我是ios的新手,如何在uitableview中更新进度条。一般我有一个按钮,当我点击特定单元格中的按钮时,我需要在该单元格中显示进度条,请帮助我并提前致谢
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = @"Categorycell";
Categorycell *cell = (Categorycell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"Categorycell" owner:self options:nil];
cell = [nib objectAtIndex:0];
}
[tableView setSeparatorColor:[UIColor clearColor]];- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = @"Categorycell";
Categorycell *cell = (Categorycell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"Categorycell" owner:self options:nil];
cell = [nib objectAtIndex:0];
}
[tableView setSeparatorColor:[UIColor clearColor]];
cell.selectionStyle=UITableViewCellSelectionStyleNone;
NSLog(@"Index : %d",indexPath.row);
NSString *str_filepath=[thumbnails objectAtIndex:indexPath.row];
cell.cell_img.image=[[UIImage alloc]initWithContentsOfFile:str_filepath];
cell.title.text=[arr_book objectAtIndex:indexPath.row];
cell.sub_title.text=[arr_gen objectAtIndex:indexPath.row];
NSString *str_rating=[arr_rating objectAtIndex:indexPath.row];
int val_rating=[str_rating integerValue];
// cell.cell_btn.hidden=YES;
cell.cell_btn.tag = indexPath.row*10+1;
[cell.cell_btn addTarget:self action:@selector(btnDown:) forControlEvents:UIControlEventTouchUpInside];
cell.cell_ReadBtn.tag =indexPath.row*10+1;
[cell.cell_ReadBtn addTarget:self action:@selector(btnRead:) forControlEvents:UIControlEventTouchUpInside];
cell.cell_Progress.tag= indexPath.row*10+1;
if(!bIspress)
{
cell.cell_Progress.hidden=YES;
}
NSString *comicbook_id = [arr_comic_id objectAtIndex:indexPath.row];
NSString *filePath = [NSString stringWithFormat:@"book_%@.pdf",comicbook_id];
NSLog(@"Book Name : %@",filePath);
if(![appDelegate check_Book_available:filePath])
{
NSLog(@"Book Name Not : %@",filePath);
cell.cell_ReadBtn.hidden=YES;
cell.cell_btn.hidden= NO;
}
else
{
cell.cell_btn.hidden=YES;
cell.cell_ReadBtn.hidden=NO;
}
cell.tag=indexPath.row*10+1;
return cell;
}
答案 0 :(得分:1)
-(void) btnDown:(id)sender {
UIButton* cellButton = (UIButton*)sender;
NSIndexPath* selectedIndexPath = [NSIndexPath indexPathForRow:cellButton.tag inSection:0];
UITableViewCell* cell = [self.tableView cellForRowAtIndexPath:selectedIndexPath];
for (id subView in cell.containView) {
if([subView isKindOfClass:[UIProgressView class]) {
UIProgressView * cellProgressView = (UIProgressView*)subView;
cellProgressView.frame = CGRectMake(10,10, 50,50); setYourFrame;
[cellProgressView setHidden:NO];
}
}
}
我希望这个观点能够做到
