sizewithfont

I see some UIStringDrawing methods have been updated to use NSLineBreakMode instead of UILineBreakMode in iOS 6.0: E.g. - (CGSize)sizeWithFont:(UIFont *)font constrainedToSize:(CGSize)size lineBreakMode:(NSLineBreakMode)lineBreakMode How can I check for this to ensure my iOS 5 users and below continue to use UILineBreakMode? No checking is necessary. These are just enums and they map to the same values You can see there is no real difference here: UILineBreakMode vs NSLineBreakMode enum { NSLineBreakByWordWrapping = 0, NSLineBreakByCharWrapping, NSLineBreakByClipping,

I am getting the text size of a string with this textSize = [[tempDict valueForKeyPath:@"caption.text"] sizeWithFont:[UIFont systemFontOfSize:12] constrainedToSize:CGSizeMake(280, CGFLOAT_MAX) lineBreakMode: NSLineBreakByWordWrapping]; The only problem I have is that if the string only contains an emoji, my app crashes. Is there an easy way to check for emojis or do I have to create an array with all possible emojis and then check for them using that? error: -[NSNull sizeWithFont:constrainedToSize:lineBreakMode:]: unrecognized selector sent to instance 0x3aa88a60 if ([tempDict valueForKeyPath:

I'm drawing multiple 'pages' of imagery using a CGContext in the iOS. I've used sizeWithFont and drawInRect combinations extensively in my app. What I need to do is split a large chunk of text across multiple pages. I can size it and work out whether or not it needs another page but how do I know where to chop it? Do I have to do an ugly loop to check word by word until I find a string length that perfectly fits the page and then chop the string at that point? Is there a smarter way? Any ideas? Thanks. The NSString additions to UIKit for drawing text, you can pre-determine the exact amount of

All my research so far seems to indicate it is not possible to do this accurately. The only two options available to me at the outset were: a) Using a Layout manager for the CATextLayer - not available on iOS as of 4.0 b) Use sizeWithFont:constrainedToSize:lineBreakMode: and adjust the frame of the CATextLayer according to the size returned here. Option (b), being the simplest approach, should work. After all, it works perfectly with UILabels. But when I applied the same frame calculation to CATextLayer, the frame was always turning out to be a bit bigger than expected or needed. As it turns

In iOS 7, the method: - (CGSize)sizeWithFont:(UIFont *)font constrainedToSize:(CGSize)size lineBreakMode:(NSLineBreakMode)lineBreakMode and the method: - (CGSize)sizeWithFont:(UIFont *)font are deprecated. How can I replace CGSize size = [string sizeWithFont:font constrainedToSize:constrainSize lineBreakMode:NSLineBreakByWordWrapping]; and: CGSize size = [string sizeWithFont:font]; Xavier Maroñas You could try this: CGRect textRect = [text boundingRectWithSize:size options:NSStringDrawingUsesLineFragmentOrigin attributes:@{NSFontAttributeName:FONT} context:nil]; CGSize size = textRect.size;
