我想按标题设置 UIPicker 选择的行,我正在使用下面的代码,但它不起作用,我错过了什么?
// data from sqlite db
test2 =[[NSString alloc]
initWithUTF8String:
(const char *) sqlite3_column_text(statement, 1)];
NSLog(@"%@", test2); // 400 (the value)
[self.myPickerView selectRow:[[[NSUserDefaults
standardUserDefaults]objectForKey:test2]intValue] inComponent:0 animated:YES];
