iam開發一個應用程序,我使用三個imageviews爲表中的單個行。前兩個圖像加載成功。在加載第三個圖像時,圖像將變成黑色。請告訴我如何處理這個one。下面是imageview聲明的代碼。如何處理imageviews?
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell=[[[UITableViewCell alloc]init] autorelease];
tableview1.separatorStyle=UITableViewCellSeparatorStyleNone;
if(indexPath.row==0)
{
image1=[[[UIImageView alloc]initWithFrame:CGRectMake(12, 8, 90, 90)]autorelease];
image1.frame=CGRectMake(12, 8, 90, 90);
[image1.layer setBorderWidth:1.0f];
[image1.layer setBorderColor:[[UIColor grayColor] CGColor]];
[image1.layer setCornerRadius:1.0f];
image1.layer.masksToBounds = YES;
image1.userInteractionEnabled=YES;
image1.tag=1;
[image1 setContentMode:UIViewContentModeScaleToFill];
if([[odrdata stringForKey:@"keyTo1Image"] isEqualToString:@""])
{
}
else
{
image1.image=[UIImage imageWithContentsOfFile:[odrdata stringForKey:@"keyTo1Image"]];
}
[cell.contentView addSubview:image1];
image2=[[[UIImageView alloc]initWithFrame:CGRectMake(114, 8, 90, 90)]autorelease];
image2.frame=CGRectMake(114, 8, 90, 90);
[image2.layer setBorderWidth:1.0f];
[image2.layer setBorderColor:[[UIColor grayColor] CGColor]];
[image2.layer setCornerRadius:1.0f];
image2.layer.masksToBounds = YES;
image2.userInteractionEnabled=YES;
image2.tag=1;
[image2 setContentMode:UIViewContentModeScaleToFill];
if([[odrdata stringForKey:@"keyTo2Image"] isEqualToString:@""])
{
}
else
{
image2.image=[UIImage imageWithContentsOfFile:[odrdata stringForKey:@"keyTo2Image"]];
}
[cell.contentView addSubview:image2];
image3=[[[UIImageView alloc]initWithFrame:CGRectMake(216, 8, 90, 90)]autorelease];
image3.frame=CGRectMake(216, 8, 90, 90);
[image3.layer setBorderWidth:1.0f];
[image3.layer setBorderColor:[[UIColor grayColor] CGColor]];
[image3.layer setCornerRadius:1.0f];
image3.layer.masksToBounds = YES;
image3.userInteractionEnabled=YES;
image3.tag=3;
[image3 setContentMode:UIViewContentModeScaleToFill];
if([[odrdata stringForKey:@"keyTo3Image"] isEqualToString:@""])
{
}
else
{
image3.image=[UIImage imageWithContentsOfFile:[odrdata stringForKey:@"keyTo3Image"]];
}
[cell.contentView addSubview:image3];
fsttapGesture=[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handlefstTap:)];
fsttapGesture.delegate=self;
[image1 addGestureRecognizer:fsttapGesture];
sndtapGesture=[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handlesndTap:)];
sndtapGesture.delegate=self;
[image2 addGestureRecognizer:sndtapGesture];
trdtapGesture=[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handletrdTap:)];
trdtapGesture.delegate=self;
[image3 addGestureRecognizer:trdtapGesture];
return cell;
}
}
我只在這裏看到一個圖像視圖。你在談論的另外兩個在哪裏? – LucasTizma
像這樣,另外兩個圖像將以水平方式添加到單元格的不同位置。 –
請顯示所有圖片瀏覽的所有相關代碼。否則,幾乎不可能知道發生了什麼問題。 – LucasTizma
