I have this code that returns a CATextLayer to place over a video and it is returning blurry text. I have searched online and most people recommended adding textLayer.contentsScale but this did not work for me.
- (CATextLayer *)buildTextLayerWithText:(NSString *)text atPosition:(WatermarkPosition)position forVideoSize:(CGSize)videoSize
{
CATextLayer *textLayer = [[CATextLayer alloc] init];
NSMutableDictionary *attributes = [[NSMutableDictionary alloc] init];
CGFloat fontSize = videoSize.height / 20.0;
[attributes setObject:(__bridge id)(__bridge CFTypeRef)([ChannelsInterface mediumFontOfSize:fontSize]) forKey:(NSString*)kCTFontAttributeName];
[attributes setObject:(__bridge id)[[UIColor whiteColor] CGColor] forKey:(NSString*)kCTForegroundColorAttributeName];
[attributes setObject:[NSNumber numberWithFloat:fontSize] forKey:(NSString*)kCTFontSizeAttribute];;
NSAttributedString *attributedString = [[NSAttributedString alloc] initWithString:text attributes:attributes];
textLayer.string = attributedString;
CGSize textLayerSize = [text sizeWithAttributes:attributes];
textLayer.contentsScale = [UIScreen mainScreen].scale;
[textLayer setFrame:getFrameForPosition(textLayerSize, videoSize, position)];
textLayer.shadowColor = [UIColor blackColor].CGColor;
textLayer.shadowRadius = 1.0f;
textLayer.shadowOpacity = 0.5f;
textLayer.shadowOffset = CGSizeMake(0.0f, 0.0f);
[textLayer setRasterizationScale:[UIScreen mainScreen].scale];
[textLayer setShouldRasterize:YES];
return textLayer;
}

I don't know how to fix it to make text to Center.
//Edit
I add your device but in vain
NSMutableParagraphStyle *styleCenter = [[NSParagraphStyle defaultParagraphStyle] mutableCopy];
styleCenter.alignment = kCTCenterTextAlignment;
NSDictionary *attributes = #{NSFontAttributeName:txtFont,NSForegroundColorAttributeName:txtColor,NSParagraphStyleAttributeName:styleCenter};
[txt drawInRect:CGRectMake(0, 0, targetSize.width, targetSize.height) withAttributes:attributes];
the text show at right not center, so weird
Try this:
UIGraphicsBeginImageContext(targetSize);
NSString *txt = #"my String";
UIColor *txtColor = [UIColor whiteColor];
UIFont *txtFont = [UIFont systemFontOfSize:30];
NSDictionary *attributes = #{NSFontAttributeName:txtFont, NSForegroundColorAttributeName:txtColor};
CGRect txtRect = [txt boundingRectWithSize:CGSizeZero
options:NSStringDrawingUsesLineFragmentOrigin
attributes:attributes
context:nil];
[txt drawAtPoint:CGPointMake(targetSize.width/2 - txtRect.size.width/2, targetSize.height/2 - txtRect.size.height/2) withAttributes:attributes];
UIImage *resultImg = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
NSMutableParagraphStyle *styleCenter = [[NSParagraphStyle defaultParagraphStyle] mutableCopy];
styleCenter.alignment = NSCenterTextAlignment;
NSDictionary *attributes = #{NSFontAttributeName:txtFont,NSForegroundColorAttributeName:txtColor,NSParagraphStyleAttributeName:styleCenter};
[txt drawInRect:rect withAttributes:attributes];
This category on NSString will draw the centered text in rect with given below font:
#implementation NSString (Helpers)
- (void)drawCentredInRect:(CGRect)rect withFont:(nullable UIFont *)font andForegroundColor:(nullable UIColor *)foregroundColor {
NSMutableDictionary *attributes = [NSMutableDictionary new];
if (font) {
attributes[NSFontAttributeName] = font;
}
if (foregroundColor) {
attributes[NSForegroundColorAttributeName] = foregroundColor;
}
CGSize textSize = [self sizeWithAttributes:attributes];
CGPoint drawPoint = CGPointMake(
CGRectGetMidX(rect) - (int) (textSize.width / 2),
CGRectGetMidY(rect) - (int) (textSize.height / 2)
);
[self drawAtPoint:drawPoint withAttributes:attributes];
}
