NSNumber判断数值对象类型

if([value isKindOfClass:[NSNumber class]]){if (strcmp([value objCType], @encode(float)) == 0) {[cell.detailTextLabel.text =  [NSString stringWithFormat:@"%.3f", [value floatValue]]];} else if (strcmp([value objCType], @encode(double)) == 0) {[self.subTitleString appendString:[NSString stringWithFormat:@"%.3f", [value floatValue]]];}else if (strcmp([value objCType], @encode(int)) == 0) {[self.subTitleString appendString:[NSString stringWithFormat:@"%d", [value intValue]]];}else [self.subTitleString appendString: [NSString stringWithFormat:@"%d", [value intValue]]];}
