我正在使用导航栏按钮items.i使用以下代码来执行此操作

UIBarButtonItem *btnSave = [[UIBarButtonItem alloc] 
                                    initWithTitle:@"Save"                                            
                                    style:UIBarButtonItemStyleBordered 
                                    target:self 
                                 action:@selector(save_Clicked:)];
     self.navigationItem.rightBarButtonItem = btnSave;
     [btnSave release];

     UIBarButtonItem *btnCancel = [[UIBarButtonItem alloc] 
                                    initWithTitle:@"Cancel"                                            
                                    style:UIBarButtonItemStyleBordered 
                                    target:self 
                                    action:@selector(save_Clicked)];
     self.navigationItem.leftBarButtonItem = btnCancel;
     [btnCancel release];

我的问题是如何在左侧栏按钮项旁边添加另一个按钮.

解决方法

要执行此操作,您需要创建一个工具栏,然后继续向其添加UIButton,然后将工具栏设置为leftBarButton

像这样的东西：

UIToolbar* tools = [[UIToolbar alloc] initWithFrame:CGRectMake(0,250,44)];
tools.tintColor = [UIColor clearColor];
[tools setTranslucent:YES];

NSMutableArray* buttons = [[NSMutableArray alloc] initWithCapacity:9];

UIImage *myImage = [UIImage imageNamed:@"AL_HomeMod_Icon.png"];
UIButton *myButton = [UIButton buttonWithType:UIButtonTypeCustom];
[myButton setImage:myImage forState:UIControlStateNormal];
myButton.showsTouchWhenHighlighted = YES;
myButton.frame = CGRectMake(0.0,0.0,myImage.size.width,myImage.size.height);

[myButton addTarget:self action:@selector(clickViewHomeMod) forControlEvents:UIControlEventTouchUpInside];

UIBarButtonItem *bi = [[UIBarButtonItem alloc]
                       initWithCustomView:myButton];

[buttons addObject:bi];
[bi release];

myImage = [UIImage imageNamed:@"AL_History_Icon.png"];
myButton = [UIButton buttonWithType:UIButtonTypeCustom];
[myButton setImage:myImage forState:UIControlStateNormal];
myButton.showsTouchWhenHighlighted = YES;
myButton.frame = CGRectMake(0.0,myImage.size.height);

[myButton addTarget:self action:@selector(clickViewHistory) forControlEvents:UIControlEventTouchUpInside];

bi = [[UIBarButtonItem alloc]
      initWithCustomView:myButton];

[buttons addObject:bi];
[bi release];

myImage = [UIImage imageNamed:@"AL_RX_Icon.png"];
myButton = [UIButton buttonWithType:UIButtonTypeCustom];
[myButton setImage:myImage forState:UIControlStateNormal];
myButton.showsTouchWhenHighlighted = YES;
myButton.frame = CGRectMake(0.0,myImage.size.height);

[myButton addTarget:self action:@selector(clickViewCustomPopView2) forControlEvents:UIControlEventTouchUpInside];

bi = [[UIBarButtonItem alloc]
      initWithCustomView:myButton];

[buttons addObject:bi];
[bi release];

myImage = [UIImage imageNamed:@"AL_User_Icon.png"];
myButton = [UIButton buttonWithType:UIButtonTypeCustom];
[myButton setImage:myImage forState:UIControlStateNormal];
myButton.showsTouchWhenHighlighted = YES;
myButton.frame = CGRectMake(0.0,myImage.size.height);

[myButton addTarget:self action:@selector(clickViewCustomPopView:) forControlEvents:UIControlEventTouchUpInside];
bi = [[UIBarButtonItem alloc]
      initWithCustomView:myButton];
[buttons addObject:bi];
popButton = myButton;
[bi release];


// stick the buttons in the toolbar
[tools setItems:buttons animated:NO];

[buttons release];

// and put the toolbar in the nav bar
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:tools];
[tools release];

希望有所帮助
