[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" 
 
 
@interface KKFirstViewController : UIViewController<ASIHTTPRequestDelegate, AQGridViewDelegate, AQGridViewDataSource> 
 
@property(nonatomic, retain)AQGridView *gridView; 
 
@end 
#import <UIKit/UIKit.h>
#import "ASIHTTPRequest.h"
#import "AQGridView.h"


@interface 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" 
 
@interface GridViewCell : AQGridViewCell 
 
@property(nonatomic, retain)UIImageView *imageView; 
@property(nonatomic, retain)UILabel *captionLabel; 
 
@end 
#import "AQGridViewCell.h"

@interface 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];
