i try to this condition but don't work. If the senderlabel = key#"sender" use the green.png or the grey.png for every rows.
if (senderLabel.text = [tempMsg objectForKey:#"sender"])
{
[cell.msgText setText:[tempMsg objectForKey:#"message"]];
[messTableView setSeparatorStyle:UITableViewCellSeparatorStyleNone];
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
//[cell setFrame:CGRectMake(0,0, size.width, size.height)];
[cell.msgText setFrame:CGRectMake(15,3, size.width, result)];
UIImage* balloon = [[UIImage imageNamed:#"grey.png"] stretchableImageWithLeftCapWidth:24 topCapHeight:15];
UIImageView *newImage = [[UIImageView alloc] initWithFrame:CGRectMake(5, 5, size.width+10, result+10)];
UIView *newView =[[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, cell.frame.size.width, cell.frame.size.height)];
[newImage setImage:balloon];
[newView addSubview:newImage];
[cell setBackgroundView:newView];
}else {
[cell.msgText setText:[tempMsg objectForKey:#"message"]];
[messTableView setSeparatorStyle:UITableViewCellSeparatorStyleNone];
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
//[cell setFrame:CGRectMake(0,0, size.width, size.height)];
[cell.msgText setFrame:CGRectMake(15,3, size.width, result)]; //propriété du texte
UIImage* balloon = [[UIImage imageNamed:#"green.png"] stretchableImageWithLeftCapWidth:24 topCapHeight:15];
UIImageView *newImage = [[UIImageView alloc] initWithFrame:CGRectMake(5, 5, size.width+10, result+10)];
UIView *newView =[[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, cell.frame.size.width, cell.frame.size.height)];
[newImage setImage:balloon];
[newView addSubview:newImage];
[cell setBackgroundView:newView];
}
return cell;
}
if (senderLabel.text = [tempMsg objectForKey:#"sender"]) is not correct. You need to use isEqual in your comparison.
if ([senderLabel.text isEqual:[tempMsg objectForKey:#"sender"]])
First of all, here
if (senderLabel.text = [tempMsg objectForKey:#"sender"])
you are making an assignment, not a comparison, comparing would be
if (senderLabel.text == [tempMsg objectForKey:#"sender"])
However, that would compare if it's the exact same object in memory, which is probably not what you want, if you want to check if the string has the same text, you have to use
[string isEqualToString:anotherString]
To get indexpath you can use like this:
NSIndexPath *indexpath = [NSIndexPath indexPathForRow:0 inSection:0];
and for comparison:
if ([string compare:anotherString] == NSOrderedSame)

I want to add an UIActivityIndicator to an UITableViewCell. How can I do?
try like this
UITableViewCell *cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:#"NoReuse"] autorelease];
cell.textLabel.text = #"Loading...";
UIActivityIndicatorView *spinner = [[[UIActivityIndicatorView alloc]
initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray] autorelease];
// Spacer is a 1x1 transparent png
UIImage *spacer = [UIImage imageNamed:#"spacer"];
UIGraphicsBeginImageContext(spinner.frame.size);
[spacer drawInRect:CGRectMake(0,0,spinner.frame.size.width,spinner.frame.size.height)];
UIImage* resizedSpacer = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
cell.imageView.image = resizedSpacer;
[cell.imageView addSubview:spinner];
[spinner startAnimating];
return cell;
UIActivityIndicatorView *spinner = [[[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite] autorelease];
spinner.frame = CGRectMake(205.0f, 0.0f, 44.0f, 44.0f);
spinner.tag = 3;
[cell.contentView addSubview:spinner];
I am currently creating my own custom section headers but I have never dont any text editing via code.. and my new method that I am using to populate my custom header is doing some weird things as shown below
I would like to change the text to white and be slightly bolder and also make the white background transparent..
this is the code I am using to do this
- (UIView *) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
UIView *headerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.bounds.size.width, 30)];
[headerView setBackgroundColor:[UIColor grayColor]];
// Add the label
UILabel *headerLabel = [[UILabel alloc] initWithFrame:CGRectMake(0.0, 0.5, 20, 20)];
// do whatever headerLabel configuration you want here
headerLabel.text = [self tableView:tableView titleForHeaderInSection:section];
[headerView addSubview:headerLabel];
// Return the headerView
return headerView;
}
I have tried this
[headerLabel.backgroundColor:[UIColor clearColor]];
etc but its not working :(
I would like to change the text to white...
