A. 調整濾鏡表單水平擺放的位置
1. 開啓 ViewController.m 檔案, 修改如下:
....
- (UITableView *)filterListTableView
{
if (_filterListTableView == nil) {
....
//@update: Tune UI
/*
_filterListTableView = [[UITableView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, kOverlayTableViewRowHeight) style:UITableViewStyleGrouped];
*/
//@update: Tune for Orientation
_filterListTableView = [[UITableView alloc] init];
}
return _filterListTableView;
}
....
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
//@update
// 設備垂直擺放
if (interfaceOrientation == UIDeviceOrientationPortrait)
{
//@update: Tune UI
[self.filterLensImageView setFrame:CGRectMake(20, 120, 280, 280)];
//@update: Tune for Orientation
self.filterListTableView.transform = CGAffineTransformMakeRotation(-M_PI * 2.0);
[self.filterListTableView setFrame:CGRectMake(0, 0, self.view.frame.size.width, kOverlayTableViewRowHeight)];
}
// 設備垂直 180 度擺放
else if (interfaceOrientation == UIDeviceOrientationPortraitUpsideDown) {
//@update: Tune UI
[self.filterLensImageView setFrame:CGRectMake(20, 120, 280, 280)];
//@update: Tune for Orientation
self.filterListTableView.transform = CGAffineTransformMakeRotation(-M_PI * 2.0);
[self.filterListTableView setFrame:CGRectMake(0, 0, self.view.frame.size.width, kOverlayTableViewRowHeight)];
}
// 設備水平向右擺放
else if (interfaceOrientation == UIDeviceOrientationLandscapeRight) {
//@update: Tune UI
[self.filterLensImageView setFrame:CGRectMake(120, 20, 280, 280)];
//@update: Tune for Orientation
self.filterListTableView.transform = CGAffineTransformMakeRotation(M_PI * 0.5);
[self.filterListTableView setFrame:CGRectMake(0, 0, kOverlayTableViewRowHeight, self.view.frame.size.width)];
}
// 設備水平向左擺放
else if (interfaceOrientation == UIDeviceOrientationLandscapeLeft) {
//@update: Tune UI
[self.filterLensImageView setFrame:CGRectMake(120, 20, 280, 280)];
//@update: Tune for Orientation
self.filterListTableView.transform = CGAffineTransformMakeRotation(M_PI * 0.5);
[self.filterListTableView setFrame:CGRectMake(0, 0, kOverlayTableViewRowHeight, self.view.frame.size.width)];
}
// 其它 (UIDeviceOrientationFaceUp, UIDeviceOrientationFaceDown, UIDeviceOrientationUnknown)
else {
//@update: Tune UI
[self.filterLensImageView setFrame:CGRectMake(120, 20, 280, 280)];
//@update: Tune for Orientation
self.filterListTableView.transform = CGAffineTransformMakeRotation(M_PI * 0.5);
[self.filterListTableView setFrame:CGRectMake(0, 0, self.view.frame.size.width, kOverlayTableViewRowHeight)];
}
return YES;
}
....

