ios - Objective-C 查找方法的调用者

Question

有没有办法确定调用某个方法的代码行？

Answer 1

堆栈我希望这会有所帮助:

NSString *sourceString = [[NSThread callStackSymbols] objectAtIndex:1];
// Example: 1   UIKit                               0x00540c89 -[UIApplication _callInitializationDelegatesForURL:payload:suspended:] + 1163
NSCharacterSet *separatorSet = [NSCharacterSet characterSetWithCharactersInString:@" -[]+?.,"];
NSMutableArray *array = [NSMutableArray arrayWithArray:[sourceString  componentsSeparatedByCharactersInSet:separatorSet]];
[array removeObject:@""];

NSLog(@"Stack = %@", [array objectAtIndex:0]);
NSLog(@"Framework = %@", [array objectAtIndex:1]);
NSLog(@"Memory address = %@", [array objectAtIndex:2]);
NSLog(@"Class caller = %@", [array objectAtIndex:3]);
NSLog(@"Function caller = %@", [array objectAtIndex:4]);
