我如何在导航栏上实现这一点
我想设计我的navigationBar如下图，我怎样才能实现这一点。它可以在navigationBar上使用，或者我不需要navigationBar。
话题＆amp;设置必须是按钮，因为我想导航到另一个viewController

使用自定义委托创建自定义导航栏..我使用此参见下面的示例..
创建CustomNavBar.h文件，如下文...
// Created by Paras on 03/12/11.
// Copyright 2010 __MyCompanyName__. All rights reserved.
//
#import <UIKit/UIKit.h>
#import "CustomNavBarDelegate.h"
@interface CustomNavBar : UIView {
NSObject<CustomNavBarDelegate> *delegate;
NSString *strCatOrLoc;
UIButton *btnBack;
UIButton *btnLeft;
UIImageView *imgRightImage;
UILabel *lbl;
UIImageView *imgTitle;
}
@property (nonatomic, retain) UIButton *btnBack;
@property (nonatomic, assign) NSObject<CustomNavBarDelegate> *delegate;
-(void)onclickBack:(id)sender;
- (id) initWithFrame: (CGRect)rect;
-(void)setImage:(UIImage*)img NavTitle:(NSString *)title;
-(void)setTitleImage:(UIImage*)img rightImage:(UIImage *)imgRight;
-(void)setwithoutlogo:(UIImage*)img NavTitle:(NSString *)title;
@end
现在看到CustomNavBar.m文件的代码如下...
// Created by Paras on 03/12/11.
// Copyright 2010 __MyCompanyName__. All rights reserved.
//
#import "CustomNavBar.h"
#import <QuartzCore/QuartzCore.h>
#import "AppDelegate.h"
@implementation CustomNavBar
@synthesize delegate;
@synthesize btnBack;
#pragma mark -
#pragma mark init methods
- (id) initWithFrame: (CGRect)rect {
if (self == [super initWithFrame:rect]) {
//[self setBackgroundColor:[UIColor colorWithRed:241.0f/255.0f green:241.0f/255.0f blue:237.0f/255.0f alpha:1.0f]];
// [self setBackgroundColor:[UIColor whiteColor]];
btnBack = [UIButton buttonWithType:UIButtonTypeCustom];
btnBack.frame = CGRectMake(10.0, 8.0, 50.0, 28.0);
[btnBack addTarget:self
action:@selector(onclickBack:)
forControlEvents:UIControlEventTouchDown];
btnBack.layer.masksToBounds = YES;
btnBack.layer.cornerRadius = 8.0;
btnBack.layer.borderWidth = 0.5;
btnBack.layer.borderColor = [[UIColor blackColor] CGColor];
//btnBack.titleLabel.textColor = [UIColor blackColor];
// btnBack.titleLabel.text = @"Back";
[btnBack.titleLabel setFont:Arial13];
[btnBack setTitle:@"" forState:UIControlStateNormal];
[btnBack setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
// [btnBack setBackgroundColor:[UIColor colorWithRed:241.0f/255.0f green:241.0f/255.0f blue:237.0f/255.0f alpha:1.0f]];
[btnBack setBackgroundColor:[UIColor clearColor]];
[self addSubview:btnBack];
btnLeft = [UIButton buttonWithType:UIButtonTypeCustom];
btnLeft.frame = CGRectMake(280.0, 8.0, 310.0, 28.0);
[btnLeft addTarget:self
action:@selector(onclickLeft:)
forControlEvents:UIControlEventTouchDown];
[btnLeft setBackgroundColor:[UIColor clearColor]];
[self addSubview:btnLeft];
}
return self;
}
-(void)setImage:(UIImage*)img NavTitle:(NSString *)title {
imgRightImage = [[UIImageView alloc] initWithFrame:CGRectMake(0.0,0.0,320.0,44.0)];
imgRightImage.contentMode = UIViewContentModeScaleAspectFill;
imgRightImage.clipsToBounds = YES;
imgRightImage.layer.masksToBounds = YES;
// imgRightImage.layer.cornerRadius = 11.0;
// imgRightImage.layer.borderWidth = 0.5;
[imgRightImage setImage:img];
[imgRightImage setBackgroundColor:[UIColor clearColor]];
[self addSubview:imgRightImage];
[imgRightImage release];
}
-(void)setwithoutlogo:(UIImage*)img NavTitle:(NSString *)title {
imgRightImage = [[UIImageView alloc] initWithFrame:CGRectMake(275.0,2.0,40.0,40.0)];
imgRightImage.contentMode = UIViewContentModeScaleAspectFill;
imgRightImage.clipsToBounds = YES;
imgRightImage.layer.masksToBounds = YES;
// imgRightImage.layer.cornerRadius = 11.0;
// imgRightImage.layer.borderWidth = 0.5;
//[imgRightImage setImage:img];
[imgRightImage setBackgroundColor:[UIColor clearColor]];
[self addSubview:imgRightImage];
[imgRightImage release];
lbl = [[UILabel alloc] initWithFrame:CGRectMake(70.0, 7.0, 180, 30.0)];
// lbl.font = [UIFont fontWithName:@"Arial" size:20.0];
lbl.font = Arial16;
lbl.numberOfLines = 1;
lbl.tag = 11;
lbl.backgroundColor = [UIColor clearColor];
lbl.textColor = [UIColor blackColor];
lbl.textAlignment = UITextAlignmentCenter;
lbl.text = title;
[self addSubview:lbl];
}
-(void)setTitleImage:(UIImage*)img rightImage:(UIImage *)imgRight {
imgRightImage = [[UIImageView alloc] initWithFrame:CGRectMake(275.0,2.0,40.0,40.0)];
imgRightImage.contentMode = UIViewContentModeScaleAspectFill;
imgRightImage.clipsToBounds = YES;
imgRightImage.layer.masksToBounds = YES;
[imgRightImage setImage:imgRight];
[imgRightImage setBackgroundColor:[UIColor clearColor]];
[self addSubview:imgRightImage];
[imgRightImage release];
imgTitle = [[UIImageView alloc] initWithFrame:CGRectMake(68.0,3.0,200.0,38.0)];
imgTitle.contentMode = UIViewContentModeScaleToFill;
[imgTitle setBackgroundColor:[UIColor clearColor]];
[imgTitle setImage:img];
[self addSubview:imgTitle];
[imgTitle release];
}
-(void)onclickLeft:(id)sender{
NSLog(@">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>Nav LeftClick");
[delegate btnleft_clicked:self];
}
-(void)onclickBack:(id)sender {
NSLog(@">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>Nav BackClick");
[delegate popViewController:self];
}
#pragma mark -
#pragma mark
- (void)dealloc {
//[array release];
[super dealloc];
}
@end
然后创建委托类文件，如bellow ..
