hi friend i now if i use this code it will print multiple value on label but in new line i not want like
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
CGSize labelSize = CGSizeMake(200.0, 20.0);
if ([displayTag length] > 0)
labelSize = [displayTag sizeWithFont: [UIFont boldSystemFontOfSize: 17.0] constrainedToSize: CGSizeMake(labelSize.width, 1000) lineBreakMode: UILineBreakModeWordWrap];
return 24.0 + labelSize.height;
}
return 40.0;
}
this code will print vertical line but i want to print my value on label horizontally how to give multiple value for print on label horizontally on particular cell
for that i was create that but is not working
where i am wrong
this code in my custom cell
TagsLable= [[UILabel alloc]initWithFrame:CGRectMake(360, 15, 150, 21)];
TagsLable.font = [UIFont fontWithName:#"Verdana" size:16.0f];
TagsLable.textAlignment=UITextAlignmentRight;
TagsLable.backgroundColor=[UIColor clearColor];
CGSize fontSize = [tagList sizeWithFont: [UIFont boldSystemFontOfSize: 17.0]];
double finalWidth = fontSize.width * UIBaselineAdjustmentAlignBaselines;
//double finalWidth = fontSize.width + self.numberOfLines;
double finalHeight = self.frame.size.height; //expected height of label
CGSize theStringSize = [tagList sizeWithFont: [UIFont boldSystemFontOfSize: 17.0] constrainedToSize:CGSizeMake(finalWidth, finalHeight) lineBreakMode: UILineBreakModeWordWrap];
int newLinesToPad = (finalWidth - theStringSize.width) / fontSize.width;
for(int i=0; i<newLinesToPad; i++)
{
//tagList = [tagList stringByAppendingString:#","];
tagList=[tagList stringByAppendingFormat:#"%#, ",tag.TagName];
}
What is tag.TagName.
Try this
tagList=[tagList stringByAppendingFormat:#"%#, ",tag.TagName];
NSString *tagList = [tagList stringByAppendingPathComponent:TagName.tag];

I have two UILabels, one above the other.
The top one has fixed size (2 Lines), and the bottom one can expand (0 lines).
The text which I using for the labels can be short and sometimes it can be very long.
How can I calculate the first UILabel max string length without cut a word in the middle?
//Here is the code which create the 2 labels.
titleView = [[UILabel alloc] initWithFrame:CGRectMake(70, 0, 200, 50)];
titleView.numberOfLines = 2;
titleView2 = [[UILabel alloc] initWithFrame:CGRectMake(20, 50, 250, 100)];
titleView2.numberOfLines = 0;
I've solved the problem with this method:
+ (int)getSplitIndexWithString:(NSString *)str frame:(CGRect)frame andFont:(UIFont *)font
{
int length = 1;
int lastSpace = 1;
NSString *cutText = [str substringToIndex:length];
CGSize textSize = [cutText sizeWithFont:font constrainedToSize:CGSizeMake(frame.size.width, frame.size.height + 500)];
while (textSize.height <= frame.size.height)
{
NSRange range = NSMakeRange (length, 1);
if ([[str substringWithRange:range] isEqualToString:#" "])
{
lastSpace = length;
}
length++;
cutText = [str substringToIndex:length];
textSize = [cutText sizeWithFont:font constrainedToSize:CGSizeMake(frame.size.width, frame.size.height + 500)];
}
return lastSpace;
}
CGSize textSize=[someString sizeWithFont:[UIFont systemFontOfSize:12] constrainedToSize:sizeConstraint];
Then you can access the width and height:
float height=textSize.height;
float width=textSize.width;
I want to change the uilabel height as per content and display it in a uitableview cell, there is a custom cell and cell is expand as per uilabel height
When button is pressed then and then cell height is expand as per the uilabel height
Thank you in Advance :-)
//Calculate the size based on the font and linebreak mode of your label
CGSize maxLabelSize = CGSizeMake(300,9999);
CGSize expectedLabelSize = [myString sizeWithFont:myLabel.font
constrainedToSize:maxLabelSize
lineBreakMode:myLabel.lineBreakMode];
//adjust the label the the new height.
