I have a standard UITableView with three sections. At the bottom of the table I'm trying to add a tableFooterView. It seems as though there's a standard spacing between the last row in the table and the top of the tableFooterView, which is fine, but my problem is that there is a different color in this spacing that I can't get rid of. I need that spacing to match the background of my tableView.
Here's some code:
self.menuTable.backgroundColor = [UIColor redColor];
self.menuTable.backgroundView = nil;
self.menuTable.separatorColor = [UIColor clearColor];
self.menuTable.delegate = self;
self.menuTable.sectionHeaderHeight = 10.0;
UIView *footer = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 200)];
footer.backgroundColor = self.menuTable.backgroundColor;
UILabel *footerLabel = [[UILabel alloc] initWithFrame:CGRectMake(60, 0, 205, 100)];
footerLabel.text = #"foo bar.";
footerLabel.textColor = [UIColor blackColor];
footerLabel.backgroundColor = self.menuTable.backgroundColor;
footerLabel.numberOfLines = 10;
footerLabel.font = [UIFont italicSystemFontOfSize:11.0];
[footerLabel sizeToFit];
[footer addSubview:footerLabel];
self.menuTable.tableFooterView = footer;
Here's a screenshot (sorry about the red, but it's the easiest way to see the differences in colors).
Whoops. Earlier I was trying to add a sectionFooterView, and had implemented tableView:heightForFooterInSection:, returning 20 for the last section. That's where that gap was coming from, and it had a default color of white. Since I'm now placing the text as the tableFooterView, I just removed that delegate callback and everything is rendering as expected.
Try this
self.menuTable.backgroundColor = [UIColor clearColor];
self.view.backgroundColor = [UIColor redColor];
UILabel *label = [[UILabel alloc] init];
label.text = #"Hello";
[label sizeToFit];
CGSize size = label.frame.size;
Usually we get the size of the label in this way, but text in the UILabel does not fill all space in it, there's always some margin around the text. That makes drawing label difficult to be exactly the same as visual draft. Anyone could help ？
for example: If you want to put an icon at the bottom of some text, let the margin between them be, for example 50px, and you write icon.frame = CGRectMake(10,textLabel.frame.size.height + textLabel.frame.origin.y + 50, 100, 100); but since the text can't fill all space in UILabel, so the margin in this way should be a bit larger than it should be. So I want to figure out a better way, thanks.
try with this bellow method which returns dynamic height of UILable with its text content... we this method you can set frame of UILable with its text content...
-(float) calculateHeightOfTextFromWidth:(NSString*) text: (UIFont*)withFont: (float)width :(UILineBreakMode)lineBreakMode
{
[text retain];
[withFont retain];
CGSize suggestedSize = [text sizeWithFont:withFont constrainedToSize:CGSizeMake(width, FLT_MAX) lineBreakMode:lineBreakMode];
[text release];
[withFont release];
return suggestedSize.height;
}
and use it like bellow...
UILabel *lblAddress = [[UILabel alloc]init];
[lblAddress setFrame:CGRectMake(110, 31, 200, 50)];
lblAddress.text = #"your Text ";
lblAddress.lineBreakMode = UILineBreakModeWordWrap;
lblAddress.numberOfLines = 0;
lblAddress.font = [UIFont fontWithName:#"Helvetica" size:12];
lblAddress.frame = CGRectMake(lblAddress.frame.origin.x, lblAddress.frame.origin.y,
200,[self calculateHeightOfTextFromWidth:lblAddress.text :lblAddress.font :200 :UILineBreakModeWordWrap] );
lblAddress.textColor = [UIColor darkGrayColor];
[self.view addSubview:lblAddress];

i hope you get some idea from this post...
Friends,
i have created a UILabel with border (just like the image below).
I want to start my label after one/two lines left and then after finishing last line of label again one/two lines below.
Is there any way to get spacing inside label's border?
