创建一个视图,先在文件检查器里去掉自动布局选项。然后调整视图尺寸到3.5
UIView的作用是布局,渲染,分发事件。
常用到的视图控制器是
UIViewController
UINavigationController
UITabBarController
UITableViewController
//
// AppDelegate.m
// WX_01_controller

//
#import "AppDelegate.h"
#import "RootViewController.h"
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindowalloc] initWithFrame:[[UIScreenmainScreen] bounds]];
// Override point for customization after application launch.
self.window.backgroundColor = [UIColorwhiteColor];
[self.windowmakeKeyAndVisible];
UIViewController *rootViewController = [[UIViewController alloc] init];
rootViewController.view.backgroundColor = [UIColor redColor];
self.window.rootViewController = rootViewController;
// 将视图控制器添加到UIWindow上面去
// 代码创建ViewController和view
/*
UIViewController *rootViewController = [[RootViewController alloc] init];
rootViewController.view.backgroundColor = [UIColor redColor];
self.window.rootViewController = rootViewController;
*/
// nib创建
/*
UIViewController *rootViewController = [[RootViewController alloc] initWithNibName:@"View" bundle:nil];
self.window.rootViewController = rootViewController;
*/
// 如果没有指定View就找和控制器同名的View。先设置RootViewController这个View的自定义Class.如果设定的是一个控制器对象,就可以把这个控制器对象里的View连接到这个视图。无论怎样都要在连接控制器里连接到这个视图才能运行。
/*
UIViewController *rootViewController = [[RootViewController alloc] init];
self.window.rootViewController = rootViewController;
*/
// 之前代码设置view
//[self.window addSubview:rootViewController.view]
returnYES;
}
- (void)applicationWillResignActive:(UIApplication *)application
{
// Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
// Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game.
}
- (void)applicationDidEnterBackground:(UIApplication *)application
{
// Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
// If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
}
- (void)applicationWillEnterForeground:(UIApplication *)application
{
// Called as part of the transition from the background to the inactive state; here you can undo many of the changes made on entering the background.
}
- (void)applicationDidBecomeActive:(UIApplication *)application
{
// Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
}
- (void)applicationWillTerminate:(UIApplication *)application
{
// Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
}