CGRect newFrame = myLabel.frame;
newFrame.size.height = expectedLabelSize.height;
myLabel.frame = newFrame;
Try this
[label sizeToFit];
Note that label will increase it's height keeping it's width the same.
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *text = displayText;
//CGSize constraint = CGSizeMake(CELL_CONTENT_WIDTH - (CELL_CONTENT_MARGIN * 2), 20000.0f);
CGSize constraint = CGSizeMake(tableView.frame.size.width - 30, 20000.0f);
CGSize size = [text sizeWithFont:[UIFont systemFontOfSize:15.0f] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];
CGFloat height = MAX(size.height, 44.0f);
return height + 30;
}
Calculate the size of the label text & than set coordinates as
CGSize labelWidth=[_label.text sizeWithFont:[UIFont fontWithName:#"Verdana" size:12] constrainedToSize:CGSizeMake(200, 15) lineBreakMode:UILineBreakModeTailTruncation];
I have a view that is pushed onto the Screen via navigation controllers:
Inside is a UIScrollView.
Then inside the UIScrollView are a few static objects like Images and Labels.
Then comes the hard bit, There is a UITextView with its text loaded from different text files of varying length.
I need to be able to have the UITextView size dynamically to its contents, and the same for the UIScrollView. Is this possible?
float length = [yourText length];
textview.frame = CGRectMake(44, 87, 923, ceilf(length/142)*25);
Here 25 is the constant value assumed as text font width. From this you can set scrollview frame reference to the textview frame.
You can do that with the help of following code. I had done that code for Label and same way you can do that with the help of text-field.
NSString *cellText = "Text Of Your Text-Field";
UIFont *cellFont = [UIFont fontWithName:#"Your Font Name" size:FONT_SIZE];//UIFont *cellFont = [UIFont fontWithName:#"Helvetica-Bold" size:13.0];
CGSize constraintSize = CGSizeMake(#"Width Of Your Text-Field", MAXFLOAT);//CGSize constraintSize = CGSizeMake(220.0f, MAXFLOAT);
CGSize labelSize = [cellText sizeWithFont:cellFont constrainedToSize:constraintSize lineBreakMode:UILineBreakModeWordWrap];
int height = labelSize.height;
frame.origin.x = Starting Position of X;
frame.origin.y = Starting Position of Y;
frame.size.width = Width Of Your TextField;
frame.size.height = height;
UILabel *lblName = [[[UILabel alloc] initWithFrame:frame] autorelease];
lblName.numberOfLines = 0;
lblName.lineBreakMode = UILineBreakModeWordWrap;
lblName.textAlignment = UITextAlignmentLeft;
lblName.textColor = [UIColor whiteColor];
lblName.backgroundColor = [UIColor clearColor];
lblName.font = [UIFont boldSystemFontOfSize:13.0];
And same way you can do For the Scrollview. Just you have to set the Frame of that scrollview and you are done.
Yes you could do something like this:
if ([textView length] > int//any number you want) {
textView.frame = CGRectMake(//just adjust the size an position here);
scrollView.contentSize = CGSizeMake(//adjust scrollView size)
}
else if ([textView length] > int//just another number) {
// you can continue looping that for how often you want
}
For the int in the if statement you check how long the text is. Based on that you adjust the size of both the scrollView and textView.
UILabel inside of a UITableViewCell. On cell tap, height expands and a second UILabel appears with various amounts of data.
