1.声明

//// NSString+Iphone.h// 旺旺好房//

#import<Foundation/Foundation.h>

@interface NSString (Iphone)

/** 判断手机类型 */

+ (NSString *)iphoneType;

/** 从字符串提取数字 */

+ (NSString *)extractingNumFormString:(NSString *)string;

/** 判断是否是非空字符串 */

+ (BOOL)isBlankString:(NSString *)string;

/** 判断是否是非0非空字符串 */

+ (BOOL)isZeroBlankString:(NSString *)string;

/**

删除字符串中特定字符

*/

+ (NSString *)stringDeleteString:(NSString *)str;

/**

正则判断手机号位数

@param str 带判断的手机号

@return BOOL

*/

+ (BOOL)isValidPhoneNumber:(NSString*)str;

/**

正则判断是否是手机

@param str 带判断的手机号

@return BOOL

*/

#warning 残缺用下面那个吧

+ (BOOL)wl_isMobileNumberClassification:(NSString *)tel;

/**

正则判断是否手机号（自带提示框）

@param str 带判断的手机号

@return BOOL

*/

+ (BOOL)checkTel:(NSString *)str;

@end

2.实现
