在沒有安裝顯卡驅動的雪豹下開發真是痛苦!
悲劇的thinkpad。。。所以不能截圖。。。稀爛！
1. 創建一個viewcontroller，比如SettingViewController，同時創建實現文件和頭文件，不多說
2. 創建該viewcontroller對應的view文件，比如SettingView.xib，沒什么好說的
3. 雙擊剛才創建的xib文件，指定class為第一步創建的viewcontroller，在interface builder中將view和file owner連接起來
4. 在創建的SettingViewController.h文件中定義一個bool類型的變量，該變量用來指示modal view是否已彈出，代碼如下：
@interface SettingViewController : UIViewController {
BOOL isPushedView;
}
@property (nonatomic, readwrite) BOOL isPushedView;
5. 在SettingViewController.m文件中添加具體實現代碼，如下：
@implementation SettingViewController
@synthesize isPushedView;
- (void)viewDidLoad {
[super viewDidLoad];
if(isPushedView == NO) {
self.navigationItem.title = @"設置";
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文件中定義變量，代碼如下:
@class SettingViewController;
@interface RootViewController : UITableViewController {
SettingViewController *settingViewController;
UINavigationController *settingNavController;
}
7. 在RootViewController.m文件中添加實現代碼，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!!!
