我正在尝试添加PickerView-但是我看到黑屏...我在做什么错了???
UIPickerView *myPickerView = [[UIPickerView alloc] initWithFrame:CGRectMake(0, 0, 320, 320)];
[self.view addSubview:myPickerView];
最佳答案
– numberOfComponentsInPickerView:
– pickerView:numberOfRowsInComponent:
和UIPickerViewDelegate方法:
– pickerView:titleForRow:forComponent:
不要忘记设置属性:
UIPickerView * myPickerView = [[UIPickerView alloc] initWithFrame:CGRectMake(0, 0, 320, 320)];
myPickerView.delegate = self;
myPickerView.dataSource = self;
[self.view addSubview:myPickerView];
在.h文件中,请记住输入:
<UIPickerViewDelegate, UIPickerViewDataSource>
我通常使用填充字符串的
NSMutableArray
来填充数据。希望有帮助!关于iphone - 如何为UIPickerView设置数据?,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/14542247/
