iOS 封裝tableview,實用例子彙總

大家不同的程序的時候可能經常遇到類似的tableview。很簡單，但是又很繁瑣，這時候封裝一個自己常用的tableview也不失爲一個良方，充分的節約自己的時間。

@interface AppSettingVC ()

@end

@implementation AppSettingVC

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.

去掉多餘的分割線

plain類型的tableview當顯示的數據很少時，下面的cell即使不顯示數據也會有分割線，可以通過下面這個函數去掉多餘的分割線。

• (void)setExtraCellLineHidden: (UITableView *)tableView

{

UIView *view =[ [UIView alloc]init];

view.backgroundColor = [UIColor clearColor];

[tableView setTableFooterView:view];

[view release];

}

當tableview的dataSource爲空時，也就是沒有數據可顯示時，該方法無效，只能在numberOfRowsInsection函數，通過判斷dataSouce的數據個數，如果爲零可以將tableview的separatorStyle設置爲UITableViewCellSeparatorStyleNone去掉分割線，然後在大於零時將其設置爲
UITableViewCellSeparatorStyleSingleLine（驗證發現不用單獨設置）

如何獲取點擊的是哪個tableViewCell上的Button按鈕

1.首先把cell上button按鈕的點擊方法寫入在cell展示裏面

//cell展示
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
    PraiseListCell *cell = [tableView dequeueReusableCellWithIdentifier:@"PraiseListCell" forIndexPath:indexPath];
    //重點
    [cell.attentionClickButton addTarget:self action:@selector(onTouchBtnInCell:) forControlEvents:(UIControlEventTouchUpInside)];
    return cell;
}

2.在button按鈕的點擊方法裏面實現

- (void)onTouchBtnInCell:(UIButton *)sender {
    CGPoint point = sender.center;
    point = [self.tableView convertPoint:point fromView:sender.superview];
    NSIndexPath* indexpath = [self.tableView indexPathForRowAtPoint:point];
    NSLog(@"%ld",(long)indexpath.row);
}

3.能拿到點擊的indexpath，我們就可以操作數據、數組、做自己要的東西了
