首先,我想对本网站上所有有用的答案表示感谢。我大约六个月前开始编程,我学到的很多东西都是来自问题/答案。
我在iPhone项目中使用Tapku Library中的日历,并希望日历图块是透明的,以便我可以看到我的TKCalendarMonthView视图背后的视图。
我使用Benjamin Pearson的this tutorial代码实现了TKCalendarMonthView。
然后我删除了平铺图像并尝试了@Jacques的this answer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++;
}
}
问题是现在瓷砖(CGRects)是黑色的;或者直接在它们后面的任何视图都是黑色的,坦率地说,我在Tapku的代码中有点迷失。有谁知道为什么瓷砖是黑色的?或者我应该看看Tapku代码中的哪个位置?我对Core Graphics不是很熟悉,所以也许我错过了一些基本/明显的东西。
注意:我也尝试更改TKCalendarMonthView的tileBox(这是一个似乎包含日历图块的UIScrollView)的颜色,尽管它确实改变了颜色,但它并没有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。
答案 0 :(得分:3)
您可以按照以下步骤透明日历切片
<强>步骤1 强>
注释TKCalendarMonthView.m中的代码
+ (void) initialize{
if (self == [TKCalendarMonthTiles class]){
//tileImage = [UIImage imageWithContentsOfFile:TKBUNDLE(@"calendar/Month Calendar Date Tile.png")];
}
}
<强>步骤-2 强>
更改TKCalendarMonthView.m
中的代码添加代码行[self.currentTile setBackgroundColor:[UIColor clearColor]];
行[{1}}
之前 方法[self.tileBox addSubview:self.currentTile];
中的
所以你的代码看起来像
- (void) _setupCurrentTileView:(NSDate*)date
答案 1 :(得分:1)
最后,我了解如何在日历视图中清除背景颜色。
更改代码如下。
在 TKCalendarMonthView.m
(1)评论/删除以下行。
+ (void) initialize
{
if (self == [TKCalendarMonthTiles class])
{
//tileImage = [UIImage imageWithContentsOfFile:TKBUNDLE(@"calendar/Month Calendar Date Tile.png")]; COMMENT THIS LINE
}
}
(2)在 - (void) _setupCurrentTileView:(NSDate*)date
方法中添加 [self.currentTile setBackgroundColor:[UIColor clearColor]];
行,如下所示
- (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];
}
