Question

我正在使用UITableview进行反馈，即使用自定义复选框进行选择。在UITableviewcell中，我为四个选项放置了四个静态按钮，例如，好，好，平均值，低于平均值。

我要的是，我只想选择连续选中的一个按钮，如果我自动选择了另一个按钮，则应该取消选中先前选择的按钮。

示例：在同一行中，假设如果我再次选择非常好，又选择了平均值，则应取消选中先前选择的非常好。< / p>

在下面检查我的代码以供参考：

这在cellforrowatindexpath中

[cell.R1_BTN setImage:[UIImage imageNamed:@"Touch_G.png"] forState:UIControlStateNormal];
[cell.R1_BTN addTarget:self action:@selector(BtnClicked:) forControlEvents:UIControlEventTouchUpInside]; 
cell.R1_BTN.tag=1;

点击事件在这里。

-(void)BtnClicked:(id)sender
{
//Need Code Here..
}

更新的代码以供参考。

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
   return [GNM count];
}

-(UITableViewCell *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
{
   return  [GNM objectAtIndex:section];
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
   if ([[NM objectAtIndex:section] isKindOfClass:[NSArray class]])
   {
     return [[NM objectAtIndex:section] count];
   }
   else
   {
     return 1;
   }

}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
 FeedBackFormTVC *cell = [FeedBack_TV dequeueReusableCellWithIdentifier:@"ListCell" forIndexPath:indexPath];

cell.FBName_LBL.text = [[NM objectAtIndex:indexPath.section] isKindOfClass:[NSArray class]]
? [[NM objectAtIndex:indexPath.section] objectAtIndex:indexPath.row]
: [NM objectAtIndex:indexPath.section];

// below for assigning code action event..
....
....
...

}

我尝试使用标签，但是我没有得到想要的东西，请帮我..谢谢提前。

Answer 1

我认为您应该使用模型来设置UITableViewCell。您模型的.h文件，例如：

%td

.m文件，例如：

#import <Foundation/Foundation.h>

typedef enum : NSInteger {
    UNKNOWN = 0,
    VERY_GOOD = 1,
    GOOD = 2,
    AVERAGE = 3,
    BELOW_AVERAGE = 4
}RangeMark;

@interface CellModel : NSObject

@property(nonatomic, assign)    RangeMark range;

@end

比您应该使用.xib文件初始化一个表格单元格看起来像：

及其.h文件，如：

#import "CellModel.h"

@implementation CellModel

@end

其.m文件，例如：

#import <UIKit/UIKit.h>
#import "CellModel.h"

@interface TableViewCell : UITableViewCell

@property (weak, nonatomic) IBOutlet UIButton *veryGoodButton;
@property (weak, nonatomic) IBOutlet UIButton *goodButton;
@property (weak, nonatomic) IBOutlet UIButton *averageButton;
@property (weak, nonatomic) IBOutlet UIButton *belowAverageButton;

- (void)setupCellWithModel:(CellModel*)model;

@end

最后，您的视图控制器.h文件应如下所示：

#import "TableViewCell.h"

@implementation TableViewCell

- (void)awakeFromNib {
    [super awakeFromNib];
    // Initialization code
}

- (void)setSelected:(BOOL)selected animated:(BOOL)animated {
    [super setSelected:selected animated:animated];

    // Configure the view for the selected state
}

- (void)setupCellWithModel:(CellModel *)model {

    if(model.range == VERY_GOOD) {
        self.veryGoodButton.backgroundColor = [UIColor greenColor];
    }
    else if(model.range == GOOD) {
        self.goodButton.backgroundColor = [UIColor blueColor];
    }
    else if(model.range == AVERAGE) {
        self.averageButton.backgroundColor = [UIColor yellowColor];
    }
    else if(model.range == BELOW_AVERAGE) {
        self.belowAverageButton.backgroundColor = [UIColor redColor];
    }
}

- (void)prepareForReuse {
    [super prepareForReuse];
    self.veryGoodButton.backgroundColor = [UIColor lightGrayColor];
    self.goodButton.backgroundColor = [UIColor lightGrayColor];
    self.averageButton.backgroundColor = [UIColor lightGrayColor];
    self.belowAverageButton.backgroundColor = [UIColor lightGrayColor];
}

@end

和.m文件应如下所示：

#import <UIKit/UIKit.h>
#import "TableViewCell.h"

@interface ViewController : UIViewController

@property (weak, nonatomic) IBOutlet UITableView *tableView;

@end

仅此而已：）

最终，应用程序如下：

Answer 2

是的，这将为您提供解决方案，至少我希望这样：）

首先创建一个自定义按钮.h文件，如下所示：

#import <UIKit/UIKit.h>

@interface CustomButton : UIButton

@property (assign) NSInteger sectionTag;
@property (assign) NSInteger rowTag;

