[iPhone中级] iPhone团购信息客户端的开发 (三)

接上二篇的内容，今天我们就来介绍一下如何将解析出来的数据放入AQGridView中显示出来，因为我们的工程中已经将AQGridView导入了，所以我们在KKFirstViewController中直接可以引用

[plain]
#import <UIKit/UIKit.h>
#import "ASIHTTPRequest.h"
#import "AQGridView.h"

@inte易做图ce KKFirstViewController : UIViewController<ASIHTTPRequestDelegate, AQGridViewDelegate, AQGridViewDataSource>

@property(nonatomic, retain)AQGridView *gridView;

@end
#import <UIKit/UIKit.h>
#import "ASIHTTPRequest.h"
#import "AQGridView.h"

@inte易做图ce KKFirstViewController : UIViewController<ASIHTTPRequestDelegate, AQGridViewDelegate, AQGridViewDataSource>

@property(nonatomic, retain)AQGridView *gridView;

@end这里加入了AQGridViewDelegate和AQGridViewDataSource这两个委托，简单一点我们可以把AQGridView看成UITableView，同样的道理，一个是数据源的方法，一个就是选中的方法

然后就是
在-(void)viewDidLoad这个方法中，我们加入了

[plain]
self.gridView = [[AQGridView alloc] initWithFrame:CGRectMake(0, 0, 320, 460)];
self.gridView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
self.gridView.autoresizesSubviews = YES;
self.gridView.delegate = self;
self.gridView.dataSource = self;

[self.view addSubview:gridView];
    self.gridView = [[AQGridView alloc] initWithFrame:CGRectMake(0, 0, 320, 460)];
    self.gridView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
    self.gridView.autoresizesSubviews = YES;
    self.gridView.delegate = self;
    self.gridView.dataSource = self;

    [self.view addSubview:gridView];将当前的gridView加入主视图中

接着还有两个方法一定需要实现的

[plain]
#pragma mark AQGridViewDataSource
//总共有的Item
-(NSUInteger)numberOfItemsInGridView:(AQGridView *)gridView{

    return [arrays count];
}
//每个Item
-(AQGridViewCell *)gridView:(AQGridView *)aGridView cellForItemAtIndex:(NSUInteger)index{

    static NSString *identifier = @"PlainCell";

    GridViewCell *cell = (GridViewCell *)[aGridView dequeueReusableCellWithIdentifier:identifier];

    if(cell == nil){

        cell = [[GridViewCell alloc] initWithFrame:CGRectMake(0, 0, 160, 123) reuseIdentifier:identifier];
    }

    //取得每一个字典
    NSDictionary *dict = [arrays objectAtIndex:index];

    [cell.captionLabel setText:[dict objectForKey:kName_Title]];

    return cell;

}

//每个显示框大小
-(CGSize)portraitGridCellSizeForGridView:(AQGridView *)gridView{

    return CGSizeMake(160, 123);
}
#pragma mark AQGridViewDataSource
//总共有的Item
-(NSUInteger)numberOfItemsInGridView:(AQGridView *)gridView{

    return [arrays count];
}
//每个Item
-(AQGridViewCell *)gridView:(AQGridView *)aGridView cellForItemAtIndex:(NSUInteger)index{

    static NSString *identifier = @"PlainCell";

    GridViewCell *cell = (GridViewCell *)[aGridView dequeueReusableCellWithIdentifier:identifier];

    if(cell == nil){

        cell = [[GridViewCell alloc] initWithFrame:CGRectMake(0, 0, 160, 123) reuseIdentifier:identifier];
    }

    //取得每一个字典
    NSDictionary *dict = [arrays objectAtIndex:index];

    [cell.captionLabel setText:[dict objectForKey:kName_Title]];

    return cell;

}

//每个显示框大小
-(CGSize)portraitGridCellSizeForGridView:(AQGridView *)gridView{

return CGSizeMake(160, 123);
}
这里还少一个类，就是GridView，这个类继承了AQGridViewCell，里面就是我们单独要显示的一个Item

[plain] view plaincopyprint?#import "AQGridViewCell.h"

@inte易做图ce GridViewCell : AQGridViewCell

@property(nonatomic, retain)UIImageView *imageView;
@property(nonatomic, retain)UILabel *captionLabel;

@end
#import "AQGridViewCell.h"

@inte易做图ce GridViewCell : AQGridViewCell

@property(nonatomic, retain)UIImageView *imageView;
@property(nonatomic, retain)UILabel *captionLabel;

@end图片显示的是团购信息中的图片，还有一个是文本

[plain]
#import "GridViewCell.h"

@implementation GridViewCell

@synthesize imageView,captionLabel;

- (id)initWithFrame:(CGRect)frame reuseIdentifier:(NSString *)reuseIdentifier
{
    self = [super initWithFrame:frame reuseIdentifier:reuseIdentifier];
    if (self) {

        UIView *mainView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 160, 123)];
        [mainView setBackgroundColor:[UIColor clearColor]];

        UIImageView *frameImageView = [[UIImageView alloc] initWithFrame:CGRectMake(9, 4, 142, 117)];
        [frameImageView setImage:[UIImage imageNamed:@"tab-mask.png"]];

        self.imageView = [[UIImageView alloc] initWithFrame:CGRectMake(13, 8, 135, 84)];

        self.captionLabel = [[UILabel alloc] initWithFrame:CGRectMake(13, 92, 127, 21)];
        [captionLabel setFont:[UIFont systemFontOfSize:14]];

        [mainView addSubview:imageView];
        [mainView addSubview:frameImageView];
        [mainView addSubview:captionLabel];

        [self.contentView addSubview:mainView];
