为什么在重新加载目标c中的表视图时，所选值将被取消select
我是iOS新手，在自定义表格视图中遇到问题。 我正在使用自定义表格视图单元格

如图片中我select传递button
但是当我重新加载表selectbutton取消select
我怎样才能得到选定的价值，当我重新加载表。感谢提前！
在ios表格视图重用每行的单元格，所以它确实发生。 您使用模型类来pipe理select。 我在单元格上的button上添加了select器。还有重载表格视图的例子。 请检查下面的代码。
// // ViewController.m #import "ViewController.h" #import "DataModel.h" #import "MyTableViewCell.h" @interface ViewController () { NSMutableArray *arrData; } @end @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; arrData = [[NSMutableArray alloc]init]; // create 15 model and store in array for (int i =0; i<15; i++) { DataModel *model = [DataModel new]; model.strSelected = @""; [arrData addObject:model]; } } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return arrData.count; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { MyTableViewCell *cell = [self.tblView dequeueReusableCellWithIdentifier:@"cell" forIndexPath:indexPath]; // tag add on buttons cell.btnPPressed.tag = indexPath.row; cell.btnFPressed.tag = indexPath.row; cell.btnWPressed.tag = indexPath.row; cell.btnNAPressed.tag = indexPath.row; //method add on buttons [cell.btnPPressed addTarget:self action:@selector(btnP:) forControlEvents:UIControlEventTouchUpInside]; [cell.btnFPressed addTarget:self action:@selector(btnF:) forControlEvents:UIControlEventTouchUpInside]; [cell.btnWPressed addTarget:self action:@selector(btnW:) forControlEvents:UIControlEventTouchUpInside]; [cell.btnNAPressed addTarget:self action:@selector(btnNA:) forControlEvents:UIControlEventTouchUpInside]; //background color change on button DataModel *model = [arrData objectAtIndex:indexPath.row]; if([model.strSelected isEqualToString:@"P"]) { cell.btnPPressed.backgroundColor = [UIColor redColor]; } else if([model.strSelected isEqualToString:@"F"]) { cell.btnFPressed.backgroundColor = [UIColor redColor]; } else if([model.strSelected isEqualToString:@"W"]) { cell.btnWPressed.backgroundColor = [UIColor redColor]; } else if([model.strSelected isEqualToString:@"NA"]) { cell.btnNAPressed.backgroundColor = [UIColor redColor]; } else { cell.btnPPressed.backgroundColor = [UIColor darkGrayColor]; cell.btnFPressed.backgroundColor = [UIColor darkGrayColor]; cell.btnWPressed.backgroundColor = [UIColor darkGrayColor]; cell.btnNAPressed.backgroundColor = [UIColor darkGrayColor]; } return cell; } //buttons methods -(void)btnP:(UIButton *)sender { sender.backgroundColor = [UIColor redColor]; DataModel *model = [arrData objectAtIndex:sender.tag]; model.strSelected = @"P"; //example reload table dispatch_async(dispatch_get_main_queue(), ^{ [self.tblView reloadData]; }); } -(void)btnF:(UIButton *)sender { sender.backgroundColor = [UIColor redColor]; DataModel *model = [arrData objectAtIndex:sender.tag]; model.strSelected = @"F"; //example reload table dispatch_async(dispatch_get_main_queue(), ^{ [self.tblView reloadData]; }); } -(void)btnW:(UIButton *)sender { sender.backgroundColor = [UIColor redColor]; DataModel *model = [arrData objectAtIndex:sender.tag]; model.strSelected = @"W"; //example reload table dispatch_async(dispatch_get_main_queue(), ^{ [self.tblView reloadData]; }); } -(void)btnNA:(UIButton *)sender { sender.backgroundColor = [UIColor redColor]; DataModel *model = [arrData objectAtIndex:sender.tag]; model.strSelected = @"NA"; //example reload table dispatch_async(dispatch_get_main_queue(), ^{ [self.tblView reloadData]; }); } @end // DataModel.h #import <Foundation/Foundation.h> @interface DataModel : NSObject @property(nonatomic, strong)NSString *strSelected; @end // MyTableViewCell.h #import <UIKit/UIKit.h> @interface MyTableViewCell : UITableViewCell @property (strong, nonatomic) IBOutlet UIButton *btnPPressed; @property (strong, nonatomic) IBOutlet UIButton *btnFPressed; @property (strong, nonatomic) IBOutlet UIButton *btnWPressed; @property (strong, nonatomic) IBOutlet UIButton *btnNAPressed; @end
要很多代码….你应该只发布有关问题的代码。 我的猜测，你只设置视图，没有variables负责这一点。 重新加载表格视图时，您将更新颜色并设置默认颜色。 简单的解决scheme – 创build代表每个细胞的模型。 这个模型知道哪些button被选中
编辑：例子
class Model { var name: String? var isButtonOneSelected = false var isButtonTwoSelected = false var isButtonThreeSelected = false .... }
你可以有一个模型或一个可变的字典来表示select你的button。
NSMutableDictionary *buttonSelection = [@{@"P_Button" : @"Selected", @"F_Button" : @"Selected", @"W_Button" : @"Selected", @"NA_Button" : @"Selected"} mutableCopy];
在你的方法cellForRowAtIndexPath里面。 你可以简单地使用这个字典来更新每个单元格：
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *STI=@"STI"; AuditTableViewCell *cell = (AuditTableViewCell *)[tableView dequeueReusableHeaderFooterViewWithIdentifier:STI]; if (cell == nil) { NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"AuditTableViewCell" owner:self options:nil]; cell = [nib objectAtIndex:0]; cell.accessoryType=UITableViewCellAccessoryNone; } if ([[buttonSelection objectForKey:@"P_Button"] isEqualToString:@"Selected"]) { [cell.passbtn setSelected:YES]; } return cell; }
除此之外，最好还是使用自定义单元格的代理模式来获得所需的function。 这可以通过以下方式完成。
@protocol CustomCellProtocol <NSObject> - (void)passButtonSelected:(BOOL)selected forIndexPath:(NSIndexPath *)indexPath; @end @interface CustomTableViewCell : UITableViewCell @property (nonatomic, weak) id<CustomCellProtocol> cellDelegate; @property (nonatomic) NSIndexPath *indexPath; @end
在@implementation或.m文件中，单击button，执行以下操作
- (void)passButtonSelected { [self.cellDelegate passButtonSelected:YES forIndexPath:self.indexPath]; }
在你的cellForRowAtIndexPath方法里面，
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *STI=@"STI"; AuditTableViewCell *cell = (AuditTableViewCell *)[tableView dequeueReusableHeaderFooterViewWithIdentifier:STI]; if (cell == nil) { NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"AuditTableViewCell" owner:self options:nil]; cell = [nib objectAtIndex:0]; cell.accessoryType=UITableViewCellAccessoryNone; } cell.indexPath = indexPath; cell.cellDelegate = self; if ([[buttonSelection objectForKey:@"P_Button"] isEqualToString:@"Selected"]) { [cell.passbtn setSelected:YES]; } return cell; }
所以，当你点击你的单元格上的button。 您将在您的tableview.m文件中获得以下电话。
- (void)passButtonSelected:(BOOL)selected forIndexPath:(NSIndexPath *)indexPath { NSMutableDictionary *statusDic = [[self.buttonStatusModelArray objectAtIndex:indexPath.row] mutableCopy]; [statusDic setObject:(selected ? @"Selected" : @"NonSelected") forKey:@"P_Button"]; [self.buttonStatusModelArray replaceObjectAtIndex:indexPath.row withObject:statusDic]; }
如果您在实施过程中遇到任何问题，请告诉我。 随意build议编辑，使这个更好:)
