一：使用方式
二：实现方法
BasisYYLableCalculationHeightAndWidth.h
#import#import@interface BasisYYLableCalculationHeightAndWidth : NSObject
/**
* @param message lable.text
* @param lable (YYLabel *)label
* @return lable的高度
*/
+ (CGFloat)getLableHeight:(NSString *)message yyLabel:(YYLabel *)lable lineSpacing:(CGFloat)lineSpace stringFont:(UIFont *)font;
/**
* @param message lable.text
* @param lable (YYLabel *)label
* @return lable的宽度
*/
+ (CGFloat)getLableWidth:(NSString *)message yyLabel:(YYLabel *)lable stringFont:(UIFont *)font;
@end
BasisYYLableCalculationHeightAndWidth.m
#import "BasisYYLableCalculationHeightAndWidth.h"#import@implementation BasisYYLableCalculationHeightAndWidth
+ (CGFloat)getLableHeight:(NSString *)message yyLabel:(YYLabel *)lable lineSpacing:(CGFloat)lineSpace stringFont:(UIFont *)font;
{
NSMutableAttributedString *introText = [[NSMutableAttributedString alloc] initWithString:message];
introText.yy_font = font;
introText.yy_lineSpacing = lineSpace;//行间距
lable.attributedText = introText;
CGSize introSize = CGSizeMake(lable.frame.size.width, CGFLOAT_MAX);
YYTextLayout *layout = [YYTextLayout layoutWithContainerSize:introSize text:introText];
lable.textLayout = layout;
CGFloat introHeight = layout.textBoundingSize.height;
return introHeight;
}
+ (CGFloat)getLableWidth:(NSString *)message yyLabel:(YYLabel *)lable stringFont:(UIFont *)font;
{
NSMutableAttributedString *introText = [[NSMutableAttributedString alloc] initWithString:message];
introText.yy_font = font;
lable.attributedText = introText;
CGSize introSize = CGSizeMake(CGFLOAT_MAX, lable.frame.size.height);
YYTextLayout *layout = [YYTextLayout layoutWithContainerSize:introSize text:introText];
lable.textLayout = layout;
CGFloat introWidth = layout.textBoundingSize.width;
return introWidth;
}
@end
