blocks|key|4686948|text|因此，我发现解决此问题的唯一方法是使用textFieldDidBeginEditing和textFieldDidEndEditing委托方法，跟踪在文本字段中输入的内容，将其替换为项目符号掩码，并禁用secureTextEntry。因此，当他们离开现场时，他们实际上只是看到了正确数量的子弹，而不是他们的安全文本。这是老生常谈和凌乱，但它对我，也许对你也行。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4686949|entityMap^0|J|O|18|M|2S|F|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]|$9|M|A|N|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|O|8|@]|D|@]|E|$]]]|G|$]]

So, the only way I found to combat this was to use the <code>textFieldDidBeginEditing</code> and <code>textFieldDidEndEditing</code> delegate methods, keep track of what was entered in the text field, replace it with a mask of bullets, and disable <code>secureTextEntry</code>. So, when they leave the field, they’re actually just seeing the right number of bullets, rather than their secured text. It’s hacky and messy, but it’ll do for me, perhaps for you, too.

blocks|key|4687024|text|另一种解决方法：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4687025|虽然这是一个iOS错误(我应该补充说，这是iOS+7中的新错误)，但我确实有另一种方法来解决它，人们可能会发现可以接受。功能仍有轻微降级，但降级不大。|4687026|基本上，只要字段中输入了某些内容，就将字体设置为默认的字体系列/样式；但如果没有输入任何内容，则将其设置为您的自定义字体。(字体大小可以保持不变，因为它是系列/样式，而不是大小。)捕获字段值的每次更改，并在此时相应地设置字体。然后，当没有输入任何内容时，模糊的“提示”文本将具有您想要的字体(自定义)；但当输入任何内容(无论您是否正在编辑)时，将使用默认字体(Helvetica)。既然子弹就是子弹，这看起来应该没问题。|4687027|缺点之一是，字符在被项目符号替换之前键入时，将使用默认字体(Helvetica)。不过，这只是针对每个字符的瞬间。如果这是可以接受的，那么这个解决方案是可行的。|4687028|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|K|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|L|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|M|8|@]|9|@]|A|$]]|$1|H|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|I|$]]

Another workaround:

While this is an iOS bug (and new in iOS 7, I should add), I do have another way to work around it that one might find acceptable. The functionality is still slightly degraded but not by much. 

Basically, the idea is to set the font to the default font family/style whenever the field has something entered in it; but when nothing is entered, set it to your custom font. (The font size can be left alone, as it's the family/style, not the size, that is buggy.) Trap every change of the field's value and set the font accordingly at that time. Then the faint "hint" text when nothing is entered has the font that you want (custom); but when anything is entered (whether you are editing or not) will use default (Helvetica). Since bullets are bullets, this should look fine.

The one downside is that the characters, as you type before being replaced by bullets, will use default font (Helvetica). That's only for a split second per character though. If that is acceptable, then this solution works.

blocks|key|4687064|text|我找到了一个简单的解决方案，而且效果很好。基本上，当您将secureTextEntry设置为yes时，您必须将字体更改为自定义字体。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4687065|-+(void)textFieldDidBeginEditing:(UITextField+*)textField{

I found an easy solution an it works quite good.
Basically you have to change the font to a custom font when you set secureTextEntry to yes.

<pre><code>- (void)textFieldDidBeginEditing:(UITextField *)textField{

 if([textField.text isEqual:@"Password"]){
 textField.text = @"";
 textField.font = [UIFont fontWithName:@"Helvetica" size:14.5];
 textField.secureTextEntry = YES;
 }
}

- (void)textFieldDidEndEditing:(UITextField *)textField{

 if([textField.text isEqual:@""]){
 textField.text = @"Password";
 textField.secureTextEntry = NO;
 textField.font = [UIFont fontWithName:@"YourFont" size:14.5];
 }
}
</code></pre>

blocks|key|180983|text|我刚刚测试了上面的结果，@Javier+Peigneux的答案是最简洁的|type|unstyled|depth|inlineStyleRanges|entityRanges|data|180984|#pragma+mark+--+UITextFieldDelegate

i just test result above, @Javier Peigneux's answer is the most concise 

<pre><code>#pragma mark -- UITextFieldDelegate

- (void)textFieldDidBeginEditing:(UCSSafeTF *)safeTF{

 safeTF.font = [UIFont fontWithName:@"Helvetica" size:14];
}

- (void)textFieldDidEndEditing:(UCSSafeTF *)safeTF{

 safeTF.font = [UIFont fontWithName:@"Helvetica" size:14];
}
</code></pre>

now i write like this, and the result is OK. then the reason why you see the bullets size change from small to big is very clear, just because apple iOS 10 below "help" us resize the custom font. hope will help you .

I have a <code>UITextField</code> that is using the Museo Sans Rounded 300 font. Everything works fine for normal UITextFields, but when you set the <code>secureTextEntry = YES</code>, then there's this disconcerting change to the size of the bullets as the UITextField gets and loses focus (i.e. becomes, and relinquishes, being the first responder).

When the <code>UITextField</code> has focus, the bullets appear to be using the custom font, but once it loses focus they change to being these much bigger (standard size) bullets.

我有一个UITextField，它使用的是Museo Sans Rounded 300字体。对于普通的UITextFields来说，一切都很好，但当你设置secureTextEntry = YES时，随着UITextField获得和失去焦点(即成为第一个响应者，然后放弃)，子弹的大小会发生令人不安的变化。当UIText...