I tried the answer for your clever question,Now I got the solution
+(UIImage*) drawText:(NSString*)text inImage:(UIImage*)image atPoint:(CGPoint)point
{
UIGraphicsBeginImageContextWithOptions(image.size, YES, 0.0f);
[image drawInRect:CGRectMake(0,0,image.size.width,image.size.height)];
CGRect rect = CGRectMake(point.x, point.y, image.size.width, image.size.height);
[[UIColor whiteColor] set];
if([text respondsToSelector:#selector(drawInRect:withAttributes:)])
{
//iOS 7 or above iOS 7
NSMutableParagraphStyle *style = [[NSParagraphStyle defaultParagraphStyle] mutableCopy];
style.alignment = NSTextAlignmentCenter;
NSDictionary *attr = [NSDictionary dictionaryWithObject:style forKey:NSParagraphStyleAttributeName];
[text drawInRect:rect withAttributes:attr];
}
UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return newImage;
}
Please call the above method in where you pick the image like below
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
UIImage *imagePicked = info[UIImagePickerControllerEditedImage];
picker.delegate = self;
self.imageViewTextCenter.image = [ViewController drawText:#"WELCOME"
inImage:imagePicked
atPoint:CGPointMake(0, 0)];;
[picker dismissViewControllerAnimated:YES completion:nil];
}
EDIT: I figured out that i needed to remove subviews, once the view did disappear
[[self.scrollView subviews]makeObjectsPerformSelector:#selector(removeFromSuperview)];
My problem is that I have an UILabel which updates the text correctly, but won't remove the old text. I think maybe it's because there are 2 UILabels on top of each other, here is a picture of it:
And here is my code. I can't see where the duplicate is:
for (int i = 0; i < array1.count; i++) {
NSNumber *myNumber = [myscoretext objectAtIndex:i];
float myScore = myNumber.floatValue;
NSNumber *levelNumber = [neededscoretext objectAtIndex:i];
float levelScore = levelNumber.floatValue;
for (int i = 0; i < array1.count; i++) {
NSNumber *myNumber = [myscoretext objectAtIndex:i];
float myScore = myNumber.floatValue;
NSNumber *levelNumber = [neededscoretext objectAtIndex:i];
float levelScore = levelNumber.floatValue;
float progressScore = ((float)myScore/(float)levelScore);
CGRect frame;
frame.origin.x = self.scrollView.frame.size.width * i;
frame.origin.y = 0;
frame.size = self.scrollView.frame.size;
UIView *subview = [[UIView alloc] initWithFrame:frame];
subview.backgroundColor = [UIColor clearColor];
NSArray *colorArray = [NSArray arrayWithObjects:edmeral, turqouise, orange, red, nil];
// Labeled progress views
self.labeledProgressView = [[DALabeledCircularProgressView alloc]
initWithFrame:CGRectMake(25.0f, 20.0f, 100.0f, 100.0f)];
self.labeledProgressView.roundedCorners = NO;
self.labeledProgressView.trackTintColor = [UIColor colorWithWhite:1.0f alpha:0.8];
imageLevel = [[UIImageView alloc] initWithFrame:CGRectMake(25.0f, 20.0f, 100.0f, 100.0f)];
imageLevel.backgroundColor = [UIColor clearColor];
self.Scoreint = [[UILabel alloc] initWithFrame:CGRectMake(-25.0f, 130, 195, 21)];
self.Scoreint.backgroundColor = [UIColor clearColor];
self.Scoreint.textColor = [UIColor blackColor];
[self.Scoreint setFont:[UIFont fontWithName:#"HelveticaNeue-Thin" size:15]];
self.Scoreint.textAlignment = NSTextAlignmentCenter;
self.Scoreint.text = #"";
if (myScore == 0) {
NSString *scoreString = [NSString stringWithFormat:#"0 / %5ld", (long)levelScore];
[self.Scoreint setText:scoreString];
}
else {
NSString *scoreString = [NSString stringWithFormat:#"%5li / %5li", (long)myScore, (long)levelScore];
[self.Scoreint setText:scoreString];
}
[subview addSubview:Scoreint];
I hope some of you guys can help me out with this! :)
the other way, you should do it, it's remove the label from superView everytime, before you initialize it.
