整形文字列の変換:
Convert Integer to NSString:
Convert NSString to C Integer:
Convert Integer to NSString:
int Value = 112;
NSString *ValueString = [NSString stringWithFormat:@"%d", Value]; Convert NSString to C Integer:
int Value = 112;
int ValueString = [Value int Value]; char *ValueasCString = (char *)[ValueString UTF8String];
:
searchモード: 1 + (NSString *)getDomainOfEmailAddress:(NSString *)email
2 {
3 NSString *re = @"(?<=@)((?:[A-Za-z0-9]+(?:[\\-|\\.][A-Za-z0-9]+)*)+\\.[A-Za-z]{2,6})$";
4 NSRange range = [email rangeOfString:re options:NSRegularExpressionSearch];
5 if (range.location != NSNotFound) {
6 return [email substringWithRange:range];
7 }
8 else {
9 return nil;
10 }
11 }
matchモード:+ (BOOL)isEmailAddress:(NSString *)email
{
NSString *re = @"^([A-Za-z0-9\\.\\-_]{1,})@((?:[A-Za-z0-9]+(?:[\\-|\\.][A-Za-z0-9]+)*)+\\.[A-Za-z]{2,6})$";
NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", re];
return [emailTest evaluateWithObject:email];
}

:char temp [100] = {0};
scanf("%s",temp);
NSString *str = [NSString stringWithUTF8String:temp];
