與其他iOS應用程序通信

Question

我的工作是基於一個應用程序ChattAr-IOS從項目QuickBlox中，他們有一個UIWebViewController由於我不能與其他應用進行溝通，每次我試圖打開Waze的使用下面的代碼應用形成我的應用程序：

 - (void) navigateToLatitude:(double)latitude
              longitude:(double)longitude
{
  if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"waze://"]]) {
    //Waze is installed. Launch Waze and start navigation
    NSString *urlStr = [NSString stringWithFormat:@"waze://?ll=%f,%f&navigate=yes", latitude, longitude];
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlStr]];
} else {
    //Waze is not installed. Launch AppStore to install Waze app
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://itunes.apple.com/us/app/id323229106"]];
    }
}

它導航到該UIWebView 。 該項目中有一個ChatARApplication類，可能是導致問題的原因。

ChattARApplication.h

#import <UIKit/UIKit.h>

@interface ChattARApplication : UIApplication

@end

ChattARApplication.m

#import "ChattARApplication.h"
#import "WebViewController.h"
#import "AppDelegate.h"

@implementation ChattARApplication

 -(BOOL)openURL:(NSURL *)url{
    UITabBarController *tabBarControlelr = ((AppDelegate *)self.delegate).tabBarController;
if(tabBarControlelr.selectedIndex != 1){
    return [super openURL:url];
    }

    // handle chat messages' links
    WebViewController *webViewControleler = [[WebViewController alloc] init];
    webViewControleler.urlAdress = [url absoluteString];
    webViewControleler.webView.scalesPageToFit = YES;
    UINavigationController *chatViewController = [tabBarControlelr.viewControllers objectAtIndex:1];
    [chatViewController pushViewController:webViewControleler animated:YES];
    [webViewControleler autorelease];

    return NO;
}

@end

Answer 1

解決了問題

如此少的代碼和平就可以解決問題

 if ([[url scheme] isEqualToString:@"waze"]) {
    return [super openURL:url];
}

在-(BOOL)openURL:(NSURL *)url

Answer 2

主目錄

int main(int argc, char *argv[]){
    @autoreleasepool {
        return UIApplicationMain(argc, argv, NSStringFromClass([ChattARApplication class]), NSStringFromClass([AppDelegate class]));
    }
}

我認為這是問題所在。如果要保留應用程序設置，可以在-(BOOL)openURL:(NSURL *)url;放置一些代碼-(BOOL)openURL:(NSURL *)url;

希望能幫到你~~