You modify the code like this,
if(self.Scoreint) {
[self.Scoreint removeFromSuperview];
}
self.Scoreint = [[UILabel alloc] initWithFrame:CGRectMake(-25.0f, 130, 195, 21)];
self.Scoreint.backgroundColor = [UIColor clearColor];
self.Scoreint.textColor = [UIColor blackColor];
[self.Scoreint setFont:[UIFont fontWithName:#"HelveticaNeue-Thin" size:15]];
self.Scoreint.textAlignment = NSTextAlignmentCenter;
self.Scoreint.text = #"";
that happens because you instantiate the UILabel each time, You have to instantiate the it only once, outside the for loop, and then just change the title.
This might work, i haven't tried it
self.Scoreint = [[UILabel alloc] initWithFrame:CGRectMake(-25.0f, 130, 195, 21)];
self.Scoreint.backgroundColor = [UIColor clearColor];
self.Scoreint.textColor = [UIColor blackColor];
[self.Scoreint setFont:[UIFont fontWithName:#"HelveticaNeue-Thin" size:15]];
self.Scoreint.textAlignment = NSTextAlignmentCenter;
self.Scoreint.text = #"";
for (int i = 0; i < array1.count; i++) {
NSNumber *myNumber = [myscoretext objectAtIndex:i];
float myScore = myNumber.floatValue;
NSNumber *levelNumber = [neededscoretext objectAtIndex:i];
float levelScore = levelNumber.floatValue;
for (int i = 0; i < array1.count; i++) {
NSNumber *myNumber = [myscoretext objectAtIndex:i];
float myScore = myNumber.floatValue;
NSNumber *levelNumber = [neededscoretext objectAtIndex:i];
float levelScore = levelNumber.floatValue;
float progressScore = ((float)myScore/(float)levelScore);
CGRect frame;
frame.origin.x = self.scrollView.frame.size.width * i;
frame.origin.y = 0;
frame.size = self.scrollView.frame.size;
UIView *subview = [[UIView alloc] initWithFrame:frame];
subview.backgroundColor = [UIColor clearColor];
NSArray *colorArray = [NSArray arrayWithObjects:edmeral, turqouise, orange, red, nil];
// Labeled progress views
self.labeledProgressView = [[DALabeledCircularProgressView alloc]
initWithFrame:CGRectMake(25.0f, 20.0f, 100.0f, 100.0f)];
self.labeledProgressView.roundedCorners = NO;
self.labeledProgressView.trackTintColor = [UIColor colorWithWhite:1.0f alpha:0.8];
imageLevel = [[UIImageView alloc] initWithFrame:CGRectMake(25.0f, 20.0f, 100.0f, 100.0f)];
imageLevel.backgroundColor = [UIColor clearColor];
[self.Scoreint setFont:[UIFont fontWithName:#"HelveticaNeue-Thin" size:15]];
self.Scoreint.textAlignment = NSTextAlignmentCenter;
self.Scoreint.text = #"";
if (myScore == 0) {
NSString *scoreString = [NSString stringWithFormat:#"0 / %5ld", (long)levelScore];
[self.Scoreint setText:scoreString];
}
else {
NSString *scoreString = [NSString stringWithFormat:#"%5li / %5li", (long)myScore, (long)levelScore];
[self.Scoreint setText:scoreString];
}
[subview addSubview:Scoreint];
In similar situation, the property of UIView’s visual appearance helped me. Try this:
self.Scoreint.clearsContextBeforeDrawing = true
I just want to know number of lines, given the font, constraints, and the text. Can I figure it out without creating a UILabel?
