iOS 撥打電話三種方式總結

1,這種方法,撥打完電話回不到原來的應用,會停留在通訊錄裡,而且是直接撥打,不彈出提示
NSMutableString * str=[[NSMutableString alloc] initWithFormat:@”tel:%@”,@”186xxxx6979”];
// NSLog(@”str======%@”,str);
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:str]];
2,這種方法,打完電話後還會回到原來的程式,也會彈出提示,推薦這種
NSMutableString * str=[[NSMutableString alloc] initWithFormat:@”tel:%@”,@”186xxxx6979”];
UIWebView * callWebview = [[UIWebView alloc] init];
[callWebview loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:str]]];
[self.view addSubview:callWebview];
[callWebview release];
[str release];
3,這種方法也會回去到原來的程式裡(注意這裡的telprompt),也會彈出提示
NSMutableString * str=[[NSMutableString alloc] initWithFormat:@”telprompt://%@”,@”186xxxx6979”];
// NSLog(@”str======%@”,str);
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:str]]
