더 이상 사용되지 않는 -sizeWithFont : constrainedToSize : lineBreakMode :를 iOS 7에서 대체 하시겠습니까?

---

iOS 7에서 방법은 다음과 같습니다.

- (CGSize)sizeWithFont:(UIFont *)font
     constrainedToSize:(CGSize)size
         lineBreakMode:(NSLineBreakMode)lineBreakMode 

그리고 방법 :

- (CGSize)sizeWithFont:(UIFont *)font

더 이상 사용되지 않습니다. 교체하는 방법

CGSize size = [string sizeWithFont:font
                 constrainedToSize:constrainSize
                     lineBreakMode:NSLineBreakByWordWrapping];

과:

CGSize size = [string sizeWithFont:font];

당신은 이것을 시도 할 수 있습니다 :

CGRect textRect = [text boundingRectWithSize:size
                                 options:NSStringDrawingUsesLineFragmentOrigin
                              attributes:@{NSFontAttributeName:FONT}
                                 context:nil];

CGSize size = textRect.size;

"[UIFont font ....]"에 대해 "FONT"를 변경하십시오.

4.3보다 큰 모든 iOS에 sizeWithAttributes를 사용할 수 없으므로 7.0 및 이전 iOS에 대한 조건부 코드를 작성해야합니다.

1) 해결책 1 :

if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0")) {
   CGSize size = CGSizeMake(230,9999);
   CGRect textRect = [specialityObj.name  
       boundingRectWithSize:size
                    options:NSStringDrawingUsesLineFragmentOrigin
                 attributes:@{NSFontAttributeName:[UIFont fontWithName:[AppHandlers zHandler].fontName size:14]}
                    context:nil];
   total_height = total_height + textRect.size.height;   
}
else {
   CGSize maximumLabelSize = CGSizeMake(230,9999); 
   expectedLabelSize = [specialityObj.name sizeWithFont:[UIFont fontWithName:[AppHandlers zHandler].fontName size:14] constrainedToSize:maximumLabelSize lineBreakMode:UILineBreakModeWordWrap]; //iOS 6 and previous. 
   total_height = total_height + expectedLabelSize.height;
}

2) 해결책 2

UILabel *gettingSizeLabel = [[UILabel alloc] init];
gettingSizeLabel.font = [UIFont fontWithName:[AppHandlers zHandler].fontName size:16]; // Your Font-style whatever you want to use.
gettingSizeLabel.text = @"YOUR TEXT HERE";
gettingSizeLabel.numberOfLines = 0;
CGSize maximumLabelSize = CGSizeMake(310, 9999); // this width will be as per your requirement

CGSize expectedSize = [gettingSizeLabel sizeThatFits:maximumLabelSize];

첫 번째 해결책은 때때로 적절한 높이 값을 반환하지 못하는 것입니다. 다른 솔루션을 사용하십시오. 완벽하게 작동합니다.

두 번째 옵션은 조건부 코드없이 모든 iOS에서 원활하게 작동합니다.

간단한 해결책은 다음과 같습니다.

요구 사항 :

CGSize maximumSize = CGSizeMake(widthHere, MAXFLOAT);
UIFont *font = [UIFont systemFontOfSize:sizeHere];

이제 iOS 7.0constrainedToSizeusage:lineBreakMode: 에서는 사용법이 더 이상 사용되지 않습니다 .

CGSize expectedSize = [stringHere sizeWithFont:font constrainedToSize:maximumSize lineBreakMode:NSLineBreakByWordWrapping];

이제 더 큰 iOS 7.0 버전에서의 사용법 은 다음과 같습니다.