+ (int)numberOfLines:(NSDictionary *)data{
NSString *myString = [some string calculation];
CGSize sizeConstrain = CGSizeMake(some constrain calculation);
CGSize stringSize = [myString sizeWithFont:someFont constrainedToSize:sizeConstrain];
CGRect labelFrame = CGRectMake(0,
0,
stringSize.width,
stringSize.height + 2);
UILabel *label = [[UILabel alloc]initWithFrame:labelFrame];
label.text = myString;
return label.numberOfLines;
}
Yes
+ (int)numberOfLines:(NSDictionary *)data{
NSString *myString = [some string calculation];
CGSize sizeConstrain = CGSizeMake(some constrain calculation);
CGSize stringSize = [myString sizeWithFont:someFont constrainedToSize:sizeConstrain];
return (stringSize.height/someFont.lineHeight);
}
EDIT: I used this for UITextView and iOS7
- (CGFloat) getRowsForText:(NSString*) text{
CGFloat fixedWidth = 300;
UIFont *font = [UIFont fontWithName:#"HelveticaNeue" size:14];
NSMutableParagraphStyle *paragrapStyle = [[NSMutableParagraphStyle alloc] init];
paragrapStyle.alignment = NSTextAlignmentLeft;
textStepAttr = [NSDictionary dictionaryWithObjectsAndKeys:
font,NSFontAttributeName,
paragrapStyle, NSParagraphStyleAttributeName,
nil];
NSAttributedString *attributedText = [[NSAttributedString alloc] initWithString:text attributes:textStepAttr];
CGRect rect = [attributedText boundingRectWithSize:CGSizeMake(fixedWidth, MAXFLOAT)
options:NSStringDrawingUsesLineFragmentOrigin
context:nil];
return (rect.size.height / font.lineHeight) ;
}
I am creating an iOS app that needs to run on all device. When creating a slideshow I did not want to have an image for each device. I creating a method to generate the images. It takes a background image, main sink image, and 2 UILabels and scales accordingly. For portrait orientation on all the devices it works perfectly. On the iPad I also need landscape. When I rotate it something goes wrong because it just stretches the images. I am not sure what is happening to my view bounds.
Sorry my code is so long.

The frame of your view hasn't been correctly set in viewDidLoad method, yet. It would be more accurate to move frame-size related code to viewWillAppear: method. Dimensions of the frame will be correct in viewWillAppear: or viewDidAppear: methods. Then, you may want to keep a boolean variable in order to generate images at the first appearance only.
I have a multiple lines UILabel with attributed text.
All the lines in the text are of the same font, but each line is of a different font size.
I'm trying to achieve the exact same vertical space between each line.
However what is being displayed has variable spaces. It is as if something is adding a vertical margin to the font based on the font size.
CGFloat y = 0;
NSMutableAttributedString *attString=[[NSMutableAttributedString alloc] initWithString:#""];
NSArray *linesArray = [NSArray arrayWithObjects:#"One I\n",
#"Two I\n",
#"Three I\n",
#"Four I\n",
#"Five I\n", nil];
CGFloat fontSize = 10.0;
for(NSString *line in linesArray) {
NSMutableAttributedString *attributedLine = [[NSMutableAttributedString alloc] initWithString:line];
NSInteger stringLength=[line length];
[attributedLine addAttribute:NSFontAttributeName
value:[UIFont fontWithName:#"TimesNewRomanPSMT" size:fontSize]
range:NSMakeRange(0, stringLength)];
NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
paragraphStyle.lineSpacing = 0.0f;
paragraphStyle.alignment = NSTextAlignmentRight;
[attributedLine addAttributes:#{ NSParagraphStyleAttributeName : paragraphStyle} range:NSMakeRange(0, stringLength)];
[attString appendAttributedString:attributedLine];
fontSize += 10.0;
}
UILabel *label = [[UILabel alloc] initWithFrame:CGRectZero];
label.backgroundColor = [UIColor clearColor];
label.textColor = [UIColor blackColor];
label.numberOfLines = 0;
label.attributedText = attString;
[label sizeToFit];
CGRect newFrame = label.frame;
newFrame.size.width = self.view.frame.size.width - 40;
newFrame.origin.y = y;
newFrame.origin.x = 0;
label.frame = newFrame;
[self.view addSubview:label];
Any suggestions on the code I should use in order for it to display no space at all between each line of text?
I have been doing something similar, so maybe you could try something like this (typed in browser, watch out!):
NSMutableParagraphStyle *style = [[NSMutableParagraphStyle alloc] init];
[style setAlignment: NSTextAlignmentRight];
[style setLineSpacing:0];
for(NSString *line in linesArray) {
NSMutableParagraphStyle *subStyle = [style mutableCopy];
[subStyle setMaximumLineHeight:10]; // play around with this value <-----
NSDictionary *attributes =
#{
NSFontAttributeName : [UIFont fontWithName:#"TimesNewRomanPSMT" size:fontSize],
NSParagraphStyleAttributeName : paragraphStyle,
};
[attString appendAttributedString:[[NSAttributedString alloc] initWithString:line attributes: attributes]];
fontSize += 10.0;
}