The problem is, if the line wraps, sizeWithFont:constrainedToSize:lineBreakMode: does not return the proper height and cuts off the bottom line.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
labelExpanded = [[[UILabel alloc] initWithFrame:CGRectZero] autorelease];
labelExpanded.font = [UIFont boldSystemFontOfSize:11];
labelExpanded.textAlignment = UITextAlignmentLeft;
labelExpanded.lineBreakMode = UILineBreakModeWordWrap;
labelExpanded.numberOfLines = 0;
[cell.contentView addSubview:labelExpanded];
CGSize constraint = CGSizeMake(300, 20000);
CGSize size = [expandedDetails sizeWithFont:[UIFont boldSystemFontOfSize:11] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];
[labelExpanded setText:expandedDetails];
[labelExpanded setFrame:CGRectMake(16, 30, 248, size.height)];
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
if(// Row is Expanded)
{
CGSize constraint = CGSizeMake(300, 20000);
CGSize size = [sameTextAsLabel sizeWithFont:[UIFont boldSystemFontOfSize:11] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];
// I found +8 to height added nice padding
CGFloat height = size.height + 8;
}
else // Row is not expanded
return 30;
}
The same text is fed to both, it consists of a string with multiple new lines \n. If the line is longer than width, word wrap does its job but when calculating its dynamic height, it fails to include the wrapped line.
If I add any value to the [labelExpanded setFrame:height] such as [size.height + 30] my wrapped line shows up. However, if the line isn't wrapped, it adds unnecessary whitespace.
I haven't been able to find a solution online for this.
One thing I note is that you are calculating the size based on a width of 300, but sizing the label at 248.
CGSize constraint = CGSizeMake(300, 20000);
CGSize size = [expandedDetails sizeWithFont:[UIFont boldSystemFontOfSize:11] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];
[labelExpanded setText:expandedDetails];
[labelExpanded setFrame:CGRectMake(16, 30, 248, size.height)];
Why is the label frame width 248 and constraint width is 300?
If a UILabel contains too much text, how can I setup my label so that it shrinks font-sizes?
Here is how I am setting up my UILabel:
descriptionLabel = [[UILabel alloc] initWithFrame:CGRectMake(200, 30, 130, 150)];
[descriptionLabel setFont:[Utils getSystemFontWithSize:14]];
[descriptionLabel setBackgroundColor:[UIColor clearColor]];
[descriptionLabel setTextColor:[UIColor whiteColor]];
descriptionLabel.numberOfLines = 1;
[self addSubview:descriptionLabel];
descriptionLabel.adjustsFontSizeToFitWidth = YES;
descriptionLabel.minimumFontSize = 10.0; //adjust to preference obviously
The following example is tested and verified on iPhone Simulator 3.1.2:
UILabel *descriptionLabel = [[UILabel alloc] initWithFrame:CGRectMake(90, 0, 200, 30)];
descriptionLabel.font = [UIFont systemFontOfSize:14.0];
descriptionLabel.minimumFontSize = 10.0;
descriptionLabel.adjustsFontSizeToFitWidth = YES;
descriptionLabel.numberOfLines = 1;
descriptionLabel.text = #"supercalifragilisticexpialidocious even thought he sound of it is something quite attrocious";
To resize the text in a multi-line UILabel, you can use this helper method (based on code from 11 Pixel Studios):
+ (void)resizeFontForLabel:(UILabel*)aLabel maxSize:(int)maxSize minSize:(int)minSize {
// use font from provided label so we don't lose color, style, etc
UIFont *font = aLabel.font;
// start with maxSize and keep reducing until it doesn't clip
for(int i = maxSize; i >= minSize; i--) {
font = [font fontWithSize:i];
CGSize constraintSize = CGSizeMake(aLabel.frame.size.width, MAXFLOAT);
// This step checks how tall the label would be with the desired font.
CGSize labelSize = [aLabel.text sizeWithFont:font constrainedToSize:constraintSize lineBreakMode:UILineBreakModeWordWrap];
if(labelSize.height <= aLabel.frame.size.height)
break;
}
// Set the UILabel's font to the newly adjusted font.
aLabel.font = font;
}
Set the adjustsFontSizeToFitWidth property to YES.
If you want the number of lines to also increase if needed, use Steve N's solution, with the if statement as so:
if(labelSize.height <= aLabel.frame.size.height)
{
aLabel.numberOfLines = labelSize.height / font.lineHeight;
break;
}
