在没有安装显卡驱动的雪豹下开发真是痛苦!
悲剧的thinkpad。。。所以不能截图。。。稀烂！
1. 创建一个viewcontroller，比如SettingViewController，同时创建实现文件和头文件，不多说
2. 创建该viewcontroller对应的view文件，比如SettingView.xib，没什么好说的
3. 双击刚才创建的xib文件，指定class为第一步创建的viewcontroller，在interface builder中将view和file owner连接起来
4. 在创建的SettingViewController.h文件中定义一个bool类型的变量，该变量用来指示modal view是否已弹出，代码如下：
@interface SettingViewController : UIViewController {
BOOL isPushedView;
}
@property (nonatomic, readwrite) BOOL isPushedView;
5. 在SettingViewController.m文件中添加具体实现代码，如下：
@implementation SettingViewController
@synthesize isPushedView;
- (void)viewDidLoad {
[super viewDidLoad];
if(isPushedView == NO) {
self.navigationItem.title = @"设置";
self.navigationController.navigationBar.barStyle = UIBarStyleBlack;
self.navigationItem.leftBarButtonItem = [[[UIBarButtonItem alloc] initWithTitle:@"完成" style:UIBarButtonItemStylePlain target:self action:@selector(cancel_Clicked:)] autorelease];
}
}
-(void) cancel_Clicked:(id)sender {
[self.navigationController dismissModalViewControllerAnimated:YES];
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
6. 在RootViewController.h文件中定义变量，代码如下:
@class SettingViewController;
@interface RootViewController : UITableViewController {
SettingViewController *settingViewController;
UINavigationController *settingNavController;
}
7. 在RootViewController.m文件中添加实现代码，如下：
- (void) settingClicked {
if(settingViewController == nil) {
settingViewController = [[SettingViewController alloc] initWithNibName:@"SettingView" bundle:[NSBundle mainBundle]];
settingViewController.isPushedView = NO;
}
if(settingNavController == nil) {
settingNavController = [[UINavigationController alloc] initWithRootViewController:settingViewController];
[self.navigationController presentModalViewController:settingNavController animated:YES];
}
}
8. DONE!!!
