Right aligned UITextField spacebar does not advance cursor in iOS 7

Question

In my iPad app, I noticed different behavior between iOS 6 and iOS 7 with UITextFields.

I create the UITextField as follows:

UIButton *theButton = (U

I've came up with a solution that subclasses the UITextField class and performs the swap, without the need of copying and pasting code everywhere. This also avoids using method sizzle to fix this.

@implementation CustomTextField

-(id) initWithCoder:(NSCoder *)aDecoder {
    self = [super initWithCoder:aDecoder];

    if( self ) {

        [self addSpaceFixActions];
    }

    return self;
}

- (void)addSpaceFixActions {
    [self addTarget:self action:@selector(replaceNormalSpaces) forControlEvents:UIControlEventEditingChanged];
    [self addTarget:self action:@selector(replaceBlankSpaces) forControlEvents:UIControlEventEditingDidEnd];
}


//replace normal spaces with non-breaking spaces.
- (void)replaceNormalSpaces {
    if (self.textAlignment == NSTextAlignmentRight) {
        UITextRange *textRange = self.selectedTextRange;
        self.text = [self.text stringByReplacingOccurrencesOfString:@" " withString:@"\u00a0"];
        [self setSelectedTextRange:textRange];
    }
}

//replace non-breaking spaces with normal spaces.
- (void)replaceBlankSpaces {
    self.text = [self.text stringByReplacingOccurrencesOfString:@"\u00a0" withString:@" "];
}
