You have seen the dashboard in iPhone UI or in Mac OS X UI. The following code snippet shows you how to create a dashboard in iPhone native application.
The code is Object C format
- (UIButtonBar *)createButtonBar
{
UIButtonBar *myButtonBar;
myButtonBar = [[UIButtonBar alloc]
initInView: self
withFrame: CGRectMake(10.0f, 380.0f, 300.0f, 100.0f)
withItemList: [self buttonBarItemList]];
[myButtonBar setDelegate: self];
// This set the style of the bar
[myButtonBar setBarStyle: 3];
// This set the tracking mode (effect when clicking on the button of the bar)
[myButtonBar setButtonBarTrackingMode: 1];
int buttons[3] = { 1, 2, 3 };
[myButtonBar registerButtonGroup: 0 withButtons: buttons withCount: 3];
[myButtonBar showButtonGroup: 0 withDuration: 0.0];
/* This set the layout of the button */
int tag;
for (tag = 1; tag < 4; tag++)
{
[[myButtonBar viewWithTag: tag]
setFrame: CGRectMake(10.0f + ((tag-1)*(80.0 + 10.0)), 1.0f, 100.0f, 80.0f)
];
}
return myButtonBar;
}
The item list of the button bar
- (NSArray *)buttonBarItemList
{
return [NSArray arrayWithObjects:
[NSDictionary dictionaryWithObjectsAndKeys:
@"buttonBarClicked:", kUIButtonBarButtonAction,
@"button_back.png", kUIButtonBarButtonInfo,
@"button_back_pressed.png", kUIButtonBarButtonSelectedInfo,
[NSNumber numberWithInt: 1], kUIButtonBarButtonTag,
self, kUIButtonBarButtonTarget,
@"Page 1", kUIButtonBarButtonType,
@"0", kUIButtonBarButtonType,
nil
],
[NSDictionary dictionaryWithObjectsAndKeys:
@"buttonBarClicked:", kUIButtonBarButtonAction,
@"button_open.png", kUIButtonBarButtonInfo,
@"button_open_pressed.png", kUIButtonBarButtonSelectedInfo,
[NSNumber numberWithInt: 2], kUIButtonBarButtonTag,
self, kUIButtonBarButtonTarget,
@"Page 2", kUIButtonBarButtonType,
@"0", kUIButtonBarButtonType,
nil
],
[NSDictionary dictionaryWithObjectsAndKeys:
@"buttonBarClicked:", kUIButtonBarButtonAction,
@"button_next.png", kUIButtonBarButtonInfo,
@"button_next_pressed.png", kUIButtonBarButtonSelectedInfo,
[NSNumber numberWithInt: 3], kUIButtonBarButtonTag,
self, kUIButtonBarButtonTarget,
@"Page 3", kUIButtonBarButtonType,
@"0", kUIButtonBarButtonType,
nil
],
nil];
}
The click message, which will handle the click event of the button bar
- (void)buttonBarClicked: (id) sender
{
}
And you will got a nice UI like this
That's all, Have fun with iPhone & Object C coding
