时间:2021-02-05 04:20:47

1.text:设置标签显示文本。

2.attributedText:设置标签属性文本。

NSString *text = @"first";  

NSMutableAttributedString *textLabelStr = [[NSMutableAttributedString alloc] initWithString:text];  

[textLabelStr setAttributes:@{

                               NSForegroundColorAttributeName : [UIColor lightGrayColor],   

                               NSFontAttributeName : [UIFont systemFontOfSize:17]

                             } range:NSMakeRange(11, 10)];

label.attributedText = textLabelStr;

3.font:设置标签文本字体。

默认是系统自带字体,大小为17。

label.font = [UIFont systemFontOfSize:17]

label.font = [UIFont fontWithName:@"Arial" size:16];  

label.textColor = [UIColor blueColor];

4.textAlignment:设置标签文本对齐方式。

label.textAlignment = NSTextAlignmentCenter;  

5.lineBreakMode:设置标签文字过长时的显示方式,这个属性使用于label中文本的换行和截短。首先numberofLines必须设置为0,才有效果。

Ios代码  

label.lineBreakMode = NSLineBreakByCharWrapping;以字符为显示单位显示,后面部分省略不显示。  

label.lineBreakMode = NSLineBreakByClipping;剪切与文本宽度相同的内容长度,后半部分被删除。  

label.lineBreakMode = NSLineBreakByTruncatingHead;前面部分文字以……方式省略,显示尾部文字内容。  

label.lineBreakMode = NSLineBreakByTruncatingMiddle;中间的内容以……方式省略,显示头尾的文字内容。  

label.lineBreakMode = NSLineBreakByTruncatingTail;结尾部分的内容以……方式省略,显示头的文字内容。  

label.lineBreakMode = NSLineBreakByWordWrapping;以单词为显示单位显示,后面部分省略不显示。  

比如:

label.numberOfLines = 0

label.lineBreakMode = NSLineBreakByTruncatingMiddle;
