簡單的問題(是啊,對!)。我想在我的iPad項目的UISplitViewController的詳細信息頁面上添加一個「NEXT」按鈕。如果點擊,這將是另一種前進到頁面列表中下一頁的方式。作爲獎勵,我想突出顯示與您登陸的新視圖相對應的根視圖中的正確行。添加一個下一個按鈕到iPad UISplitViewControl
任何關於去哪兒的一般指導和建議都會非常棒!
更新:感謝下面的Anna的建議,這裏是我用來將所有這一切拉到一起的代碼。它工作很棒。謝謝安娜。
在明細頁面,包括這個:
- (IBAction)goToNext{
NSLog(@"Going to Next from Welcome");
[[NSNotificationCenter defaultCenter]
postNotificationName:@"NextPageRequested" object:nil];
}
在RootViewController的頁面我所做的:
- (void)viewDidLoad {
[super viewDidLoad];
[[NSNotificationCenter defaultCenter]
addObserver:self selector:@selector(moveOnToNextPage:)
name:@"NextPageRequested" object:nil];
}
最後後來在RootViewController的:
#pragma mark -
#pragma mark The NEXT Button
// This is the Code used for the Big NEXT button. basically a Notification Center listener is set up in the view did load and when triggered by any of the buttons, this
// function is called. Here, I do 3 things: 1. advance the highlighted cell of the master table view. 2. call the didSelectRowAtIndexPath function of the table to
// advance to the next page. and 3. Exchange the "dash" icon with the "check" icon.
-(void)moveOnToNextPage:(NSNotification*)notifications {
NSIndexPath* selection = [self.tableView indexPathForSelectedRow]; // grab the row path of the currently highlighted item
// Change the icon in the current row:
NSString *checkImage = [[NSBundle mainBundle] pathForResource:@"checkGreen" ofType:@"png"];
UIImage *checkMark = [[[UIImage alloc] initWithContentsOfFile:checkImage] autorelease]; // Grab the checkmark image.
if (selection) {
NSLog(@"not nil");
UITableViewCell *cell1 = [self.tableView cellForRowAtIndexPath:[self.tableView indexPathForSelectedRow]];
// cell1.accessoryType = UITableViewCellAccessoryCheckmark; // this is yet another way to add the checkmar, but for now, I will use Mine.
cell1.imageView.image = checkMark; // now set the icon
} else {
NSLog(@"must be nil");
NSUInteger indexArrBlank[] = {0,0}; // now throw this back into the integer set
NSIndexPath *blankSet = [NSIndexPath indexPathWithIndexes:indexArrBlank length:2]; // create a new index path
UITableViewCell *cell0 = [self.tableView cellForRowAtIndexPath:blankSet];
// cell1.accessoryType = UITableViewCellAccessoryCheckmark; // this is yet another way to add the checkmar, but for now, I will use Mine.
cell0.imageView.image = checkMark; // now set the icon
}
// Highlight the new Row
int nextSelection = selection.row +1; // grab the int value of the row (cuz it actually has both the section and the row {section, row}) and add 1
NSUInteger indexArr[] = {0,nextSelection}; // now throw this back into the integer set
NSIndexPath *indexSet = [NSIndexPath indexPathWithIndexes:indexArr length:2]; // create a new index path
[self.tableView selectRowAtIndexPath:indexSet animated:YES scrollPosition:UITableViewScrollPositionTop]; // tell the table to highlight the new row
// Move to the new View
UITableView *newTableView = self.tableView; // create a pointer to a new table View
[self tableView:newTableView didSelectRowAtIndexPath:indexSet]; // call the didSelectRowAtIndexPath function
//[newTableView autorelease]; //let the new tableView go. ok. this crashes it, so no releasing for now.

安娜,我認爲這是我正在尋找的方向。我會嘗試遵循你的建議,看看會發生什麼。 – 2011-04-27 04:03:22
