iPhone: Issue disabling Auto-Cap/autocorrect on a UITextField
提问by phil swenson
For some reason, even though I disable the auto-cap and auto-correct of my UITextField, it's still capitalizing the first letter of my input.
出于某种原因，即使我禁用了 UITextField 的自动大写和自动更正，它仍然大写我输入的第一个字母。
Here is the code:
这是代码：
UITextField* textField = [[[UITextField alloc] initWithFrame:CGRectMake(90.0, 10.0, 213.0, 25.0)] autorelease];
[textField setClearButtonMode:UITextFieldViewModeWhileEditing];
textField.returnKeyType = UIReturnKeyGo;
textField.autocorrectionType = FALSE;
textField.autocapitalizationType = UITextAutocapitalizationTypeNone;
textField.delegate = self;
if (inputFieldType == Email) {
label.text = @"Email:";
textField.keyboardType = UIKeyboardTypeEmailAddress;
emailTextField = textField;
textField.placeholder = @"Email Address";
} else { // password
textField.secureTextEntry = TRUE;
label.text = @"Password:";
if (inputFieldType == Password){
textField.placeholder = @"Password";
passwordTextField = textField;
}
if (inputFieldType == ConfirmPassword){
textField.placeholder = @"Confirm Password";
confirmPasswordTextField = textField;
}
}

You're setting autocorrectionTypeto FALSEas if it were a BOOL, but it actually has type UITextAutocorrectionType. So FALSEis being interpreted as UITextAutocorrectionTypeDefault, which means that autocorrection is probably enabled.
你设置autocorrectionType到FALSE就好像它是一个BOOL，但它实际上有型UITextAutocorrectionType。所以FALSE被解释为UITextAutocorrectionTypeDefault，这意味着可能启用了自动更正。
I bet it found the name "Phil" in your address book and is autocorrecting the capitalization to match.
我敢打赌，它在你的地址簿中找到的名称“菲尔”，并自动更正大小写相匹配。

-(void)textFieldDidBeginEditing:(UITextField *)textField
{
textField.autocorrectionType = FALSE; // or use UITextAutocorrectionTypeNo
textField.autocapitalizationType = UITextAutocapitalizationTypeNone;
}
Swift
迅速
func textFieldDidBeginEditing(textfield : UITextField)
{
textField.autocorrectionType = .No
textField.autocapitalizationType = .None
textField.spellCheckingType = .No
}

If you wish to disable Auto-Cap/autocorrect on a UITextField for whole project,
如果您希望在整个项目的 UITextField 上禁用自动大写/自动更正，
then make a class which will inherit the UITextField class and init method set the autoCorrectionType to "no".
然后创建一个将继承 UITextField 类和 init 方法的类，将 autoCorrectionType 设置为“no”。
Class AppTextField: UITextField {
override init(frame: CGRect) {
super.init(frame: frame)
//setting the autocorrection to no
self.autocorrectionType = .no
}
}
Then in storyboard set the cusotom class for textfield to AppTextField.
然后在情节提要中将文本字段的自定义类设置为 AppTextField。
