将uibarButtonSystemAdd和uibarButtonSystemTrash添加到导航项或uiSegmentedControl的一侧

我也做过类似的事情。我通过创建一个包含两个ui按钮的uiview子类,将两个ui按钮添加到导航项/栏中。然后您可以这样做:

MyUIViewSubclass *tempview = [[[MyUIViewSubclass alloc] initWithFrame:CGRectMake(234,4,84,30)] autorelease];
UIBarButtonItem newButton = [[[UIBarButtonItem alloc] initWithCustomView:tempview] autorelease];
[self.navigationItem setRightBarButtonItem:newButton animated:NO];

你所要做的就是把按钮放在 MyUIViewSubclass 你很好。

另外,我在自定义的init命令中传递目标的ID,以便更容易地确定视图中按钮的目标。所以 myuiviewSubclass(myuiviewSubclass) 而不是 initWithFrame ,我有这样的东西:

- (id)initWithFrame:(CGRect)aRect andTarget:(id)newTarget {
    if (self = [super initWithFrame:aRect]) {



        UIButton *editbtn = [[[UIButton alloc]  initWithFrame:fframe] autorelease];
        [editbtn addTarget:newTarget action:@selector(MBEdit) forControlEvents:UIControlEventTouchUpInside];

        [self addSubview:editbtn];
        [self setFirstbutton:editbtn];
        [editbtn release];



        UIButton *newbtn = [[[UIButton alloc]  initWithFrame:fframe] autorelease];
        [newbtn addTarget:newTarget action:@selector(MBNew) forControlEvents:UIControlEventTouchUpInside];

        [self addSubview:newbtn];
        [self setSecondbutton:newbtn];
        [newbtn release];

    }

    return self;

}

通过将多个按钮包装在 UIToolbar , sample code .
