一些好用的函数

这次介绍一些好用的函数

//计算绝对值的     fabs(<#double#>)

CGFloat spacingX = fabs(_tempMoveCell.center.x - cell.center.x);

  + (NSString *)transform:(NSString *)chinese{ 


    NSMutableString *pinyin = [chinese mutableCopy]; CFStringTransform((__bridge CFMutableStringRef)pinyin, NULL, kCFStringTransformMandarinLatin, NO); 

  CFStringTransform((__bridge CFMutableStringRef)pinyin, NULL, kCFStringTransformStripCombiningMarks, NO); NSLog(@"%@", pinyin);
   return [pinyin uppercaseString];}
