我已經在Xcode 4.2中創建了一個xib文件,我正在尋找它到選項卡式應用程序,但我一直在嘗試,並且我對Xcode有點新,編碼這樣就是爲什麼我需要你的幫助我有我的代碼在下面,但是有一些小錯誤,但是我希望你能幫助我的是可能得到一個選項卡式應用程序......並告訴我該怎麼做。繼承人一個視頻給你看看,如果我沒有解釋它正確的情況下(這是我的視頻我只是爲這個問題http://www.youtube.com/watch?v=e7R5_kGClM0希望視頻幫助,但更重要的是你可以幫助我在xib文件中使用UIpickerview
有.H但在這個
#import <UIKit/UIKit.h>
@interface myview : UIViewController <UITableViewDelegate, UITableViewDataSource, UIPickerViewDelegate, UIPickerViewDataSource>
@property (strong, nonatomic) IBOutlet UITableView* tableView;
@property (strong, nonatomic) IBOutlet UIPickerView* pickerView;
@property (strong, nonatomic) NSMutableArray* tableData;
@property (strong, nonatomic) NSMutableArray* pickerData;
@end
沒有錯誤這是.M但我會打破它
#import "myview.h"
@implementation myview
@synthesize tableView, pickerView, tableData, pickerData;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
這是 - (無效)viewDidLoad中];等等。
- (void)viewDidUnload
{
[super viewDidUnload];
tableView.delegate = self;
tableView.dataSource = self;
pickerView.delegate = self;
pickerView.dataSource = self;
tableData = [[NSMutableArray alloc] init]; // table starts empty
pickerData = [[NSMutableArray alloc] initWithObjects:@"1", @"2", @"3", @"4", @"5", nil]; // picker starts with values 1, 2, 3, 4, 5
[tableView reloadData];
[pickerView reloadAllComponents]; // Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (布爾)
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
- (NSInteger)numberOfSectionsInTableView:(UITableView*)tableView {
//The number of sections in UITableView
return 1;
}
- (NSInteger)tableView:(UITableView*)tableView numberOfRowsInSection:(NSInteger)section {
// The number of rows in the UITableView
return [tableData count];
}
- (UITableViewCell*)tableView:(UITableView*)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *cellIdentifier = @"cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil) {
cell = [ [UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:cellIdentifier];
}
// Set the table cell text to the appropriate value in tableDate
cell.textLabel.text = [tableData objectAtIndex:indexPath.row];
return cell;
}
- (void)tableView:(UITableView*)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
// Whatever happens when you select a table view row.
}
- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView
{
// The number of sections in the UIPickerView
return 1;
}
- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component
{
// The number of rows in the UIPickerView
return [pickerData count];
}
- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
{
// The data for each row in the UIPickerView
return [pickerData objectAtIndex:row];
}
- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
// whatever you want to happen when a row is selected.
// here I am assuming you want to remove from the picker and add to the table on selection
[tableData addObject:[pickerData objectAtIndex:row]];
[pickerData removeObjectAtIndex:row];
[tableView reloadData];
[pickerView reloadAllComponents];
}
@end
這裏是錯誤的代碼中有兩個
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
^^^^^^^^^^^^^^^^^
**Local declaration of 'tableView hides instance variable**
二錯誤
[pickerView reloadAllComponents];
^^^^^^^^^^^^^^
Local declaration of 'pickerView hides instance variable
非常感謝我希望在這裏由你很快!!!
謝謝男人:)! – 2012-02-23 09:46:15
