本文主要是介绍iOS-应用间通信之自定义URL Schemes,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
一、URL Schemes知识的了解
二、调用自己开发的应用
CFBundleURLName(URL Identifier) A string containing the abstract name of the URL scheme. To ensure uniqueness, it is recommended that you specify a reverse-DNS style of identifier, for example, com.acme.myscheme.The string you specify is also used as a key in your app’s InfoPlist.strings file. The value of the key is the human-readable scheme name.
CFBundleURLSchemes(URL Schemes) An array of strings containing the URL scheme names—for example, http, mailto, tel, and sms.
可以设置多个(URL Schemes),设置成功后如下:
调用方的部分代码如下:
- - (void)viewDidLoad
- {
- [super viewDidLoad];
- // Do any additional setup after loading the view.
- CGRect rectTextView= CGRectMake(10.0f, 30.0f, 300.0f, 100.0f);
- self.textView = [[UITextView alloc] initWithFrame:rectTextView];
- [self.textView.layer setBorderColor:[UIColor lightGrayColor].CGColor];
- [self.textView.layer setBorderWidth:0.5f];
- [self.textView setText:@"username=WT&password=123456&callback=invoking"];
- [self.view addSubview:self.textView];
- CGRect rect = CGRectMake(10.0f, 150.0f, 300.0f, 40.0f);
- UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
- button.frame = rect;
- [button setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
- [button setTitle:@"Login" forState:UIControlStateNormal];
- [button setBackgroundColor:[UIColor blueColor]];
- [button addTarget:self action:@selector(handle:) forControlEvents:UIControlEventTouchUpInside];
- [button.layer setMasksToBounds:YES];
- [button.layer setCornerRadius:5.0f];
- [self.view addSubview:button];
- }
- - (void)handle:(id)sender
- {
- NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:
- @"invoked://com.hello/path?%@", self.textView.text]];
- if ([[UIApplication sharedApplication] canOpenURL:url]) {
- [[UIApplication sharedApplication] openURL:url];
- } else {
- UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"message"
- message:[NSString stringWithFormat:@"%@", url]
- delegate:self cancelButtonTitle:@"确定"
- otherButtonTitles:nil, nil nil];
- [alertView show];
- }
- }
被调用方的接收代码:
- - (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
- {
- NSLog(@"%@", url);
- if ([[url scheme] isEqualToString:@"invoked"]) {
- if ([[url host] isEqualToString:@"com.hello"]) {
- NSString *query = [url query];
- NSArray *array = [query componentsSeparatedByString:@"&"];
- NSMutableDictionary *dic = [NSMutableDictionary dictionaryWithCapacity:10];
- for (NSString *item in array) {
- NSArray *valueArray = [item componentsSeparatedByString:@"="];
- [dic setValue:[valueArray objectAtIndex:1] forKey:[valueArray objectAtIndex:0]];
- }
- [self application:application didFinishLaunchingWithOptions:dic];
- }
- return YES;
- }
- return NO;
- }
同样,可以在传入参数中设置一些预留字段,以便以后扩展,要实现再能够回调回去,就可以加一个callback字段,如:callback=myapp 后面跟上自己应用的URL Scheme,再将执行完成的结果返回回去。代码处理和被调用方大致相同。
