我有一个名为'LoginViewController'的文件,需要从'RootViewController.m'文件中执行一个动作。我做了一个NSLog,它的功能,但实际的脚本不。来自不同班级的IBAction无法正常工作?
我也登录了我的LoginViewController中的#import "RootViewController.h"
。
LoginViewController
RootViewController *test = [[RootViewController alloc] init];
[NSThread detachNewThreadSelector:@selector(updateAlbumsAfterLogin) toTarget:test withObject:nil];
RootViewController的
- (void)updateAlbumsAfterLogin {
NSLog(@"Updating albums after login!");
// Set up loading box and show it
UIImage *imageLoop = [UIImage imageNamed:@"loading_box.png"];
imagefour = [[UIImageView alloc] initWithImage:imageLoop];
imagefour.frame = CGRectMake(100, 80, 116, 116);
[self.view addSubview:imagefour];
// Set up loading text and show it
myLabel = [[UILabel alloc] initWithFrame:CGRectMake(97, 60, 130, 100)];
myLabel.text = @"Loading...";
myLabel.textColor = [UIColor whiteColor];
myLabel.textAlignment = UITextAlignmentCenter;
myLabel.backgroundColor = [UIColor clearColor];
myLabel.font = [UIFont fontWithName:@"Helvetica" size: 16.0];
myLabel.numberOfLines = 0;
//[myLabel sizeToFit];
[self.view addSubview:myLabel];
// Set up spinner and show it
myIndicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
myIndicator.center = CGPointMake(158, 155);
myIndicator.hidesWhenStopped = YES;
[self.view addSubview:myIndicator];
[myIndicator startAnimating];
[NSThread detachNewThreadSelector:@selector(updateAlbums) toTarget:self withObject:nil];
//myTimer = [NSTimer scheduledTimerWithTimeInterval:10.0 target:self selector: @selector(updateAlbums) userInfo: nil repeats: YES];
}
在此先感谢, 库尔顿。

嗨,谢谢你的回复。我到底需要在每个文件中进行更改才能做到这一点?谢谢! – iosfreak 2011-03-05 03:47:25
我在这个其他StackOverflow线程中描述了类似的东西:http://stackoverflow.com/questions/5188725/array-out-of-bounds-and-slow-slow-app/5189025#5189025 – 2011-03-05 04:16:22
感谢您的链接,但是当实施它,它不适用。尽管顶部的活动指标停止,但内容不会刷新并且表格视图为空白。 – iosfreak 2011-03-05 04:44:03
