不能通过编程方式拨打iphone

Question

我已经完成了这样的编程调用。

NSString *phoneNumber = [[self.arrCategory objectAtIndex:0]objectForKey:@"MOBILE"]; 

NSString *phoneURLString = [NSString stringWithFormat:@"tel:%@", phoneNumber]; 
NSURL *phoneURL = [NSURL URLWithString:phoneURLString]; 
[[UIApplication sharedApplication] openURL:phoneURL]; 

但我不能从iphone进行呼叫。什么是问题？

Answer 1

试试这个&检查：

NSString *phoneNumber = [[self.arrCategory objectAtIndex:0]objectForKey:@"MOBILE"]; 
    NSString *phoneURLString = [@"tel://" stringByAppendingString:phoneNumber]; 
    NSURL *phoneURL = [NSURL URLWithString:phoneURLString]; 
    [[UIApplication sharedApplication] openURL:phoneURL];

现在只是用你的代码替换此代码，可能是其发生是因为在PHONENO或电话网址空白的地方用所以它不是called..use这个代码..

NSString *phoneNumber = [[self.arrCategory objectAtIndex:0]objectForKey:@"MOBILE"]; 
    NSArray* telComponents = [phoneNumber componentsSeparatedByCharactersInSet: [NSCharacterSet whitespaceAndNewlineCharacterSet]]; 
    phoneNumber = [telComponents componentsJoinedByString: @""]; 

    NSString* urlString = [NSString stringWithFormat: @"tel:%@", phoneNumber]; 
    NSURL* telURL = [NSURL URLWithString: urlString]; 

    if ([[UIApplication sharedApplication] canOpenURL: telURL]) 
    { 
     [[UIApplication sharedApplication] openURL: telURL]; 
    } 
    else 
    { 
     UIAlertView* alert = [[UIAlertView alloc] initWithTitle: NSLocalizedString(@"Dialer Error", @"") 
                 message: [NSString stringWithFormat: NSLocalizedString(@"There was a problem dialing %@.", @""), phoneNumber] 
                 delegate: nil 
               cancelButtonTitle: NSLocalizedString(@"OK", @"") 
               otherButtonTitles: nil]; 
     [alert show]; 
     [alert release]; 
    } 

UPDATE：

尝试，这也...

#import "RegexKitLite.h" 

NSString * number = @"(555) 555-555 Office"; 
NSString * strippedNumber = [number stringByReplacingOccurrencesOfRegex:@"[^0-9]" withString:@""]; 

看到链接此代码iphone sdk - Remove all characters except for numbers 0-9 from a string

请尝试从这里我的示例代码，

请使用phoneNumber的字符串的电话号码istead。请让我知道它是否对你有用。我希望它能帮助你。谢谢。

试试这个：

UIWebView *callWebview = [[UIWebView alloc] initWithFrame:CGRectMake(0,0, 0, 0)]; 
[self.view addSubview:callWebview]; 
NSString *phoneNumber = [[self.arrCategory objectAtIndex:0]objectForKey:@"MOBILE"]; 
    NSString *phoneWithoutSpaces = [[NSString stringWithFormat:@"tel://%@", phoneNumber] stringByReplacingOccurrencesOfString:@" " withString:@""]; 
NSURL *telURL = [NSURL URLWithString:phoneWithoutSpaces]; 
[callWebview loadRequest:[NSURLRequest requestWithURL:telURL]]; 

这是为我工作。
