LTInfiniteScrollView
效果：
Usage - 使用
Create the scroll view by:
通过以下方式来创建出scroll view
self.scrollView = [[LTInfiniteScrollView alloc]initWithFrame:CGRectMake(0, 0, CGRectGetWidth(self.view.bounds), 200)];
[self.view addSubview:self.scrollView];
self.scrollView.dataSource = self;
[self.scrollView reloadData];
Then implement LTInfiniteScrollViewDataSource protocol:
然后实现LTInfiniteScrollViewDataSource协议方法：
@protocol LTInfiniteScrollViewDataSource <NSObject>
-(UIView*) viewAtIndex:(int)index reusingView:(UIView *)view;
-(int) totalViewCount;
-(int) visibleViewCount;
@end
Sample code:
示例源码：
-(int) totalViewCount
{
// you can set it to a very big number to mimic the infinite behavior, no performance issue here
return 100000000;
}
-(int) visibleViewCount
{
return 5;
}
-(UIView*) viewAtIndex:(int)index reusingView:(UIView *)view;
{
if(view){
((UILabel*)view).text = [NSString stringWithFormat:@"%d", index];
return view;
}
UILabel *aView = [[UILabel alloc]initWithFrame:CGRectMake(0, 0, 64, 64)];
aView.backgroundColor = [UIColor blackColor];
aView.layer.cornerRadius = 32;
aView.layer.masksToBounds = YES;
aView.backgroundColor = [UIColor colorWithRed:0/255.0 green:175/255.0 blue:240/255.0 alpha:1];
aView.textColor = [UIColor whiteColor];
aView.textAlignment = NSTextAlignmentCenter;
aView.text = [NSString stringWithFormat:@"%d", index];
return aView;
}
If you want to apply any animation during scrolling, implement LTInfiniteScrollViewDelegateprotocol:
如果你想在滑动期间实现其他的动画效果，实现这个LTInfiniteScrollViewDelegateprotocol协议即可：
@protocol LTInfiniteScrollViewDelegate <NSObject>
-(void) updateView:(UIView*) view withDistanceToCenter:(CGFloat)distance scrollDirection:(ScrollDirection)direction;
@end
See the example for details~
请从示例源码中查看更多的细节~
