將左欄按鈕項目向右移更多

Question

我有一個左鍵按鈕項。 但是我希望它向右移動。 此刻，它粘在左側。 任何人都知道我該如何實現？

這是按鈕本身的代碼。

 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];

希望有人可以幫我這個忙。

親切的問候

Answer 1

為什么不直接添加右鍵按鈕？

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

Answer 2

這就是我所做的對我有用的

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];
