大家好，我想问问你们中是否有人遇到过像我这样的问题。我一直在使用 Three20 框架的 TTNavigator 做一个项目。每个视图都按应有的方式显示和转换。我有一个应用程序菜单，其中包含应用程序各自模块的按钮。问题是，当我单击特定模块的按钮并显示该视图时，TTNavigator 的 URL 属性值是应用程序的菜单视图 (tt://mainMenu) 而不是模块的初始视图 (例如“tt://messageBoard”或“tt://profilePage”）。我已经检查并审查了可能与此问题相关的必要代码块，但我似乎无法解决手头的错误。

这是我的 AppDelegate 的定义

#import "Three20TestAppDelegate.h"
#import "StartViewController.h"
#import "JumpsiteProfilePage.h"
#import "MenuViewController.h"
#import "BNDefaultStylesheet.h"
#import "MessageBoardViewController.h"
#import "GroupListViewController.h"
#import "DrillDownGroupListView.h"
#import "ProfileListViewController.h"
#import "ProfileDetailsViewController.h"

#define UIColorFromRGB(rgbValue) [UIColor \
colorWithRed:((float)((rgbValue & 0xFF0000) >> 16))/255.0 \
green:((float)((rgbValue & 0xFF00) >> 8))/255.0 \
blue:((float)(rgbValue & 0xFF))/255.0 alpha:1.0]

@implementation UINavigationBar (UINavigationBarCategory)
-(void)drawRect:(CGRect)rect{

UIImage *image = [UIImage imageNamed:@"NavBar BG.png"];
[image drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)];

self.tintColor = UIColorFromRGB(0xFFD900);

}
@end

@implementation UIToolbar (UIToolbarCategory)
-(void)drawRect:(CGRect)rect{

UIImage *image = [UIImage imageNamed:@"NavBar BG.png"];
[image drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)];

self.tintColor = UIColorFromRGB(0xFFD900);
[super drawRect:rect];
}



@end

映射视图控制器

[map from:kAppRootURLPath toViewController:[HomeThumbnailViewController class]];

调用 ViewController

TTURLAction *urlAction=[[[TTURLAction alloc] initWithURLPath:strTTURL] autorelease];
urlAction.animated=YES;
[[TTNavigator navigator]openURLAction:urlAction];
