Question

如何使得Label里的字符有不同的颜色

Answer 1

//设置颜色属性和字体属性
- (NSAttributedString *)illuminatedString:(NSString *)text
font:(UIFont *)AtFont{

int len = [text length];
//创建一个可变的属性字符串
NSMutableAttributedString *mutaString = [[[NSMutableAttributedString alloc] initWithString:text] autorelease];
//改变字符串 从1位 长度为1 这一段的前景色，即字的颜色。

[mutaString addAttribute:(NSString *)(kCTForegroundColorAttributeName)
value:(id)self.stringColor.CGColor
range:NSMakeRange(0, len)];

if (self.keywordColor != nil)
{
for (NSValue *value in list)
{
// NSValue *value = [list objectAtIndex:i];
NSRange keyRange = [value rangeValue];
[mutaString addAttribute:(NSString *)(kCTForegroundColorAttributeName)
value:(id)self.keywordColor.CGColor
range:keyRange];
}
}
