我一直在尝试新的iOS 7自定义转换API,并查看了我能找到的所有教程/文档,但我似乎无法根据我的具体情况来计算这些内容.
基本上我正在尝试实现的是一个视图上的UIPanGestureRecognizer,我将向上滑动并转换到VC,其视图将从底部向上滑动,而当我将手指向上移动时当前视图将向上滑动.
没有交互转换我没有遇到任何问题,但是一旦我实现了交互(平移手势),我似乎无法完成转换.
这是来自VC的相关代码,它符合出售动画控制器所需的UIViewControllerTransitionDelegate:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([segue.identifier isEqualToString:@"Swipe"]) {
NSLog(@"PREPARE FOR SEGUE METHOD CALLED");
UIViewController *toVC = segue.destinationViewController;
[interactionController wireToViewController:toVC];
toVC.transitioningDelegate = self;
toVC.modalPresentationStyle = UIModalPresentationCustom;
}
}

这是一种明显的,我们都会同意,我们可以称之为HDFS + YARN + MapReduce是Hadoop的.但是,Hadoop生态系统中不同的其他组合和其他产品会发生什么?
例如,HDFS + YARN + Spark仍然是Hadoop?是HBASE Hadoop吗?我想我们考虑HDFS + YARN + Pig Hadoop,因为Pig使用MapReduce.
只有MapReduce工具被认为是Hadoop,但其他任何运行的东西HDFS + YARN(如Spark)都是非Hadoop吗?
我想知道Snips NLU和Rasa NLU之间的区别吗?哪个更简单有力?
我想知道为什么一个未使用的变量是坏的.
是因为编译器会创建一个更大的二进制文件吗?如果是,是否有可以添加unused关键字或类似内容的工具/脚本?
我有一个UISplitViewController主控制器和细节控制器:
MyMasterController *masterViewController = [[[MyMasterController alloc] initWithDirectory:directoryElement] autorelease];

UISplitViewController *splitViewController = [[UISplitViewController alloc] init];

我遇到了collectionView项目大小的问题.我想在纵向模式中显示3个项目,在横向模式下显示6个项目.我已经设置了像这样的-layoutSubviews:
- (void)layoutSubviews {
[super layoutSubviews];
if ([[UIApplication sharedApplication] statusBarOrientation] == UIInterfaceOrientationPortrait || ([[UIApplication sharedApplication] statusBarOrientation] == UIInterfaceOrientationPortraitUpsideDown)) {
//Portrait orientation
self.flowLayoutPortrait.itemSize = CGSizeMake(106, 106);
} else if ([[UIApplication sharedApplication] statusBarOrientation] == UIInterfaceOrientationLandscapeLeft || ([[UIApplication sharedApplication] statusBarOrientation] == UIInterfaceOrientationLandscapeRight)) {
//Landscape orientation
self.flowLayoutPortrait.itemSize = CGSizeMake(93, 93);
}
[self.collectionView.collectionViewLayout invalidateLayout];
}

但是单元格大小不会更新,它对于两个方向始终保持不变.如果我创建2个flowLayouts并使用:
[self.collectionView setCollectionViewLayout:self.flowLayoutLandscape];

一切正常,但我真的不喜欢它们是如何改变的.动画真的很糟糕.而且因为itemSize是唯一需要更新的属性,所以使用1布局似乎是最佳选择.
如何告诉collectionView更新布局?
我目前正在使用"Regions"示例代码:https: //developer.apple.com/library/ios/#samplecode/Regions/Introduction/Intro.h tml#// apple_ref/doc/uid/DTS40010726-Intro-DontLinkElementID_2
我想更进一步,当用户退出该区域时生成或触发通知(可以同时进入和退出,我不介意,对于初始实现最简单的事情).
我一直在查看CLLocation类参考,位置感知编程指南以及本地和推送通知编程指南.而我正在遭受信息超载.
非常感谢 :)
编辑:我想我可能有一个解决问题的想法:在RegionsViewController实现文件中有这样的:
- (void)locationManager:(CLLocationManager *)manager didExitRegion:(CLRegion *)region {
NSString *event = [NSString stringWithFormat:@"didExitRegion %@ at %@", region.identifier, [NSDate date]];
[self updateWithEvent:event];
}

由于我想在用户退出指定区域边界时实现本地通知,我输入了以下内容:

它只是初始化并显示Mother Class它的IB对象.我理解为什么,但我开始认为不可能做我想做的事.有什么建议吗?

我会像我那样使用我的SonViewController:
