How to add a button on the right side of the toolbar?
提问by SmartTree
I created a toolbar programmatically:
我以编程方式创建了一个工具栏：
UIToolbar *boolbar = [UIToolbar new];
boolbar.barStyle = UIBarStyleDefault;
boolbar.tintColor = [UIColor orangeColor];
[boolbar sizeToFit];
And then added a button to it:
然后给它添加了一个按钮：
UIBarButtonItem *cancelleftBarButton =[[UIBarButtonItem alloc]initWithTitle:@"OK" style:UIBarButtonItemStyleBordered target:self action:@selector(tapBackGround:)];
cancelleftBarButton.tintColor = [UIColor orangeColor];
NSArray *array = [NSArray arrayWithObjects:cancelleftBarButton, nil];
[boolbar setItems:array animated:YES];
However, this button appears only at the left side of the toolbar. Is it possible to put it on the right side of the toolbar ?
但是，此按钮仅出现在工具栏的左侧。是否可以将其放在工具栏的右侧？

In Swift
在斯威夫特
let btn1 = UIBarButtonItem(title: "Button 1", style: UIBarButtonItemStyle.Done, target: self, action: "btn1Pressed"
let flexSpace = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.FlexibleSpace, target: nil, action: nil)
let btn2 = UIBarButtonItem(title: "Button 2", style: UIBarButtonItemStyle.Done, target: self, action: "btn2Pressed")
