Xcode6 下实现界面切换
Xcode6 下实现界面切换
1.新建一个工程T Xcode ——> File——>New--->Project--->Single View Application
2. 添加一个三个Cocoa Touch Class 基类为UIViewController类,SwitchViewController、FirstViewController、SecondViewController。
3.在storyBoard中创建两个View Controller,分别设置Storyboard ID为first 和 second，Class为FIrstViewController 和 SecondViewController。并在界面上各放一个label和button
4.对类进行修改
1.在AppDelegate.h文件中，添加
@class SwitchViewController;
@property (nonatomic,retain)IBOutlet SwitchViewController* switchViewCOntroller;
+(AppDelegate*) app;
2.在AppDelegate.m文件中添加，
#import "SwitchViewController.h"
修改didFinishLaunchingWithOptions函数
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
self.switchViewCOntroller=[[SwitchViewControlleralloc]init];
[self.switchViewCOntrollerinitView];
self.window.rootViewController=self.switchViewCOntroller;
self.window.backgroundColor=[UIColorwhiteColor];
[self.windowmakeKeyAndVisible];
returnYES;
}
+(AppDelegate*) app{
return (AppDelegate *) [[UIApplicationsharedApplication] delegate];
}
3.修改SwitchViewCOntroller类
1.头文件修改成
#import
@class FirstViewController;
@class SecondViewController;
@interface SwitchViewController :UIViewController{
FirstViewController* firstViewController;
SecondViewController* secondViewController;
}
@property(nonatomic ,retain)FirstViewController* firstViewController;
@property(nonatomic ,retain)SecondViewController* secondViewController;
-(void) initView;
-(void) showFirstView;
-(void) showSecondView;
-(void) removeAllView;
@end
2.m文件中完成添加的方法。
#import "FirstViewController.h"
#import "SecondViewController.h"
-(void) initView{
if (self.firstViewController ==nil) {
UIStoryboard *futureStoryBoard = [UIStoryboardstoryboardWithName:@"Main"bundle:nil];
self.firstViewController = [futureStoryBoardinstantiateViewControllerWithIdentifier:@"first"];
}
[selfremoveAllView];
[self.viewinsertSubview:self.firstViewController.viewatIndex:0];
}
-(void) showFirstView{
if (self.firstViewController ==nil) {
UIStoryboard *futureStoryBoard = [UIStoryboardstoryboardWithName:@"Main"bundle:nil];
self.firstViewController = [futureStoryBoardinstantiateViewControllerWithIdentifier:@"first"];
}
[selfremoveAllView];
[self.viewinsertSubview:self.firstViewController.viewatIndex:0];
}
-(void) showSecondView{
if (self.secondViewController ==nil) {
UIStoryboard *futureStoryBoard = [UIStoryboardstoryboardWithName:@"Main"bundle:nil];
self.secondViewController = [futureStoryBoardinstantiateViewControllerWithIdentifier:@"second"];
}
[selfremoveAllView];
[self.viewinsertSubview:self.secondViewController.viewatIndex:0];
}
-(void) removeAllView{
int t=[self.view.subviewscount];
NSLog(@"%d",t);
for (int i=0;i<[self.view.subviewscount];i++) {
[[self.view.subviewsobjectAtIndex:i] removeFromSuperview];
}
}
5.为两个界面上的按钮分别添加消息响应函数
firstViewController添加
- (IBAction)buttonClick:(id)sender {
[[AppDelegateapp].switchViewCOntroller showSecondView];
}
secondViewController添加- (IBAction)buttonClick:(id)sender {
[[AppDelegateapp].switchViewCOntroller showFirstView];
}
