用图像填充自定义tableviewCell
我正试图做到这一点 。 目前我有这个 。
所以我到目前为止将图像放在我的customTableViewCell中。 但它总是在每一行放置相同的图像。 我想要的是在下一行拿下一张图片。
我有一个计数器，即“indexOfIndexPath”。 这就是我在我的CellForRowAtIndexPath中所做的。
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *simpleTableIdentifier = @"PlayerCustomCell"; PlayerCustomCell *cell = (PlayerCustomCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier]; if (cell == nil) { NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"PlayerCustomCell" owner:self options:nil]; cell = [nib objectAtIndex:0]; } if(indexPath.row == 0){ NSIndexPath *path = [NSIndexPath indexPathForRow:indexPath.row+_indexOfIndexPath inSection:0]; NSLog(@"%@",path); Team *team = [self.fetchedResultsController objectAtIndexPath:path]; if(!img1){ img1 = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:team.image]]; UIImage* image = [[UIImage alloc] initWithData:img1]; [cell setImage:image forPosition:1]; _indexOfIndexPath++; } NSIndexPath *path1 = [NSIndexPath indexPathForRow:indexPath.row+_indexOfIndexPath inSection:0]; NSLog(@"%@",path1); Team *team1 = [self.fetchedResultsController objectAtIndexPath:path1]; if(!img2){ img2 = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:team1.image]]; UIImage* image = [[UIImage alloc] initWithData:img2]; [cell setImage:image forPosition:2]; _indexOfIndexPath++; } NSIndexPath *path2 = [NSIndexPath indexPathForRow:indexPath.row+_indexOfIndexPath inSection:0]; NSLog(@"%@",path2); Team *team2 = [self.fetchedResultsController objectAtIndexPath:path2]; if(!img3){ img3 = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:team2.image]]; UIImage* image = [[UIImage alloc] initWithData:img3]; [cell setImage:image forPosition:3]; _indexOfIndexPath++; } NSIndexPath *path3 = [NSIndexPath indexPathForRow:indexPath.row+_indexOfIndexPath inSection:0]; Team *team3 = [self.fetchedResultsController objectAtIndexPath:path3]; if(!img4){ img4 = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:team3.image]]; UIImage* image = [[UIImage alloc] initWithData:img4]; [cell setImage:image forPosition:4]; _indexOfIndexPath++; }else{ img4 = [[NSData alloc] initWithContentsOfFile:@"keeperNil.jpg"]; UIImage* image = [[UIImage alloc] initWithData:img4]; [cell setImage:image forPosition:4]; } NSIndexPath *path4 = [NSIndexPath indexPathForRow:indexPath.row+_indexOfIndexPath inSection:0]; Team *team4 = [self.fetchedResultsController objectAtIndexPath:path4]; if(!img5){ img5 = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:team4.image]]; UIImage* image = [[UIImage alloc] initWithData:img5]; [cell setImage:image forPosition:5]; _indexOfIndexPath++; } NSIndexPath *path5 = [NSIndexPath indexPathForRow:indexPath.row+_indexOfIndexPath inSection:0]; Team *team5 = [self.fetchedResultsController objectAtIndexPath:path5]; if(!img6){ img6 = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:team5.image]]; UIImage* image = [[UIImage alloc] initWithData:img6]; [cell setImage:image forPosition:6]; _indexOfIndexPath++; } }else{ if(img1){ UIImage* image = [[UIImage alloc] initWithData:img1]; if(image == nil){ image = [image initWithContentsOfFile:@"keeperNil.jpg"]; }else{ [cell setImage:image forPosition:1]; } } if(img2){ UIImage* image = [[UIImage alloc] initWithData:img2]; if(image == nil){ image = [image initWithContentsOfFile:@"keeperNil.jpg"]; }else{ [cell setImage:image forPosition:2]; } } if(img3){ UIImage* image = [[UIImage alloc] initWithData:img3]; if(image == nil){ image = [image initWithContentsOfFile:@"keeperNil.jpg"]; }else{ [cell setImage:image forPosition:3]; } } if(img4){ UIImage* image = [[UIImage alloc] initWithData:img4]; if(image == nil){ image = [image initWithContentsOfFile:@"keeperNil.jpg"]; }else{ [cell setImage:image forPosition:4]; } } if(img5){ UIImage* image = [[UIImage alloc] initWithData:img5]; if(image == nil){ image = [image initWithContentsOfFile:@"keeperNil.jpg"]; }else{ [cell setImage:image forPosition:5]; } } if(img6){ UIImage* image = [[UIImage alloc] initWithData:img6]; if(image == nil){ image = [image initWithContentsOfFile:@"keeperNil.jpg"]; }else{ [cell setImage:image forPosition:6]; } } } return cell; 有人有一个想法如何解决这个问题？
提前致谢？
如果我理解正确，你想要的
- 表格0中的图像0,1,2,3,4,5，
- 表格行1中的图像6,7,8,9,10,11，
- … 等等。
这应该与以下代码一起工作：
#define IMAGES_PER_ROW 6 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *simpleTableIdentifier = @"PlayerCustomCell"; PlayerCustomCell *cell = (PlayerCustomCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier]; if (cell == nil) { NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"PlayerCustomCell" owner:self options:nil]; cell = [nib objectAtIndex:0]; } NSInteger frcRow = indexPath.row * IMAGES_PER_ROW; // row in fetched results controller for (int col = 1; col <= IMAGES_PER_ROW; col++) { NSIndexPath *path = [NSIndexPath indexPathForRow:frcRow inSection:0]; Team *team = [self.fetchedResultsController objectAtIndexPath:path]; NSData *imgData = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:team.image]]; UIImage *image; if (imgData == nil) { // default image image = [UIImage imageWithContentsOfFile:@"keeperNil.jpg"]; } else { image = [UIImage imageWithData:imgData]; } [cell setImage:image forPosition:col]; frcRow ++; } return cell; }
请注意，表视图行的数量与获取的结果控制器中的行数不同，这必须在numberOfRowsInSection考虑：
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { id <NSFetchedResultsSectionInfo> sectionInfo = [[fetchedResultsController sections] objectAtIndex:section]; NSInteger count = [sectionInfo numberOfObjects]; return (count + IMAGES_PER_ROW - 1)/IMAGES_PER_ROW; }
你为什么不把你的图像放在这样的条件下，
if(indexPath.row == 0) { Your first image.... } if(indexPath.row == 1) { Your second image.... }
