我很努力地将UIButton添加到屏幕底部的工具栏中,问题在于它看起来并不在工具栏的顶部,而隐藏在它的下面。如何以编程方式将UIButton添加到工具栏上?
工具栏的代码我试图将它添加到(以及我的回退按钮代码下面)是;
请忽略坐标,因为它们不是100%,但iPhone版本至少应该显示在工具栏上,因为它在同一区域附近,我可以在之后进行调整。
//Insert Main Toolbar On Main View
if (IS_IPHONE_5) {
//offsetY = (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) ? 6 : 6 * 2;
offsetY = (1136 - 960)/2;
frameRect = CGRectMake(0, SCREEN_HEIGHT - 53, 320 * 2, 53);
}else if (IS_IPHONE || IS_IPHONE_4) {
offsetY = 0;
frameRect = CGRectMake(0, SCREEN_HEIGHT - 53, 320 * 2, 53);
} else {
frameRect = CGRectMake(0, 1024 - 53 * 2, 768 * 2, 53 * 2);
}
offsetY = (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) ? 6 : 6 * 2;
main_toolbar = [[UIImageView alloc] initWithFrame:frameRect];
[main_toolbar setImage:[UIImage imageNamed:[g_AppUtils resourceNameForDevice:@"ToolbarBackground" ofType:@"png"]]];
main_toolbar.userInteractionEnabled = YES;
[self.view addSubview:main_toolbar];
[main_toolbar release];
//Insert Go Back Button On Main Toolbar
goHome_button = [[UIButton alloc] initWithFrame:frameRect];
goHome_button = [UIButton buttonWithType:UIButtonTypeCustom];
[goHome_button setImage:[UIImage imageNamed:@"BackButton.png"] forState:UIControlStateNormal];
[goHome_button addTarget:self action:@selector(backButtonPressed:) forControlEvents:UIControlEventTouchUpInside];
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) {
goHome_button.frame = CGRectMake(55, 410, 46, 42);
} else {
goHome_button.frame = CGRectMake(80.0, 210.0, 160.0, 40.0);
}
[main_toolbar addSubview:goHome_button];
[self.view addSubview:goHome_button];
希望有任何帮助。
非常感谢! :) – user1695971
