How to change the first day of the week to monday in week view

[ranjith1109]

Hi,

I have changed the first day of the week to monday in the month view but am not able to do the same in the week view.I changed to monday by using the following syntax " self.monthView = [self.monthView initWithSundayAsFirst:NO] " .How to achieve this in weekview? Kindly guide me.Thank you.

Hi i fixed the above issue by editing two functions as below
This is to fix the day name :

- (void) _setupView{
    	self.nowLineView = [[TKNowView alloc] init];
	NSDateComponents *info = [[NSDate date] dateComponentsWithTimeZone:self.calendar.timeZone];
    info.weekday = 2;
	info.hour = info.minute = info.second = 0;
	self.formatter = [[NSDateFormatter alloc] init];
    self.formatter.timeZone = self.calendar.timeZone;
	self.eventGraveYard = [NSMutableArray array];
    self.backgroundColor = [UIColor whiteColor];
    self.clipsToBounds = YES;
    self.pages = [NSMutableArray arrayWithCapacity:3];
    self.weekdayPages = [NSMutableArray arrayWithCapacity:3];
    [self addSubview:self.horizontalScrollView];
	info.day -= 1;
	for(NSInteger i=0;i<3;i++){
		NSDate *date = [NSDate dateWithDateComponents:info];
		CGRect r = CGRectInset(self.horizontalScrollView.bounds, HORIZONTAL_PAD, 0);
		r.origin.x = CGRectGetWidth(self.horizontalScrollView.frame) * i + HORIZONTAL_PAD;
		r.origin.y = 0;
		CGRect rr = r;
		rr.origin.x = 0;
		UIScrollView *sv = [[UIScrollView alloc] initWithFrame:r];
		sv.autoresizingMask = UIViewAutoresizingFlexibleWidth;
		sv.clipsToBounds = NO;
		sv.tag = i;
		sv.contentSize = CGSizeMake(0, TIMELINE_HEIGHT);
		sv.alwaysBounceVertical = TRUE;
		sv.backgroundColor = [UIColor whiteColor];
		[self.horizontalScrollView addSubview:sv];
		TKTimelineView *timelineView = [[TKTimelineView alloc] initWithFrame:sv.bounds];
		timelineView.autoresizingMask = UIViewAutoresizingFlexibleWidth;
		[sv addSubview:timelineView];
		timelineView.date = date;
		[self.pages addObject:sv];
		info.day += 1;
	}
	self.currentDay = [self _timelineAtIndex:1].date;
    [self _updateDateLabel];
    [self addSubview:self.daysBackgroundView];
    [self addSubview:self.monthYearLabel];
	NSInteger cnt = 0;    
    NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];    
    dateFormat.dateFormat = @"eee";    
    dateFormat.timeZone = self.timeZone;    
    NSDateComponents *sund = [[NSDateComponents alloc] init];    
    sund.day = 5;    
    sund.month = 12;    
    sund.year = 2010;    
    sund.hour = sund.minute = sund.second = sund.weekday = 0;    
    sund.timeZone = self.timeZone;    
    NSString * sun = [dateFormat stringFromDate:[NSDate dateWithDateComponents:sund]];    
    sund.day = 6;
    NSString *mon = [dateFormat stringFromDate:[NSDate dateWithDateComponents:sund]];    
    sund.day = 7;
    NSString *tue = [dateFormat stringFromDate:[NSDate dateWithDateComponents:sund]];    
    sund.day = 8;
    NSString *wed = [dateFormat stringFromDate:[NSDate dateWithDateComponents:sund]];    
    sund.day = 9;
    NSString *thu = [dateFormat stringFromDate:[NSDate dateWithDateComponents:sund]];
    sund.day = 10;
    NSString *fri = [dateFormat stringFromDate:[NSDate dateWithDateComponents:sund]];    
    sund.day = 11;
    NSString *sat = [dateFormat stringFromDate:[NSDate dateWithDateComponents:sund]];    
    NSArray *ar;
    if(self.sunday) ar = @[sun,mon,tue,wed,thu,fri,sat];
    else ar = @[mon,tue,wed,thu,fri,sat,sun];    
	NSInteger per = CGFrameGetWidth(self) - (DAY_LABEL_WIDTH *7);
	per /= 7;
	NSInteger minX = per / 2;	
	for(NSString *str in ar){		
        UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(minX + cnt*(DAY_LABEL_WIDTH+per) , 0, DAY_LABEL_WIDTH, 20)];        
        if ([str isEqualToString:@"Sun"]) {
            label.accessibilityLabel = @"Sunday";
        }
        else if ([str isEqualToString:@"Mon"]) {
            label.accessibilityLabel = @"Monday";
        }
        else if ([str isEqualToString:@"Tue"]) {
            label.accessibilityLabel = @"Tuesday";
        }
        else if ([str isEqualToString:@"Wed"]) {
            label.accessibilityLabel = @"Wednesday";
        }
        else if ([str isEqualToString:@"Thu"]) {
            label.accessibilityLabel = @"Thursday";
        }
        else if ([str isEqualToString:@"Fri"]) {
            label.accessibilityLabel = @"Friday";
        }
        else if ([str isEqualToString:@"Sat"]) {
            label.accessibilityLabel = @"Saturday";
        }
		label.font = [UIFont systemFontOfSize:10];
        label.text = [str substringToIndex:1];		
        label.textColor = cnt == 0 || cnt == 6 ? WEEKEND_TEXT_COLOR : [UIColor blackColor];		
        label.textAlignment = NSTextAlignmentCenter;		
        label.userInteractionEnabled = NO;		
        [self.daysBackgroundView addSubview:label];		
        [label sizeToFitWithAlignment];
		cnt++;
	}	
	[self.daysBackgroundView addSubviewToBack:self.daysScrollView];	
	UIView *dayContainerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.daysScrollView.contentSize.width, CGRectGetHeight(self.daysScrollView.frame))];    
	[self.daysScrollView addSubview:dayContainerView];	
	CGRect weekFrame = self.daysScrollView.frame;	
    weekFrame.origin = CGPointZero;	
    for(NSInteger i=0;i<3;i++){		
		weekFrame.origin.x = CGRectGetWidth(weekFrame) * i;	
        TKWeekdaysView *weekdayView = [[TKWeekdaysView alloc] initWithFrame:weekFrame];		
		for(UILabel *label in weekdayView.weekdayLabels){		
            label.userInteractionEnabled = YES;			
            [label addGestureRecognizer:[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(didTapWeekdayLabel:)]];
		}		
        [dayContainerView addSubviewToBack:weekdayView];
        [self.weekdayPages addObject:weekdayView];
	}
}