@class CustomNavBar;
@protocol CustomNavBarDelegate
@required
- (void)popViewController:(CustomNavBar *)navBar;
-(void)btnleft_clicked:(CustomNavBar *)navBar1;
@end
在您的类中使用此代码之后..例如..
<。>在.h文件中导入它，然后像下面一样使用..#import "CustomNavBarDelegate.h"
@class CustomNavBar;
@interface ViewController : UIViewController<CustomNavBarDelegate>
{
CustomNavBar *navBar;
}
- (void)popViewController:(CustomNavBar *)navBar1;
@end
并在.m文件中定义该委托方法并创建和添加类似于下面的导航...
- (void)viewDidLoad
{
navBar = [[CustomNavBar alloc] initWithFrame:CGRectMake(0, 0, 322, 44)];
[navBar setDelegate:self];
[self.view addSubview:navBar];
[navBar setImage:[UIImage imageNamed:@"yourImageName"] NavTitle:@"yourTitle"];
}
- (void)popViewController:(CustomNavBar *)navBar1 {
// NSLog(@">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> delegate called");
[self.navigationController popViewControllerAnimated:YES];
}
-(void)btnleft_clicked:(CustomNavBar *)navBar1{
NSLog(@"\n\n btn Left Clicked InviteFriendsView");
}
注意：这只是一个示例，此处根据您的要求实施您的逻辑。
在这里你也可以在中间添加第3个按钮，并定义在Delegate和另一个.m文件中调用它的方法..
我希望这对你有帮助......

我这样做了，见下面的代码
//IvisionApps Button
UIButton *ivisionButton= [UIButton buttonWithType:UIButtonTypeCustom];
UIImage *ivisionButtonImage = [UIImage imageNamed:@"ivisionapps"];
UIImage *ivisionButtonImagePressed = [UIImage imageNamed:@"ivisionappsSelected"];
[ivisionButton setBackgroundImage:ivisionButtonImage forState:UIControlStateNormal];
[ivisionButton setBackgroundImage:ivisionButtonImagePressed forState:UIControlStateHighlighted];
[ivisionButton addTarget:self action:@selector(goIVisionApp) forControlEvents:UIControlEventTouchUpInside];
ivisionButton.frame = CGRectMake(-8, -20, 106, 38);
UIView *backButtonView = [[UIView alloc] initWithFrame:CGRectMake(-8, -20, 106, 38)];
backButtonView.bounds = CGRectOffset(backButtonView.bounds, -14, -7);
[backButtonView addSubview:ivisionButton];
UIBarButtonItem *backBarButton = [[UIBarButtonItem alloc] initWithCustomView:backButtonView];
self.navigationItem.rightBarButtonItem = backBarButton;
//Auxilaries Button
UIButton *auxiliariesButton= [UIButton buttonWithType:UIButtonTypeCustom];
UIImage *auxiliariesButtonImage = [UIImage imageNamed:@"Auxiliaries"];
UIImage *auxiliariesButtonImagePressed = [UIImage imageNamed:@"AuxiliariesSelected"];
[auxiliariesButton setBackgroundImage:auxiliariesButtonImage forState:UIControlStateNormal];
[auxiliariesButton setBackgroundImage:auxiliariesButtonImagePressed forState:UIControlStateHighlighted];
[auxiliariesButton addTarget:self action:@selector(goBack) forControlEvents:UIControlEventTouchUpInside];
auxiliariesButton.frame = CGRectMake(-19, -20, 106, 38);
UIView *auxiliariesButtonView = [[UIView alloc] initWithFrame:CGRectMake(-19, -20, 106, 38)];
auxiliariesButtonView.bounds = CGRectOffset(auxiliariesButtonView.bounds, -14, -7);
[auxiliariesButtonView addSubview:auxiliariesButton];
UIBarButtonItem *auxiliariesBarButton = [[UIBarButtonItem alloc] initWithCustomView:auxiliariesButtonView];
self.navigationItem.leftBarButtonItem = auxiliariesBarButton;
//hide backBarButton of NavigationItem
[self.navigationItem setHidesBackButton:YES];
