IOS 记下来以后用

1、判断纯中文

+ (BOOL) validateNickname:(NSString *)nickname

{

NSString *nicknameRegex = @"^[\u4e00-\u9fa5]{1,4}$";

NSPredicate *pred = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", nicknameRegex];

BOOL isMatch = [pred evaluateWithObject:nickname];

return isMatch;

}

//{1,4}是1到4个汉字

2、密码有效性检查

+ (BOOL)isPassword:(NSString *)password

{

NSRegularExpression *regex = [NSRegularExpression regularExpressionWithPattern:@"^[a-zA-Z0-9]{6,30}$"options:NSRegularExpressionCaseInsensitive error:nil];

if (regex != nil) {

NSUInteger numberOfMatch = [regex numberOfMatchesInString:password options:0 range:NSMakeRange(0, [password length])];

if (numberOfMatch == 0) {

return NO;

}

return YES;

}

3、按照时间排序

for (int i = 0; i < count; i++)
{//将数据添加进数组中
NSObject *object = [self.bubbleDataSource bubbleTableView:self dataForRow:i];
assert([object isKindOfClass:[NSBubbleData class]]);
[bubbleData addObject:object];
}

[bubbleData sortUsingComparator:^NSComparisonResult(id obj1, id obj2)//取数组中得实例进行判断
{
NSBubbleData *bubbleData1 = (NSBubbleData *)obj1;
NSBubbleData *bubbleData2 = (NSBubbleData *)obj2;

NSDateFormatter *inputFormatter = [[[NSDateFormatter alloc] init]autorelease];
[inputFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
NSDate* inputDate1 = [inputFormatter dateFromString:bubbleData1._date];
NSLog(@"date = %@", inputDate1);

NSDate* inputDate2 = [inputFormatter dateFromString:bubbleData2._date];
NSLog(@"date = %@", inputDate2);

return [inputDate1 compare:inputDate2];
//return [bubbleData1.date compare:bubbleData2.date];
}];

//返回排序好后的数组

4、

iOS 发布应用程序到App Store

5、推送 http://developer.baidu.com/wiki/index.php?title=docs/cplat/push/guideios&qq-pf-to=pcqq.c2c

6、判断当前网络是否存在

    Reachability*r = [ReachabilityreachabilityWithHostName:@"http://www.code4app.com"];
    switch([rcurrentReachabilityStatus]) {
        caseNotReachable:
            isExistenceNetwork=FALSE;
            break;
        caseReachableViaWWAN:
            isExistenceNetwork=TRUE;
            break;
        caseReachableViaWiFi:
            isExistenceNetwork=TRUE;
            break;
    }
     
    returnisExistenceNetwork;
}
