以編程方式將uibutton添加到詳細視圖

Question

如何添加一個可以顯示電話號碼的uibutton並呼叫該號碼，以自動方式從每個表視圖單元的數組中加載數據

Answer 1

蘋果文檔告訴您使用tel：// url方案。 而這個線程

舉一個很好的例子：

NSString *phoneStr = [NSString stringWithFormat:@"tel:%@",[self.contactDetails objectForKey:@"phone"]];
NSString *escaped = [phoneStr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:escaped]];

Answer 2

在每個單元格中放置一個按鈕，並將文本設置為數組中的電話號碼。 然后，在按鈕的按下選擇器上，調用URL tel:<PHONE NUMBER>:

- (UITableViewCell *)cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    ...
    UIButton *callButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    [callButton addTarget:self selector:@selector(callButtonPressed:)];
    [callButton setTitle:@"<PHONE NUMBER>"];
    [cell addSubview:callButton];
}

- (void)callButtonPressed:(id)sender {
    NSString *phoneURLAsString = [NSString stringWithFormat:@"tel:%@", sender.currentTitle];
    NSString *escapedPhoneURLAsString = [phoneURLAsString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:escapedPhoneURLAsString]];
}
