我正在制作日历应用。现在我在屏幕上画这样的约会。
if (boolMark) {
UIColor *blueColorMark = [UIColor colorWithRed:0 green:.62 blue:.984 alpha:0.5];
appointmentRect.origin.x += 5;
appointmentRect.size.width -= 10;
NSArray *appointments = [[mark valueForKey:@"appointments"] mutableCopy];
float lblHeight = appointmentRect.origin.y - tileHeightAdjustment + 20;
for (NSDictionary *appointment in appointments){
UIImage *overlayImage=[self imageWithColor:blueColorMark];
NSString *strTitle = [NSString stringWithFormat:@"%@",[appointment valueForKey:@"app_label"]];
if (forIpad) {
NSLog(@"AppointmentRect Y = %f",lblHeight);
appointmentRect.origin.y = lblHeight;
}
else
{
appointmentRect.origin.y -= 6;
}
appointmentRect.size.height = [self calculateHeight:strTitle andWidth:appointmentRect.size.width];
lblHeight += appointmentRect.size.height + 5;
[overlayImage drawInRect:appointmentRect];
UIFont *f3 =[UIFont fontWithName:@"MyriadPro-Regular" size:10];
[strTitle drawInRect: appointmentRect
withFont: f3
lineBreakMode:NSLineBreakByWordWrapping
alignment: NSTextAlignmentCenter];
}
}
现在,我希望当用户触摸某个约会时,会显示一个detailView,其中包含有关约会的更多信息。
我现在的问题是,当用户点击某个约会(某个overlayImage)时,如何设置动作?
任何帮助?
亲切的问候

有几件事:
如果您将约会解析为模型类Appointment
,则会更容易。
在绘制每个约会之前,计算每个约会视图的rect,然后你可以将这些数据存储在一个词典数组中以供日后使用,如下所示
@[@{@"appointmentKey" : appointmentObject1, @"frameKey" : [NSValue valueWithCGRect:calculatedRect1]},
@{@"appointmentKey" : appointmentObject2, @"frameKey" : [NSValue valueWithCGRect:calculatedRect2]}];
Appointment* appointmentForPoint:(CGPoint point)
,它迭代上层数组中的所有字典并检查CGRectContainsPoint(rect, point)
;如果为true,则返回与该词典相关联的约会。appointmentForPoint:
以获得正确的约会。
