1、數字字符校驗

#define?NUMBERSPERIOD?@"0123456789."??

-?(BOOL)CheckInput:(NSString?*)string?{ ?

? ?NSCharacterSet?*cs; ? ??

? ? cs?=?[[NSCharacterSet?characterSetWithCharactersInString:NUMBERSPERIOD]?invertedSet];?????

????NSString?*filtered?=?[[string?componentsSeparatedByCharactersInSet:cs]?componentsJoinedByString:@""];??

????BOOL?basicTest?=?[string?isEqualToString:filtered];??

????return?basicTest;?????

}??

2、判斷用戶名，在2－16位

-?(BOOL)CheckInput:(NSString?*)text?{??

????NSString*Regex?=?@"^\\w{2,16}{1}";??

????NSPredicate?*emailTest?=?[NSPredicate?predicateWithFormat:@"SELFMATCHES?%@",?Regex];??

????return?[emailTest?evaluateWithObject:text];??

}??

?3、判斷手機號碼，1開頭的十一位數字

-?(BOOL)CheckInput:(NSString?*)text?{??

????NSString?*Regex?=?@"1\\d{10}";??

????NSPredicate?*emailTest?=?[NSPredicate?predicateWithFormat:@"SELFMATCHES?%@",?Regex];??

????return?[emailTest?evaluateWithObject:text];??

}??

4、判斷郵箱

-?(BOOL)CheckInput:(NSString?*)text?{??

????NSString?*Regex?=?@"[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,4}";??

????NSPredicate?*emailTest?=?[NSPredicate?predicateWithFormat:@"SELFMATCHES?%@",?Regex];??

????return?[emailTest?evaluateWithObject:text];??

}??

?5、判斷密碼，6－16位

-?(BOOL)CheckInput:(NSString?*)text??

{??

????NSString?*Regex?=?@"\\w{6,16}";??

????NSPredicate?*emailTest?=?[NSPredicate?predicateWithFormat:@"SELFMATCHES?%@",?Regex];??

????return?[emailTest?evaluateWithObject:text];??

} ?
