我有一个左键按钮项。但是我希望它能够向右移动它。此刻它粘在左手边。任何机构都知道如何实现这个目标?
这是按钮本身的代码。
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];
希望有人能帮助我。
亲切的问候

为什么不直接添加右键按钮?
self.tabBarController.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(changeStatus:)] autorelease];

这就是我为我所做的工作
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];
