是否可以在自定义键盘中启用与附加快照中相同的建议栏。如果没有,那么我将不得不创建自定义栏,因此我将不得不增加键盘的高度。你有增加键盘高度的代码吗?
最佳答案
尝试:(viewDidAppear
是UIInputViewController
子类的方法)
- (void)viewDidAppear {
[super viewDidAppear];
CGFloat _expandedHeight = 250;
NSLayoutConstraint *_heightConstraint = [NSLayoutConstraint constraintWithItem:self.view attribute:NSLayoutAttributeHeight relatedBy:NSLayoutRelationEqual toItem:nil attribute:NSLayoutAttributeNotAnAttribute multiplier:0.0 constant: _expandedHeight];
[self.view addConstraint: _heightConstraint];
}
警告:写入viewDidAppear:
方法
它不起作用。日志:

Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints)
(
"<NSLayoutConstraint:0x79829970 V:[UIInputView:0x79b2f660(250)]>",
"<NSLayoutConstraint:0x79824ea0 'UIView-Encapsulated-Layout-Height' V:[UIInputView:0x79b2f660(216)]>"
)
Will attempt to recover by breaking constraint
<NSLayoutConstraint:0x79829970 V:[UIInputView:0x79b2f660(250)]>
Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.