@end

自定义按钮.m文件如下：

#import "CustomButton.h"

@implementation CustomButton

/*
// Only override drawRect: if you perform custom drawing.
// An empty implementation adversely affects performance during animation.
- (void)drawRect:(CGRect)rect {
    // Drawing code
}
*/

@end

然后我像这样更改TableViewCell .h文件中的一些内容：

#import <UIKit/UIKit.h>
#import "CellModel.h"
#import "CustomButton.h"

@interface TableViewCell : UITableViewCell

@property (weak, nonatomic) IBOutlet CustomButton *veryGoodButton;
@property (weak, nonatomic) IBOutlet CustomButton *goodButton;
@property (weak, nonatomic) IBOutlet CustomButton *averageButton;
@property (weak, nonatomic) IBOutlet CustomButton *belowAverageButton;
@property (weak, nonatomic) IBOutlet UILabel *itemLabel;

- (void)setupCellWithModel:(CellModel*)model;

@end

TableViewCell .m文件如下：

#import "TableViewCell.h"

@implementation TableViewCell

- (void)awakeFromNib {
    [super awakeFromNib];
    // Initialization code
}

- (void)setSelected:(BOOL)selected animated:(BOOL)animated {
    [super setSelected:selected animated:animated];

    // Configure the view for the selected state
}

- (void)setupCellWithModel:(CellModel *)model {

    if(model.range == VERY_GOOD) {
        self.veryGoodButton.backgroundColor = [UIColor greenColor];
    }
    else if(model.range == GOOD) {
        self.goodButton.backgroundColor = [UIColor blueColor];
    }
    else if(model.range == AVERAGE) {
        self.averageButton.backgroundColor = [UIColor yellowColor];
    }
    else if(model.range == BELOW_AVERAGE) {
        self.belowAverageButton.backgroundColor = [UIColor redColor];
    }

    [self.itemLabel setText:model.itemText];
}

- (void)prepareForReuse {
    [super prepareForReuse];
    self.veryGoodButton.backgroundColor = [UIColor lightGrayColor];
    self.goodButton.backgroundColor = [UIColor lightGrayColor];
    self.averageButton.backgroundColor = [UIColor lightGrayColor];
    self.belowAverageButton.backgroundColor = [UIColor lightGrayColor];
}

及其.xib如下：

另一方面，像这样的CellModel .h文件只有一个更改：

#import <Foundation/Foundation.h>

typedef enum : NSInteger {
    UNKNOWN = 0,
    VERY_GOOD = 1,
    GOOD = 2,
    AVERAGE = 3,
    BELOW_AVERAGE = 4
}RangeMark;

@interface CellModel : NSObject

@property(nonatomic, assign)    RangeMark range;
@property(nonatomic, copy)      NSString* itemText;

- (id)initWith:(NSString*)itemText withRangeMark:(RangeMark)range;

@end

及其.m文件是这样的：

#import "CellModel.h"

@implementation CellModel

- (id)initWith:(NSString*)itemText withRangeMark:(RangeMark)range {
    self = [super init];
    if(self) {
        self.itemText = itemText;
        self.range = range;
    }
    return self;
}

@end

最终查看控制器.h文件相同，但.m像这样：

#import "ViewController.h"

@interface ViewController () <UITableViewDelegate, UITableViewDataSource>{
    NSMutableArray *modelList;
    NSMutableArray<NSString*> *sectionTitleList;
}

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    self.tableView.estimatedRowHeight = 600;
    self.tableView.rowHeight = UITableViewAutomaticDimension;

    sectionTitleList = [NSMutableArray<NSString*> new];
    [sectionTitleList addObject:@"RESERVATION"];
    [sectionTitleList addObject:@"FRONT DESK"];
    [sectionTitleList addObject:@"CASHIER"];
    [sectionTitleList addObject:@"HOUSE KEEPING"];

    modelList = [[NSMutableArray alloc] initWithCapacity: 4];

    [modelList insertObject:[NSMutableArray arrayWithObjects:[[CellModel alloc] initWith:@"Service Speed" withRangeMark:UNKNOWN],[[CellModel alloc] initWith:@"Good Speed" withRangeMark:UNKNOWN],[[CellModel alloc] initWith:@"Confirmation Quality" withRangeMark:UNKNOWN],[[CellModel alloc] initWith:@"Quick Service in Reservetion" withRangeMark:UNKNOWN],nil] atIndex:0];

