XTImageGridView是一个用于在iOS中构建网格视图的非常简单的库。

##哪些场景可以使用这个库？

##配置
#####1.将XTImageGirdView SDWebImage添加到您的项目中。
#####2.添加代码#import "XTImageGirdView.h"
#####3.初始代码

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.刷新网格视图

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

#####5.配置单个视图
######XTImageGirdView有两种风格。
一种是XTImageGridViewStyleDefault，在这个风格中，网格视图默认有一个
添加按钮在最后。您可以隐藏或显示它。默认的单个视图有一个图像视图，还有一个删除按钮。
如果您想删除视图，您应该在视图中长按，然后删除按钮将显示并伴有
摇晃动画。您还可以配置它直接显示。

###长按后。

###另一种风格是XTImageGridViewStyleCustom，您可以通过自己自定义单个视图。

#####以下为XTImageGridViewStyleDefault的代理方法可以配置视图

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

#####以下为XTImageGridViewStyleCustom的代理方法可以配置视图

-(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];
	}
	
	
}