B. 調整濾鏡表單水平擺放的 FilterCell
1. 新增一個類別來放置 global 變數
a. Xcode > File > New > File...
> iOS > Cocoa Touch > Objective-C class > Next
Class: GlobalDataClass
Subclass of: NSObject> Next > Create
b. 開啓 GlobalDataClass.h 檔案, 修改如下:
#import <Foundation/Foundation.h>
@interface GlobalDataClass : NSObject
{
//@add: array for storage filterCells
NSMutableArray *filterCellArray;
}
//@add
@property (nonatomic, strong) NSMutableArray *filterCellArray;
//@add
+ (GlobalDataClass *)getInstance;
@end
c. 開啓 GlobalDataClass.m 檔案, 修改如下:
#import "GlobalDataClass.h"
@implementation GlobalDataClass
//@add
@synthesize filterCellArray = _filterCellArray;
//@add
+ (GlobalDataClass *)getInstance
{
static GlobalDataClass *instance = nil;
@synchronized(self)
{
if(!instance)
{
instance = [[GlobalDataClass alloc] init];
}
}
return instance;
}
@end
---------------------------------------------------------------------------
2. 開啓 HorizontalTableCell.h 檔案, 修改如下:
#import <UIKit/UIKit.h>
//@add
#import "ConstantDefined.h"
#import "FilterCell.h"
//@add
#import "GlobalDataClass.h"
....
---------------------------------------------------------------------------
3. 開啓 HorizontalTableCell.m 檔案, 修改如下:
....
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
....
//@title text: we don't need to load that, just read it from our array of filters.
cell.titleLabel.text = [currentFilter objectForKey:@"Title"];
//@add for storage filterCells
//
// 當沒有找到相同的 titleLabel.text 時, 才將新的 filterCell 存入 Array 裡.
GlobalDataClass *dataObj = [GlobalDataClass getInstance];
BOOL saveCell = YES;
for (FilterCell* filterCell in dataObj.filterCellArray) {
if ([filterCell.titleLabel.text isEqualToString:cell.titleLabel.text])
{
saveCell = NO;
break;
}
}
if (saveCell) {
[dataObj.filterCellArray addObject:cell];
}
NSLog(@"dataObj.filterCellArray.count = %d", dataObj.filterCellArray.count);
return cell;
}
....
(update: 2012/04/20)
備註:
1. 當找到相同的 titleLabel.text 時, 如果刪除舊的 filterCell, 程式在執行時,
於拖拉"濾鏡表單" 時會 crash 掉.
2. 如果一律將 filterCell 儲存起來, 程式在執行時, 於每次拖拉"濾鏡表單" 時,
都會將新產生的 filterCell (即使 titleLabel.text 名稱相同)存入 Array 裡.
---------------------------------------------------------------------------
4. 開啓 ViewController.h 檔案, 修改如下:
....
//@add
#import "Filter4CamHelper.h"
#import "ConstantDefined.h"
#import "HorizontalTableCell.h"
#import "GlobalDataClass.h"
....
---------------------------------------------------------------------------
5. 開啓 ViewController.m 檔案, 修改如下:
....
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
//@add
GlobalDataClass *dataObj = [GlobalDataClass getInstance];
CGFloat filterCellRotationAngle; // filterCell Rotation Angle
//@update
// 設備垂直擺放
if (interfaceOrientation == UIDeviceOrientationPortrait)
{
//[self.filterLensImageView setFrame:CGRectMake(20, 80, 280, 280)];
//@update: Tune UI
[self.filterLensImageView setFrame:CGRectMake(20, 120, 280, 280)];
//@update: Tune for Orientation
self.filterListTableView.transform = CGAffineTransformMakeRotation(-M_PI * 2.0);
[self.filterListTableView setFrame:CGRectMake(0, 0, self.view.frame.size.width, kOverlayTableViewRowHeight)];
//@add
filterCellRotationAngle = M_PI * 0.5;
}
// 設備垂直 180 度擺放
else if (interfaceOrientation == UIDeviceOrientationPortraitUpsideDown) {
//[self.filterLensImageView setFrame:CGRectMake(20, 80, 280, 280)];
//@update: Tune UI

self.filterListTableView.transform = CGAffineTransformMakeRotation(-M_PI * 2.0);
[self.filterListTableView setFrame:CGRectMake(0, 0, self.view.frame.size.width, kOverlayTableViewRowHeight)];

filterCellRotationAngle = M_PI * 0.5;
}
// 設備水平向右擺放
else if (interfaceOrientation == UIDeviceOrientationLandscapeRight) {

//@update: Tune for Orientation
self.filterListTableView.transform = CGAffineTransformMakeRotation(M_PI * 0.5);

//@update: Tune for Orientation
self.filterListTableView.transform = CGAffineTransformMakeRotation(M_PI * 0.5);
[self.filterListTableView setFrame:CGRectMake(0, 0, kOverlayTableViewRowHeight, self.view.frame.size.width)];
//@add
filterCellRotationAngle = 0.0;
}
// 其它 (UIDeviceOrientationFaceUp, UIDeviceOrientationFaceDown, UIDeviceOrientationUnknown)
else {
//[self.filterLensImageView setFrame:CGRectMake(80, 20, 280, 280)];

self.filterListTableView.transform = CGAffineTransformMakeRotation(M_PI * 0.5);
[self.filterListTableView setFrame:CGRectMake(0, 0, self.view.frame.size.width, kOverlayTableViewRowHeight)];
//@add
filterCellRotationAngle = M_PI * 0.5;
}
//@add
if (dataObj.filterCellArray.count > 0) {
for (FilterCell* filterCell in dataObj.filterCellArray) {
filterCell.transform = CGAffineTransformMakeRotation(filterCellRotationAngle);
}
}
return YES;
}
....
