2, add Uibarbuttonitem on the toolbar

Create a few uibarbuttonitem and add it as an array to the toolbar

[OBJC]View Plaincopyprint? < param name= "wmode" value= "Transparent" >

2. Uibarbuttonitem *camera=[[uibarbuttonitem alloc] Initwithbarbuttonsystemitem:uibarbuttonsystemitemcamera  target:self Action:@selector (Clicktoolbarbutton)];
4. [Camera setwidth:80];
6. uibarbuttonitem *refresh=[[uibarbuttonitem alloc] initwithbarbuttonsystemitem:  Uibarbuttonsystemitemrefresh target:self Action:@selector (Clicktoolbarbutton)];
8. [Refresh setwidth:80];
10. uibarbuttonitem *reply=[[uibarbuttonitem alloc] initwithbarbuttonsystemitem:  Uibarbuttonsystemitemreply target:self Action:@selector (Clicktoolbarbutton)];
12. [Reply setwidth:80];
14. uibarbuttonitem *compose=[[uibarbuttonitem alloc] initwithbarbuttonsystemitem:  Uibarbuttonsystemitemcompose target:self Action:@selector (Clicktoolbarbutton)];
16. [Compose setwidth:80];
20. uibarbuttonitem *splitspace=[[uibarbuttonitem alloc] initwithbarbuttonsystemitem:  Uibarbuttonsystemitemflexiblespace target: nil action: nil];
24. [self settoolbaritems:[nsarray arraywithobjects:splitspace,camera,splitspace,refresh,splitspace,  Reply,splitspace,compose,splitspace, nil Nil]];

Define the Click event with the following code:

[OBJC]View Plaincopyprint?

1. -(void) clicktoolbarbutton{
2. NSLog (@ "you clicked!");
3. }

The final run is as follows:

Description: Using [Self.navigationcontroller Settoolbaritems:[nsarray Arraywithobjects:splitspace,camera,splitspace,refresh, Splitspace,reply,splitspace,compose,splitspace, nil] animated:yes]; adding is not working.

3, custom toolbar, first create a new page, in the header file declaration Uitoolbar *toolbar;
To implement the custom toolbar in the Viewdidload method in the implementation file, the implementation code is as follows:

[OBJC]View Plaincopyprint?

2. -(void) Viewdidload
6. [Super Viewdidload];
8. [self. Navigationcontroller Settoolbarhidden:Yes animated:Yes];
10. //Custom UIView
12. UIButton *btn=[uibutton Buttonwithtype:uibuttontypecontactadd];
16. [Btn addTarget:self action: nil forcontrolevents:uicontroleventtouchupinside];
18. uibarbuttonitem *firstbutton=[[uibarbuttonitem alloc] initwithcustomview:btn];
20. [Firstbutton setwidth:120];
22. //System comes with a view
24. uibarbuttonitem *addbutton=[[uibarbuttonitem alloc] initwithbarbuttonsystemitem:  Uibarbuttonsystemitembookmarks target:self Action: nil];
26.    toolbar=[[uitoolbar alloc]  Initwithframe:cgrectmake (0, self .view.frame.size.height-toolbar.frame.size< Span class= "xcodeconstants" >.height-44,  self.view.frame.size.width, 4 4)];   
28. [Toolbar Setbarstyle:uibarstyledefault];
30. Toolbar. Autoresizingmask=uiviewautoresizingflexibletopmargin;
32. [Toolbar Setitems:[nsarray Arraywithobjects:addbutton,firstbutton,Nil]];
34. [self. View Addsubview:toolbar];
