YYLabel實現(xiàn)方式
//1.簡單顯示label
YYLabel *label = [YYLabel new];
label.frame = CGRectMake(100,50,100,25);
label.font = [UIFont systemFontOfSize:14.0f];
label.textColor = [UIColororangeColor];
label.textAlignment=NSTextAlignmentCenter;
label.lineBreakMode=0;
label.numberOfLines = NSLineBreakByWordWrapping;
label.text=@"YYTextDemo Test";
//??? [self.view addSubview:label];
//2.屬性字符串 簡單實用
NSMutableAttributedString*text= [[NSMutableAttributedStringalloc] initWithString:@"上海市第九城市信息技術有限公司"];
text.font = [UIFontboldSystemFontOfSize:13.0f];
text.color = [UIColorblueColor];
[textsetColor:[UIColor redColor]range:NSMakeRange(0,4)];
//??? 給你的label添加點擊事件
[textsetTextHighlightRange:NSMakeRange(0,4)
color:[UIColor orangeColor]
backgroundColor:[UIColorwhiteColor]
tapAction:^(UIView *containerView, NSAttributedString *text, NSRange range, CGRect rect){
NSLog(@"tap text range:...");
}];
YYLabel *attributedLabel = [YYLabel new];
attributedLabel.frame = CGRectMake(100,100,160,25);
attributedLabel.attributedText = text;
attributedLabel.userInteractionEnabled=YES;
attributedLabel.backgroundColor = [UIColor purpleColor];
//??? [self.view addSubview:attributedLabel];
//3.圖文混排模式
NSMutableAttributedString *textImage = [NSMutableAttributedString new];
UIFont *font= [UIFont systemFontOfSize:14.0f];
inti =2;
switch(i) {
case0:
{
//??? 方式一
