我有一个旧的
Xcode项目,针对iOS 6及更高版本.我最近在Xcode 6中打开了它,并在iOS 8的iPhone 6模拟器中运行.当我尝试这个动作
UIAlertView* dialog = [[UIAlertView alloc] initWithTitle:@"Enter Folder Name"
message:@"Keep it short and sweet"
delegate:self
cancelButtonTitle:@"Cancel"
otherButtonTitles:@"OK",nil];
dialog.alertViewStyle = UIAlertViewStylePlainTextInput;
dialog.tag = 400;
[dialog show];
我得到一个弹出窗口,但当我点击文本字段,没有键盘出现.我googled和阅读,我需要使用UIAlertController代替.因为我需要支持iOS 6,7版本,所以我改变了我的代码.
if ([UIAlertController class])
{
// use UIAlertController
UIAlertController *alert= [UIAlertController
alertControllerWithTitle:@"Enter Folder Name"
message:@"Keep it short and sweet"
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction* ok = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action){
//Do Some action here
UITextField *textField = alert.textFields[0];
NSLog(@"text was %@",textField.text);
}];
UIAlertAction* cancel = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action) {
NSLog(@"cancel btn");
[alert dismissViewControllerAnimated:YES completion:nil];
}];
[alert addAction:ok];
[alert addAction:cancel];
[alert addTextFieldWithConfigurationHandler:^(UITextField *textField) {
textField.placeholder = @"folder name";
textField.keyboardType = UIKeyboardTypeDefault;
}];
[self presentViewController:alert animated:YES completion:nil];
}
else
{
// use UIAlertView
UIAlertView* dialog = [[UIAlertView alloc] initWithTitle:@"Enter Folder Name"
message:@"Keep it short and sweet"
delegate:self
cancelButtonTitle:@"Cancel"
otherButtonTitles:@"OK",nil];
dialog.alertViewStyle = UIAlertViewStylePlainTextInput;
dialog.tag = 400;
[dialog show];
}
这是Xcode 6模拟器中的错误还是我做错了？
