UIActionSheet添加UIPickerView.
?今天写了一个ActionSheet添加的UIPickerView的程序,搜索了很多的资料
- (void)configurePickersAndActionSheets { CGRect pickerFrame; if ((self.interfaceOrientation == UIInterfaceOrientationPortrait) || (self.interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown)) { pickerFrame = CGRectMake(0, 180, 0, 0); } else { pickerFrame = CGRectMake(0,180,480,200); } self.areaActionSheet = [[[UIActionSheet alloc] initWithTitle:@"Area" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:@"Use",NULL] autorelease]; self.areaPicker = [[[UIPickerView alloc] initWithFrame:pickerFrame] autorelease]; self.areaPicker.delegate = self; self.areaPicker.showsSelectionIndicator = YES; [self.areaActionSheet addSubview:areaPicker];}
上面的代码就是横屏和纵屏的大小设置
if ((self.interfaceOrientation == UIInterfaceOrientationLandscapeLeft) || (self.interfaceOrientation == UIInterfaceOrientationLandscapeRight)) { [actionSheet setBounds:CGRectMake(0, 0, 480, 480)]; } else { [actionSheet setBounds:CGRectMake(0, 0, 320, 618)]; }
此处用来设置actionsheet的大小具体的添加PickerView如下:UIActionSheet?*menu?=?[[UIActionSheet alloc]?initWithTitle:[currentData objectAtIndex:0]?delegate:selfcancelButtonTitle:@"Done"destructiveButtonTitle:@"Cancel"otherButtonTitles:nil];?
UIPickerView?[[UIPickerView ? alloc]initWithFrame(0,40,480,200)];
pickerView.delegate?=?self;pickerView.showsSelectionIndicator?=?YES; ? ??
[menu addSubview];[menu showInView];[menu setBounds(0,0,480, 320)];
[pickerView release];[menu release];
?
OK这个就完成了ActionSheet的操作,可能你还会有一个问题就是在UIPickerView如何设置显示下拉框的
字体大小,即改变显示数组中的字体大小:?
需要重写实现如下方法?
- (viewForRow:(? forComponent:( ? reusingView:(
pickerLabel = [[pickerLabel.?
pickerLabel.?? ?}
?? ? ??pickerLabel.?? }
?? pickerLabel.}
return?0;
}
?
?
这样就解决字体大小的问题了.?
