Ios UIView幻灯片过渡,需要帮助&;近工作代码
我希望以完全编程的方式完成以下工作,并且有一些代码几乎可以做到这一点 目标Ios UIView幻灯片过渡,需要帮助&;近工作代码,ios,swift,uiview,subview,animatewithduration,Ios,Swift,Uiview,Subview,Animatewithduration,我希望以完全编程的方式完成以下工作,并且有一些代码几乎可以做到这一点 目标 两个主视图之间的转换,viewOne和viewTwoviewOne'是初始全屏视图 具有不同方向和类型的滑块的过渡 a。专门使用左/右或上/下 b。能够选择方向(例如“向上”或“向下”) 观察到的代码响应 [Good]下面的代码成功地在视图之间转换 [问题]下面的代码只使用相同的转换,每次左->右 核心代码 (其余代码段在下面第二个区块中发布) 剩余代码段 回想一下,这是100%编程的。因此,我觉得这里的代码非常有价值,
解决了!谢谢你,扎克B 以下是对解决方案的原始代码所做的关键更改
- (转换类型)UIViewAnimationOptions.TransitionCrossBluse用于“选项:”
- (过渡方向)由视图的初始屏幕外位置设置!有关清晰的示例,请参见拾取视图()中的X删除

}你不应该把问题的某些部分作为答案发布,因为它肯定不是答案。Losiowaty,那么你的建议是什么:)?我认为在核心问题中贴出所有这些“垃圾”是丑陋和卑鄙的意思。在我看来,当前的post方法更干净!:)你的问题到底是什么?您尝试了哪些不同的滑动方向?代码中只有一个“问题”-动画选项(即
TransitionCurlUp
或TransitionFlipFromLeft
)仅在使用方法时使用。我将“UIView.animateWithDuration”(UIView.animateWithDuration)更改为“UIView.transitionWithView()”,但它仍然不可修改!代码现在做了一个不同的动画,从屏幕外扩展到新视图。还要注意的是,我已经尝试过diff动画-取消注释'animationType'并尝试:)!对于这个问题,如您所问,请参阅“观察到的代码响应->[问题]”…:)
