Obj-C - 如何在地圖上添加菜單欄

Question

我想在圖像底部的地圖上創建一個菜單欄。 它的頂部有一個搜索欄，底部有三個按鈕。 如何將按鈕與圖片中的搜索欄連接起來？ 謝謝你。

解決方案：

我跟着ezatu丶代碼做了一些改動：

• `UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect:searchBar.bounds byRoundingCorners:(UIRectCornerTopLeft | UIRectCornerTopRight)cornerRadii:CGSizeMake(6, 6)];

  CAShapeLayer *maskLayer = [CAShapeLayer 圖層];

  maskLayer.path = maskPath.CGPath;

  searchBar.layer.mask = maskLayer;

  [toolView addSubview:searchBar];` 創建圓角和陰影，同樣的代碼將按鈕放入for循環。

• 視圖的淺灰色背景。

• 帶有放大鏡圖像的 UITextfield 帶有以下代碼： UITextField *myTextField = [[UITextField alloc] initWithFrame:CGRectMake(0, 0, viewWidth, 40)]; myTextField.leftViewMode = UITextFieldViewModeAlways; myTextField.leftView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"asdf"]]; myTextField.backgroundColor = [UIColor whiteColor]; UITextField *myTextField = [[UITextField alloc] initWithFrame:CGRectMake(0, 0, viewWidth, 40)]; myTextField.leftViewMode = UITextFieldViewModeAlways; myTextField.leftView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"asdf"]]; myTextField.backgroundColor = [UIColor whiteColor]; 而不是搜索欄。

感謝ezatu丶

您可以將自定義視圖添加到 self.view 並帶來視圖。

這是示例代碼：

#define SCREEN_WIDTH [UIScreen mainScreen].bounds.size.width
#define SCREEN_HEIGHT [UIScreen mainScreen].bounds.size.height

CGFloat margin = 10;
CGFloat viewWidth = self.view.frame.size.width - 2 * margin;
CGFloat viewHeight = 82;

UIView *toolView = [[UIView alloc] initWithFrame:CGRectMake(margin, SCREEN_HEIGHT - viewHeight - margin, viewWidth, viewHeight)];
toolView.backgroundColor = [UIColor grayColor];

UISearchBar *searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, viewWidth, 40)];
[toolView addSubview:searchBar];

CGFloat btnWidth = (viewWidth - 4) / 3;
CGFloat btnHeight = 40;

for (NSInteger i = 0; i < 3; i ++) {
    UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
    [btn setTitle:[NSString stringWithFormat:@"%ld btn", i+1] forState:UIControlStateNormal];
    [toolView addSubview:btn];
    [btn setBackgroundColor:[UIColor blackColor]];
    btn.frame = CGRectMake(i *(btnWidth + 1), 42, btnWidth, btnHeight);
}

[self.view addSubview:toolView];
[self.view bringSubviewToFront:toolView];

您必須在地圖視圖控制器上添加視圖，您可以在其中添加所有按鈕和搜索欄。 並從情節提要中將搜索欄樣式設置為最小值。
