推荐答案
要做到这一点,你需要创建一个工具栏,然后继续添加UIButton,然后设置工具栏为leftBarButton
To do this you need to create a toolbar then keep adding UIButton to it, then set the toolbar as the leftBarButton
如下所示:
UIToolbar* tools = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 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, 0.0, myImage.size.width, 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, 0.0, myImage.size.width, 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, 0.0, myImage.size.width, 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];
