Objective c 无法将UITextField添加到iOS 7上的UIAlertView…在iOS 6中工作
下面的代码在iOS6（和之前的版本）上运行，但UITextField在iOS7中不显示……关于如何在iOS7的UIAlterView中显示UITextField，您有什么想法吗Objective c 无法将UITextField添加到iOS 7上的UIAlertView…在iOS 6中工作,objective-c,ios7,uitextfield,uialertview,uialertviewdelegate,Objective C,Ios7,Uitextfield,Uialertview,Uialertviewdelegate,下面的代码在iOS6（和之前的版本）上运行，但UITextField在iOS7中不显示……关于如何在iOS7的UIAlterView中显示UITextField，您有什么想法吗 UIAlertView* dialog = [[UIAlertView alloc] init]; [dialog setDelegate:self]; [dialog setTitle:@"Enter ESC Score"]; [dialog setMessage:@" "]; [dialog addButtonWit

在iOS 7中，您无法轻松更改UIAlertView的视图层次结构。（您也不应该这样做；文档明确告诉您不要这样做。）前往开发人员论坛，查看关于它的长时间讨论
在您的情况下，另一种选择是设置
alert.alertViewStyle=UIAlertViewStylePlainTextInput这将为您添加一个文本字段。您可以使用UITextField*textField=[alertView textfieldatinex:0]在UIAlertView委托回调中访问它@Aaron Brager找到了正确的解决方案。此外，我在他的建议后添加了一行，默认使用数字键盘
UIAlertView* dialog = [[UIAlertView alloc] init];
[dialog setDelegate:self];
[dialog setTitle:@"Enter ESC Score"];
[dialog setMessage:@" "];
[dialog addButtonWithTitle:@"Cancel"];
[dialog addButtonWithTitle:@"OK"];
dialog.tag = 5;
dialog.alertViewStyle = UIAlertViewStylePlainTextInput;
[dialog textFieldAtIndex:0].keyboardType = UIKeyboardTypeNumberPad;
CGAffineTransform moveUp = CGAffineTransformMakeTranslation(0.0, 0.0);
[dialog setTransform: moveUp];
[dialog show];
[dialog release];
1） 方法
-（id）initWithAlertTitle:（NSString*）密码的标题检查：（NSString*）密码
你应该加上
self.alertViewStyle = UIAlertViewStylePlainTextInput;
样本：
(id)initWithAlertTitle:(NSString *)title
checkForPassword:(NSString *)password{
if(SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0"))
{
self.alertViewStyle = UIAlertViewStylePlainTextInput;
}
self = [super initWithTitle:title
message:@"" // password field will go here
delegate:self
cancelButtonTitle:@"Cancel"
otherButtonTitles:@"Enter", nil];
if (self) {
self.password = password;
self.hashTechnique = HashTechniqueNone; // use no hashing by default
secondMessage = @"Please Enter New Password";
thirdMessage = @"Please Re-Enter Password";
secondMessageNew = @"Please Enter Password";
}
NSLog(@" _password_ %@",_password);
NSLog(@"_old_password_ %@",[[NSUserDefaults standardUserDefaults] objectForKey:kPassword]);
return self;
}
在方法展示中
添加下一个
(void)show {
if(SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0"))
{
UITextField *passwordField = [self textFieldAtIndex:0];
passwordField.delegate = self;
self.passwordField = passwordField;
}
else
{
UITextField *passwordField = [[UITextField alloc] initWithFrame:CGRectMake(14, 45, 256, 25)];
passwordField.secureTextEntry = YES;
passwordField.placeholder = @"";
passwordField.backgroundColor = [UIColor whiteColor];
// Pad out the left side of the view to properly inset the text
UIView *paddingView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 6, 19)];
passwordField.leftView = paddingView;
passwordField.leftViewMode = UITextFieldViewModeAlways;
// // Set delegate
self.passwordField.delegate = self;
// Set as property
self.passwordField = passwordField;
// Add to subview
[self addSubview:_passwordField];
}
// Show alert
[super show];
}
还可以在方法单击中进行更改
#pragma mark - UIAlertViewDelegate
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
if(SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0"))
{
UITextField *passwordField = [self textFieldAtIndex:0];
self.passwordField = passwordField;
}
if (buttonIndex == alertView.firstOtherButtonIndex) {
if ([self enteredTextIsCorrect] || [self.title isEqualToString:secondMessage] || [self.title isEqualToString:secondMessageNew]) {
if (([self.title isEqualToString:secondMessage] || [self.title isEqualToString:secondMessageNew]) && (self.passwordField.text.length > 0)) {
self.password = self.passwordField.text;
self.title = thirdMessage;
self.passwordField.text = @"";
if(SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0"))
{
if ([self.passwordDelegate respondsToSelector:@selector(notifyParent::)]) {
[self.passwordDelegate notifyParent:thirdMessage:self.password];
