Ios 在drawRect中的图形项目上添加触摸事件
我正在制作一个日历应用程序。现在我像这样在屏幕上画出我的约会Ios 在drawRect中的图形项目上添加触摸事件,ios,iphone,objective-c,drawrect,Ios,Iphone,Objective C,Drawrect,我正在制作一个日历应用程序。现在我像这样在屏幕上画出我的约会 if (boolMark) { UIColor *blueColorMark = [UIColor colorWithRed:0 green:.62 blue:.984 alpha:0.5]; appointmentRect.origin.x += 5; appointmentRect.size.width -= 10; NSArray *appointments = [
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,显示一个详细视图,其中包含有关该约会的更多信息
我现在的问题是,当用户点击某个约会(某个重叠图像)时,如何设置操作
有什么帮助吗
亲切问候几件事:
如果您将约会解析为一个模型类Appointment
,则会更容易。
在绘制每个约会之前,先计算每个约会视图的rect,然后可以将该数据存储在一组字典中,以备以后使用,类似这样的方法
@[@{@"appointmentKey" : appointmentObject1, @"frameKey" : [NSValue valueWithCGRect:calculatedRect1]},
@{@"appointmentKey" : appointmentObject2, @"frameKey" : [NSValue valueWithCGRect:calculatedRect2]}];
- 稍后,您将使用此选项绘制并找到正确的约会
- 制作一个方法
,它迭代上层数组中的所有字典并检查Appointment*appointmentForPoint:(CGPoint)
;如果为true,则返回与该词典关联的约会CGRectContainsPoint(rect,point)
- 将轻触手势识别器添加到视图中,并调用
以获得正确的约会李>appointmentForPoint:
