在IOS中捕獲匹配的字符串匹配是由NSPREDICATE完成

Question

我有一個代碼來匹配正則表達式和我的string.once我執行代碼結果顯示匹配是YES。

任何一個可以幫助我在其他位置

單獨提取匹配的字符串這是低於

(void)viewDidLoad 
    { 
    NSString *string = @"@002@[00152-614[4000846555@"; 

    NSString *expression = @"[\-@0]{1}[0-9]{3}[\-@]{1}[\[0]{1}[0-9]{5}[\-0]{1}[0-9]{3,}[\[0]{1} [0-9\-]{7,}[@0]{1}"; 

    NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", expression]; 

    BOOL match = [predicate evaluateWithObject:string]; 

    if(match) NSLog(@"match is YES") ; 

    else NSLog(@"match is NO") ; 

    [super viewDidLoad]; 

} 

感謝我的代碼提前

問候

試試這個

- (BOOL) validateEmail: (NSString *)candidate { 
    NSString *emailRegex = @"[\-@0]{1}[0-9]{3}[\-@]{1}[\[0]{1}[0-9]{5}[\-0]{1}[0-9]{3,}[\[0]{1} [0-9\-]{7,}[@0]{1}"; 
    NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex]; 
    return [emailTest evaluateWithObject:candidate]; 
    }
