How can I achieve something that we can see on login view of Skype app?
It looks like a table View to me with UILabel and UITextField inside it as a subview. I've never done something like so I'd like to know how can I do that.
You can do this. Check the following code
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
UILabel *startDtLbl = [[UILabel alloc] initWithFrame:CGRectMake(10, 10, 80, 25)];
startDtLbl.backgroundColor = [UIColor clearColor];
startDtLbl.tag = 1;
[cell.contentView addSubview:startDtLbl];
UITextField *passwordTF = [[UITextField alloc] initWithFrame:CGRectMake(100, 5, 200, 35)];
passwordTF.tag = 2;
[cell.contentView addSubview:passwordTF];
}
return cell;
}
You can add the fields like the above.

I have a grouped style Tableview which have uilabels in Tableviewcell. Now i want to set height of uilabels equal to height of cell how can i do ths???
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:nil];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
// here i want to make height of label equal to height of cell
UILabel *category = [[UILabel alloc] initWithFrame:CGRectMake(95,1,140,25)];
category.font = [UIFont fontWithName:#"Arial" size:14.0f] ;
category.textAlignment = NSTextAlignmentRight;
[category setBackgroundColor:[UIColor clearColor]];
[cell addSubview:category];
}
In the cellForRowAtIndexPath add; this will return current height set for your tableview:
CGFloat currentCellHeight = [self tableView:tableView heightForRowAtIndexPath:indexPath];
UILabel myLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, customWidth, currentCellHeight)];
Get default cell height
UITableViewCell *cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"Cell"];
UILabel *category = [[UILabel alloc]
initWithFrame:CGRectMake(0,0,cell.frame.size.width,cell.frame.size.width)];
If you want your cell's height, just do the following:
category.frame = CGRectMake(0,0,width,cell.bounds.size.height);
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:nil];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
// Look at this
UILabel *category = [[UILabel alloc]
initWithFrame:CGRectMake(0,0,cell.bounds.size.width,cell.bounds.size.height)];
category.font = [UIFont fontWithName:#"Arial" size:14.0f] ;
category.textAlignment = NSTextAlignmentRight;
[category setBackgroundColor:[UIColor clearColor]];
[cell addSubview:category];
}
use this code...
YOu can use following to find height in
- (float)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
CGSize textSize = [[NSString stringWithFormat:#"%# %#",label.text] sizeWithFont:[UIFont systemFontOfSize:14.0f] constrainedToSize:CGSizeMake(200, 1000.0f) lineBreakMode:NSLineBreakByCharWrapping];
return textSize.height; //height for cell
}
I think there's two things you can do; first try reading this link from apple and review your approach. If you only need a label, why not use the cells textLabel and customize its appearance?
If you really want to use the label approach then consider adding it to the contentView instead of the cell. You can also try to get the bounds of this property, instead of the c
UILabel *category = [[UILabel alloc] initWithFrame:CGRectMake(0,0,width,cell.contentView.bounds.size.height)];
[cell.contentView addSubview:category];
Hope this helps.
// try this code
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(95,1,140,cell.frame.size.height)];
just set the cell bounds to label's frame,like below.
UILabel *myLabel = [[UILabel alloc] initWithFrame:cell.bounds];
I want add label to every row in tableview at right side of the row in iphone programmatically.
Can anyone help me?
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
}
UILabel* lbl = [[UILabel alloc] initWithFrame:CGRectMake(x, y, w, h)];
lbl.font = [UIFont boldSystemFontOfSize:17.0];
lbl.text = [self.arrRows objectAtIndex:indexPath.row];
[cell.contentView addSubview:lbl];
[lbl release];
return cell;
You can achieve it like this :
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
UILabel *lblText = [[UILabel alloc] initWithFrame:CGRectMake(200, 3, 100, 15)]; // For right alignment
lblText.text = [self.arrText objectAtIndex:indexPath.row];
lblText.textColor = [UIColor blackColor];
[cell addSubview:lblText];
[lblText release];
return cell;
}
I think you are asking for code.
try
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UILabel *yourLabel = nil;
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
yourLabel = [[UILabel alloc] initWithFrame:CGRect……];
[yourLabel setTag:9999];
[[cell contentView] addSubview:addressLabel];
}
if (!yourLabel)
yourLabel = (UILabel*)[cell viewWithTag:9999];
return cell;
}
In your cellForRowAtIndexPath: method :-
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier=#"Cell";
UITableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
//set reuseIdentifier:nil for avoid label overlapping
cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:nil];
}
//make your label as according to you
UILabel *label = [[UILabel alloc]initWithFrame:CGRectMake(0.0, 0.0, 320.0, 44.0)];
label.backgroundColor = [UIColor redColor];
// add label content view of cell
[cell.contentView addSubview:label];
return cell;
}
I have a Uibutton in one class and Uitable in different Class...
Now i want to compare IndexPAth(Particular cell Position) with Uibutton Of Different class...
Actually i want to print Different different value on particular cell Which I am Fetching from Different Different Uibutton`s Methods from another class....
Here is My code....
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
//- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
}
if(indexPath == btn1){ // This is the Line What i want , i am trying this but dont go inside the condition..