UILabel's textColor property is your friend here.
And slightly bolder...
No problem! headerLabel.font = [UIFont boldSystemFontOfSize:mySize];
And make a white transparent background.
Whoa, whoa, that is the worst setter syntax ive ever seen!!! My lord, myLabel.backgroundColor is a getter, change:
[headerLabel.backgroundColor:[UIColor clearColor]];
to:
[headerLabel setBackgroundColor:[UIColor clearColor]];
Lucky for you, using your syntax would have just sent a message to nil, which is defaulting the background color of your label to white.
Use following code...
-(UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
UILabel *headername = [[UILabel alloc]initWithFrame:CGRectMake(20, 5, 270, 34)];
headername.backgroundColor = [UIColor clearColor];
headername.textColor = [UIColor blackColor];
if(section == 0)
{
headername.text = #"Name that u wish";
}
else
{
headername.text = #"Name that u wish";
}
UIView *headerView = [[UIView alloc] init];
UIImageView *tempimage = [[UIImageView alloc]initWithFrame:CGRectMake(10, 5, 300,34)];
tempimage.image = [UIImage imageNamed:#"whitebackground.png"];
[headerView addSubview:tempimage];
[headerView addSubview:headername];
return headerView;
}
Hope, this will help you...chill
all i have done to get the customized header in table is as following and it is working fine for me
UIView *containerView =
[[[UIView alloc]
initWithFrame:CGRectMake(0, 0, 300, 60)]
autorelease];
UILabel *headerLabel =
[[[UILabel alloc]
initWithFrame:CGRectMake(10, 20, 300, 40)]
autorelease];
headerLabel.text = NSLocalizedString(#"Header for the table", #"");
headerLabel.textColor = [UIColor whiteColor];
headerLabel.shadowColor = [UIColor blackColor];
headerLabel.shadowOffset = CGSizeMake(0, 1);
headerLabel.font = [UIFont boldSystemFontOfSize:22];
headerLabel.backgroundColor = [UIColor clearColor];
[containerView addSubview:headerLabel];
self.tableView.tableHeaderView = containerView;
i just put it in viewDidLoad: method
I have Created custom cell.And i have table view with Grouped style.Now i want to put Backgroung image to each cell of different section.How to set the background image of custom cell.
Here is the code for creating the custom cell.
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 305, 90)];
// view.backgroundColor=[UIColor darkGrayColor];
UIImageView *imageV = [[UIImageView alloc] initWithFrame:CGRectMake(11, 9, 61, 55)];
// NSLog(#"imageArray%#",[play.imageArray count]);
NSString *img=[play.imageArray objectAtIndex:indexPath.row];
NSLog(#"img=%#",img);
imageV.image = [UIImage imageNamed:img];
[view addSubview:imageV];
[imageV release];
UILabel *lblAchievementName = [[UILabel alloc] initWithFrame:CGRectMake(90, 10, 168, 21)];
lblAchievementName.text = [play.listData objectAtIndex:indexPath.row];
lblAchievementName.backgroundColor=[UIColor clearColor];
lblAchievementName.textColor=[UIColor orangeColor];
[lblAchievementName setFont:[UIFont fontWithName:#"Arial Black" size:16.5]];
[view addSubview:lblAchievementName];
[lblAchievementName release]
[cell.contentView addSubview:view];
return cell;
Now how to set the backgroung image for this custom view?
You can try this code that will help you.
