IOS初始化控制器的实现方法总结

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;
}
