1,这种方法,拨打完电话回不到原来的应用,会停留在通讯录里,而且是直接拨打,不弹出提示
NSMutableString * str=[[ NSMutableString alloc ] initWithFormat : @"tel:%@" , @"400-xxx-xxxx" ];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:str]];
2,这种方法,打完电话后还会回到原来的程序,也会弹出提示,推荐这种
NSMutableString * str=[[NSMutableString alloc] initWithFormat:@"tel:%@",@"400-xxx-xxxx"];
UIWebView * webview = [[UIWebView alloc] init];
[webview loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:str]]];
[self.view addSubview:webview];
3,这种方法也会回去到原来的程序里(注意这里的telprompt),也会弹出提示
NSMutableString * str=[[ NSMutableString alloc ] initWithFormat : @"telprompt://%@" , @" 400-xxx-xxxx " ];
dispatch_async(dispatch_get_global_queue(0, 0), ^{
NSMutableString * str=[[ NSMutableString alloc ] initWithFormat : @"tel:%@" , @"400-xxx-xxxx" ];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:str]];
