一行代码实现省市区三级地区选择功能

//选择地区按钮

• (IBAction)selectAction:(UIButton *)sender {

//直接调用

[[[YJLocationPicker alloc] initWithSlectedLocation:^(NSArray *locationArray) {

//array里面放的是省市区三级
NSLog(@"%@", locationArray);
//拼接后给button赋值
[sender setTitle:[[locationArray[0] stringByAppendingString:locationArray[1]] stringByAppendingString:locationArray[2]]forState:UIControlStateNormal];

}] show];

}
