一般用富文本实现多种花样的Label文字，下图是利用UILabel分类快速创建的多彩多样lable文字，快速简单，自定义性强，更重要的是无代码污染

新加2个方法
*自定义添加*/ - (void) setFont:(UIFont *)font substring:(NSString*)substring; - (void) setFont:(UIFont *)font WithtColor:(UIColor *)textColor substring:(NSString*)substring;
/**
* 自定义添加
*/
- (void) setFont:(UIFont*)font substring:(NSString*)substring {
NSRange range = [self.text rangeOfString:substring];
if (range.location != NSNotFound)
{
[self setFont:font range:range];
}
}
- (void) setFont:(UIFont *)font WithtColor:(UIColor *)textColor substring:(NSString*)substring
{
NSRange range = [self.text rangeOfString:substring];
if (range.location != NSNotFound)
{
[self setFont:font range:range];
[self setTextColor:textColor range:range];
}
}
使用
- (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. self.view.backgroundColor=[UIColor blackColor]; NSString *text=@"思埠集团于2015年1月6日正式入股本土第一家在新三板上市日化企业——幸美股份(代码830929)，成为幸美最大股东。广东思埠集团直接控股新三板挂牌上市公司幸美股份，正式成为准上市公司。"; UILabel *labelA = [[UILabel alloc] init]; [labelA setFrame:CGRectMake(0, 15, self.view.frame.size.width,25)]; [labelA setBackgroundColor:[UIColor clearColor]]; [labelA setTextAlignment:NSTextAlignmentCenter]; [labelA setText:@"Color Label"]; [labelA setTextColor:[UIColor cyanColor]]; [labelA setFont:[UIFont systemFontOfSize:22]];; [labelA setTextColor:[UIColor redColor] String:@"Color"]; [self.view addSubview:labelA]; // Colors UILabel *labelC = [[UILabel alloc] init]; [labelC setFrame:CGRectMake(0, 30, self.view.frame.size.width, floorf(self.view.frame.size.height / 5))]; [labelC setBackgroundColor:[UIColor clearColor]]; [labelC setTextAlignment:NSTextAlignmentCenter]; [labelC setText:text]; [labelC setNumberOfLines:2]; [labelC setTextColor:[UIColor yellowColor]]; [labelC setFont:[UIFont fontWithName:@"Courier" size:14]]; [labelC setTextColor:[UIColor whiteColor] range:NSMakeRange(20, 3)]; [labelC setTextColor:[UIColor cyanColor] range:NSMakeRange(28, 4)]; [labelC setTextUnderLine:[UIColor redColor] range:NSMakeRange(10, 6)]; [self.view addSubview:labelC]; // Fonts UILabel *labelF = [[UILabel alloc] init]; [labelF setFrame:CGRectMake(0, floorf(self.view.frame.size.height / 4), self.view.frame.size.width, floorf(self.view.frame.size.height / 3))]; [labelF setBackgroundColor:[UIColor clearColor]]; [labelF setTextAlignment:NSTextAlignmentCenter]; [labelF setText:text]; [labelF setNumberOfLines:2]; [labelF setTextColor:[UIColor yellowColor]]; [labelF setFont:[UIFont fontWithName:@"Courier" size:14]]; [labelF setTextColor:[UIColor redColor] String:@"幸美股份"]; [labelF setFont:[UIFont systemFontOfSize:20] WithtColor:[UIColor whiteColor] substring:@"思埠集团"]; [self.view addSubview:labelF]; // Colors AND Fonts UILabel *labelCF = [[UILabel alloc] init]; [labelCF setFrame:CGRectMake(0, floorf(self.view.frame.size.height * 2 / 4), self.view.frame.size.width, floorf(self.view.frame.size.height / 3))]; [labelCF setBackgroundColor:[UIColor clearColor]]; [labelCF setTextAlignment:NSTextAlignmentCenter]; [labelCF setText:text]; [labelCF setNumberOfLines:2]; [labelCF setTextColor:[UIColor yellowColor]]; [labelCF setFont:[UIFont fontWithName:@"Courier" size:14]]; [labelCF setTextColor:[UIColor redColor] range:NSMakeRange(20, 8)]; [labelCF setFont:[UIFont fontWithName:@"Courier-Bold" size:14] range:NSMakeRange(20, 8)]; [labelCF setTextColor:[UIColor cyanColor] range:NSMakeRange(33, 11)]; [labelCF setFont:[UIFont fontWithName:@"Courier-Oblique" size:14] range:NSMakeRange(33, 11)]; [self.view addSubview:labelCF]; }
