XTImageGridView is a very simple lib for build Grid View in iOS.

##Which scenes can you use this libary?

##Configuration
#####1.Add XTImageGirdView SDWebImage to your project.
#####2.Add Code #import "XTImageGirdView.h"
#####3.Initial Code:

self.gridView = [[XTImageGridView alloc] init];
_gridView.frame = CGRectMake(0, 0, XTScreenSize.width, self.view.bounds.size.height);
_gridView.edgeInsets = UIEdgeInsetsMake(45, (XTScreenSize.width-270)*0.5, 5, (XTScreenSize.width-270)*0.5);
_gridView.gridViewDelegate = self;
[self.view addSubview:_gridView];
[self.gridView reloadData];

#####4.Refresh Grid View:

_gridView.maxNumInRow = 10;
_gridView.numOfImageViews = 10;
[self.gridView reloadData];

#####5.Config Single View:
######XTImageGirdView has two styles.
One is XTImageGridViewStyleDefault,in this style,grid view default has an
add button at last.You can hide or show it.And the default single view has an image view,and has a delete button.
The default action you want delete view,you should long press on the view,then the delete button will be show and with
shaking animation.Also you can config it to show directly.

###After long press.

###Another style is XTImageGridViewStyleCustom,you can customize single view by yourself.

#####XTImageGridViewStyleDefault delegate method below can config view:

-(NSDictionary *)imageSourcesAtIndex:(int)index InGridView:(XTImageGridView *)gridView
{
	return @{@"name":[_attachArray objectAtIndex:index],@"isURL":@NO};
}

#####XTImageGridViewStyleCustom delegate method below can config view:

-(void)customViewAtIndex:(int)index CurrentView:(UIView *)curView InGridView:(XTImageGridView *)gridView
{
	//	curView.layer.borderColor = [UIColor redColor].CGColor;
	//	curView.layer.borderWidth = 2.0;
	
	CGFloat headViewWidth = 44.0;
	CGFloat headViewHeight = 44.0;
	CGFloat headViewX = (curView.bounds.size.width-headViewWidth)*0.5;
	CGFloat headViewY = (curView.bounds.size.height-headViewHeight)*0.5-10;
	UIImageView *headView = [[UIImageView alloc] initWithFrame:CGRectMake(headViewX, headViewY, 44, 44)];
	//	headView.backgroundColor = [UIColor redColor];
	headView.layer.cornerRadius = headViewWidth*0.5;
	headView.layer.borderWidth = 5.0;
	headView.layer.borderColor = [UIColor whiteColor].CGColor;
	headView.clipsToBounds = YES;
	[curView addSubview:headView];
	
	UIView *headViewLayer = [[UIView alloc] initWithFrame:CGRectMake(headViewX, headViewY, 44, 44)];
	headViewLayer.backgroundColor = [UIColor clearColor];
	headViewLayer.layer.borderColor = [UIColor colorWithRed:82/255.0 green:145/255.0 blue:24/255.0 alpha:1.0].CGColor;
	headViewLayer.layer.cornerRadius = headViewWidth*0.5;
	headViewLayer.layer.borderWidth = 1.0;
	headViewLayer.clipsToBounds = YES;
	[curView addSubview:headViewLayer];
	
	UILabel *nameLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, headViewY-20, curView.bounds.size.width, 20)];
	nameLabel.text = @"Lily";
	nameLabel.font = [UIFont systemFontOfSize:13.0];
	nameLabel.textColor = [UIColor colorWithRed:31/255.0 green:31/255.0 blue:31/255.0 alpha:1.0];
	nameLabel.textAlignment = NSTextAlignmentCenter;
	[curView addSubview:nameLabel];
	
	UILabel *statusLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, CGRectGetMaxY(headView.frame)+2, curView.bounds.size.width, 20)];
	statusLabel.text = @"Agree";
	statusLabel.font = [UIFont systemFontOfSize:13.0];
	statusLabel.textColor = [UIColor colorWithRed:31/255.0 green:31/255.0 blue:31/255.0 alpha:1.0];
	statusLabel.textAlignment = NSTextAlignmentCenter;
	[curView addSubview:statusLabel];
	
	UILabel *timeLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, CGRectGetMaxY(statusLabel.frame), curView.bounds.size.width, 20)];
	timeLabel.text = @"2016.07.08";
	timeLabel.font = [UIFont systemFontOfSize:13.0];
	timeLabel.textColor = [UIColor colorWithRed:111/255.0 green:111/255.0 blue:111/255.0 alpha:1.0];
	timeLabel.textAlignment = NSTextAlignmentCenter;
	[curView addSubview:timeLabel];
	
	if (index != gridView.numOfImageViews-1) {
		
		UIView *lineView1 = [[UIView alloc] initWithFrame:CGRectMake(curView.bounds.size.width-12.5, CGRectGetMidY(headView.frame)-1, 12.5, 2.0)];
		lineView1.backgroundColor = [UIColor colorWithRed:212/255.0 green:212/255.0 blue:212/255.0 alpha:1.0];
		[curView addSubview:lineView1];
	}
	
	if (index != 0) {
		
		UIView *lineView2 = [[UIView alloc] initWithFrame:CGRectMake(0, CGRectGetMidY(headView.frame)-1, 12.5, 2.0)];
		lineView2.backgroundColor = [UIColor colorWithRed:212/255.0 green:212/255.0 blue:212/255.0 alpha:1.0];
		[curView addSubview:lineView2];
	}
	
	
}
