我希望在动画完成后运行一段代码,但编译器显示以下错误：“不兼容的块指针类型向’void(^)(BOOL)’类型的参数发送’void(^)(void)’”
这是我的代码,我不确定我做错了什么,请帮助,谢谢.
[UIView transitionWithView:self.view duration:1.5
options:UIViewAnimationOptionTransitionFlipFromBottom //change to whatever animation you like
animations:^ {
[self.view addSubview:myImageView1];
[self.view addSubview:myImageView2];
}
completion:^ {
NSLog(@"Animations completed.");
// do something...
}];
解决方法
你只是有错误的块类型:)它需要一个像下面这样的块.关键是^(BOOL完成){…}
[UIView transitionWithView:self.view duration:1.5
options:UIViewAnimationOptionTransitionFlipFromBottom //change to whatever animation you like
animations:^ {
[self.view addSubview:myImageView1];
[self.view addSubview:myImageView2];
}
completion:^(BOOL finished){
if (finished) {
// Successful
}
NSLog(@"Animations completed.");
// do something...
}];