Put this code in cellForRowAtIndexPath method
UIImageView *av = [[UIImageView alloc] initWithFrame:CGRectMake(20, 20, 277, 58)];
av.backgroundColor = [UIColor clearColor];
av.opaque = NO;
av.image = [UIImage imageNamed:#"categorytab1.png"];
cell.backgroundView = av;
set thru setBackgroundView method.Form the ImageView with ur need Image aand set that as,
[cell setBackgroundView:urBgImgView];
You can use following code for different image in different section.
UIImageView *imageV = [[UIImageView alloc] initWithFrame:CGRectMake(11, 9, 61, 55)];
// NSLog(#"imageArray%#",[play.imageArray count]);
NSString *img=[play.imageArray objectAtIndex:indexPath.row];
NSLog(#"img=%#",img);
if (indexPath.section == 0) {
imageV.image = [UIImage imageNamed:img0];
}
else if (indexPath.section == 1) {
imageV.image = [UIImage imageNamed:img1];
}
else if (indexPath.section == 2) {
imageV.image = [UIImage imageNamed:img2];
}
[view addSubview:imageV];
[imageV release];
i'd rather to add a CALayer or UIImageView to be the backgroud view. Because i used to set the BackgroundColor, but it never workd for me. so i changed my mind by this way.
I have 2 images which I want to join side by side and show in accessory view.
CGSize itemSize = CGSizeMake(40, 40);
UIGraphicsBeginImageContext(itemSize);
CGRect imageRect = CGRectMake(20.0, 20.0, 20, 20);
[[UIImage imageNamed:#"homesmall.png"] drawInRect:imageRect];
CGRect imageRect1 = CGRectMake(0.0, 0.0, 20, 20);
[[UIImage imageNamed:#"update.png"] drawInRect:imageRect1];
UIImageView *statusImageView = (UIImageView *) cell.accessoryView;
statusImageView.image= UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
I am trying to put both the images side by side but somehow nothing in coming in accessory view.
[cell accessoryView] is UIView, not UIImageView. And I don't get why do you draw your images since you have them in the bundle.
Why not:
UIImageView * image1 = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"homesmall.png"]];
UIImageView * image2 = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"update.png"]];
[image1 setFrame:CGRectMake(0,0,20,20)];
[image2 setFrame:CGRectMake(20,0,20,20)];
UIView * cellAcc = [[UIView alloc] initWithFrame:CGRectMake(0,0,40,40)];
[cellAcc addSubview:image1];
[cellAcc addSubview:image2];
[cell setAccessoryView:cellAcc];
[image1 release];
[image2 release];
[cellAcc release];
I need so set the name of the UIViewController and an image to the navigationBar. So far I am able to display the image, but the title is of course missing.
// show image
UIImage *image = [UIImage imageNamed: #"bar_icon.png"];
UIImageView *imageView = [[UIImageView alloc] initWithImage: image];
imageView.frame = CGRectMake(0, 0, 40, 40);
self.navigationItem.titleView = imageView;
[imageView release];
Thanks for your help,
BR, doonot
// show image
UIImage *image = [UIImage imageNamed: #"bar_icon.png"];
UIImageView *imageView = [[UIImageView alloc] initWithImage: image];
imageView.frame = CGRectMake(70, 0, 40, 40);
// label
UILabel *tmpTitleLabel = [[UILabel alloc] initWithFrame:CGRectMake(120, 0, 100, 40)];
tmpTitleLabel.text = #"Mannschaft";
tmpTitleLabel.backgroundColor = [UIColor clearColor];
tmpTitleLabel.textColor = [UIColor whiteColor];
CGRect applicationFrame = CGRectMake(0, 0, 300, 40);
UIView * newView = [[[UIView alloc] initWithFrame:applicationFrame] autorelease];
[newView addSubview:imageView];
[newView addSubview:tmpTitleLabel];
self.navigationItem.titleView = newView;
[imageView release];
[tmpTitleLabel release];
Create a UIView with 2 subview: a UIImageView and a UILabel. Set the titleView to the UIView.
