IOS UITableViewCells在第一个小区,Iphone5S设备中都混乱,64位模拟器

我有一个表现奇怪的UITableView.具体来说,它在cellForRowAtIndexPath中生成了一个常数8个单元格,带有一些基本文本和图像.在模拟器中它很棒.在我的 Iphone5上,它的工作方式与模拟器完全相同,但是在我的Iphone5s上,单元格在第一个单元格应该存在的地方互相混淆.下面的图像分别显示5s和模拟器/ 5.左侧“退出应用程序”按钮应存在于最后一个单元格中,并且正在添加到其他内容之上,也由箭头指示.

编辑：第三个图像是64位模拟器,更新的cellForRowAtIndexPath是超简化的,只需将textLabel设置为所有8行的“Hello”.

Autolayout未在应用程序的任何位置使用.

Iphone 5S正在运行IOS7.1.1,但Iphone5正在运行IOS7.1.模拟器是最新Xcode(5.1.1)的一部分,最新的7.1.我无法想象5s的最新.1可能会导致这种情况.

有什么想法为什么这是混乱的,具体为什么只有在5S？

解决方法

返回CGFloat,而不是从heightForRow方法浮动.这是一个64位问题 – 类型在那里定义不同.我认为返回一个浮点值会导致64位设备中的高度被视为零.

您需要更改方法的返回类型以及其中的声明.不要使用浮动UIKit的东西,它总是CGFloat.
