Stock Ticker

Stock Ticker is simply a file that will allow to pass views and number of views to get display on your tickerView.

Ticker you have always see on pull down shutter in your iphone.
Here I have passed stock Views and Currency views.
You can pass your views to display.This is a continuous object display.No space will come then ticker ends.It will continue with first object of the ticker Views array.

 

Using:- To use it,import StockTicker.h file in your code window.Made an array of UIViews or UILabels whatever you want to display as objects on your ticker.

 

  Make TickerView instance as

StockTiker *stkticker=[[StockTiker alloc] initWithFrame:CGRectMake(0, 0, 320, 20)];

  Set its properties as

	stkticker.tdelegate=self;
	stkticker.ttag=0;
	[stkticker setBackgroundColor:[UIColor clearColor]];
	[self.navigationController.navigationBar addSubview:stkticker];

  Implement its delegate method as:

	#pragma mark- UITickerView delegate method
	- (NSInteger)numberOfRowsintickerView:(StockTiker *)tickerView
	{
	return [objectArray count];
	}
	- (id)tickerView:(StockTiker*)tickerView cellForRowAtIndex:(int)index
	{
	return [objectArray objectAtIndex:index];
	}
	@end
