為iPad或者iPhone大屏幕進行適配分屏顯示，蘋果提供了UISplitViewController這個容器熟丸。
關(guān)鍵參數(shù)介紹
preferredDisplayMode
UISplitViewControllerDisplayModeAutomatic, 自動,默認樣式
UISplitViewControllerDisplayModePrimaryHidden, 主視圖隱藏 橫豎屏主視圖都會隱藏,可以通過手勢來控制主視圖的顯隱
UISplitViewControllerDisplayModeAllVisible, 始終顯示 橫豎屏主視圖都會顯示,不可以通過手勢來控制主視圖的顯隱
UISplitViewControllerDisplayModePrimaryOverlay, 主視圖懸停 橫豎屏主視圖都會顯示,可以通過手勢來控制主視圖的顯隱
-
preferredPrimaryColumnWidthFraction
主視圖的寬度比例:主視圖的寬度比例 = 主視圖寬度 / SplitViewController整體寬度 -
maximumPrimaryColumnWidth
主視圖的寬度最大值 -
minimumPrimaryColumnWidth
主視圖的寬度最小值
主視圖的寬度比例不好控制告组，并且受最大值
maximumPrimaryColumnWidth和最小值minimumPrimaryColumnWidth兩個屬性限制
簡單實用
在AppDelegate中初始化代碼
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
UISplitViewController *vc = [[UISplitViewController alloc] init];
vc.preferredDisplayMode = UISplitViewControllerDisplayModeAllVisible;
// 主控制
UINavigationController *master = [[UINavigationController alloc] initWithRootViewController:[[MasterViewController alloc] init]];
// 內(nèi)容顯示控制器
UINavigationController *content = [[UINavigationController alloc] initWithRootViewController:[[ContentViewController alloc] init]];
vc.viewControllers = @[master, content];
self.window.rootViewController = vc;
[self.window makeKeyAndVisible];
return YES;
}
主控制器中
