如何在UITextField的開頭添加空間

Question

我正在創建一個包含多個UITextField的應用程序。 在textField中，我將邊框類型設置為無和背景圖像。 它顯示正常，但現在我的文本是從最小的邊框開始，看起來不太好，就像這樣

如何在文本字段的開頭添加空間？

Answer 1

試試這個

UILabel * leftView = [[UILabel alloc] initWithFrame:CGRectMake(10,0,7,26)];
leftView.backgroundColor = [UIColor clearColor];

textField.leftView = leftView;

textField.leftViewMode = UITextFieldViewModeAlways;
textField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;

Answer 2

這是@ Kalpesh在Swift 3.x中的答案：

let leftView = UILabel(frame: CGRectMake(10, 0.0, 7, 26))
leftView.backgroundColor = .clearColor()

customField.leftView = leftView
customField.leftViewMode = .Always
customField.contentVerticalAlignment = .Center

Swift 4.x

let leftView = UILabel(frame: CGRect(x: 10, y: 0, width: 7, height: 26))
leftView.backgroundColor =.clear

customField.leftView = leftView
customField.leftViewMode = .always
customField.contentVerticalAlignment = .center

Answer 3

您應該UITextField並覆蓋drawText函數。

檢查這個以獲得幫助或者你可以這樣做：

UIView *paddingView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 15, height_of_textfiled)];
textField.leftView = paddingView;
textField.leftViewMode = UITextFieldViewModeAlways;

目標c

對於僅填充占位符，此代碼將起作用

usernameTF.attributedPlaceholder = [[NSAttributedString alloc] initWithString:@"    Your text"];

為了填充UITextField的占位符和文本，下面的代碼將起作用

usernameTF.layer.sublayerTransform = CATransform3DMakeTranslation(40, 0, 30);

Swift 3.0

對於僅填充占位符，此代碼將起作用

yourTextField.attributedPlaceholder = NSAttributedString(string: "    YourText")

為了填充UITextField的占位符和文本，下面的代碼將起作用

usernameTF.layer.sublayerTransform = CATransform3DMakeTranslation(40, 0, 30)

Answer 5

您可以textRectForBounds UITextField並覆蓋textRectForBounds和editingRectForBounds 。

例如，

- (CGRect)textRectForBounds:(CGRect)bounds {
    return CGRectMake(bounds.origin.x + 10, bounds.origin.y + 5, bounds.size.width - 20, bounds.size.height - 10);
}

- (CGRect)editingRectForBounds:(CGRect)bounds {
    return CGRectMake(bounds.origin.x + 10, bounds.origin.y + 5, bounds.size.width - 20, bounds.size.height - 10);
}

斯威夫特4

yourTextField.layer.sublayerTransform = CATransform3DMakeTranslation(10, 0, 10)

Answer 7

您可以將文本域背景圖像放在圖像視圖中，在imageview上方將文本字段留空。

Answer 8

-(void)textField:(UITextField *) textField didBeginEditing {
    if ([textField.text isEqualToString:@""] || textField.text == NULL) {
       textField.text = @" ";
    }
}
