iphone - 将左侧的 barbutton 项目更多地向右移动

Question

我有一个左栏按钮项目。但我希望它更向右移动。目前它粘在左侧。任何人都知道我该如何实现这一目标？

这是我的按钮本身的代码。

 UIButton *button =  [UIButton buttonWithType:UIButtonTypeCustom];
    [button setBackgroundImage:[UIImage imageNamed:@"task_status.png"] forState:UIControlStateNormal];
    [button addTarget:self action:@selector(changeStatus:) forControlEvents:UIControlEventTouchUpInside];
    [button setFrame:CGRectMake(80, 0,100, 18)];
    self.tabBarController.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:button];

希望有人能帮我解决这个问题。

亲切的问候

Answer 1

为什么不直接添加右栏按钮？

self.tabBarController.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(changeStatus:)] autorelease];

Answer 2

这就是我所做的它对我有用

UIImage *image = [UIImage imageNamed:@"btn_bar_back.png"] ;
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(10.0, -15.0, image.size.width, image.size.height);//set your button frame
[button setBackgroundImage:image forState:UIControlStateNormal];
[button setTitle:@"BACK" forState:UIControlStateNormal];
button.contentEdgeInsets = UIEdgeInsetsMake(0, 8, 0, 0);// if want to move text more towards right
[button addTarget:self action:@selector(backButtonPressed:) forControlEvents:UIControlEventTouchUpInside];
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, image.size.width+10, 50)];
button.center = CGPointMake(view.center.x, view.center.y);
[view addSubview:button];

self.navigationItem.leftBarButtonItem = [[[UIBarButtonItem alloc] initWithCustomView:view] autorelease];

[view release];
