使用SWTableViewCell得到ios7郵件中cell的右推出現選項的效果

SWTableViewCell 是託管在GitHub上的一個第三方UITableViewCell子類，它提供向左向右滑動出現「刪除」，「更多」等自定義UIButton的功能，該功能相似於iOS7中的郵件中的Cell。GitHub主頁： https://github.com/CEWendel/SWTableViewCell

 

Example:

場景：假如我如今要作一個TableView，它的cell就是SWTableViewCell的效果。 

 

ViewController.h

 

#import <UIKit/UIKit.h>
#import <SWTableViewCell.h>

@interface ViewController : UIViewController
<UITableViewDataSource,
UITableViewDelegate,
SWTableViewCellDelegate]]>

@property (nonatomic, strong) UITableView *tableView;

@end

 

ViewController.m

#import "ViewController.h"

@interface ViewController ()

@property (nonatomic, strong) NSMutableArray *dataArray;


@end

@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    [self initViews];
}

- (void)initViews
{
    
    _dataArray = [NSMutableArray arrayWithObjects:@"Shanghai",@"Beijing", @"Nanjing", @"Hangzhou",@"HongKong", @"Shenzhen", nil];
    _tableView = [[UITableView alloc] initWithFrame:CGRectMake(0, 0, 320, 640)];
    _tableView.delegate = self;
    _tableView.dataSource  = self;
    [self.view addSubview:_tableView];
}


#prama mark - UITableViewDelegate
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *cellIdentifier = @"Cell";
    
    SWTableViewCell *cell = (SWTableViewCell *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier];
    
    if (cell == nil) {
        cell = [[SWTableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:cellIdentifier];
        cell.leftUtilityButtons = [self leftButtons];
        cell.rightUtilityButtons = [self rightButtons];
        cell.delegate = self;
    }
    
    cell.textLabel.text = _dataArray[indexPath.row];
    
    return cell;
    
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return 4;
}


- (NSArray *)rightButtons
{
    NSMutableArray *rightUtilityButtons = [NSMutableArray new];
    [rightUtilityButtons sw_addUtilityButtonWithColor:
     [UIColor colorWithRed:0.78f green:0.78f blue:0.8f alpha:1.0]
                                                title:@"More"];
    [rightUtilityButtons sw_addUtilityButtonWithColor:
     [UIColor colorWithRed:1.0f green:0.231f blue:0.188 alpha:1.0f]
                                                title:@"Delete"];
    
    return rightUtilityButtons;
}

- (NSArray *)leftButtons
{
    NSMutableArray *leftUtilityButtons = [NSMutableArray new];
    
    [leftUtilityButtons sw_addUtilityButtonWithColor:
     [UIColor colorWithRed:0.07 green:0.75f blue:0.16f alpha:1.0]
                                                title:@"Left1"];
    [leftUtilityButtons sw_addUtilityButtonWithColor:
     [UIColor colorWithRed:1.0f green:1.0f blue:0.35f alpha:1.0]
                                                title:@"Left2"];
    [leftUtilityButtons sw_addUtilityButtonWithColor:

                                                title:@"Left3"];
    [leftUtilityButtons sw_addUtilityButtonWithColor:
     [UIColor colorWithRed:0.55f green:0.27f blue:0.07f alpha:1.0]
                                                title:@"Left4"];
    return leftUtilityButtons;
}


#pragma mark - SWTableViewDelegate

    switch (index) {
        case 0:
            NSLog(@"check button was pressed");
            break;
        case 1:
            NSLog(@"clock button was pressed");
            break;
        case 2:

            break;
        case 3:

}

    [super didReceiveMemoryWarning];
}

@end

 

效果：

 

 

注意：1. 若是要在自定義的TableViewCell中使用SWTableViewCell， 在向swTableViewCell 中添加組件的時候，須要使用swTableViewCell.contentView addSubview: 方法，不然，在向左或者向右滑動的時候，添加的組件不會隨之滑動。
         2. 若是須要改變SWTableViewCell的高度，須要使用setCellHeight方法，而若是僅僅使用swTableViewCell.frame = CGRectMake(,,,);的方法設置高度時，它的button的高度將不會改變。
