MSScrollView

A block-based UIScrollView alternative which runs a handler block when scrolling, instead of using delegation. also notify the below information. know when using a didScroll block.

• ScrollView Direction

HORIZONTAL_SCROLL_MODE - LEFT_SCROLLING
- RIGHT_SCROLLING

VERTICAL_SCROLL_MODE - UP_SCROLLING
- DOWN_SCROLLING

• ScrollView Action

  During dragging(when user finger touch in screen) the scroll view always return UNKNOWN_ACTION. After dragging(user finger touch out screen, begin decelerating) there are two kinds of behavior are expected. Just moving go through direction, or bounce back to the original position.

Dragging
- UNKNOWN_ACTION

After Drag
- GO_THROUGH - GO_THROUGH_COMPLETE - BOUNCES_BACK - BOUNCES_BACK_COMPLETE

• Options

  - Embedded PageControl (currentPage, numberOfPages automatically update.)

More Information on MSScrollView refer to the header file.

Installation

MSScrollView is possible via CocoaPods. Just add the following to your Podfile.

platform :ios
pod 'MSScrollView'

Another way to, drag the included MSScrollView folder into your project.

Usage

These classes was written under the ARC. Be sure to specify -fobjc-arc the 'Compile Sources' Build Phase for each file if you aren't using ARC project-wide

Sample Code

#import "MSScrollView.h"

- (void)viewDidLoad
{
	self.myScrollView = [[MSScrollView alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
	_myScrollView.contentSize = CGSizeMake(320*10, IS_IPHONE_5?568:480);
	_myScrollView.pagingEnabled = YES;
	_myScrollView.backgroundColor = [UIColor whiteColor];
	_myScrollView.mode = HORIZONTAL_SCROLL_MODE;
	for(int i = 0; i<10; i++)
	{
		UIView *view = [[UIView alloc] initWithFrame:(CGRect){320*i,0,320,IS_IPHONE_5?568:480}];
		view.backgroundColor = [UIColor colorWithRed:(arc4random()%100)/100.0f green:(arc4random()%100)/100.0f blue:(arc4random()%100)/100.0f alpha:1.0f];
		UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 320, 60)];
		CGRect rect = label.frame;
		rect.origin.y = (view.frame.size.height - label.frame.size.height*2)/2;
		label.frame = rect;
		label.backgroundColor = [UIColor clearColor];
		label.text = [NSString stringWithFormat:@"Page %d", i+1];
		label.font = [UIFont systemFontOfSize:22.0f];
		label.textAlignment =NSTextAlignmentCenter;
		label.textColor = [UIColor whiteColor];
		[view addSubview:label];
		[_myScrollView addSubview:view];
	}
	
	[self.view addSubview:_myScrollView];
	[_myScrollView setPageControl:CGPointMake(160,IS_IPHONE_5?520:430)];
	
	_myScrollView.didscroll = ^(BOOL isDecelerating, ScrollViewDirection direction, ScrollViewAction action)
	{
		NSLog(@"didScroll | isDecelerating:%d, direction:%d, action:%d", isDecelerating, direction, action);
	};
	
	_myScrollView.beginDragging = ^{
		
		NSLog(@"beginDragging");
	};
	_myScrollView.endDragging = ^{
		
		NSLog(@"endDragging");
	};
	_myScrollView.beginDecelerating = ^{
		
		NSLog(@"beginDecelerating");
	};
	_myScrollView.endDecelerating = ^{
		
		NSLog(@"endDecelerating");
	};
	
	[super viewDidLoad];
}
