IOS初始化控制器的实现方法总结
一.ViewControllViewController方法
#import "AppDelegate.h"
#import "ViewController.h"
@interface AppDelegate ()
@property(nonatomic,strong) ViewController *viewController;
@end
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
//初始化控制器
self.viewController = [[ViewController alloc]init];
//初始化window
self.window =[[UIWindow alloc]initWithFrame:[UIScreen mainScreen].bounds];
//设置控制器
self.window.rootViewController = self.viewController;
return YES;
}
二 .ViewControllViewController 与 xib方法
#import "AppDelegate.h"
#import "XibViewControllViewController.h"
@interface AppDelegate ()
@property(nonatomic,strong) ViewController *viewController;
@property(nonatomic,strong) XibViewControllViewController *xibControllViewController;
@end
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
//初始化控制器
self.xibControllViewController = [[XibViewControllViewController alloc]initWithNibName:@"XibViewControllViewController" bundle:nil];
//初始化window
self.window =[[UIWindow alloc]initWithFrame:[UIScreen mainScreen].bounds];
//设置控制器
self.window.rootViewController = self.xibControllViewController;
return YES;
}
