前言: 本篇博客其實就是想介紹tableviewcell滑動的一些"事",昨天在逛github的時候看到的還挺有意思的三方庫,簡單用了一下感覺不錯,一作為記錄,二是希望有類似需求的可以得到幫助。
本篇介紹了iOS 5之後(使用三方庫) iOS 8之後(系統方法)分別的實現方式

效果圖 - ios>= 5.0

效果圖 - ios>= 8.0
MGSwipeTableCell(Github上的三方庫)- iOS >= 5.0
直接使用比較簡單 通過代碼看一下
首先簽這個協議MGSwipeTableCellDelegate
添加左邊按鈕方法
- (NSArray *)btnLeftCount:(int)count
{
NSMutableArray *result = [NSMutableArray array];
UIColor *colors[3] = {[UIColor greenColor],
[UIColor colorWithRed:0 green:0x99/255.0 blue:0xcc/255.0 alpha:1.0],
[UIColor colorWithRed:0.59 green:0.29 blue:0.08 alpha:1.0]};;
for (int i = 0; i < count; i ++) {
// 按鈕提供了幾個方法, 可以點進去看一看
MGSwipeButton *btn = [MGSwipeButton buttonWithTitle:@"" backgroundColor:colors[i] padding:15 callback:^BOOL(MGSwipeTableCell *sender) {
return YES;
}];
// 把按鈕加到數組中
[result addObject:btn];
}
return result;
}添加右邊按鈕的方法
- (NSArray *)btnRightCount:(int)count
{
NSMutableArray *result = [NSMutableArray array];
NSArray *titleArray = @[@"刪除", @"標記未讀"];
UIColor *color[2] = {[UIColor redColor], [UIColor lightGrayColor]};
for (int i = 0; i < count; i ++) {
MGSwipeButton *btn = [MGSwipeButton buttonWithTitle:titleArray[i] backgroundColor:color[i] padding:15 callback:^BOOL(MGSwipeTableCell *sender) {
BOOL autoHide = i != 0;
return autoHide;
}];
// 把按鈕加到數組中
[result addObject:btn];
}
return result;
}重用池可以這樣寫
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellID = @"cellId";
// 這裡如果MGSwipeTableCell是足夠你使用的, 你可以直接使用
// 或者自定義創建cell繼承於MGSwipeTableCell, 像我下面代碼這樣
XTCustomCell *cell = [tableView dequeueReusableCellWithIdentifier:cellID];
if (!cell) {
cell = [[XTCustomCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:cellID];
}
cell.label.text = [NSString stringWithFormat:@"%ld------%@", (long)indexPath.row, self.arrayTest[indexPath.row]];
cell.label.font = [UIFont systemFontOfSize:20];
// 指定代理人
cell.delegate = self;
// NO: 只有單個可以滑動 , YES: 多個可以滑動
cell.allowsMultipleSwipe = NO;
return cell;
}添加按鈕
-(NSArray*) swipeTableCell:(MGSwipeTableCell*) cell swipeButtonsForDirection:(MGSwipeDirection)direction
swipeSettings:(MGSwipeSettings*) swipeSettings expansionSettings:(MGSwipeExpansionSettings*) expansionSettings;
{
if (direction == MGSwipeDirectionRightToLeft) {
return [self btnRightCount:2];
}
else {
return [self btnLeftCount:3];
}
}按鈕的點擊代理方法
-(BOOL) swipeTableCell:(MGSwipeTableCell*) cell tappedButtonAtIndex:(NSInteger) index direction:(MGSwipeDirection)direction fromExpansion:(BOOL) fromExpansion
{
switch (direction) {
case MGSwipeDirectionLeftToRight: {
if (index == 0) {
NSLog(@"right ------- 0");
}else{
NSLog(@"right ------- 1");
}
break;
}
case MGSwipeDirectionRightToLeft: {
if (index == 0) {
NSLog(@"left ------- 0");
// 這裡簡單的做了個刪除操作
NSIndexPath * path = [_tableView indexPathForCell:cell];
[_arrayTest removeObjectAtIndex:path.row];
[_tableView deleteRowsAtIndexPaths:@[path] withRowAnimation:UITableViewRowAnimationLeft];
return NO;
}else{
NSLog(@"left ------- 1");
}
break;
}
}
return YES;
}iOS 8之後也提供了類似的實現
- (NSArray*)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewRowAction *deleteRowAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDestructive title:@"刪除" handler:^(UITableViewRowAction * _Nonnull action, NSIndexPath * _Nonnull indexPath) { [self.arrayTest removeObjectAtIndex:indexPath.row]; [self.tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic]; }]; UITableViewRowAction *topRowAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:@"置頂" handler:^(UITableViewRowAction * _Nonnull action, NSIndexPath * _Nonnull indexPath) { [self.arrayTest exchangeObjectAtIndex:indexPath.row withObjectAtIndex:0]; NSIndexPath *firstIndexPath = [NSIndexPath indexPathForRow:0 inSection:indexPath.section]; [tableView moveRowAtIndexPath:indexPath toIndexPath:firstIndexPath]; }]; topRowAction.backgroundColor = [UIColor blueColor]; UITableViewRowAction *moreRowAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleNormal title:@"更多" handler:^(UITableViewRowAction * _Nonnull action, NSIndexPath * _Nonnull indexPath) { [self.tableView reloadRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationMiddle]; }]; return @[deleteRowAction,topRowAction,moreRowAction]; }
