Objective-C语法之NSPredicate的使用

正则表达式判断手机号码和电话号码的方法：

 #import <Foundation/Foundation.h>

正则表达式判断姓名（只允许包含中文或英文字母，10个字符以内）的方法：

 + (BOOL)isValidateName:(NSString *)name {
     NSString *nameRegex = @"^[\u4E00-\u9FA5A-Za-z]{1,10}";
     NSPredicate *namePredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", nameRegex];
     return [namePredicate evaluateWithObject:name];
 }