}
}
}else
{
if ([self.title isEqualToString:thirdMessage]) {
[[NSUserDefaults standardUserDefaults] setObject:self.password forKey:kPassword];
[[NSUserDefaults standardUserDefaults] synchronize];
if (self.passwordDelegate) {
if ([self.passwordDelegate respondsToSelector:@selector(notifyParentWithState:)]) {
[self.passwordDelegate notifyParentWithState:YES];
}
}
}else{
if ([self.title isEqualToString:secondMessageNew]) {
self.title = secondMessageNew;
}
else{
self.title = secondMessage;
}
self.passwordField.text = @"";
if(SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0"))
{
if ([self.passwordDelegate respondsToSelector:@selector(notifyParent::)]) {
[self.passwordDelegate notifyParent:self.title:self.password];
}
}
}
}
}
// If incorrect then animate
else {
[self animateIncorrectPassword];
}
}
}
您还可以在cocoacontrols.com上查看自定义控件。看看（类似ios 7的用户界面）和（类似ios 6的用户界面）。它们也可以被转换成旋转角度。就像魔咒一样
所有版本iOS的UIAlertView中有两个UIExtField
-(IBAction) showAlertView {
UIAlertView *alert;
UITextField *callForwardNumber;
UItextField *callForwardCondition;
alert = [[UIAlertView alloc] initWithTitle:@"Enter Phone Number & Rule"
message:@""
delegate:self
cancelButtonTitle:@"Cancel"
otherButtonTitles:@"Save", nil];
//alert.transform = CGAffineTransformMakeTranslation(0, 110);
callForwardNumber = [[UITextField alloc] init];
callForwardNumber.keyboardType = UIKeyboardTypeNumberPad;
callForwardNumber.text = [R.prefs objectForKey:@"fwd_number"];
callForwardNumber.borderStyle = UITextBorderStyleRoundedRect;
callForwardNumber.delegate = self;
callForwardNumber.tag = 1;
callForwardCondition = [[UITextField alloc] init];
callForwardCondition.text = callCondition;
callForwardCondition.borderStyle = UITextBorderStyleRoundedRect;
callForwardCondition.delegate = self;
callForwardCondition.tag = 2;
[callForwardCondition setKeyboardType:UIKeyboardTypeNumberPad];
if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1) {
UIView* customAccessory =
[[UIView alloc] initWithFrame:CGRectMake(0, 0, 250, 55)];
callForwardNumber.frame = CGRectMake(0, 0, 245.0, 25.0);
callForwardCondition.frame = CGRectMake(0, 30.0, 245.0, 25.0);
[customAccessory addSubview:callForwardNumber];
[customAccessory addSubview:callForwardCondition];
[alert setValue:customAccessory forKey:@"accessoryView"];
[alert show];
} else {
alert.message = @"\n\n\n";
[alert show];
callForwardNumber.frame = CGRectMake(20.0, 45.0, 245.0, 25.0);
callForwardCondition.frame = CGRectMake(20.0, 75.0, 245.0, 25.0);
[alert addSubview:callForwardNumber];
[alert addSubview:callForwardCondition];
}
}
我也面临着同样的问题，在冲浪的过程中我得到了答案，这对我来说很有效。我希望它对你也有用
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Folder Name?" message:@"" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Ok", nil];
alertView.tag = 2;
alertView.alertViewStyle = UIAlertViewStylePlainTextInput;
[alertView show];
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
UITextField * alertTextField = [alertView textFieldAtIndex:0];
NSLog(@"alerttextfiled - %@",alertTextField.text);
}
iOS7仍然是测试版，你到底期望什么呢？嗯……我想如果苹果将在9月中旬发布iOS7，我希望能够与一个有才华、聪明、志同道合的开发者社区合作，这样我们的应用程序就不会对成千上万的现有苹果用户无法使用。苹果不希望任何人谈论如何主动让用户满意，这似乎有点傻。那么，我们是否要假装iOS7在正式发布之前并不存在？NDA很重要，但这似乎很愚蠢……甚至更愚蠢的是，有人花时间来回答人们提出的iOS7问题和扣分。只是说……苹果提供了一个讨论iOS7的论坛，在这个论坛上可以讨论被禁止的API。这里关于未发布、可能无法运行的软件的讨论对其他人来说并没有太大用处——除非特别标注了版本号难以置信，还必须为ios 7安装全新的osx，难以置信！猜猜这一问题在iOS 7的公开发行版中出现了什么，我们的应用程序在这方面也被破坏了。任何使用这种技术的应用程序（其实并不少见）都会被破坏。我很抱歉，伙计们，回答“在保密协议下，对其他人没有用处”是完全错误的方法来维持一个富有成效的社区，它应该在现实世界的问题上相互帮助，这绝对是一个错误的方法。无论测试版与否，这些问题都是存在的——因此请对此保持建设性，而不是不屑一顾，也不要给问题增加任何价值。这对单个文本字段很有效。如果我想向uialertview添加两个文本字段，那么解决方案是什么？@loganathanUIAlertViewStyleLogin和PasswordInput
。如果不想隐藏第二个框，您可以设置[alertView textFieldAtIndex:1].secureTextEntry=NO
。对于任何比这更复杂的问题，请发表您自己的看法。@AaronBrager有意义：-）@AaronBrager，但它会被苹果应用程序评论接受吗？3个文本字段呢？我们将其用于密码重置功能：“当前密码、新密码、再次新密码”。遵循@Aaron Brager的建议并改变警报的配置方式。。。就像iTrout为我做的一样！谢谢你们两个！！！我的解决方案适用于iOS 5及以上版本（您仅在iOS 7及以上版本上使用）。除非你支持iOS 4，否则没有必要进行这种黑客攻击。此外，无论你从哪个应用程序复制了它，都会在NSUserDefaults中保存密码，这是一个糟糕的主意。
