使用Tapku日历创建透明日历

[英]Create a transparent Calendar with Tapku Calendar

首先,我想感谢您在本网站上提供的所有有用答案。 我大约六个月前开始编程,而我学到的许多东西都是来自这里的问题/答案。

我正在iPhone项目中使用Tapku Library中的Calendar,并且希望日历磁贴是透明的,以便可以看到TKCalendarMonthView视图后面的视图。

我使用本杰明·皮尔森的本教程中的代码实现了TKCalendarMonthView。

然后我通过@Jacques删除了平铺图像并尝试了此答案中的代码,因此TKCalendarMonthView.m中的drawrect函数如下所示:

- (void) drawRect:(CGRect)rect {

//From Jacques' StackOverflow answer (I also put this in the init)
self.opaque = NO;
self.backgroundColor = [UIColor clearColor];


//From Jacques' answer
[[UIColor clearColor] setFill
 ];
UIRectFill(rect);

//Remove CGContextRef
    //CGContextRef context = UIGraphicsGetCurrentContext();
    //UIImage *tile = [UIImage imageWithContentsOfFile:TKBUNDLE(@"TapkuLibrary.bundle/Images/calendar/Month Calendar Date Tile.png")];

CGRect r = CGRectMake(0, 0, 46, 44);

//From Jacques' StackOverflow answer
[[UIColor clearColor] setFill];
UIRectFill(r);

//Remove this sense we won't use the tile image
//CGContextDrawTiledImage(context, r, tile.CGImage);


if(today > 0){
    int pre = firstOfPrev > 0 ? lastOfPrev - firstOfPrev + 1 : 0;
    int index = today +  pre-1;
    CGRect r =[self rectForCellAtIndex:index];
    r.origin.y -= 7;

    //Don't use image here
    //[[UIImage imageWithContentsOfFile:TKBUNDLE(@"TapkuLibrary.bundle/Images/calendar/Month Calendar Today Tile.png")] drawInRect:r];
}

int index = 0;

UIFont *font = [UIFont boldSystemFontOfSize:dateFontSize];
UIFont *font2 =[UIFont boldSystemFontOfSize:dotFontSize];

//Change the font for our dates:
font = [UIFont fontWithName:@"HelveticaNeue-Light" size:dateFontSize];
font2 = [UIFont fontWithName:@"HelveticaNeue-Light" size:dateFontSize];
UIColor *color = [UIColor grayColor];

if(firstOfPrev>0){
    [color set];
    for(int i = firstOfPrev;i<= lastOfPrev;i++){
        r = [self rectForCellAtIndex:index];
        if ([marks count] > 0)
            [self drawTileInRect:r day:i mark:[[marks objectAtIndex:index] boolValue] font:font font2:font2];
        else
            [self drawTileInRect:r day:i mark:NO font:font font2:font2];
        index++;
    }
}

//Set the color for all dates in the current month that are not today
color = [UIColor colorWithRed:59/255. green:73/255. blue:88/255. alpha:1];


[color set];
for(int i=1; i <= daysInMonth; i++){

    r = [self rectForCellAtIndex:index];
    if(today == i) [[UIColor whiteColor] set];

    if ([marks count] > 0) 
        [self drawTileInRect:r day:i mark:[[marks objectAtIndex:index] boolValue] font:font font2:font2];
    else
        [self drawTileInRect:r day:i mark:NO font:font font2:font2];
    if(today == i) [color set];
    index++;
}

[[UIColor grayColor] set];
int i = 1;
while(index % 7 != 0){
    r = [self rectForCellAtIndex:index] ;
    if ([marks count] > 0) 
        [self drawTileInRect:r day:i mark:[[marks objectAtIndex:index] boolValue] font:font font2:font2];
    else
        [self drawTileInRect:r day:i mark:NO font:font font2:font2];
    i++;
    index++;
}

}

问题在于,现在磁贴(CGRects)是黑色的。 或它们后面的任何视图都是黑色的,坦率地说,我对Tapku的代码有些迷惑。 有谁知道为什么瓷砖是黑色的? 还是我应该在Tapku代码中的什么地方看? 我对Core Graphics不太熟悉,所以也许我缺少一些基本的/显而易见的东西。

注意:我还尝试过更改TKCalendarMonthView的tileBox(它是一个UIScrollView,似乎包含日历图块)的颜色,尽管它确实更改了颜色,但不会影响图块的背景颜色。

提前致谢! 如果有任何不清楚的地方,请告诉我。

您可以按照以下步骤透明放置日历图块

第1步

注释TKCalendarMonthView.m中的代码

+ (void) initialize{
    if (self == [TKCalendarMonthTiles class]){
        //tileImage = [UIImage imageWithContentsOfFile:TKBUNDLE(@"calendar/Month Calendar Date Tile.png")];
    } 
}

第2步

更改TKCalendarMonthView.m中的代码

添加一行代码[self.currentTile setBackgroundColor:[UIColor clearColor]];

[self.tileBox addSubview:self.currentTile];行之前[self.tileBox addSubview:self.currentTile];

在方法中- (void) _setupCurrentTileView:(NSDate*)date

所以你的代码看起来像

- (void) _setupCurrentTileView:(NSDate*)date{

    ....

    [self.currentTile setBackgroundColor:[UIColor clearColor]];
    [self.tileBox addSubview:self.currentTile];

    ....

}

最后,我将了解如何在日历视图中使背景颜色清晰。

更改代码如下。

TKCalendarMonthView.m中

(1)在下面的行中注释/删除。

+ (void) initialize
{
     if (self == [TKCalendarMonthTiles class])
     {
    //tileImage = [UIImage imageWithContentsOfFile:TKBUNDLE(@"calendar/Month Calendar Date Tile.png")];   COMMENT THIS LINE
     } 
}

(2)- (void) _setupCurrentTileView:(NSDate*)date方法中
添加[self.currentTile setBackgroundColor:[UIColor clearColor]]; 行如下

- (void) _setupCurrentTileView:(NSDate*)date{
if(self.currentTile) return;

NSDate *month = [date firstOfMonthWithTimeZone:self.timeZone];
NSArray *dates = [TKCalendarMonthTiles rangeOfDatesInMonthGrid:month startOnSunday:self.sunday timeZone:self.timeZone];
NSArray *data = [self.dataSource calendarMonthView:self marksFromDate:dates[0] toDate:[dates lastObject]];

self.currentTile = [[TKCalendarMonthTiles alloc] initWithMonth:month marks:data startDayOnSunday:self.sunday timeZone:self.timeZone];
[self.currentTile setTarget:self action:@selector(_tileSelectedWithData:)];

[self.currentTile setBackgroundColor:[UIColor clearColor]]; // ADD THIS LINE
[self.tileBox addSubview:self.currentTile];

self.monthYear.text = [date monthYearStringWithTimeZone:self.timeZone];
[self _updateSubviewFramesWithTile:self.currentTile];

}
