我正在努力将 UIButton 添加到屏幕底部的工具栏,问题是它似乎没有出现在工具栏的顶部,而是隐藏在它的下方。
我试图将其添加到的工具栏代码(以及下面的返回按钮代码)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,因为它在同一区域周围,我可以在之后调整它。
//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];
