How to set content inset for UITextView in ios

问题

I'm having a UITextView and set content inset as

[atextView setContentInset:UIEdgeInsetsMake(0, 10, 0, 0)];

This code working in iOS 6.1 and below, but nothing happens in iOS 7.0.

回答1:

got answer:

[atextView  setTextContainerInset:UIEdgeInsetsMake(7, 7, 0, 0)];

fixed my problem.

And in Swift...

@IBOutlet var tv:UITextView!
override func awakeFromNib() {
    super.awakeFromNib()
    tv.textContainerInset = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0)
}

UPDATE: another option to do that.

UIView *spacerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 10, 10)];
[msgtext setLeftViewMode:UITextFieldViewModeAlways];
[msgtext setLeftView:spacerView];

回答2:

An alternative and maybe a little more convenient way to do it, by subclassing the UITextField and add an @IBInspectable inset property.

import UIKit

class UITextfieldWithInset: UITextField {

    @IBInspectable
    var textfieldInset: CGPoint = CGPointMake(0, 0)

    override func textRectForBounds(bounds: CGRect) -> CGRect {
        return CGRectInset(bounds, textfieldInset.x, textfieldInset.y)
    }

    override func editingRectForBounds(bounds: CGRect) -> CGRect {
        return CGRectInset(bounds, textfieldInset.x, textfieldInset.y)
    }

    override func placeholderRectForBounds(bounds: CGRect) -> CGRect {
        return CGRectInset(bounds, textfieldInset.x, textfieldInset.y)
    }

}
