detailFontSize; // Default is 14. @property (nonatomic, assign) CGFloat buttonFontSize; // Default is 17. @property (nonatomic, strong) UIColor *backgroundColor; // Default is #FFFFFF. @property (nonatomic, strong) UIColor *titleColor; // Default is #333333. @property (nonatomic, strong) UIColor *detailColor; // Default is #333333. @property (nonatomic, strong) UIColor *splitColor; // Default is #CCCCCC. @property (nonatomic, strong) UIColor *itemNormalColor; // Default is #333333. effect with MMItemTypeNormal @property (nonatomic, strong) UIColor *itemHighlightColor; // Default is #E76153. effect with MMItemTypeHighlight @property (nonatomic, strong) UIColor *itemPressedColor; // Default is #EFEDE7. @property (nonatomic, strong) NSString *defaultTextOK; // Default is "好". @property (nonatomic, strong) NSString *defaultTextCancel; // Default is "取消". @property (nonatomic, strong) NSString *defaultTextConfirm; // Default is "确定". @end
|
MMAlertView
MMAlertView就是UIAlertView的替代品 接口如下
1 2 3 4 |
@interface MMSheetView : MMPopupView - (instancetype) initWithTitle:(NSString*)title items:(NSArray*)items; @end |
呈现如下
同时提供一个全局的配置类 可以充分的自定义
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
@interface MMSheetViewConfig : NSObject + (MMSheetViewConfig*) globalConfig; @property (nonatomic, assign) CGFloat buttonHeight; // Default is 50. @property (nonatomic, assign) CGFloat innerMargin; // Default is 19. @property (nonatomic, assign) CGFloat titleFontSize; // Default is 14. @property (nonatomic, assign) CGFloat buttonFontSize; // Default is 17. @property (nonatomic, strong) UIColor *backgroundColor; // Default is #FFFFFF. @property (nonatomic, strong) UIColor *titleColor; // Default is #666666. @property (nonatomic, strong) UIColor *splitColor; // Default is #CCCCCC. @property (nonatomic, strong) UIColor *itemNormalColor; // Default is #333333. effect with MMItemTypeNormal @property (nonatomic, strong) UIColor *itemDisableColor; // Default is #CCCCCC. effect with MMItemTypeDisabled @property (nonatomic, strong) UIColor *itemHighlightColor; // Default is #E76153. effect with MMItemTypeHighlight @property (nonatomic, strong) UIColor *itemPressedColor; // Default is #EFEDE7. @property (nonatomic, strong) NSString *defaultTextCancel; // Default is "取消" @end
|
MMPopupItem
MMPopupItem是用于MMAlertView和MMSheetView的动作对象(对应按钮) 定义如下
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 |
typedef void(^MMPopupItemHandler)(NSInteger index); @interface MMPopupItem : NSObject @property (nonatomic, assign) BOOL highlight; @property (nonatomic, assign) BOOL disabled; @property (nonatomic, strong) NSString *title; @property (nonatomic, strong) UIColor *color; @property (nonatomic, copy) MMPopupItemHandler handler; @end typedef NS_ENUM(NSUInteger, MMItemType) { MMItemTypeNormal, MMItemTypeHighlight, MMItemTypeDisabled }; NS_INLINE MMPopupItem* MMItemMake(NSString* title, MMItemType type, MMPopupItemHandler handler) { MMPopupItem *item = [MMPopupItem new]; item.title = title; item.handler = handler; switch (type) { case MMItemTypeNormal: { break; } case MMItemTypeHighlight: { item.highlight = YES; break; } case MMItemTypeDisabled: { item.disabled = YES; break; } default: break; } return item; } |
使用方式如下
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 |
//MMAlertView NSArray *items = @[MMItemMake(@"Done", MMItemTypeNormal, block), MMItemMake(@"Save", MMItemTypeHighlight, block), MMItemMake(@"Cancel", MMItemTypeNormal, block)]; [[[MMAlertView alloc] initWithTitle:@"AlertView" detail:@"each button take one row if there are more than 2 items" items:items] showWithBlock:completeBlock]; //MMSheetView NSArray *items = @[MMItemMake(@"Normal", MMItemTypeNormal, block), MMItemMake(@"Highlight", MMItemTypeHighlight, block), MMItemMake(@"Disabled", MMItemTypeDisabled, block)]; [[[MMSheetView alloc] initWithTitle:@"SheetView" items:items] showWithBlock:completeBlock]; |
自定义
除了使用MMAlertView和MMSheetView之外 比如我们的应用中会用到输入验证码的提示框和日期的选择框 都可以用MMPopupView来轻松实现