    [modelList insertObject:[NSMutableArray arrayWithObjects:[[CellModel alloc] initWith:@"Check In" withRangeMark:UNKNOWN],[[CellModel alloc] initWith:@"Happy on Their Service" withRangeMark:UNKNOWN],[[CellModel alloc] initWith:@"Coutesey" withRangeMark:UNKNOWN],[[CellModel alloc] initWith:@"Quick Service at Check In" withRangeMark:UNKNOWN],nil] atIndex:1];

    [modelList insertObject:[NSMutableArray arrayWithObjects:[[CellModel alloc] initWith:@"Front Office & Reception" withRangeMark:UNKNOWN],[[CellModel alloc] initWith:@"Overall Quality of Room" withRangeMark:UNKNOWN],[[CellModel alloc] initWith:@"Check" withRangeMark:UNKNOWN],[[CellModel alloc] initWith:@"Response Time" withRangeMark:UNKNOWN],nil] atIndex:2];

    [modelList insertObject:[NSMutableArray arrayWithObjects:[[CellModel alloc] initWith:@"Room Decor" withRangeMark:UNKNOWN],nil] atIndex:3];


//    [modelList addObject: [[CellModel alloc] initWith:@"Service Speed" withRangeMark:UNKNOWN]];
//    [modelList addObject: [[CellModel alloc] initWith:@"Good Speed" withRangeMark:UNKNOWN]];
//    [modelList addObject: [[CellModel alloc] initWith:@"Confirmation Quality" withRangeMark:UNKNOWN]];
//    [modelList addObject: [[CellModel alloc] initWith:@"Quick Service in Reservetion" withRangeMark:UNKNOWN]];

//    for (int i=0; i<5; i++) {
//        CellModel *cellModel = [[CellModel alloc] init];
//        cellModel.range = UNKNOWN;
//        cellModel.itemText = @"";

我认为它将对您很好。只需将代码上的数组初始化部分更改为动态：）

最后一次出现：

Answer 3

class uploadfileform(forms.ModelForm):
    class Meta:
        model=uploadfolder
        fields=('File_to_upload',)

也许这可以帮助您。

Answer 4

由于您没有按要求提供API响应详细信息，因此我们被迫使用静态值。请从数组API响应中替换sectionTitleList和modelList。请找到下面的代码，用于将您的API响应分配给@GökhanAydın创建的模型。

sectionTitleList = @[@"RESERVATION",@"FRONT DESK",@"CASHIER",@"HOUSE KEEPING",@"COMMON"];
    modelList = @[
                 @[
                  @"Service Speed",
                  @"Good Service",
                  @"Confirmation quality",
                  @"Quick Service in Reservation"
                  ],
                 @[
                  @"Check In",
                  @"Happy on their Service",
                  @"Courtesey",
                  @"Quick Service at Checkin"
                  ],
                 @[
                  @"Front office & reception",
                  @"Overall Quality of Room",
                  @"Check",
                  @"Response time"
                  ],
                 @[
                  @"Room Decor",
                  @"Time taken to serveTime taken to serveTime taken t",
                  @"Bathroom",
                  @"Facilities in the Room",
                  @"Choice of menu",
                  @"Housekeeping",
                  @"Room Service"
                  ],
                 @[
                  @"Overall Comments",
                  @"Will you come back again"
                  ]
                 ];

        self.navigationItem.title = [modelList lastObject];
GNM = [sectionTitleList mutableCopy];
NM = [[NSMutableArray alloc]init];
for (NSArray *feedbacktitles in modelList) {
    if ([feedbacktitles isKindOfClass:[NSArray class]]) {
        __block NSMutableArray *tempArray = [NSMutableArray new];
        [feedbacktitles enumerateObjectsUsingBlock:^(NSString *title, NSUInteger idx, BOOL * _Nonnull stop) {
            FeedbackModel *model = [[FeedbackModel alloc]initWith:title withRangeMark:UNKNOWN];
            [tempArray addObject:model];
            if (idx ==  [feedbacktitles count] - 1 ) {
                *stop = TRUE;
                [self->NM addObject:tempArray];
                tempArray = [NSMutableArray new];
            }
        }];

    }
}

或通过简单的for循环

for (NSArray *feedbacktitles in modelList) {
        NSLog(@"%@",feedbacktitles);
        NSMutableArray* rowStringArray = [NSMutableArray new];
        if ([feedbacktitles isKindOfClass:[NSArray class]]) {
            for(int i = 0; i < [feedbacktitles count]; i++) {
                NSString* rowTitle = [feedbacktitles objectAtIndex:i];
                FeedbackModel *model = [[FeedbackModel alloc]initWith:rowTitle withRangeMark:UNKNOWN];
                [rowStringArray addObject: model];
                if (i == [feedbacktitles count] - 1) {
                    [NM addObject: rowStringArray];
                    rowStringArray = [NSMutableArray new];
                }
            }
        }
    }
