如何簡化文本字段的左右填充

Question

我已經有了為所有文本字段創建填充的解決方案，但是我認為我需要簡化它，因為我認為這太手工了：

// Padding Left and Right for textfield
UIView *fieldEmail = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 10, 10)];
_fieldEmail.leftViewMode = UITextFieldViewModeAlways;
_fieldEmail.leftView = fieldEmail;

UIView *fieldPassword = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 10, 10)];
_fieldPassword.leftViewMode = UITextFieldViewModeAlways;
_fieldPassword.leftView = fieldPassword;

UIView *fieldRegisterName = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 10, 10)];
_fieldRegisterName.leftViewMode = UITextFieldViewModeAlways;
_fieldRegisterName.leftView = fieldRegisterName;

UIView *fieldRegisterEmail = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 10, 10)];
_fieldRegisterEmail.leftViewMode = UITextFieldViewModeAlways;
_fieldRegisterEmail.leftView = fieldRegisterEmail;

UIView *fieldRegisterPassword = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 10, 10)];
_fieldRegisterPassword.leftViewMode = UITextFieldViewModeAlways;
_fieldRegisterPassword.leftView = fieldRegisterPassword;

我們可以創建循環之類的東西，以便這種填充可以影響我的所有文本字段嗎？ 如何簡化呢？

謝謝。

Answer 1

您可以textRectForBounds UITextField並重寫textRectForBounds ， editingRectForBounds和drawPlaceholderInRect 。 這已經在SSToolkit SSTextField完成。 您可以這樣使用它：

textField.textEdgeInsets = UIEdgeInsetsMake(0, 0, 10, 10)

如果要對所有文本字段使用相同的插圖，則只需對該值進行子類化和編碼。