UILabel *lbl = [[UILabel alloc] initWithFrame:CGRectMake(200, 5, 290, 60)];
lbl.backgroundColor = [UIColor clearColor];
//lbl.editable = NO;
lbl.font = [UIFont fontWithName:#"Helvetica-Bold" size:25];
// txtView1.text= textviewstring;
// txtView1.text = #"Personal";
if([fetchFormArray222 count]<1){
lbl.text=#"";
}
else{
lbl.text = [fetchFormArray222 objectAtIndex:0];
}
// [txtView1 setDelegate:self];
lbl.textColor = [UIColor blackColor];
lbl.textAlignment = UITextAlignmentLeft;
[[cell contentView] addSubview:lbl];
}
else {
}
Check the apple documentation of UITableView.
Have you tried to use the button in the other class to perform a new fetch in the class you're focusing on that loads fetctFormArray222 and then reload the UITableView?
i am displaying array of data in a table view.
my code for that is like this.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
}
// Set up the cell
CGRect labelFrame = CGRectMake(0,0 , 100, 25);
itemNameLabel = [[[UILabel alloc] initWithFrame:labelFrame] autorelease];
itemNameLabel.textAlignment = UITextAlignmentLeft;
itemNameLabel.backgroundColor = [UIColor clearColor];
itemNameLabel.text = [tableData objectAtIndex:indexPath.row];
CGRect anotherLabelFrame = CGRectMake(120, 0, 100, 25);
quantityLabel = [[[UILabel alloc] initWithFrame:anotherLabelFrame] autorelease];
quantityLabel.textAlignment = UITextAlignmentLeft;
quantityLabel.backgroundColor = [UIColor clearColor];
MyGroceryListAppDelegate *appDelegate = (MyGroceryListAppDelegate *)[[UIApplication sharedApplication] delegate];
Category *obj = (Category *)[appDelegate.itemsList objectAtIndex:indexPath.row];
quantityLabel.text = [NSString stringWithFormat:#"%d",obj.quantity];
[cell.contentView addSubview:itemNameLabel];
[cell.contentView addSubview:quantityLabel];
return cell;
}
how can i resolve this.
can any one please help me.
Thank u in advance.
i am giving text for itemNameLabel is using array and for quantityLabel using class object.
so,when i scrolling table view the array names are override on other label,but quantity label is not overriding because it is from class.
i need to display itemNameLabel from array since it changes it value.
when i scroll table view my tableview is looking like this.
Ideally you should alloc all lable in this section
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
}
and in the else part you should just Tag those labels and reuse after it but there is another short and sweet way
if Application is not much resource consuming
change
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
to
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:nil];
Try setting Height for each row using the function
- (CGFloat)tableView:(UITableView *)tv heightForRowAtIndexPath:(NSIndexPath *)indexPath {
return 100.0f;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
}
// Configure the cell.
Book *aBook = [appDelegate.books objectAtIndex:indexPath.row];
UILabel *myLabel1 = [[UILabel alloc] initWithFrame:CGRectMake(0, 10, 300, 22)];
UILabel *myLabel2 = [[UILabel alloc] initWithFrame:CGRectMake(0, 40, 300, 22)];
UILabel *myLabel3 = [[UILabel alloc] initWithFrame:CGRectMake(0, 100, 300, 22)];
myLabel1.text=aBook.title;
myLabel2.text=aBook.description;
myLabel3.text=aBook.pubDate;
[cell addSubview:myLabel1];
[cell addSubview:myLabel2];
[cell addSubview:myLabel3];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
// Set up the cell
return cell;
}
I am having this code. It displays from XML file. When I scroll, the text gets overlapped. Please help me out.
You add labels to your cell each time cell is reused so you end with multiple labels stacked on each other in one cell. What you need to change is to create labels only when cell itself is being created:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
UILabel *myLabel1 = [[UILabel alloc] initWithFrame:CGRectMake(0, 10, 300, 22)];
UILabel *myLabel2 = [[UILabel alloc] initWithFrame:CGRectMake(0, 40, 300, 22)];
UILabel *myLabel3 = [[UILabel alloc] initWithFrame:CGRectMake(0, 100, 300, 22)];
myLabel1.tag = 101;
myLabel2.tag = 102;
myLabel3.tag = 103;
[cell.contentView addSubview:myLabel1];
[cell.contentView addSubview:myLabel2];
[cell.contentView addSubview:myLabel3];
[myLabel1 release];
[myLabel2 release];
[myLabel3 release];
}
// Configure the cell.
Book *aBook = [appDelegate.books objectAtIndex:indexPath.row];
UILabel *myLabel1 = (UILabel*)[cell.contentView viewWithTag:101];
UILabel *myLabel2 = (UILabel*)[cell.contentView viewWithTag:101];
UILabel *myLabel3 = (UILabel*)[cell.contentView viewWithTag:101];
myLabel1.text=aBook.title;
myLabel2.text=aBook.description;
myLabel3.text=aBook.pubDate;
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
// Set up the cell
return cell;
}
Two more things to fix:
Do not forget to release labels you create after adding them to the cell, otherwise you get memory leak and may eventually run into low memory problems (especially with tableview)
add subviews to cell's contentView, not to the cell directly
