I try to make out some quiz and have a problem with my answer buttons. Simple fact: The text is too long and I try to auto-adjust it for cells using different methods. My current status:
for btn in btnArr{
btn.titleLabel!.minimumScaleFactor = 0.3
btn.titleLabel!.numberOfLines = 0
btn.titleLabel!.adjustsFontSizeToFitWidth = true
btn.titleLabel?.baselineAdjustment = UIBaselineAdjustment.AlignCenters
//btn.contentEdgeInsets = UIEdgeInsets(top: 3.0,left: 3.0,bottom: 3.0,right: 3.0)
}
I hope somebody has another option for me to make that work :)
Regards, Patrick
EDIT:
self.view.addConstraint(NSLayoutConstraint(item: btn.titleLabel!, attribute: NSLayoutAttribute.Height, relatedBy: NSLayoutRelation.Equal, toItem: btn, attribute:NSLayoutAttribute.Height, multiplier: 0.99, constant: 0))
With auto layout you can set the space between buttons, and the max and min size. In code for all labels use:
self.button.titleLabel.numberOfLines = 0;
self.button.titleLabel.adjustsFontSizeToFitWidth = YES;
With this all labels adjust the text will size.
For adjust button to titleLabel use auto layout constraint for titleLabel. For examples:
[self.view addConstraint:[NSLayoutConstraint constraintWithItem:self.button.titleLabel
attribute:NSLayoutAttributeHeight
relatedBy:NSLayoutRelationEqual
toItem:self.view
attribute:NSLayoutAttributeHeight
multiplier:0.5
constant:0]];
This constraint define the height of titleLabel to 50% of self.view
height. Now you can adapte the constraint for that you need.
This work in you code?
假设单元格的高度和字体相同,则可以通过将“ numberOfLines”设置为非0的值(例如3或4)来限制文本。
