how to avoid dots next to a uitextfield

问题

Is that possible to remove the dots which are displayed next to uitextfield when text is larger than the width of the uitextfield.

回答1:

There is a property lineBreakMode which defines the behaviour when the text to be displayed is larger than the box of the control

//UILineBreakMode
//Options for wrapping and truncating text.

typedef enum {
 UILineBreakModeWordWrap = 0,
 UILineBreakModeCharacterWrap,
 UILineBreakModeClip,
 UILineBreakModeHeadTruncation,
 UILineBreakModeTailTruncation,
 UILineBreakModeMiddleTruncation,
} UILineBreakMode;

If you do not want any dots you can use UILineBreakModeClip which simply cuts the text off at the end. The apple doc says this:

Clip the text when the end of the drawing rectangle is reached. This option could result in a partially rendered character at the end of a string. Available in iPhone OS 2.0 and later.

Although it of course depends on how you want to display the text. Since either way you cannot display all of the text the dots are usually more asthetic than a raw break.

If you require absolutely all of the text to be visible you must either expand the width of the field, or the height (and use UILineBreakModeCharacterWrap), or possibly decrease the font size (as a last resort).

It is possible if you make keyboard visible calling following code

[self.yourTextField becomeFirstResponder];

Then larger text is clipped from left.

you can also hide keyboard [if you use any custom keyboard] using following code

// Hide keyboard for Dial Pad, but show blinking cursor
UIView *dummyKeyboardView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 1, 1)];
yourTextField.inputView = dummyKeyboardView;
[dummyKeyboardView release];

I tried lots of ways and finally I came to following solution.

UITextField does not have a lineBreakMode property so just override following method in UITextField:

-(CGRect)textRectForBounds:(CGRect)bounds{

    CGRect rect = bounds;
    rect.size.width = rect.size.width;
    return rect;
}

Note: I dont know how, but it works.
