Được rồi, sau một thời gian dài vật lộn với chế độ xem ngu ngốc trong iOS 4, tôi đã quyết định thay đổi điều khiển của mình thành bảng đơn giản: đây là mã:
ComboBoxView.m = which is actually looks more like pickerview.
//
// ComboBoxView.m
// iTrophy
//
// Created by Gal Blank on 8/18/10.
//
#import "ComboBoxView.h"
#import "AwardsStruct.h"
@implementation ComboBoxView
@synthesize displayedObjects;
#pragma mark -
#pragma mark Initialization
/*
- (id)initWithStyle:(UITableViewStyle)style {
// Override initWithStyle: if you create the controller programmatically and want to perform customization that is not appropriate for viewDidLoad.
if ((self = [super initWithStyle:style])) {
}
return self;
}
*/
#pragma mark -
#pragma mark View lifecycle
/*
- (void)viewDidLoad {
[super viewDidLoad];
// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
// self.navigationItem.rightBarButtonItem = self.editButtonItem;
}
*/
/*
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
}
*/
/*
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
}
*/
/*
- (void)viewWillDisappear:(BOOL)animated {
[super viewWillDisappear:animated];
}
*/
/*
- (void)viewDidDisappear:(BOOL)animated {
[super viewDidDisappear:animated];
}
*/
/*
// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
*/
#pragma mark -
#pragma mark Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
// Return the number of rows in the section.
self.tableView.separatorStyle = UITableViewCellSeparatorStyleSingleLine;
return [[self displayedObjects] count];
}
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *MyIdentifier = [NSString stringWithFormat:@"MyIdentifier %i", indexPath.row];
UITableViewCell *cell = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:MyIdentifier] autorelease];
//cell.contentView.frame = CGRectMake(0, 0, 230.0,16);
UILabel *label = [[[UILabel alloc] initWithFrame:CGRectMake(0, 5, 230.0,19)] autorelease];
VivatAwardsStruct *vType = [displayedObjects objectAtIndex:indexPath.row];
NSString *section = [vType awardType];
label.tag = 1;
label.font = [UIFont systemFontOfSize:17.0];
label.text = section;
label.textAlignment = UITextAlignmentCenter;
label.baselineAdjustment = UIBaselineAdjustmentAlignCenters;
label.adjustsFontSizeToFitWidth=YES;
label.textColor = [UIColor blackColor];
//label.autoresizingMask = UIViewAutoresizingFlexibleHeight;
[cell.contentView addSubview:label];
//UIImage *image = nil;
label.backgroundColor = [UIColor whiteColor];
//image = [awards awardImage];
//image = [image imageScaledToSize:CGSizeMake(32.0, 32.0)];
//[cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator];
//UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
//cell.accessoryView = imageView;
//[imageView release];
}
return cell;
}
/*
// Override to support conditional editing of the table view.
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
// Return NO if you do not want the specified item to be editable.
return YES;
}
*/
/*
// Override to support editing the table view.
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
if (editingStyle == UITableViewCellEditingStyleDelete) {
// Delete the row from the data source
[tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:YES];
}
else if (editingStyle == UITableViewCellEditingStyleInsert) {
// Create a new instance of the appropriate class, insert it into the array, and add a new row to the table view
}
}
*/
/*
// Override to support rearranging the table view.
- (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)fromIndexPath toIndexPath:(NSIndexPath *)toIndexPath {
}
*/
/*
// Override to support conditional rearranging of the table view.
- (BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath {
// Return NO if you do not want the item to be re-orderable.
return YES;
}
*/
#pragma mark -
#pragma mark Table view delegate
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
// Navigation logic may go here. Create and push another view controller.
/*
<#DetailViewController#> *detailViewController = [[<#DetailViewController#> alloc] initWithNibName:@"<#Nib name#>" bundle:nil];
// ...
// Pass the selected object to the new view controller.
[self.navigationController pushViewController:detailViewController animated:YES];
[detailViewController release];
*/
}
#pragma mark -
#pragma mark Memory management
- (void)didReceiveMemoryWarning {
// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];
// Relinquish ownership any cached data, images, etc that aren't in use.
}
- (void)viewDidUnload {
// Relinquish ownership of anything that can be recreated in viewDidLoad or on demand.
// For example: self.myOutlet = nil;
}
- (void)dealloc {
[super dealloc];
}
@end
Đây là tệp .h cho điều đó:
//
// ComboBoxView.h
// iTrophy
//
// Created by Gal Blank on 8/18/10.
//
#import <UIKit/UIKit.h>
@interface ComboBoxView : UITableViewController {
NSMutableArray *displayedObjects;
}
@property (nonatomic, retain) NSMutableArray *displayedObjects;
@end
now, in the ViewController where I had Apple UIPickerView I replaced with my own ComboBox view and made it size what ever I wish.
ComboBoxView *mypickerholder = [[ComboBoxView alloc] init];
[mypickerholder.view setFrame:CGRectMake(50, 220, 230, 80)];
[mypickerholder setDisplayedObjects:awardTypesArray];
thế là xong, bây giờ việc duy nhất còn lại là tạo một biến thành viên trong dạng xem hộp kết hợp sẽ giữ lựa chọn hàng hiện tại và chúng ta đã sẵn sàng.
Chúc mọi người vui vẻ.
