The page I am working on has a javascript function executed to print parts of the page. For some reason, printing in Safari, causes the window to somehow update. I say somehow, because it does not really refresh as in reload the page, but rather it starts the "rendering" of the page from start, i.e. scroll to top, flash animations start from 0, and so forth. The effect is reproduced by this fiddle: http://jsfiddle.net/fYmnB/ Clicking the print button and finishing or cancelling a print in Safari causes the screen to "go white" for a sec, which in my real website manifests itself as something "like" a reload. While running print button with, let's say, Firefox, just opens and closes the print dialogue without affecting the fiddle page in any way. Is there something with my way of calling the browsers print method that causes this, or how can it be explained - and preferably, avoided? P.S.: On my real site the same occurs with Chrome. In the ex

UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 300, 37)];
label.text = [NSString stringWithFormat:@"something here"];
label.textAlignment = UITextAlignmentCenter;
label.backgroundColor = [UIColor clearColor];
[label autorelease];
return label;
}
or something like this.
You can implement this delegate method, which returns a CGFloat
ReplyDelete- (CGFloat)pickerView:(UIPickerView *)pickerView widthForComponent:(NSInteger)component
This is called on the picker view to determine row width.
No property of picker having set alignment capability.
ReplyDeleteso you need to hard code for this.
see this code
- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)thePickerView {
return 1;
}
- (NSInteger)pickerView:(UIPickerView *)thePickerView numberOfRowsInComponent:(NSInteger)component
{
return 25;
}
- (NSString *)pickerView:(UIPickerView *)thePickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component {
NSString *title=[NSString stringWithFormat:@" %i",row];//here you give extra spaces.
return title;
}
Remember, the view in
ReplyDelete- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view
is actually a UITableViewCell, so you can work with it like:
- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view
{
static NSString *cellIdentifier = @"pickerViewCell";
UITableViewCell *cell = (UITableViewCell*)view;
if(cell==nil)
{
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier] autorelease];
/** customize the cell **/
}
/** set the label **/
cell.textLabel.text = [dataSource objectAtIndex:row];
return cell;
}
