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"]];
