无法在iPhone中以编程方式拨打电话 [英] can't dial call from programmatically in iphone

问题描述

我已经以编程方式完成了这样的通话.

I have done call programmatically like this.

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

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

但是我无法通过iphone拨打电话.有什么问题吗?

but I can't do call from iphone. What is the problem?

推荐答案

现在仅将这段代码替换为您的代码，可能是由于在phoneno或phone url中使用空格而不使用它而导致的.

now just replace this code with your code , may be its occurred because in phoneno or phone url somewhere whitespace is used so its not called..use this code..

    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];
    }

更新:

也尝试一下...

#import "RegexKitLite.h"

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