发送图片卡死问题

[ghost]

在聊天页面发送图片，如果图片过多时，在输入文字键盘弹出时点击语音按钮出现卡死现象。

-(void)keyboardChange:(NSNotification *)notification
{
NSDictionary *userInfo = [notification userInfo];
NSTimeInterval animationDuration;
UIViewAnimationCurve animationCurve;
CGRect keyboardEndFrame;

[[userInfo objectForKey:UIKeyboardAnimationCurveUserInfoKey] getValue:&animationCurve];
[[userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey] getValue:&animationDuration];
[[userInfo objectForKey:UIKeyboardFrameEndUserInfoKey] getValue:&keyboardEndFrame];

[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:animationDuration];
[UIView setAnimationCurve:animationCurve];

//adjust ChatTableView's height
if (notification.name == UIKeyboardWillShowNotification) {
    self.bottomConstraint.constant = keyboardEndFrame.size.height+40;
    //弹出键盘时，立马刷新
    [self.view layoutIfNeeded];
}else{
    self.bottomConstraint.constant = 40;
    //弹去键盘时，等下一个时间片执行
    [self.view setNeedsLayout];
}

//图片过多时，键盘弹下去用此方法会主线程堵塞

// [self.view layoutIfNeeded];

//adjust UUInputFunctionView's originPoint
CGRect newFrame = IFView.frame;
newFrame.origin.y = keyboardEndFrame.origin.y - newFrame.size.height;
IFView.frame = newFrame;

[UIView commitAnimations];

}

#import "SChatController.h"
在这个类里面修改就好了。