// Let's make an NSAttributedString first
NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:stringHere];
//Add LineBreakMode
NSMutableParagraphStyle *paragraphStyle = [NSMutableParagraphStyle new];
[paragraphStyle setLineBreakMode:NSLineBreakByWordWrapping];
[attributedString setAttributes:@{NSParagraphStyleAttributeName:paragraphStyle} range:NSMakeRange(0, attributedString.length)];
// Add Font
[attributedString setAttributes:@{NSFontAttributeName:font} range:NSMakeRange(0, attributedString.length)];

//Now let's make the Bounding Rect
CGSize expectedSize = [attributedString boundingRectWithSize:maximumSize options:NSStringDrawingUsesLineFragmentOrigin context:nil].size;

In most cases I used the method sizeWithFont:constrainedToSize:lineBreakMode: to estimate the minimum size for a UILabel to accomodate its text (especially when the label has to be placed inside a UITableViewCell)...

...If this is exactly your situation you can simpy use the method:

CGSize size = [myLabel textRectForBounds:myLabel.frame limitedToNumberOfLines:mylabel.numberOfLines].size;

Hope this might help.

Below are two simple methods that will replace these two deprecated methods.

And here are the relevant references:

If you are using NSLineBreakByWordWrapping, you don't need to specify the NSParagraphStyle, as that is the default: https://developer.apple.com/library/mac/documentation/Cocoa/Reference/ApplicationKit/Classes/NSParagraphStyle_Class/index.html#//apple_ref/occ/clm/NSParagraphStyle/defaultParagraphStyle

You must get the ceil of the size, to match the deprecated methods' results. https://developer.apple.com/library/ios/documentation/UIKit/Reference/NSString_UIKit_Additions/#//apple_ref/occ/instm/NSString/boundingRectWithSize:options:attributes:context:

+ (CGSize)text:(NSString*)text sizeWithFont:(UIFont*)font {    
    CGSize size = [text sizeWithAttributes:@{NSFontAttributeName: font}];
    return CGSizeMake(ceilf(size.width), ceilf(size.height));
}

+ (CGSize)text:(NSString*)text sizeWithFont:(UIFont*)font constrainedToSize:(CGSize)size{
    CGRect textRect = [text boundingRectWithSize:size
                                     options:NSStringDrawingUsesLineFragmentOrigin
                                  attributes:@{NSFontAttributeName: font}
                                     context:nil];
    return CGSizeMake(ceilf(textRect.size.width), ceilf(textRect.size.height));
}

UIFont *font = [UIFont boldSystemFontOfSize:16];
CGRect new = [string boundingRectWithSize:CGSizeMake(200, 300) options:NSStringDrawingUsesFontLeading attributes:@{NSFontAttributeName: font} context:nil];
CGSize stringSize= new.size;

[Accepted answer works nicely in a category. I'm overwriting the deprecated method names. Is this a good idea? Seems to work with no complaints in Xcode 6.x]

This works if your Deployment Target is 7.0 or greater. Category is NSString (Util)

NSString+Util.h

- (CGSize)sizeWithFont:(UIFont *) font;
- (CGSize)sizeWithFont:(UIFont *)font constrainedToSize:(CGSize)size;

NSString+Util.m

- (CGSize)sizeWithFont:(UIFont *) font {
    NSDictionary *fontAsAttributes = @{NSFontAttributeName:font};
    return [self sizeWithAttributes:fontAsAttributes];
}

- (CGSize)sizeWithFont:(UIFont *)font constrainedToSize:(CGSize)size {
    NSDictionary *fontAsAttributes = @{NSFontAttributeName:font};
    CGRect retVal = [self boundingRectWithSize:size
                                     options:NSStringDrawingUsesLineFragmentOrigin
                                  attributes:fontAsAttributes context:nil];
    return retVal.size;
}

UIFont *font = [UIFont fontWithName:@"Courier" size:16.0f];

NSMutableParagraphStyle *paragraphStyle = [[NSParagraphStyle defaultParagraphStyle] mutableCopy];
paragraphStyle.lineBreakMode = NSLineBreakByTruncatingTail;
paragraphStyle.alignment = NSTextAlignmentRight;

NSDictionary *attributes = @{ NSFontAttributeName: font,
                    NSParagraphStyleAttributeName: paragraphStyle };

CGRect textRect = [text boundingRectWithSize:size
                                 options:NSStringDrawingUsesLineFragmentOrigin
                              attributes:attributes
                                 context:nil];

CGSize size = textRect.size;
