The fisheye from our Bubble Browser for iPad.
Checkout demo project for some real life action!
Setup a dataSource, an optional delegate, add subview and you're done
MCSFishEyeView *fisheye = [[MCSFishEyeView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 50.0f, 600.0f)];
fisheye.dataSource = self;
fisheye.delegate = self;
[self.view addSubview:fisheye];
MCSFishEyeView has the notion of items, which are more or less similar to table view cells. Each item should be a subclass of MCSFishEyeViewItem, as it already provides convinent methods for setting highlighted and selected state. You register a class to MCSFishEyeView by this one-liner:
[fisheye registerItemClass:[MCSExampleFishEyeItem class]];
Inside your custom MCSFishEyeViewItem subclass you are free to do whatever you want in both
- (void)setSelected:(BOOL)selected animated:(BOOL)animated
and
- (void)setHighlighted:(BOOL)highlighted animated:(BOOL)animated
methods, just make sure you call super (don't worry, compiler will warn you if you forget to do so).
MCSFishEyeView has three different states:
-
MCSFishEyeStateCollapsed- in this state all the items are collapsed, no item ishighlightedorselected -
MCSFishEyeStateExpandedActive- items are moving around according to touch location, at most one element ishighlighted, no elements areselected -
MCSFishEyeStateExpandedPassive- in this state a single item is standing out inselectedstate, all the other items are collapsed
