我已为我添加的每个标签设置了一个基于UITabBr的应用程序,其中包含许多UIViewControllers(5) 现在我遇到了为每个标签添加TableView的问题,正如我在此指出的那样UITableView in each tab 但没有人有解决方案,所以我想到了它并尝试了很多方法 现在的观点是:当用户触摸标签时,首先在UIViewController中调用哪个方法? (viewDidLoad和viewWillAppear不起作用)
有一个特定的生命周期吗?
这是正常代码,当您单击选项卡
时,控制台中不会显示任何内容#
import "MusicView.h"
@implementation MusicView
@synthesize tv;
// Customize the number of sections in the table view.
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
// Customize the number of rows in the table view.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return 10;
}
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
//cell.textLabel.text = [elements objectAtIndex:indexPath.row];
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
}
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
NSLog(@"initWithNibName works");
}
return self;
}
- (void)dealloc
{
[super dealloc];
}
- (void)didReceiveMemoryWarning
{
// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];
// Release any cached data, images, etc that aren't in use.
}
#pragma mark - View lifecycle
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
NSLog(@"viewDidLoad works");
}
- (void)viewDidUnload
{
[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

您是否已将自己设置为数据源和委托以及子类UITableViewController,并在各个选项卡视图控制器中订阅数据源和委托协议?
答案 1 :(得分:0)
There is too much information you haven't provided.
我们不知道它是什么子类,我们对委托/数据源方法一无所知。
