自己總結(jié)，歡迎指正，不喜勿噴

2017.03.05-2017.05.23

1.融云獲取最后一條消息的內(nèi)容

RCConversation *conversation = [[RCIMClient sharedRCIMClient]getConversation:ConversationType_PRIVATE targetId:[NSString stringWithFormat:@"%lu",(long)model.trainee_id]];
    if ([conversation.senderUserId isEqualToString:[[RCIM sharedRCIM]currentUserInfo].userId]) {
        cell.timeLabel.text = [self timestampConversionDate:conversation.sentTime/1000];
    }else {
        if (conversation.receivedTime != 0) {
            cell.timeLabel.text = [self timestampConversionDate:conversation.receivedTime/1000];
        }else {
            cell.timeLabel.text = @"00:00";
        }
    }
    if (conversation.unreadMessageCount > 0) {
        cell.statusView.hidden = NO;
    }else {
        cell.statusView.hidden = YES;
    }
    if ([conversation.lastestMessage isKindOfClass:[RCTextMessage class]]) {
        cell.contentLabel.text =((RCTextMessage *)conversation.lastestMessage).content;
    }else if ([conversation.lastestMessage isMemberOfClass:[RCVoiceMessage class]]) {
        cell.contentLabel.text = @"[語(yǔ)音]";
    }else if([conversation.lastestMessage isMemberOfClass:[RCLocationMessage class]]) {
        cell.contentLabel.text =((RCLocationMessage *)conversation.lastestMessage).locationName;
    }else if([conversation.lastestMessage isMemberOfClass:[RCImageMessage class]]) {
        cell.contentLabel.text = @"[圖片]";
    }else {
        cell.contentLabel.text = @"暫無(wú)聊天信息";
    }

2.與Android對(duì)接是需帶上用戶信息

///連接融云
- (void) rongCloudSetting {
    NSString *token = [[NSUserDefaults standardUserDefaults]objectForKey:k_Rong_Token];
    [[RCIM sharedRCIM] connectWithToken:token success:^(NSString *userId) {
        NSLog(@"***登錄成功");
        RCUserInfo *userinfo = [[RCUserInfo alloc]initWithUserId:[RCIM sharedRCIM].currentUserInfo.userId name: [[NSUserDefaults standardUserDefaults] objectForKey:k_User_Name] portrait:[[NSUserDefaults standardUserDefaults] objectForKey:k_User_HeadImage]];
        [[RCIM sharedRCIM] setCurrentUserInfo:userinfo];
        [[RCIM sharedRCIM] setEnableMessageAttachUserInfo:YES];
    } error:^(RCConnectErrorCode status) {
        NSLog(@"***登錄失敗");
    } tokenIncorrect:^{
        NSLog(@"token過(guò)期或不正確");
    }];
}

3.提交數(shù)據(jù)時(shí)主window蒙一層防重點(diǎn)

//FactoryClass為自己定義的工廠類
- (void) addFaceViewSetting {
    UIWindow *keywindow = [[UIApplication sharedApplication] keyWindow];
    self.loadBgView = [FactoryClass CreateView:0 Rounded:0 ToView:keywindow];
    self.loadBgView.backgroundColor  = [UIColor colorWithWhite:0 alpha:0.25];
    [self.loadBgView mas_makeConstraints:^(MASConstraintMaker *make) {
        make.left.right.top.equalTo(keywindow);
        make.bottom.equalTo(keywindow);
    }];
    self.loadBgView.hidden = YES;
    UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(tapNoClickEvent)];
    tap.delegate = self;
    [self.loadBgView addGestureRecognizer:tap];
}

