i 正在使用<条码>UITextView,并且希望将空间从<条码>上删除。

Answer 1

我已更新上述法典。尝试。 i 认为是希望的结果。

// Create a size with large height, but matching width to UITextView.
[myTextView setBackgroundColor:[UIColor greenColor]];
CGSize maxSize = CGSizeMake(myTextView.frame.size.width, 20);

// Determine the size needed to display the text - we just need the new height.
CGSize textSize = [myTextView.text sizeWithFont:myTextView.font constrainedToSize:maxSize lineBreakMode:UILineBreakModeWordWrap];

// Set the UITextView s frame to the new height.
CGRect textViewRect = myTextView.frame;
textViewRect.size.height = textSize.height+13;
myTextView.frame = textViewRect;

Answer 2

Something like this?

textView.text = [textView.text • 铺设ByTrimingCharactersInSet And NewlineCharacter 内容提要

Answer 3

I m assuming/guessing you wish to resize a UITextView to accommodate the text nicely. If so, I suggest you investigate:

- (CGSize)sizeWithFont:(UIFont *)font constrainedToSize:(CGSize)size lineBreakMode:(UILineBreakMode)lineBreakMode;

例如:

// Create a size with large height, but matching width to UITextView.
CGSize maxSize = CGSizeMake(myTextView.frame.size.width, 9999);

// Determine the size needed to display the text - we just need the new height.
CGSize textSize = [myTextView.text sizeWithFont:myTextView.font constrainedToSize:maxSize lineBreakMode:UILineBreakModeWordWrap];

// Set the UITextView s frame to the new height.
CGRect textViewRect = myTextView.frame;
textViewRect.size.height = textSize.height;
myTextView.frame = textViewRect;
