光标出现在自定义的UITextField背景图像之前

Question

我有一个大小为360X44的背景图片，我试图将其作为我的UITextFields的背景，但它显示出一个意外的行为。光标在图像开始之前出现，但文本写在写入位置。

我的UiTextField的实施

UITextField *textFieldRounded = [[UITextField alloc] initWithFrame:CGRectMake(100, 75, 215, 30)];
textFieldRounded.borderStyle = UITextBorderStyleNone;
UIImage *fieldBGImage = [[UIImage imageNamed:@"textfield_normal.png"]  stretchableImageWithLeftCapWidth:50 topCapHeight:50];
[textFieldRounded setBackground:fieldBGImage];
textFieldRounded.textColor = [UIColor blackColor];
textFieldRounded.font = [UIFont systemFontOfSize:17.0];
textFieldRounded.placeholder = @"http://";  //place holder
textFieldRounded.backgroundColor = [UIColor whiteColor];
textFieldRounded.autocorrectionType = UITextAutocorrectionTypeNo;
textFieldRounded.backgroundColor = [UIColor clearColor];
textFieldRounded.keyboardType = UIKeyboardTypeDefault;
textFieldRounded.returnKeyType = UIReturnKeyDone;
textFieldRounded.clearsOnBeginEditing = NO;
textFieldRounded.clearButtonMode = UITextFieldViewModeWhileEditing;    
[self.view addSubview:textFieldRounded];    
textFieldRounded.delegate = self;

Answer 1

我只是将文字字段背景图像设置为我的波纹管代码并且工作良好： -

        [YourTextFiled setFont:[UIFont systemFontOfSize:18]];
        YourTextFiled.textAlignment = UITextAlignmentLeft;
        YourTextFiled.leftView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 12, 20)];
        YourTextFiled.leftViewMode = UITextFieldViewModeAlways;
        YourTextFiled.background = [[UIImage imageNamed:@"xFOEr.png"] stretchableImageWithLeftCapWidth:7 topCapHeight:17];

看起来像“ -

我建议不要添加图片作为背景颜色。将其添加为其他组件。即首先添加UIImageView，然后在其上添加UITextField。

同时尝试在当前代码中进行此更改：

UITextField *textFieldRounded = [[UITextField alloc] initWithFrame:CGRectMake(100, 75, 360, 44)];

Answer 3

UITextView *textView = [[UITextView alloc]initWithFrame: window.frame];
textView.text = @"text\n text\n text";
UIImageView *imgView = [[UIImageView alloc]initWithFrame: textView.frame];
imgView.image = [UIImage imageNamed: @"myImage.jpg"];
[textView addSubview: imgView];
[textView sendSubviewToBack: imgView];
[window addSubview: textView];

不要使用背景属性。将图像添加为子视图并将子视图发送回。