4. 比較時(shí)間

- (NSInteger) compareStr:(NSString *)timeStr{
    if (timeStr.length < 22) {
        return -2;
    }
    NSString *dayStr = [timeStr substringToIndex:10];
    NSString *hourOneStr = [timeStr substringToIndex:16];
    NSString *hourStr = [timeStr substringFromIndex:timeStr.length - 5];
    NSString *houTwoStr = [NSString stringWithFormat:@"%@ %@",dayStr,hourStr];
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    [dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm"];
    NSString *currentDateStr = [dateFormatter stringFromDate:[NSDate date]];
    NSDate *dateA = [dateFormatter dateFromString:hourOneStr];
    NSDate *dateB = [dateFormatter dateFromString:houTwoStr];
    NSDate *dateC = [dateFormatter dateFromString:currentDateStr];
    NSComparisonResult result_1 = [dateC compare:dateA];
    NSComparisonResult result_2 = [dateC compare:dateB];
    //相等
    if (result_1 == NSOrderedAscending) {
        return -1;
    }
    //在某個(gè)時(shí)間段內(nèi)
    if ((result_1 == NSOrderedDescending || result_1 == NSOrderedSame)&&(result_2 == NSOrderedAscending || result_2 == NSOrderedSame)) {
        return 0;
    }
    //超過(guò)了某個(gè)時(shí)間
    else if (result_2 == NSOrderedDescending){
        return 1;
    }
    return -2;
}

5.高級(jí)控件控制其某類cell是否可以被點(diǎn)擊

//開啟高級(jí)控件的多選
self.collectionView.allowsMultipleSelection = YES;
//是否可以被點(diǎn)擊
if (schedule.order == -1) {
                cell.userInteractionEnabled = NO;
                cell.bgView.backgroundColor = [UIColor colorWithRGB:color(FFFFFF)];
            }else if(schedule.order == -2) {
                cell.userInteractionEnabled = YES;
                cell.bgView.backgroundColor = [UIColor colorWithRGB:color(FFB300)];
            }else if(schedule.order == 0) {
                cell.userInteractionEnabled = YES;
                cell.bgView.backgroundColor = [UIColor colorWithRGB:color(65C66E)];
            }else if(schedule.order > 0) {
                cell.userInteractionEnabled = YES;
                cell.bgView.backgroundColor = [UIColor colorWithRGB:[UIColor colorWithMain]];
            }else {
                cell.userInteractionEnabled = NO;
                cell.bgView.backgroundColor = [UIColor colorWithRGB:color(FFFFFF)];
            }
 }

6.創(chuàng)建帶有圖片的富文本

- (NSAttributedString *) insertImageWithLabel:(NSString *)imageName Text:(NSString *)text {
    // 創(chuàng)建一個(gè)富文本
    NSMutableAttributedString *attri = [[NSMutableAttributedString alloc] initWithString:[NSString stringWithFormat:@"%@ ",text]];
    [attri addAttributes:@{NSForegroundColorAttributeName:[UIColor colorWithRGB:[UIColor colorWithMain]]} range:NSMakeRange(0, attri.length)];
    // 添加表情
    NSTextAttachment *attch = [[NSTextAttachment alloc] init];
    // 表情圖片
    attch.image = [UIImage imageNamed:imageName];
    // 設(shè)置圖片大小
    attch.bounds = CGRectMake(0, 0, Size(16), Size(30));
    // 創(chuàng)建帶有圖片的富文本
    NSAttributedString *string = [NSAttributedString attributedStringWithAttachment:attch];
    [attri insertAttributedString:string atIndex:attri.length];
    //返回
    return attri;
}

7. 時(shí)間字符串轉(zhuǎn)某種格式

///NSString轉(zhuǎn)NSDate
- (NSDictionary *) stringConverseDate:(NSString *)dateStr {
    if (dateStr == nil) {
        return nil;
    }
    //需要轉(zhuǎn)換的字符串
    NSString *dateString = dateStr;
    //設(shè)置轉(zhuǎn)換格式
    NSDateFormatter *formatter = [[NSDateFormatter alloc] init] ;
    [formatter setDateFormat:@"yyyy-MM-dd"];
    //NSString轉(zhuǎn)NSDate
    NSDate *date=[formatter dateFromString:dateString];
    
    NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
    [dateFormat setDateFormat:@"EEE"];
    NSString *weekStr = [dateFormat stringFromDate:date];
    [dateFormat setDateFormat:@"MM-dd"];
    NSString *dayStr = [dateFormat stringFromDate:date];
    if (weekStr == nil || dayStr == nil) {
        return nil;
    }
    
