利用Xib进行实现
应用场景:像团购网站的列表数据显示,新闻列表显示等(由于该类的显示的数据单元格内容格式相同)
(1)主控制器文件,在文件中实现了自己自定义的代理,加载数据,
1 #import "SLViewController.h" 2 #import "SLTgDatas.h" 3 #import "SLTableViewCell.h" 4 #import "SLFooterView.h" 5 #import "SLHeaderView.h" 6 7 @interface SLViewController ()8 9 @property (weak, nonatomic) IBOutlet UITableView *tableview;10 11 @property (nonatomic,strong) NSMutableArray *arrayM;12 13 @end14 15 @implementation SLViewController16 17 -(void)loadMoreData18 {19 NSLog(@"=======");20 SLTgDatas *da=[[SLTgDatas alloc] init];21 da.title=@"西红柿鸡蛋";22 da.price=@"12";23 da.buyCount=@"56";24 da.icon=@"2c97690e72365e38e3e2a95b934b8dd2";25 [self.arrayM addObject:da];26 [self.tableview reloadData];27 28 }29 30 31 #pragma mark -解析plist数据文件32 -(NSMutableArray *)arrayM33 {34 if (_arrayM==nil) {35 NSString *fullpath=[[NSBundle mainBundle] pathForResource:@"tgs" ofType:@"plist"];36 NSArray *array=[NSArray arrayWithContentsOfFile:fullpath];37 NSMutableArray *arr=[NSMutableArray arrayWithCapacity:array.count];38 for (NSDictionary *dict in array) {39 SLTgDatas *data=[SLTgDatas tgDataWithDiectionary:dict];40 [arr addObject:data];41 }42 43 _arrayM=arr;44 }45 46 return _arrayM;47 }48 49 - (void)viewDidLoad50 {51 [super viewDidLoad];52 // self.tableview.dataSource=self;53 54 UINib *nib=[UINib nibWithNibName:@"SLFooterView" bundle:nil];55 SLFooterView *footerview=[[nib instantiateWithOwner:nil options:nil] firstObject];56 self.tableview.tableFooterView=footerview;57 58 footerview.delegate=self;59 60 SLHeaderView *headerview=[SLHeaderView headerWithView];61 self.tableview.tableHeaderView=headerview;62 63 }64 65 #pragma mark -填充数据进行显示66 -(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView67 {68 return 1;69 }70 71 -(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section72 {73 return self.arrayM.count;74 }75 76 -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath77 {78 SLTableViewCell *cell=[SLTableViewCell cellWithTabelViewCell:tableView];79 SLTgDatas *data=self.arrayM[indexPath.row];80 cell.data=data;81 return cell;82 }83 84 #pragma mark -设置状态栏隐藏85 -(BOOL)prefersStatusBarHidden86 {87 return YES;88 }89 90 @end
(2)该文件是字典转对象模型文件
1 #import2 3 #import "SLGlobalCode.h" 4 5 @interface SLTgDatas : NSObject 6 7 @property (nonatomic,copy) NSString *title; 8 @property (nonatomic,copy) NSString *icon; 9 @property (nonatomic,copy) NSString *price;10 @property (nonatomic,copy) NSString *buyCount;11 12 @property (nonatomic,strong,readonly) UIImage *image;13 14 //SLTg(tg)15 -(instancetype)initWithTgDirectionary:(NSDictionary *)dict;16 17 +(instancetype)tgDataWithDiectionary:(NSDictionary *)dict;18 @end
1 #import "SLTgDatas.h" 2 3 @interface SLTgDatas () 4 { 5 UIImage *_image; 6 } 7 @end 8 9 @implementation SLTgDatas10 11 -(UIImage *)image12 {13 if (_image==nil) {14 _image=[UIImage imageNamed:self.icon];15 }16 return _image;17 }18 /**19 * 对代码进行抽取,成为其他地方也可以用这个方法20 */21 //SLTgRetrun(tg)22 -(instancetype)initWithTgDirectionary:(NSDictionary *)dict23 {24 if (self=[self init]) {25 [self setValuesForKeysWithDictionary:dict];26 }27 return self;28 }29 +(instancetype)tgDataWithDiectionary:(NSDictionary *)dict30 {31 return [[self alloc] initWithTgDirectionary:dict];32 }33 @end
(3)此文件是自定义cell对象,通过xib进行设计后,通过连线进行相关,方便控制器调用
1 #import2 3 #import "SLTgDatas.h" 4 5 @interface SLTableViewCell : UITableViewCell 6 7 @property (nonatomic,strong) SLTgDatas *data; 8 9 +(instancetype)cellWithTabelViewCell:(UITableView *)table;10 11 @end
#import "SLTableViewCell.h"@interface SLTableViewCell()@property (weak, nonatomic) IBOutlet UIImageView *cellImage;@property (weak, nonatomic) IBOutlet UILabel *celltitle;@property (weak, nonatomic) IBOutlet UILabel *cellprice;@property (weak, nonatomic) IBOutlet UILabel *cellbuycount;@end@implementation SLTableViewCell+(instancetype)cellWithTabelViewCell:(UITableView *)table{ static NSString *str=@"cell"; SLTableViewCell *cell=[table dequeueReusableCellWithIdentifier:str]; if (cell==nil) { cell=[[[NSBundle mainBundle] loadNibNamed:@"SLTgPlistView" owner:nil options:nil] firstObject]; } return cell;}-(void)setData:(SLTgDatas *)data{ _data=data; self.cellbuycount.text=data.buyCount; self.cellImage.image=data.image; self.cellprice.text=data.price; self.celltitle.text=data.title;}@end
(4)是底部加载更多选项
1 #import2 3 @protocol SLFooterViewDelegate 4 5 -(void)loadMoreData; 6 7 @end 8 9 @interface SLFooterView : UIView10 11 @property (nonatomic,weak) id delegate;12 @end
1 #import "SLFooterView.h" 2 @interface SLFooterView () 3 4 @property (weak, nonatomic) IBOutlet UIButton *clieckbt; 5 @property (weak, nonatomic) IBOutlet UIView *jiazai; 6 7 8 9 @end10 @implementation SLFooterView11 12 -(void)setDelegate:(id)delegate13 {14 _delegate=delegate;15 }16 17 - (IBAction)btnclick {18 self.clieckbt.hidden=YES;19 self.jiazai.hidden=NO;20 21 // dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(2.022 // * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{23 //24 // });25 // 26 dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(2.0 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{27 if ([self.delegate respondsToSelector:@selector(loadMoreData)])28 {29 [self.delegate loadMoreData];30 }31 self.clieckbt.hidden=NO;32 self.jiazai.hidden=YES;33 });34 35 36 }37 38 @end
以上就是利用xib进行设计的tableView进行显示的列表数据
综上所述:在自定义UITabelViewCell的时候,有两种方式,要根据不同的场景进行利用。
