代码实现仿支付宝cell拖动排序

代码如下:

p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 14.0px Monaco; color: #e44448}p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 14.0px Monaco; color: #ffffff; min-height: 19.0px}p.p3 {margin: 0.0px 0.0px 0.0px 0.0px; font: 14.0px Monaco; color: #00afca}p.p4 {margin: 0.0px 0.0px 0.0px 0.0px; font: 14.0px Monaco; color: #ffffff}p.p5 {margin: 0.0px 0.0px 0.0px 0.0px; font: 14.0px Monaco; color: #c2349b}p.p6 {margin: 0.0px 0.0px 0.0px 0.0px; font: 14.0px Monaco; color: #4cbf57}p.p7 {margin: 0.0px 0.0px 0.0px 0.0px; font: 14.0px Monaco; color: #93c86a}span.s1 {font-variant-ligatures: no-common-ligatures; color: #d28f5a}span.s2 {font-variant-ligatures: no-common-ligatures}span.s3 {font-variant-ligatures: no-common-ligatures; color: #c2349b}span.s4 {font-variant-ligatures: no-common-ligatures; color: #ffffff}span.s5 {font-variant-ligatures: no-common-ligatures; color: #93c86a}span.s6 {font-variant-ligatures: no-common-ligatures; color: #00afca}span.s7 {font: 14.0px 'PingFang SC'; font-variant-ligatures: no-common-ligatures}span.s8 {font-variant-ligatures: no-common-ligatures; color: #e44448}span.s9 {font-variant-ligatures: no-common-ligatures; color: #8b84cf}

#import "ViewController.h"

@interface ViewController ()
{
    UITableView *mainTable;
    NSMutableArray *tableData;
}

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    
    self.view.backgroundColor = [UIColor whiteColor];
    self.title = @"拖动cell排序";
    
    self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemEdit target:self action:@selector(edit)];

    tableData = [[NSMutableArray alloc] initWithObjects:@"1",@"2",@"3",@"4",@"5",@"6",@"7", nil];
    
}

- (void)edit
{
    [mainTable setEditing:!mainTable.editing animated:YES];
}

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return tableData.count;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSString *cellId = [NSString stringWithFormat:@"%ld%ld",(long)indexPath.section,(long)indexPath.row];
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellId];
    if (!cell)
    {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellId];
    }
    
    cell.textLabel.text = [tableData objectAtIndex:indexPath.row];
    
    return cell;
}

-(UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath
{
    return UITableViewCellEditingStyleNone;
}

- (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)fromIndexPath toIndexPath:(NSIndexPath *)toIndexPath
{
    [tableData exchangeObjectAtIndex:fromIndexPath.row withObjectAtIndex:toIndexPath.row];
}

 /** 拖动排序 此方法只对 group类型有效 */
-(BOOL)tableView:(UITableView *)tableView shouldIndentWhileEditingRowAtIndexPath:(NSIndexPath *)indexPath
{
    return NO;
}

- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath
{
    return YES;
}

- (BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath
{
    return YES;
}

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    return 45.0f;
}

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
    return 15.0f;
}

- (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section
{
    return 0.1f;
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    [tableView deselectRowAtIndexPath:indexPath animated:YES];
}
- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

@end

注意：实现拖动排序的关键是设置 -(BOOL)tableView:(UITableView *)tableView shouldIndentWhileEditingRowAtIndexPath:(NSIndexPath *)indexPath 方法返回NO,tableViewCell 默认属性为YES
