I’m using a custom font in a UITextField
, which has secureTextEntry
turned on. When I’m typing in the cell, I see the bullets in my chosen font, but when the field loses focus, those bullets revert to the system standard font. If I tap the field again, they change back to my font, and so on.
Is there a way I can ensure that they continue to display the custom font’s bullets, even when the field is out of focus?
A subclass that works this issue around. Create an arbitrary UITextField
, then set the secure
property to YES
(via KVC in IB).
Actually it implements a comment suggested by lukech. When textfield ends editing, it switches to an arbitrary textfield, then set a bulk of dots into, and some hack in text
accessor to always get the actual text the field holds.
@interface SecureTextFieldWithCustomFont : UITextField
@property (nonatomic) BOOL secure;
@property (nonatomic, strong) NSString *actualText;
@end
@implementation SecureTextFieldWithCustomFont
-(void)awakeFromNib
{
[super awakeFromNib];
if (self.secureTextEntry)
{
// Listen for changes.
[self addTarget:self action:@selector(editingDidBegin) forControlEvents:UIControlEventEditingDidBegin];
[self addTarget:self action:@selector(editingDidChange) forControlEvents:UIControlEventEditingChanged];
[self addTarget:self action:@selector(editingDidFinish) forControlEvents:UIControlEventEditingDidEnd];
}
}
-(NSString*)text
{
if (self.editing || self.secure == NO)
{ return [super text]; }
else
{ return self.actualText; }
}
-(void)editingDidBegin
{
self.secureTextEntry = YES;
self.text = self.actualText;
}
-(void)editingDidChange
{ self.actualText = self.text; }
-(void)editingDidFinish
{
self.secureTextEntry = NO;
self.actualText = self.text;
self.text = [self dotPlaceholder];
}
-(NSString*)dotPlaceholder
{
int index = 0;
NSMutableString *dots = @"".mutableCopy;
while (index < self.text.length)
{ [dots appendString:@"•"]; index++; }
return dots;
}
@end
May be augmented to work with non NIB instantiations, handling default values, etc, but you probably get the idea.