This is to fix the dates :
- (void) _setupDaysView{
	NSArray *labels =  [self _allDayLabels];
    NSDateComponents *comp = [self.calendar components:NSCalendarUnitDay | NSCalendarUnitMonth | NSCalendarUnitYear | NSCalendarUnitEra | NSCalendarUnitWeekday fromDate:self.currentDay];
    NSDateComponents *mutedCom = [self.calendar components:NSCalendarUnitDay | NSCalendarUnitMonth | NSCalendarUnitYear | NSCalendarUnitEra fromDate:self.currentDay];
    for(NSInteger cnt= comp.weekday + 5;cnt>=0;cnt--){
        NSDate *aDate = [self.calendar dateFromComponents:mutedCom];
        mutedCom = [self.calendar components:NSCalendarUnitDay | NSCalendarUnitMonth | NSCalendarUnitYear | NSCalendarUnitEra fromDate:aDate];
        TKDateLabel *label = labels[cnt];
        label.text = [NSString stringWithFormat:@"%@",@(mutedCom.day)];
        label.date = aDate;
        label.today = [aDate isTodayWithTimeZone:self.calendar.timeZone];
        label.selected = [aDate isSameDay:self.currentDay timeZone:self.calendar.timeZone];
        mutedCom.day --;
	}
	mutedCom = [self.calendar components:NSCalendarUnitDay | NSCalendarUnitMonth | NSCalendarUnitYear | NSCalendarUnitEra fromDate:self.currentDay];
	for(NSInteger cnt= comp.weekday + 5;cnt<labels.count;cnt++){
		NSDate *aDate = [self.calendar dateFromComponents:mutedCom];
        mutedCom = [self.calendar components:NSCalendarUnitDay | NSCalendarUnitMonth | NSCalendarUnitYear | NSCalendarUnitEra fromDate:aDate];
        TKDateLabel *label = labels[cnt];
        label.text = [NSString stringWithFormat:@"%@",@(mutedCom.day)];
        label.date = aDate;
        label.today = [aDate isTodayWithTimeZone:self.calendar.timeZone];
        label.selected = [aDate isSameDay:self.currentDay timeZone:self.calendar.timeZone];
        mutedCom.day ++;
	}
	self.indexOfCurrentDay = comp.weekday-1;
}

I jus tried this and it worked out but if possible explain me the logic in the _setupDaysView function.Thank you.

@ranjith1109 I've made a library which gets first day of the week from user's current locale automatically:
