• 初始化
  

  IBOutlet UIToolbar    *toolbar; //create toolbar using new toolbar = [UIToolbar new]; toolbar.barStyle = UIBarStyleDefault; [toolbar sizeToFit]; toolbar.frame = CGRectMake(0, 410, 320, 50); //Add buttons UIBarButtonItem *systemItem1 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd                                                                              target:self                                                                              action:@selector(pressButton1:)]; UIBarButtonItem *systemItem2 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAction                                                                              target:self                                                                              action:@selector(pressButton2:)]; UIBarButtonItem *systemItem3 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCamera                                                                              target:self                                                                              action:@selector(pressButton3:)]; //Use this to put space in between your toolbox buttons UIBarButtonItem *flexItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace                                                                           target:nil                                                                           action:nil]; //Add buttons to the array NSArray *items = [NSArray arrayWithObjects: systemItem1, flexItem, systemItem2, flexItem, systemItem3, nil]; //release buttons [systemItem1 release]; [systemItem2 release]; [systemItem3 release]; [flexItem release]; //add array of buttons to toolbar [toolbar setItems:items animated:NO]; [self.view addSubview:toolbar];

• style
  

  typedef enum {     UIBarButtonSystemItemDone,     UIBarButtonSystemItemCancel,     UIBarButtonSystemItemEdit,      UIBarButtonSystemItemSave,      UIBarButtonSystemItemAdd,     UIBarButtonSystemItemFlexibleSpace,     UIBarButtonSystemItemFixedSpace,     UIBarButtonSystemItemCompose,     UIBarButtonSystemItemReply,     UIBarButtonSystemItemAction,     UIBarButtonSystemItemOrganize,     UIBarButtonSystemItemBookmarks,     UIBarButtonSystemItemSearch,     UIBarButtonSystemItemRefresh,     UIBarButtonSystemItemStop,     UIBarButtonSystemItemCamera,     UIBarButtonSystemItemTrash,     UIBarButtonSystemItemPlay,     UIBarButtonSystemItemPause,     UIBarButtonSystemItemRewind,     UIBarButtonSystemItemFastForward, #if __IPHONE_3_0 <= __IPHONE_OS_VERSION_MAX_ALLOWED     UIBarButtonSystemItemUndo,     UIBarButtonSystemItemRedo, #endif #if __IPHONE_4_0 <= __IPHONE_OS_VERSION_MAX_ALLOWED     UIBarButtonSystemItemPageCurl, #endif } UIBarButtonSystemItem;

• Type 初始化, 提供 Custom/RoundedRect/Detail/Info/ContactAdd, 使用 Custom 時記得要給 Frame
  

  UIButton* button3 = [UIButton buttonWithType:UIButtonTypeCustom]; [button3 addTarget:self action:@selector(backAction) forControlEvents:UIControlEventTouchUpInside]; [button3 setTitle:@"+" forState:UIControlStateNormal]; [button3 setTitleColor:[UIColor redColor] forState:UIControlStateNormal]; button3.titleLabel.font = [UIFont systemFontOfSize:25]; button3.frame = CGRectMake(100, 170, 100, 30); // create button item -- possible because UIButton subclasses UIView! UIBarButtonItem *systemItem3=[[UIBarButtonItem alloc] initWithCustomView:button3];

• type
  

  typedef enum {     UIButtonTypeCustom = 0,     UIButtonTypeRoundedRect,     UIButtonTypeDetailDisclosure,     UIButtonTypeInfoLight,     UIButtonTypeInfoDark,     UIButtonTypeContactAdd, } UIButtonType;
