Uinavigationcontroller details 3 Toolbar

Original article: http://blog.csdn.net/totogo2010/article/details/7682131 special thank you.

1. Display Toolbar

Add the code in the-(void) viewdidload method of rootviewcontroller. m so that toobar is displayed.

 

[CPP]View plaincopy

1. [Self. navigationcontroller settoolbarhidden: No animated: Yes];

 

2. Add uibarbuttonitem on the toolbar

Create several uibarbuttonitems and add them to the toolbar as arrays.

 

[CPP]View plaincopy

1. Uibarbuttonitem * One = [[uibarbuttonitem alloc] initwithbarbuttonsystemitem: uibarbuttonsystemitemadd target: Nil action: Nil];
2. Uibarbuttonitem * Two = [[uibarbuttonitem alloc] initwithbarbuttonsystemitem: uibarbuttonsystemitembookmarks target: Nil action: Nil];
3. Uibarbuttonitem * Three = [[uibarbuttonitem alloc] initwithbarbuttonsystemitem: uibarbuttonsystemitemaction target: Nil action: Nil];
4. Uibarbuttonitem * Four = [[uibarbuttonitem alloc] initwithbarbuttonsystemitem: uibarbuttonsystemitemedit target: Nil action: Nil];
5. Uibarbuttonitem * flexitem = [[uibarbuttonitem alloc] initwithbarbuttonsystemitem: uibarbuttonsystemitemflexiblespace target: Nil action: Nil];
6. [Self settoolbaritems: [nsarray arraywithobjects: flexitem, one, flexitem, two, flexitem, three, flexitem, four, flexitem, nil];

Effect:

 

 

Note: using [self. navigationcontroller. toolbar setitems :( nsarray *) animated: <# (bool) #>] This method to add an item does not work. Now, when I add a toolbar dynamically, this will take effect.

 

3. dynamically add Toolbar

We add a dynamic toolbar in secondview.

Add in secondviewcontroller. h

 

[CPP]View plaincopy

1. # Import <uikit/uikit. h>
3. @ Interface secondviewcontroller: uiviewcontroller
4. {
5. Uitoolbar * toolbar;
6. }
7. @ End

Add in secondviewcontroller. m

 

 

[CPP]View plaincopy

1. -(Void) viewdidload
2. {
3. [Super viewdidload];
5. [Self. navigationcontroller settoolbarhidden: Yes animated: Yes];
7. Uibarbuttonitem * addbutton = [[uibarbuttonitem alloc] initwithbarbuttonsystemitem: uibarbuttonsystemitemsearch target: Self action: @ selector (gotothridview :)];
8. Toolbar = [[uitoolbar alloc] initwithframe: cgrectmake (0.0, self. view. frame. size. height-toolbar. frame. size. height-44.0, self. view. frame. size. width, 44.0)];
9. [Toolbar setbarstyle: uibarstyledefault];
10. Toolbar. autoresizingmask = uiviewautoresizingflexibletopmargin;
11. [Toolbar setitems: [nsarray arraywithobject: addbutton];
12. [Self. View addsubview: toolbar];
14. // Do any additional setup after loading the view from Its nib.
15. }

First, hide the toobar displayed during rootview.

 

[Self. navigationcontroller settoolbarhidden: yesanimated: Yes]; then, the new toolbar is added to the secondview and an item is set for toobar.

[Toolbarsetitems: [nsarrayarraywithobject: addbutton];

Barbuttonitem uses uibarbuttonsystemitemsearch. The effect is as follows:

4. Create a New thridview and jump from secondview

Commad + N create a thridviewcontroller,

This addbutton jumps to thridview

 

[CPP]View plaincopy

1. -(Void) gotothridview :( ID) sender
2. {
3. Thridviewcontroller * thridview = [[thridviewcontroller alloc] init];
4. [Self. navigationcontroller pushviewcontroller: thridview animated: Yes];
5. Thridview. Title = @ "thrid View ";
7. }

Jump second to third:

 

 

At this point, the uinavigationcontroller has been practicing almost.
