openURL的使用方法：

CODE:

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:appString]];

 

除此之外，还可以自己定义URL，方法如下：

CODE:

打开info.plist，添加一项URL types
展开URL types，再展开Item1，将Item1下的URL identifier修改为URL Scheme
展开URL Scheme，将Item1的内容修改为myapp
其他程序可通过myapp://访问此自定义URL

 

 

+ (void)alert:(NSString *)msg

{

    UIAlertView *alertView = [[[UIAlertView alloc] initWithTitle:msg message:@"" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil] autorelease];

    [alertView showWithBackground];

}

  

+ (NSString*) cleanPhoneNumber:(NSString*)phoneNumber

{

    NSString* number = [NSString stringWithString:phoneNumber];

    NSString* number1 = [[[number stringByReplacingOccurrencesOfString:@" " withString:@""]

                          //                        stringByReplacingOccurrencesOfString:@"-" withString:@""]

                          stringByReplacingOccurrencesOfString:@"(" withString:@""] 

                         stringByReplacingOccurrencesOfString:@")" withString:@""];

      

    return number1;    

}

  

+ (void) makeCall:(NSString *)phoneNumber

{

    

NSString* numberAfterClear = [self cleanPhoneNumber:phoneNumber];    

      

    NSURL *phoneNumberURL = [NSURL URLWithString:[NSString stringWithFormat:@"tel:%@", numberAfterClear]];

    NSLog(@"make call, URL=%@", phoneNumberURL);

      

    [[UIApplication sharedApplication] openURL:phoneNumberURL];    

}

  

拔打前会有提示，并且拔打结束后返回到自己的应用程序

[[UIApplicationsharedApplication] openURL:[NSURLURLWithString:@"telprompt://10086"]];

 

直接拔打，不会提示，拔打结束后停留在电话应用上

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://10086"]];

 

 

+ (void) sendSms:(NSString *)phoneNumber

{

      

    NSString* numberAfterClear = [self cleanPhoneNumber:phoneNumber];

    NSLog(@"send sms, URL=%@", phoneNumberURL);

    [[UIApplication sharedApplication] openURL:phoneNumberURL];    

}

  

+ (void) sendEmail:(NSString *)phoneNumber

{

    NSURL *phoneNumberURL = [NSURL URLWithString:[NSString stringWithFormat:@"mailto:%@", phoneNumber]];

    NSLog(@"send sms, URL=%@", phoneNumberURL);

    [[UIApplication sharedApplication] openURL:phoneNumberURL];    

}

    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:str]];
