前言
在开发过程中虽然 UI 这个活很没技术含量,但有时候还是需要做些的特别的转场效果.本教程参考UIPresentationController Tutorial: Getting Started 这篇博文进行 OC 版翻译 也加入了一些小改动
需求背景
转场对目前的 iOS 来讲已经不能再熟悉了 但想找个靠谱点的带遮盖的转场 没找到几个靠谱的
不是这个问题不行就那个问题不能满足
根据Raywenderrich的教程 我翻译成了 OC 版本 并加了一些小改动
如何使用
- 导入头文件
1
2
#import "SlideInPresentationManager.h"
- 声明属性
1
@property (nonatomic, strong) SlideInPresentationManager *slideInTransitioningDelegate;
- 弹出模态控制器的时候如下代码

- (IBAction)presentAction:(UIButton *)sender {
PresentationDirection direction;
if (sender.tag == 100) {
NSLog(@"左侧弹出模态转场");
direction = PresentationDirectionLeft;
} else if (sender.tag == 101) {
NSLog(@"上弹出模态转场");
direction = PresentationDirectionTop;
} else if (sender.tag == 102) {
NSLog(@"右弹出模态转场");
direction = PresentationDirectionRight;
} else {
NSLog(@"下弹出模态转场");
direction = PresentationDirectionBottom;
}
self.slideInTransitioningDelegate = nil;
//控制现实遮盖的视图转场(core 代码)
self.slideInTransitioningDelegate = [[SlideInPresentationManager alloc] init];
self.slideInTransitioningDelegate.direction = direction;
self.slideInTransitioningDelegate.disableCompactHeight = NO;
self.slideInTransitioningDelegate.sliderRate = 1.0/3.0;
//创建控制器实例
PresentController *presentVC = [[PresentController alloc] initWithNibName:@"PresentController" bundle:[NSBundle mainBundle]];
presentVC.transitioningDelegate = self.slideInTransitioningDelegate;
presentVC.modalPresentationStyle = UIModalPresentationCustom;
[self presentViewController:presentVC animated:YES completion:nil];
}
剩下的就可以愉快的玩耍了
