Ios 如何在didFinishPickingMediaWithInfo中的UIImagePickerController之间进行区分
我有两个Ios 如何在didFinishPickingMediaWithInfo中的UIImagePickerController之间进行区分,ios,objective-c,uiimagepickercontroller,picker,Ios,Objective C,Uiimagepickercontroller,Picker,我有两个uiimageview，我想在其中加载两个不同的图像。我有两个按钮，可以触发UIImagePickerController并调用我的 - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info 方法 是否有办法区分上述方法调用的选择器？您可以创建UIButton的实例 @interface YourClass () {
uiimageviewUIImagePickerController- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
是否有办法区分上述方法调用的选择器？您可以创建UIButton的实例
@interface YourClass ()
{
UIButton *_selectedButton;
}
UIImagePickerController-(void)button1Clicked:(UIButton *)button1{
_selectedButton = button1;
// call UIImagePickerController
}
-(void)button2Clicked:(UIButton *)button2{
_selectedButton = button2;
// call UIImagePickerController
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{
if (_selectedButton == button1){
// perform your logic
} else if (_selectedButton == button2){
// perform your logic
}
}
您可以创建UIButton的一个实例
@interface YourClass ()
{
UIButton *_selectedButton;
}
UIImagePickerController-(void)button1Clicked:(UIButton *)button1{
_selectedButton = button1;
// call UIImagePickerController
}
-(void)button2Clicked:(UIButton *)button2{
_selectedButton = button2;
// call UIImagePickerController
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{
if (_selectedButton == button1){
// perform your logic
} else if (_selectedButton == button2){
// perform your logic
}
}
因为我只是试着问同一个问题，所以我也会把我的答案贴出来。我没有使用单独的
