我一直在试图找出一些可能很明显的东西,但我错过了重点或失去了重点。XCode 没有看到的 toggleStormButtons 函数有问题吗?
在我的主类中,我有以下调用另一个类中的函数:
STopLeftMenu *mTopLeft = [[STopLeftMenu alloc]init];
[mTopLeft drawStormToggleButton];
然后在另一个类中,我有 2 个功能:
- (void)toggleStormButtons{
[UIButton animateWithDuration:0.50 animations:^{
if (stormToggleBtn.transform.tx == 0){
[stormToggleBtn setTransform:CGAffineTransformMakeTranslation(307, 0)];
UIImage* hideButtonImg = [UIImage imageNamed:@"aiga_right_arrow_mod_hide_resize.png"];
[stormToggleBtn setBackgroundImage:hideButtonImg forState:UIControlStateNormal];
}
else{
[stormToggleBtn setTransform:CGAffineTransformMakeTranslation(0, 0)];
UIImage* showButtonImg = [UIImage imageNamed:@"aiga_right_arrow_mod_show_resize.png"];
[stormToggleBtn setBackgroundImage:showButtonImg forState:UIControlStateNormal];
}
}];
for(UIView* storm in stormButtonSaves){
[UIView animateWithDuration:0.50 animations:^{
if (storm.transform.tx == 0){
[storm setTransform:CGAffineTransformMakeTranslation(307, 0)];
storm.alpha = .65;
}
else{
[storm setTransform:CGAffineTransformMakeTranslation(0, 0)];
storm.alpha = 0;
}
}];
}
}
- (void)drawStormToggleButton{
//Storm Pullout Toggle Button
UIImage *buttonImageNormal = [UIImage imageNamed:@"aiga_right_arrow_mod_show_resize.png"];
stormToggleBtn = [[UIButton alloc] initWithFrame:CGRectMake(10, 10, 65, 75) ];
[stormToggleBtn setBackgroundImage:buttonImageNormal forState:UIControlStateNormal];
stormToggleBtn.backgroundColor = [UIColor clearColor];
stormToggleBtn.alpha = 0.5;
[stormToggleBtn addTarget:self action:@selector(toggleStormButtons) forControlEvents:UIControlEventTouchUpInside];
[viewsToRemove addObject:stormToggleBtn];
[mv addSubview:stormToggleBtn];
}
我似乎收到了无法识别的选择器消息:
