將UITextField對齊設置爲正確

Question

我正在使用iPhone6 +和iOS 8.3。

當，我想設置UITextField對齊到右側。但是當我發送它時，輸入文本跳轉到左側。

[tf setBackgroundColor:[UIColor clearColor]]; 
tf.attributedPlaceholder = [[NSAttributedString alloc] initWithString:placeholder attributes:@{NSForegroundColorAttributeName:ISMColor(123, 123, 129)}]; 
tf.delegate = self; 
tf.placeholder = placeholder; 
[tf setTextAlignment:NSTextAlignmentRight]; 
[tf setContentHorizontalAlignment:UIControlContentHorizontalAlignmentRight]; 

Answer 1

嘗試實現這個委託方法：

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string { 
    // only when adding on the end of textfield && it's a space 
    if (range.location == textField.text.length && [string isEqualToString:@" "]) { 
     // ignore replacement string and add your own 
     textField.text = [textField.text stringByAppendingString:@"\u00a0"]; 
     return NO; 
    } 
    // for all other cases, proceed with replacement 
    return YES; 
}
