使用SWTableViewCell获得ios7邮件中cell的右推出现选项的效果

SWTableViewCell 是托管在GitHub上的一个第三方UITableViewCell子类，它提供向左向右滑动出现“删除”，“更多”等自定义UIButton的功能，该功能类似于iOS7中的邮件中的Cell。GitHub主页： https://github.com/CEWendel/SWTableViewCell

 
Example:
场景：假如我现在要做一个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:     [UIColor colorWithRed:1.0f green:0.231f blue:0.188f alpha:1.0]                                                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- (void)swipeableTableViewCell:(SWTableViewCell *)cell didTriggerLeftUtilityButtonWithIndex:(NSInteger)index {    switch (index) {        case 0:            NSLog(@"check button was pressed");            break;        case 1:            NSLog(@"clock button was pressed");            break;        case 2:            NSLog(@"cross button was pressed");            break;        case 3:            NSLog(@"list button was pressed");        default:            break;    }}- (void)swipeableTableViewCell:(SWTableViewCell *)cell didTriggerRightUtilityButtonWithIndex:(NSInteger)index {    switch (index) {        case 0:            NSLog(@"More button was pressed");            break;        case 1:        {            NSLog(@"Delete button was pressed");        }        default:            break;    }}- (void)didReceiveMemoryWarning{    [super didReceiveMemoryWarning];}@end

 

效果：
 

 

注意!： 如果要在自定义的TableViewCell中使用SWTableViewCell， 在向swTableViewCell 中添加组件的时候，需要使用swTableViewCell.contentView addSubview: 方法，否则，在向左或者向右滑动的时候，添加的组件不会随之滑动。
