新建了一个single view application的工程，添加了4个其它的view，想做到在这几个view窗口中自由切换，不知道能不能实现，还是新手，请教大家了
每个窗口中5个按钮，这样方便切换到其它的视图
#import <UIKit/UIKit.h>
#import "FirstViewController.h"
#import "SecondViewController.h"
#import "ThirdViewController.h"
#import "FourViewController.h"
@interface ViewController : UIViewController
- (IBAction)gotoFirstView:(id)sender;
- (IBAction)gotoSceondView:(id)sender;
- (IBAction)gotoThirdView:(id)sender;
- (IBAction)gotoFourView:(id)sender;
@property (retain, nonatomic) FirstViewController *firstViewController;
@property (retain, nonatomic) SecondViewController *secondViewController;
@property (retain, nonatomic) ThirdViewController *thirdViewController;
@property (retain, nonatomic) FourViewController *fourViewController;
@end
上面是主View中的代码
点击每个BUTTON以后的代码如下
- (IBAction)gotoFirstView:(id)sender {
if (self.firstViewController == nil) {
firstViewController = [[FirstViewController alloc]initWithNibName:@"FirstViewController" bundle:nil];
[self.view addSubview:firstViewController.view];
}else {
[self.view addSubview:firstViewController.view];//重新显示第一个窗口
}
}
- (IBAction)gotoSceondView:(id)sender {
if (self.secondViewController == nil) {
secondViewController = [[SecondViewController alloc]initWithNibName:@"SecondViewController" bundle:nil];
[self.view addSubview:secondViewController.view];
}
}
- (IBAction)gotoThirdView:(id)sender {
if (self.thirdViewController == nil) {
thirdViewController = [[ThirdViewController alloc]initWithNibName:@"ThirdViewController" bundle:nil];
[self.view addSubview:thirdViewController.view];
}
}
- (IBAction)gotoFourView:(id)sender {
if (self.fourViewController == nil) {
fourViewController = [[FourViewController alloc]initWithNibName:@"FourViewController" bundle:nil];
[self.view addSubview:fourViewController.view];
}
}
用这样的方式我能切换到其它的窗口
在FirstViewController中要切回主窗口我用以下代码
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
NSLog(@"FirstViewDisplay");
}
- (void) viewWillAppear:(BOOL)animated{
NSLog(@"FirstViewDisplay viewWillAppear");
}
- (void)viewDidUnload
{
[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
NSLog(@"FirstViewRemove");
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return YES;
}
- (IBAction)gotoMainView:(id)sender {//将第一个窗口移除
[self.view removeFromSuperview];
}
- (IBAction)gotoSecondView:(id)sender {
}
- (IBAction)gotoThirdView:(id)sender {
}
- (IBAction)gotoFourView:(id)sender {
}
这样我可以实现跟主FirstView跟主View的切换
第一次切换到FirstViewController的viewDidLoad函数会调用一下
有没有办法每次切换到FirstViewController窗口的时候有消息通知呢
还有就是切换回主View的时候也有消息通知，因为主View的viewDiidLoad也只会调用一次，以后再切换就不会调用
想实现这5个按钮VIEW间的相互切换，以及有消息通知，请教各位前辈了

我有一个例子，留下邮箱发给你，只实现了视图的切换，还没有传递消息
