Ios iphone中状态栏高度增加

您好，当我的应用程序正在运行时，状态栏高度会增加。此问题仅在ios8中出现，否则一切正常。所以请帮我解决这个问题。我是iPhone新手

You can trey this.

Status bar height is, indeed, equals 20.0f points except following cases:

status bar has been hidden with setStatusBarHidden:withAnimation: method and its height equals 0.0f points;
as @Anton here pointed out, during an incoming call outside of Phone application or during sound recording session status bar height equals 40.0f points.

[UIApplication sharedApplication].statusBarFrame.size.height

只有iOS 8，在iPhone 6或6 Plus中。将启动屏幕添加到项目中。添加新文件->用户界面->启动屏幕。然后在目标的常规字段中，在启动屏幕文件字段中选择它-667h@2x750X1334和iPhone6+默认值-667h@3x1241x2208在iOS 8和iPhone6上只能工作，启动屏幕始终是一个xib文件。此文件是默认的-667h@2x将被忽略。非常感谢@Onik。如果我使用launchscreen.xib并在iPhone6+中运行应用程序，那么UI组件的计算是错误的。我不明白为什么UI会放错位置？
