IOS中UITableview中封装九宫格

第一步引入SecondNav目录即可

第二步引入头文件 

#import "DIYTableView.h"

#import "invoiceInfo.h"

实现协议

DIYButtonDelegate

- (void)viewDidLoad
{
    [super viewDidLoad];

   NSMutableArray *mydata=[NSMutableArrayarray];

    NSString *path=[[NSBundlemainBundle] pathForResource:@"Pad_menu_level"ofType:@"json"];

    NSError * error=nil;

    NSString *content=[NSStringstringWithContentsOfFile:path encoding:NSUTF8StringEncodingerror:&error];

    if (error) {

        NSLog(@"读取%@错误",path);

        return;

    }

    

    NSArray *ContentArrary=[content JSONValue];

    for (NSDictionary *dic in ContentArrary) {

        InvoiceInfo *info=[InvoiceInfoInvoice:dic];

        [mydata addObject:info];

    }

    CGFloat h=tpRec.size.height-KBottom;

    CGRectDivide(tpRec, &imgRec, &tpRec, h, CGRectMinYEdge);

    

 

    CGRect navRect=UIEdgeInsetsInsetRect(imgRec, UIEdgeInsetsMake(5, 5, 5, 5));

    //二级导航

    DIYTableView *NavSecond=[[DIYTableViewalloc] initWithFrame:navRect delegate:self];

    [self.view addSubview: NavSecond];

    NavSecond.aData=mydata;

    [NavSecond release];

    

}

//实现代理方法
-(void)DiyButtonClick:(DIYButton *) btn{
    NSLog(@"title-->%@",btn.titleLabel.text);
}

viewcontroller用法 必须实现

DIYButtonDelegate协议
