我将 a 添加UIButton到UIToolbar我不想作为 a 的 a 中，以便我可以更好地控制框架内部UIBarButtonItem的位置。UIButton我为“正常”和“选定”状态设置了不同的标题。对于 a 来说，一切都完全正常，除了当它处于“选定”状态时， 的标题UIButton前面有一个 1 像素的点。UIButton

工具栏：

    UIToolbar *customView = [[UIToolbar alloc] initWithFrame:CGRectMake(HEADER_MARGIN, 0, HEADER_WIDTH, HEADER_HEIGHT)];
[customView setBarTintColor:[UIColor whiteColor]];

按钮：

UIButton *listOrderButton = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, ORDER_BUTTON_WIDTH, ORDER_BUTTON_HEIGHT)];
[listOrderButton setCenter:CGPointMake(customView.center.x, HEADER_HEIGHT/2)];
[listOrderButton.titleLabel setFont:[UIFont systemFontOfSize:ORDER_BUTTON_FONT_SIZE]];
[listOrderButton.titleLabel setTextAlignment:NSTextAlignmentCenter];
[listOrderButton setTitle:@"ABC" forState:UIControlStateNormal];
[listOrderButton setTitle:@"Time" forState:UIControlStateSelected];
[listOrderButton setTitleColor:[UIColor blueAppColor] forState:UIControlStateNormal];
[listOrderButton addTarget:self action:@selector(listOrderChange:) forControlEvents:UIControlEventTouchUpInside];
[customToolbar addSubview:listOrderButton];

和选择器：

- (void)listOrderChange:(UIButton *)sender {
[sender setSelected:!sender.selected];
}
