推荐答案

尝试使用此代码在 alertview 中添加复选框.

try this code for add checkbox in alertview.

快速

let nameField = UIButton(frame: CGRect(x: 0.0, y: 0, width: 50, height: 50.0))
let v = UIView(frame: CGRect(x: 0, y: 0, width: 250, height: 40))
nameField.setImage(UIImage(named: "checkbox_off.png"), for: .normal)
v.addSubview(nameField)
var av = UIAlertView(title: "TEST", message: "subview", delegate: nil, cancelButtonTitle: "NO", otherButtonTitles: "YES")
av.setValue(v, forKey: "accessoryView")
av.show()

目标C

UIButton *nameField = [[UIButton alloc] initWithFrame:CGRectMake(0.0, 0, 50, 50.0)];
UIView *v = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 250, 40)];
[nameField setImage:[UIImage imageNamed:@"checkbox_off.png"] forState:UIControlStateNormal];
[v addSubview:nameField];
UIAlertView *av = [[UIAlertView alloc] initWithTitle:@"TEST" message:@"subview" delegate:nil cancelButtonTitle:@"NO" otherButtonTitles:@"YES", nil];
[av setValue:v  forKey:@"accessoryView"];
[av show];
