iphone - 向 UITextView 添加左边距

Question

我正在尝试向 UITextView 添加左边距。

我试过设置属性 contentInset，见下文:

UITextView *textView = [[UITextView alloc] initWithFrame: CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height)];
textView.editable = YES;
textView.autoresizingMask = UIViewAutoresizingFlexibleHeight;
textView.backgroundColor = [UIColor clearColor];
textView.opaque = NO;
textView.contentInset = UIEdgeInsetsMake(0, 15.0f, 0, 0);

虽然它会导致我不想要的 TextView 上的水平滚动，但这似乎可行。

我只想在左侧插入文本而不使 TextView 变宽。

Answer 1

请记住，对于 iOS 7，有一个名为

的特殊属性

textContainerInset The inset of the text container's layout area within the text view's content area.

@property(nonatomic, assign) UIEdgeInsets textContainerInset

This property provides text margins for text laid out in the text view.

Availability Available in iOS 7.0 and later. Declared In UITextView.h

在 iOS 6 中，contentInset 正在做这项工作。我个人遇到过这个问题。一切都结束了:

if (isIOS7()) {
    textView.textContainerInset = UIEdgeInsetsMake(0, 10, 0, 10);
} else {
    textView.contentInset = UIEdgeInsetsMake(0, 10, 0, 10);
}