    //判斷當(dāng)前手機(jī)系統(tǒng)的語(yǔ)言選擇
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    NSArray *languages = [defaults objectForKey:@"AppleLanguages"];
    NSString *currentLanguage = [languages objectAtIndex:0];
    if ([currentLanguage isEqualToString:@"zh_Hans"]) {
        NSString *weekRstr = [NSString stringWithFormat:@"周%@",[weekStr substringFromIndex:weekStr.length-1]];
        return [[NSDictionary alloc]initWithObjectsAndKeys:weekRstr,@"Week",dayStr,@"MandD", nil];
    }else {
        return [[NSDictionary alloc]initWithObjectsAndKeys:weekStr,@"Week",dayStr,@"MandD", nil];
    }
}

8.移除鍵盤通知和定時(shí)器

- (void)dealloc {
    [self.codeTimer invalidate];
    self.codeTimer = nil;
    [[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillChangeFrameNotification object:nil];
}

9.限制輸入框的輸入長(zhǎng)度和限制輸入字符

#pragma mark - UITextFieldDeledate 
- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {
    NSString * toBeString = [textField.text stringByReplacingCharactersInRange:range withString:string];
    if (textField == self.phoneTextField) {
        if (toBeString.length > 11) {
            return NO;
        }
    }
    if (textField == self.codeTextField) {
        if (toBeString.length > 6) {
            return NO;
        }
    }
    if (textField == self.passwordTextField) {
        if (toBeString.length > 22) {
            return NO;
        }
    }
    if (textField == self.againPasswordTextField) {
        if (toBeString.length > 22) {
            return NO;
        }
    }
    //如果輸入的字符串不滿足某種格式就不能輸入
    if (![YFWLValidationMessage checkUserName:((UITextField *)self.textFieldArray[0]).text]) {
        [YFWLHUDManager showInfoMessage:@"姓名格式錯(cuò)誤" duration:1.3];
        return NO;
    }
    return YES;
}

10.正則匹配手機(jī)號(hào)、身份證、密碼和銀行卡等格式

#pragma 正則匹配手機(jī)號(hào)

    char c;
    for (int i = 0; i < cardNumber.length; i++)
    {
        c = [cardNumber characterAtIndex:i];
        if (isdigit(c))
        {
            digitsOnly =[digitsOnly stringByAppendingFormat:@"%c",c];

        sum += addend;
        timesTwo = !timesTwo;
    }
    int modulus = sum % 10;
    return modulus == 0;

14.給UIColor添加類別

使用實(shí)例：
///導(dǎo)航欄的顏色值
+ (UIColor *)colorWithNavigationBar {
    return [UIColor colorWithRGB:color(CB3340)];
}

#pragma 十六進(jìn)制轉(zhuǎn)RGB值
+ (UIColor *)colorWithRGB:(uint32_t)rgbValue {
    return [UIColor colorWithRed:((rgbValue & 0xFF0000) >> 16) / 255.0f
                           green:((rgbValue & 0xFF00) >> 8) / 255.0f
                            blue:(rgbValue & 0xFF) / 255.0f
                           alpha:1];
}
#pragma 十六進(jìn)制轉(zhuǎn)RGBA值
+ (UIColor *)colorWithRGBA:(uint32_t)rgbaValue {
    return [UIColor colorWithRed:((rgbaValue & 0xFF000000) >> 24) / 255.0f
                           green:((rgbaValue & 0xFF0000) >> 16) / 255.0f
                            blue:((rgbaValue & 0xFF00) >> 8) / 255.0f
                           alpha:(rgbaValue & 0xFF) / 255.0f];
}
#pragma 十六進(jìn)制轉(zhuǎn)RGBA值
+ (UIColor *)colorWithRGB:(uint32_t)rgbValue alpha:(CGFloat)alpha {
    return [UIColor colorWithRed:((rgbValue & 0xFF0000) >> 16) / 255.0f
                           green:((rgbValue & 0xFF00) >> 8) / 255.0f
                            blue:(rgbValue & 0xFF) / 255.0f
                           alpha:alpha];
}
