如何摆脱UIToolBar中按钮顶部的线条

Question

我创建了UIToolBar并设置了两个UIBarButtonItem，然后将此工具栏分配给self.navigationItem.rightBarButtonItem。

除了按钮顶部有一条线外，一切都很完美。

代码：

UIBarButtonItem *addItem = [[UIBarButtonItem alloc] initWithTitle:@"Add" 
                                                            style:UIBarButtonItemStylePlain 
                                                           target:self
                                                           action:@selector(addNewRow:)];
UIBarButtonItem *editItem = [[UIBarButtonItem alloc] initWithTitle:@"Edit" 
                                                            style:UIBarButtonItemStylePlain 
                                                           target:self 
                                                           action:@selector(editRow:)];

UIToolbar *toolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 100, 30)];
[toolBar setItems:@[addItem, editItem]];

self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:toolBar];

你通过摆脱工具栏摆脱了这条线。

UIBarButtonItem *addItem = [[UIBarButtonItem alloc] initWithTitle:@"Add" style:UIBarButtonItemStylePlain target:self action:@selector(addNewRow:)];
UIBarButtonItem *editItem = [[UIBarButtonItem alloc] initWithTitle:@"Edit" style:UIBarButtonItemStylePlain target:self action:@selector(editRow:)];

self.navigationItem.rightBarButtonItems = @[ addItem, editItem ];
