iphone - 我怎样才能传递 UIColor 的名字

Question

我想知道如何将 UIColor 的名称传递给特定方法？

编辑:

- (id) setLabel:(NSString *)text WithColorName:(NSString *)nameOfColor FontName:(NSString *)f_name FontSize:(float)f_size abel:(UILabel *)templbl
{
  templbl.backgroundColor = [UIColor ?????];

return templbl;

}

有什么建议吗？

谢谢..

NSString *colorStr = @"magenta";

NSString *selectorString = [colorStr stringByAppendingString:@"Color"];
SEL selector = NSSelectorFromString(selectorString);
UIColor *color = [UIColor blackColor];
if ([UIColor respondsToSelector:selector]) {
    color = [UIColor performSelector:selector];
}
