UILabel自适应行数与高度


效果图:


 

 

- (void)viewDidLoad {

//初始化label
    UILabel *label = [[UILabel alloc]initWithFrame:CGRectMake(10, 10, kUI_SCREEN_WIDTH - 20, 100)];
    
    label.textAlignment = NSTextAlignmentLeft;
    
    label.numberOfLines = 0;
    
    label.lineBreakMode = NSLineBreakByWordWrapping;
    
    label.text = @"本店于十一期间特推出一系列优惠,限时限量敬请选购!沙发:钻石品质,首领风范!床垫:华贵典雅,彰显时尚!尊贵而不失奢华,典雅却不失自然!温馨和浪漫的生活,我们与你一同创造!";
    
    CGSize size = [label sizeThatFits:CGSizeMake(label.frame.size.width, MAXFLOAT)];
    
    label.frame =CGRectMake(10, 10, kUI_SCREEN_WIDTH - 20, size.height);
    
    label.font = [UIFont systemFontOfSize:14];
    
    [labelView addSubview:label];
    
    label.backgroundColor = [UIColor grayColor];

}

 

 

 

UILabel自适应行数与高度、封装好方法

效果图:

  UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(10, 70, kUI_SCREEN_WIDTH - 20, 20)];
    label.text = @"本店于十一期间特推出一系列优惠,限时限量敬请选购!沙发:钻石品质,首领风范!床垫:华贵典雅,彰显时尚!尊贵而不失奢华,典雅却不失自然!温馨和浪漫的生活,我们与你一同创造!";
    label.backgroundColor = [UIColor yellowColor];
    
    [self numberOfAdaptiveRowsUILabel:label systemFontOfSize:15.0f];
    
    [self.view addSubview:label];

 

 

 

- (CGSize )numberOfAdaptiveRowsUILabel:(UILabel *)label systemFontOfSize:(CGFloat )font{
    label.textAlignment = NSTextAlignmentLeft;
    
    label.numberOfLines = 0;
    
    label.lineBreakMode = NSLineBreakByWordWrapping;
    
    CGSize size = [label sizeThatFits:CGSizeMake(label.frame.size.width, MAXFLOAT)];
    
    label.frame =CGRectMake(label.frame.origin.x, label.frame.origin.y, label.frame.size.width, size.height);
    
    label.font = [UIFont systemFontOfSize:font];
    
    return size;
    
    
    
    
}