UILabel *cmntBoxlbl = [[UILabel alloc]initWithFrame:CGRectMake(58, 23, 250, 60)];
cmntBoxlbl.font=[UIFont fontWithName:#"Arial" size:12];
cmntBoxlbl.layer.borderColor = [UIColor darkGrayColor].CGColor;
cmntBoxlbl.layer.borderWidth = 1.0;
NSString *text = [NSString stringWithFormat:#"%#%#%#",#" ",[[self.DtlArray objectAtIndex:indexPath.row] objectForKey:#"comment"],#" "];
cmntBoxlbl.text = text;
cmntBoxlbl.textAlignment = UITextAlignmentCenter;
cmntBoxlbl.lineBreakMode = UILineBreakModeWordWrap;
[cmntBoxlbl setTextColor:[UIColor darkGrayColor]];
CGSize expectedLabelSize = [text sizeWithFont:cmntBoxlbl.font
constrainedToSize:cmntBoxlbl.frame.size
lineBreakMode:UILineBreakModeWordWrap];
CGRect newFrame = cmntBoxlbl.frame;
newFrame.size.height = expectedLabelSize.height;
cmntBoxlbl.frame = newFrame;
cmntBoxlbl.numberOfLines = 0;
[cmntBoxlbl sizeToFit];
[cell addSubview:cmntBoxlbl];
Make current label(commentLabel) color is white. create another label with same content and a little smaller size,place it inside the boarder.Make padding as you wish
Have you tried this-
NSString *text = [NSString stringWithFormat:#"\n\n%#%#%#\n\n",#" ",[[self.DtlArray objectAtIndex:indexPath.row] objectForKey:#"comment"],#" "];
You may create a custom view and
- (void)drawRect:(CGRect)rect {
......;
[string drawInRect:rect withFont:font lineBreakMode:mode alignment:ali];
......;
}
hope that helps
I have a very long string which is something like that below...
[[sqrt(221)-10,-sqrt(221)-10],[11,11]],[[rootof([[474368400,237184200,-125944810200,258530778000],[1,0,-472,884,42215]])/(sqrt(221)*782707860000)+rootof([[409681800,9099248400,-99876110400,-1875803589000],[1,0,-472,884,42215]])/(sqrt(221)*782707860000)*3,rootof([[-3439170900,-50638826700,864180632700,9670592794500],[1,0,-472,884,42215]])/(sqrt(221)*782707860000)+rootof([[1477010700,22974524100,-369910322100,-4442729593500],[1,0,-472,884,42215]])/(sqrt(221)*782707860000)*3],[rootof([[474368400,237184200,-125944810200,258530778000],[1,0,-472,884,42215]])/(sqrt(221)*782707860000)*2+rootof([[409681800,9099248400,-99876110400,-1875803589000],[1,0,-472,884,42215]])/(sqrt(221)*782707860000)*4,rootof([[-3439170900,-50638826700,864180632700,9670592794500],[1,0,-472,884,42215]])/(sqrt(221)*782707860000)*2+rootof([[1477010700,22974524100,-369910322100,-4442729593500],[1,0,-472,884,42215]])/(sqrt(221)*782707860000)*4]],[sqrt(sqrt(221)+15),sqrt(-sqrt(221)+15)]
How can i display the whole thing in a UILabel with more than one lines (0)?
Also, although there are no linebreaks ("\n") in the string, the result is displayed like below....
[[sqrt(221)-10,-sqrt(221)- 10],[11,11]],[[rootof([[474368400,2 37184200,- 125944810200,258530778000],[1, 0,- 472,884,42215]])/(sqrt(221)*78270
Any help?
PS I could upload an image but i am not allowed beacause i am a new user...
textLabel.lineBreakMode = UILineBreakModeWordWrap;
textLabel.numberOfLines = 0;
set the UILabel as a multiline
MyLbl.numberOfLines = xxx;
if you have not enough space for set the UIlabel then also set the textView As an not editable property:
Mytxt = [[UITextView alloc]initWithFrame:CGRectMake(xx.0, x.0, xx.0,xx.0)];
Mytxt.transform = transform;
Mytxt.adjustsFontSizeToFitWidth = YES;
Mytxt.textColor = [UIColor blackColor];
Mytxt.autoresizingMask=UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
[Mytxt setFont:[UIFont fontWithName:#"Arial" size:xx.0]];
Mytxt.backgroundColor = [UIColor clearColor];
Mytxt.delegate = self;
Mytxt.userInteractionEnabled=YES;
Mytxt.editable=NO;
i hope you get the answer.
