如果u不使用NSAttributeLabel然後 試試這個,它的作品對我來說很好
添加這個方法到CommonFuction類&添加此框架CoreText.framework
+ (void)setMultiColorAndFontText:(NSString *)text rangeString:(NSArray *)rangeString label:(UILabel*) label font:(NSArray*) fontName color:(NSArray*) colorName
{
label.layer.sublayers = nil;
NSMutableAttributedString *mutableAttributedString = [[ NSMutableAttributedString alloc]initWithString:text];
for (int i =0 ; i<[rangeString count]; i++)
{
CTFontRef ctFont = CTFontCreateWithName((__bridge CFStringRef) [UIFont fontWithName:[fontName objectAtIndex:i] size:10.0].fontName, [UIFont fontWithName:[fontName objectAtIndex:i] size:10.0].pointSize, NULL);
NSRange whiteRange = [text rangeOfString:[rangeString objectAtIndex:i]];
if (whiteRange.location != NSNotFound)
{
[mutableAttributedString addAttribute:(NSString *)kCTForegroundColorAttributeName value:(id)[colorName objectAtIndex:i] range:whiteRange];
[mutableAttributedString addAttribute:(NSString*)kCTFontAttributeName
value:(__bridge id)ctFont
range:whiteRange];
}
}
CGSize expectedLabelSize = [text sizeWithFont:[UIFont fontWithName:@"HelveticaNeue-CondensedBold" size:10.0f] constrainedToSize:CGSizeMake(186,100) lineBreakMode:UILineBreakModeWordWrap];
CATextLayer *textLayer = [[CATextLayer alloc]init];
textLayer.frame =CGRectMake(0,0, label.frame.size.width,expectedLabelSize.height+4);
textLayer.contentsScale = [[UIScreen mainScreen] scale];
textLayer.string=mutableAttributedString;
textLayer.opacity = 1.0;
textLayer.alignmentMode = kCAAlignmentLeft;
[label.layer addSublayer:textLayer];
[textLayer setWrapped:TRUE];
//label.lineBreakMode = UILineBreakModeWordWrap;
label.text = @"";
}
,並調用此方法如下之後: -
[CommonFunctions setMultiColorAndFontText:string rangeString:[NSArray arrayWithObjects:str1,str2,str3,str4,str5,str6, nil] label:yourLabel font:[NSArray arrayWithObjects:@"Arial",@"Arial",@"Arial",@"Arial",@"Arial",@"Arial"nil] color:[NSArray arrayWithObjects:(UIColor *)[UIColor colorWithRed:(0/255.f) green:(167/255.f) blue:(230/255.f) alpha:1.0f].CGColor,(UIColor *)[UIColor colorWithRed:(189/255.f) green:(189/255.f) blue:(189/255.f) alpha:1.0f].CGColor, color3,color4,color5,color6,nil]];
我希望它會工作得很好ü

您不能在單個標籤中執行此操作。你需要7個不同的標籤 – 2013-05-08 11:28:39
使用NSAttributedString你可以在ios6中做到這一點uilabel具有attributesString屬性。 – 2013-05-08 11:30:03
下面的ios 6.0使用TTAtributeLabel來顯示attributesString。 – 2013-05-08 11:31:54
