WYPopoverAnimator

动画弹窗，方便灵活，达到给控制器瘦身的效果

如何使用WYPopoverAnimator

• 手动导入:
  • 将Animation整个文件夹拖入到项目中
  • 导入头文件: #import "WYPopoverAnimator.h"

在代码中如何使用:

/// 转场动画代理
@property (nonatomic, strong) WYPopoverAnimator *popAnimator;

#pragma mark - 懒加载
- (WYPopoverAnimator *)popAnimator {
    if (_popAnimator == nil) {
        _popAnimator = [[WYPopoverAnimator alloc] init];
    }
    return _popAnimator;
}

在弹出控制器的地方编写代码:

    /// modal出一个新的控制器
    UIViewController *controller = [[UIViewController alloc] init];
    controller.transitioningDelegate = self.popAnimator;
    // 设置弹出控制器的大小
    self.popAnimator.presentFrame = CGRectMake(100, 56, 200, 300);
    // 设置遮罩背景颜色
    self.popAnimator.dummyColor = [UIColor colorWithWhite:0.5 alpha:0.7];
    // 设置动画的类型
    self.popAnimator.type = WYPopoverAnimatorTypeDown;
    // 设置modal的展示样式
    controller.modalPresentationStyle = UIModalPresentationCustom;
    
    [self presentViewController:controller animated:YES completion:nil];

具体动画控制样式可参考WYPopoverAnimator.h

typedef enum {
    WYPopoverAnimatorTypeDown,   // 由上往下
    WYPopoverAnimatorTypeBounds, // 从中间开始逐渐变到屏幕大小
    WYPopoverAnimatorTypeFateIn  // 淡入淡出
}WYPopoverAnimatorType;

@interface WYPopoverAnimator : NSObject <UIViewControllerTransitioningDelegate, UIViewControllerAnimatedTransitioning>

/// model出来的控制器的frame
@property (nonatomic, assign) CGRect presentFrame;
/// 遮罩视图颜色
@property (nonatomic, strong) UIColor *dummyColor;
/// modal出动画的类型
@property (nonatomic, assign) WYPopoverAnimatorType type;
