我有一个UIWebView工作正常.代表正在工作.当我打开一个URL,事件shouldStartLoadWithRequest和webViewDidFinishLoad被解雇.

但是,例如,当我点击Google搜索结果时,只会shouldStartLoadWithRequest被触发,并且webViewDidFinishLoad永远不会被调用.

这会导致问题,因为如果我打开"loading ..."指示器shouldStartLoadWithRequest,在这些情况下,即使页面正确加载后指示器仍然保持不变.

知道为什么会这样吗？

我的电话号码格式是(987)786-5645.

- (BOOL)validatePhoneNumberWithString:(NSString*)phone
{
    NSString *pNRegex = @"[(0-9)]{3}+\\ +\\[0-9-]{3}+\\[0-9]{4}";
    NSPredicate *PNTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", pNRegex];
    return [PNTest evaluateWithObject:phone];
}

我正在使用上面的代码.

这应该是什么样的正则规则？我能够弄清楚数字和括号.

关闭括号后我应该用什么来检测空格？

我有下一个代码:

@implementation SplashViewVC

- (void)viewDidLoad
{
    [super viewDidLoad];
    self.splashView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"Default.png"]];
    self.activityIndicator.originY = 355.f;
    [[NSNotificationCenter defaultCenter] addObserverForName:NCDownloadComplete object:nil queue:[NSOperationQueue mainQueue] usingBlock:^(NSNotification *n){
        NSInteger errorCode = [n.userInfo[@"errorCode"] integerValue];        
        [self.activityIndicator stopAnimating];
        if (errorCode == ERROR_CODE_NO_CONNECTION) {
            UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error" message:@"Some problem with server" delegate:self cancelButtonTitle:@"try again" otherButtonTitles:nil];
            [alertView show];
        } else if (errorCode == 0) {
            [self dismissViewControllerAnimated:YES completion:nil];
        }
    }];
    [self downloadData];
}

- (void)downloadData
{
    [self.activityIndicator startAnimating];
    [[Server sharedServer] getMovieData];
}

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex …

我是第一次使用故事板.

每当我第一次运行构建时,我的应用程序都会崩溃,它从服务器下载所有数据.UIViewController-w6Q-ra-j06尽管在我的项目中没有这个名字的文件,但它显示我的错误.

任何指针或帮助将不胜感激.

发送Apple推送通知时遇到问题.

当我只向两台设备发送消息时,一切正常.但是当我向数据库中的所有设备发送消息时,并不是所有的推送消息都被传递,但我没有得到任何设备的错误.发送还可以!

当我将消息发布到所有设备时,其中一个在第一次测试中获取消息的设备没有收到消息.

发送程序正在运行,因为我在第一次测试时在手机上收到一条消息,当我发送到所有设备时它也能正常工作.可以有任何其他问题导致这个问题吗？或者这是Apple的bug /问题.

我不知道问题是什么.有人也有这个问题吗？

我正在为我的大学开发导航系统作为某种研究活动.我正在使用SVGKit来显示平面图.现在我需要提供用户定位服务以进行导航和跟踪.所以这是我的问题:

问:为什么Redpin iPhone客户端不符合iPhone SDK协议？答:Apple不提供检索WiFi数据的公共API.为了让iPhone客户端正常工作,我们不得不使用私有API,iPhone SDK协议不允许这样做.

谢谢大家,也许你可以为我提供更好的解决方案.提前致谢.

我一直坚持这个问题一段时间了.问题是我需要输出"---页面结束---"以保留每页的剩余空白.

截图: 页面内容是动态生成的.

我想出了这个逻辑:

1. 每页的getRemainingWidth()
2. 然后从起点(下边距减去RemainingWidth)到下边距找到水平和垂直中心
3. 并输出"页面结束"

有人解决过这个吗？

谢谢!

在我的项目中,我必须将a的长度限制UITextField为6个字符.这工作绝对正常.一旦我结束编辑并再次开始编辑,我点击退格我的应用程序崩溃.

这是代码:

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string 
{   
    NSUInteger newLength = [txtLicense.text length] + [strNumber length] - range.length;
    return (newLength > 6) ? NO : YES;
}

默认文本的颜色是什么UIButton？我正在尝试在一些表视图单元格中重新创建它但没有运气.我最接近的是:

[UIColor colorWithRed:0/255.0 green:51.0/255.0 blue:102.0/255.0 alpha:1];

是否在任何地方记录了颜色,字体大小和样式？

我通过解析"fmt stream map"来获取Stream URL,
