如何在导航栏中添加两个按钮并留出一些空间

Question

我在导航栏中添加了两个按钮，它们工作正常，但我希望它们之间有空间，它们都结合在一起，我希望它们之间有一点空间

  UIBarButtonItem *btnAdd = [[UIBarButtonItem alloc] initWithTitle:@"Add"
                                                           style:UIBarButtonItemStylePlain
                                                          target:self
                                                          action:@selector(Add)];

UIBarButtonItem *btnEdit = [[UIBarButtonItem alloc] initWithTitle:@"Add"
                                                           style:UIBarButtonItemStylePlain
                                                          target:self
                                                          action:@selector(Add)];


UIToolbar *rightToolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 100, 44)];
rightToolBar.backgroundColor = [UIColor clearColor];
rightToolBar.tintColor = [UIColor colorWithRed:40.0/255.0 green:48.0/255.0 blue:51.0/255.0 alpha:0.0];
NSArray *buttonsRight = [NSArray arrayWithObjects:btnEdit, btnAdd, nil];
[rightToolBar setItems:buttonsRight];

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

Answer 1

您可以在UIBarButtonItem 之间添加这两个中的任何一个

UIBarButtonItem *fixed = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil]

UIBarButtonItem *flexible = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil]

注意要设置固定空间UIBarButtonItem的宽度，需要设置.width属性

[fixed setWidth:455.0f];