You can use UITextView with auto size with non editable mode instead of UILabel (or)
CGSize labelSize = yourString sizeWithFont:cellFont
constrainedToSize:CGSizeMake(190.0f, MAXFLOAT); lineBreakMode:UILineBreakModeWordWrap];
This labelsize will dynamically define the label height you can assign to your label
try this code
NSString *yourString = #"[[sqrt(221)-10,-sqrt(221)-10],[11,11]],[[rootof([[474368400,237184200,-125944810200,258530778000],[1,0,-472,884,42215]])/(sqrt(221)*782707860000)+rootof([[409681800,9099248400,-99876110400,-1875803589000],[1,0,-472,884,42215]])";
UILabel *lblNameDesc=[[UILabel alloc] initWithFrame:CGRectMake(55, 10, 250, 21)];
[lblNameDesc setNumberOfLines:0];
lblNameDesc.text=yourString;
[lblNameDesc setBackgroundColor:[UIColor clearColor]];
[lblNameDesc setTextColor:[UIColor colorWithRed:64.0/255.0 green:64.0/255.0 blue:64.0/255.0 alpha:1.0f]];
[self.view addSubview:lblNameDesc];
// [lblNameDesc release];
[lblNameDesc sizeToFit];
supoose your string is. make your fond and width what ever you want:-
NSString longString = #"dsjkghsdkjnfgvsdjgsl,v.........................";
CGSize maximumLabelSize = CGSizeMake(200,MAXFLOAT);
CGSize expectedLabelSize = [longString sizeWithFont:[UIFont fontWithName:#"Aial-BoldMT" size:15.0] constrainedToSize:maximumLabelSize
lineBreakMode:UILineBreakModeWordWrap];
UILabel *myLabel = [[UILabel alloc] initWithFrame:CGRectMake(50, 100, 200, expectedLabelSize.height)];
myLabel.lineBreakMode = UILineBreakModeWordWrap;
myLabel.numberOfLines = 0;
myLabel.text = longString ;
may this will help you
Try This...
textLabel.lineBreakMode = YES;
textLabel.numberOfLines = 10; // or many that you need...
You want UILineBreakModeCharacterWrap if you want your text to be evenly distributed along several lines (so it doesn't try to break at work boundaries).
I'm trying to code the appearance of an UILabel, but I can't get another font applied. The funny (or rather annoying) thing is that if I add a second UILabel, the font WILL BE APPLIED for the second label, BUT NOT the first. I'm slightly going crazy on this... especially the font size won't change if I try to.
My code (found in my ViewDidLoad):
NSString* dateWeekDay = #"MON";
CGRect dateWeekDayFrame = CGRectMake(183, 12, 34, 21);
viewNoteDateWeekDay = [[UILabel alloc] initWithFrame:dateWeekDayFrame];
viewNoteDateWeekDay.text = dateWeekDay;
viewNoteDateWeekDay.textColor = [UIColor blackColor];
viewNoteTitle.font = [UIFont fontWithName:#"Helvetica Neue" size:70.0f]; // I know this size is crazy, but it's just to show that it has no effect whatsoever...
viewNoteDateWeekDay.transform = CGAffineTransformMakeRotation( ( -90 * M_PI ) / 180 );
viewNoteDateWeekDay.backgroundColor = [UIColor clearColor];
NSString* dateDay = #"01";
CGRect dateDayFrame = CGRectMake(209, 3, 47, 50);
viewNoteDateDay = [[UILabel alloc] initWithFrame:dateDayFrame];
viewNoteDateDay.text = dateDay;
viewNoteDateDay.textColor = [UIColor blackColor];
viewNoteDateDay.font = [UIFont fontWithName:#"Helvetica Neue" size:33.0f];
viewNoteDateDay.backgroundColor = [UIColor clearColor];
NSString* dateMonth = #"SEPTEMBER";
CGRect dateMonthFrame = CGRectMake(249, 6, 93, 31);
viewNoteDateMonth = [[UILabel alloc] initWithFrame:dateMonthFrame];
viewNoteDateMonth.text = dateMonth;
viewNoteDateMonth.textColor = [UIColor blackColor];
viewNoteDateMonth.font = [UIFont fontWithName:#"Helvetica Neue" size:12.0f];
viewNoteDateMonth.backgroundColor = [UIColor clearColor];
You are specifying the wrong variable name when you're setting the font property. Your code says: viewNoteTitle.font = ... when it should read viewNoteDateWeekDay.font = ...
