在中文手写输入法输入时,会导致app崩溃,在debug时,报错为:2014-10-22 14:45:10.269 App[524:170755] -[UIKBBlurredKeyView candidateList]: unrecognized selector sent to instance 0x16ff44b0经过一番折腾,确认是- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event错误使用导致的。在某个不相关的视图控制器类以前加了下列代码。@implementation UIScrollView (touch)- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{ // If not dragging, send event to next responder if (!self.dragging) { [self.nextResponder touchesBegan:touches withEvent:event]; } else { [super touchesEnded:touches withEvent:event]; }}- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event{ // If not dragging, send event to next responder if (!self.dragging) { [self.nextResponder touchesBegan:touches withEvent:event]; } else { [super touchesEnded:touches withEvent:event]; }}- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{ // If not dragging, send event to next responder if (!self.dragging) { [self.nextResponder touchesBegan:touches withEvent:event]; } else { [super touchesEnded:touches withEvent:event]; }}但是,这里有两个问题。一,我开始使用xcode6的搜索功能,但没有找到这个代码。因为搜索没有找到这段代码,导致后来的折腾时间延长。因此,xcode6的搜索功能不可信。二,这段代码存在于一个不相关的视图控制器类,虽然该类被main.storyboard应用了,但并没有加载,我以为没有应用到全局应用代码里。现在看来不是,一样对整个应用代码生效。 |
