本文提供了一段Objective-C代码片段，用于在iOS应用中根据屏幕尺寸动态调整导航栏和状态栏的高度，进而调整视图的布局。通过判断设备型号，设置合适的窗口高度，最终实现导航栏与状态栏的隐藏或显示，确保应用界面在不同设备上的一致性和美观性。

- (void)hideTabbar:(BOOL)hidden {

// CGRect windowFrame = iPhone5 ? CGRectMake(0.0f, 0.0f, 320.0f, 568.0f) : CGRectMake(0.0f, 0.0f, 320.0f, 480.0f);

CGRect windowFrame=[[UIScreenmainScreen]bounds ];

// CGRect windowFrame = CGRectMake(0.0f, 0.0f, 768.0f, 1024.0f);

float windowHeight = windowFrame.size.height;

if(hidden) {

CGRect newFrame = windowFrame;

newFrame.size.height -=navHeight + statusBarHeight;

self.view.frame = newFrame;

}

else {

CGRect newFrame = windowFrame;

newFrame.size.height -=tabBarHeight + navHeight +statusBarHeight;

self.view.frame = newFrame;

}

viewWidth =self.view.frame.size.width;

viewHeight =self.view.frame.size.height;

[UIViewbeginAnimations:nilcontext:NULL];

[UIViewsetAnimationDuration:0];

//这个位子给大家注视一下，获取self.tabBarC中的UItabBar在对其进行隐藏操作

for(UIView *viewin self.tabBarController.view.subviews){

if([view isKindOfClass:[UITabBar class]]){

if (hidden) {

[viewsetFrame:CGRectMake(view.frame.origin.x, windowHeight, view.frame.size.width, view.frame.size.height)];

}else {

[viewsetFrame:CGRectMake(view.frame.origin.x, windowHeight -tabBarHeight, view.frame.size.width, view.frame.size.height)];

}

}else{

if (hidden) {

[viewsetFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, windowHeight)];

}else {

[viewsetFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, windowHeight -tabBarHeight)];

}

[UIViewcommitAnimations];

}
